Hello Che et al,
Below are my notes to Che's game against the engine at level 4. I have kept
Che's notes so the reader can compare the two.
There are some blunders here, but there are good moves too. I get the
impression Che underestimates how strong his attack is, but one of the
instructive points is that White's Pawn a2-a3 actually helps Black's attack
significantly. The engine plays poorly and misses several chances to stake a
clear advantage and, frankly, gets what it deserves.
Have fun!

Lichess,4 - Che [A00]
19.03.2021
[Mordue,Tyson]
1.Nc3
[Che: White starts with a move I'm not used to, so right off the bat, black is
in improv [improvisation] mode.
TM: 1 Nc3 is an awkward first move to meet. My favourite reply is 1...c5 but
only because I know the Sicilian Defence after 2 e4, and then again this is the
Closed Variation normally reached by 1 e4 c5 2 Nc3. ]
1...e5
2.Nf3 d5??
[Blundering the e5 Pawn which White fails to take until the move after next!
Sensible moves are 2...Nc6 and 2...d6, but the latter means that after 3 e4
Black is playing the Philidor Defence (1 e4 e5 2 Nf3 d6) which is a bit
cramped.
This is the whole point of 1 Nc3. It's an attempt to get by transposition into
opening lines that he Black doesn't know.]
3.d4?? Nc6??
[Repeating the mistake of the previous move. Simply good is 3...e4 gaining a
space advantage and a tempo on the f3 Knight. ]
4.Nxe5 Nxe5
5.dxe5
[Che: So this is off to a massacre already, I was at this point just going
ahead to see how level 4 Stockfish reacted to my bumbling attacking opening
moves and try to take some lessons from the reaction.
TM: Hardly a massacre, but it could have been in a few moves time. The opening
moves weren't attacking but simply a standard occupation of the centre.
However, the e5 Pawn was left en prise twice and a good opportunity to advance
it ignored.
As for looking to take some lessons from Stockfish at this level, well it
doesn't seem to be a good teacher. Right now the d5 Pawn is en prise so Black
should defend that, either directly by 5...Be6 or 5...c6 or indirectly with
5...Bb4 pinning the c3 Knight. There is a point to attacking the White central
Pawn as 6 exf6 Nxf6 develops and defends the d5 Pawn. However, the position is
already dangerously open and Black could well go two Pawns down for nothing if
he's not careful. ]
5...f6?
6.e3
[This is a modest, second rate move that has a big touch of poison.
White can simply take on d5 with either Queen or Knight and go two Pawns up.
I'd choose the Queen. After 6 Qxd5 fxe5 7 Qxe5+ White is two Pawns up with the
better position. Instead 6 Qxd5 Qxd5 7 Nxd5 and now 7...fxe5 loses a whole Rook
after 8 Nxc7+. Now after White has taken on d5 with anything White has the
option to go e2-e4 in one go. This takes more space and doesn't obstruct the
Queen's Bishop as the text does. That's why I call it second-rate.
Now once again Black should defend the d5 Pawn with any of the moves given in
the previous note. Unfortunately he falls into the trap.]
6...fxe5?
7.Qf3?
[This is two opportunities missed at once. Obviously either capture on d5 means
that White stays a Pawn up.
First I draw your attention to the following game: Rigaud vs Cooper, Nice
Olympiad 1974, Round 1. It went 1. e4 e5 2. f4 d5 3. fxe5?? Qh4+ 4. g3 Qxe4+ 5.
Kf2 Bc5+! Very embarrassing for White. Black declines the whole Rook in the
corner and instead forces White to lose even more material after 6 d4 Bxd4+. He
probably has to give up his Queen to avoid mate. Hence 0–1.
In this position 7 Qh5+ is crushing for the same reasons. Loss of material,
loss of castling rights, general disorganisation but, fortunately, not
world-wide notoriety for the quickest and first loss of an entire Olympiad!
Best is 7...Kd7 8 Qxe5 c6 limiting the losses to one Pawn, but after 9 e4
opening the centre Black is in a lot of trouble. For example 9...dxe4? 10 Bg5
and 11 0–0–0+.]
7...Nf6
[So incredibly Black has got away with it and Deep Rybka says this position is
equal.]
8.Qg3
[This is a tricky little move because it threatens to take on e5 again and it
seems that the natural defence of 8...Bd6 leaves the g7 Pawn en prise.]
8...g6??
[This is a bad move for several reasons. First it leaves the e5 pawn en prise
and this time White takes it, albeit a move later than he should do! Secondly
it weakens the Kingside for no particular reason. Later on f6 becomes a
sensitive spot. Thirdly there is an adequate defence to the e5 pawn with
8...Qd6.
However, Deep Rybka comes up with a nice line here. We had an early scenario in
Paez vs Lichess 1 where the engine forked Pawns on g2 and e4. I said it should
have captured on e4 as the central Pawn was more important. It actually took on
g2 and Deep Rybka said that after 9 Rg1 White had control of the open g-file
and good compensation for the Pawn generally due to his superior position in
the centre. Right here Deep Rybka suggests 8...Bd6 and if 9.Qxg7 Rg8 10.Qh6 Bf5
which is fair, but also the intriguing 10...Bf8!? 11.Qh4 Rg4 12.Qh3 d4! This is
well worth looking at. The White Queen has spent a lot of time pinching one
Pawn while Black's position has improved. What's more White can't play 13
exd4?? here because 13...Re4+ wins said Queen because it's en prise to the c8
Bishop.
There's an old adage that goes "One should never take the Queen's Knight Pawn
(the b Pawn) with the Queen." Sometimes the same thing applies to the King's
Knight Pawn (the g-Pawn) and that seems to work here, so the sharpest reply is
8...Bd6. If White fails to take on g7 Black should be able to castle next move
with a fine position.]
9.e4!?
[Simplest is to just take on e5 immediately. The text invites Black to play
9...Nxe4?? 10 Nxe4 dxe4 when after 11 Qxe5+ he loses the h8 Rook courtesy of
the poor 8...g6.
Black's best reply is 9...Bb4 developing and pinning the c3 Knight. In turn
this invites White to make a blunder with 10 Qxe5+ Kf7 11 exd5?? Re8 dropping
his Queen.]
9...c6?!
[Che: Perhaps the better move would have been NFD7 to avoid queen coming in to
take pawn on E4.
TM: 9...Nd7 is an awful move. It blocks the Queen and Queen's Bishop and leaves
the d5 Pawn hanging to 10 Nxd5. The move 10 Bg5 first is also strong: 10...Be7
11 Bxe7 Qxe7 12 Nxd5 Qd6 (to guard c7 and also an echo from Paez-Lichess 1.) 13
0–0–0 and 14 Bc4 is very good for White.
The text has some merit as if defends the loose d5 Pawn, but Black has had two
chances to develop his King's Bishop to an active square and he making Pawn
moves instead.]
10.Qxe5+ Be7
[So it's this modest square instead of d6 or b4.]
11.Bg5
[Not bad because it threatens 12 Bxf6 due to the pin - remember that ....g7-g6
weakened f6 - but 11 Bh6 preventing 11...0–0 is so much better - ...g7-g6
weakened h6 as well!]
11...0–0
[Che: Seemed like it was past time to get back to some fundamentals of the
opening and try to stave off mate for a while.
TM: Very true. Castling by both sides is okay and the pressure on d5 is
increased by White. The downside is that Black's King is much draughtier that
White's.
An interesting and ironic feature comes up in the next few moves. Both sides
have a Rook and Bishop which have yet to be developed. White never develops his
lazy pair. Che devises a plan of all-out advance on the Queenside in which the
Rook soon plays a dominant role, and the Bishop joins in the fun later.
It may be that Black had better things to do than advance Pawns instead of
getting these pieces out, but he had a plan and he stuck to it. Attacking the
enemy King can be quite a dangerous thing for the opponent especially when they
don't seem to have a plan themselves. Hence the adage "a bad plan is better
than no plan."]
12.0–0–0
[Che: Looks like White agrees with my previous sentiment.]
12...Re8!
[This is a good defensive move. The pin on the h4-d8 diagonal is awkward and
Black's d5 Pawn is in danger of going for nothing. There's a natural line that
goes 13.exd5 Nxd5 14.Bxe7 Qxe7 15.Qxe7 Nxe7 16.Bc4+ which leaves White a Pawn
up in an endgame with a lead in development. Deep Rybka says White is +1.45
which is good for him. Yet it's also good for Black because he hasn't lost a
second Pawn, he's resolved the situation in the centre and he's actual got a
solid position despite the Pawn minus. After all the things that could have
happened this is a fair outcome! ]
13.f3
[This is okay as well. It supports the e4 Pawn and apparently rules out the
awkward ...Nf6-g4. Discoveries with the e7 Bishop don't work while f6 is loose
so Che starts a Queenside advance. As I said, it's a plan.]
13...a5!?
14.Qd4!?
[Deep Rybka suggests 14 h2-h4 attacking on the Kingside with an evaluation of
+1.84. That's good as the g6 Pawn is sticking out so White makes faster
progress on the Kingside than Black does on the Queenside, and the h1 Rook is
in the game.
So what is the Queen move about? It gets out of the reach of the Black Rook on
e8 but as explained in the previous note that's not a problem. However, it does
threaten to take on d5 with 14 exd5 Nxd5 (if 14...cxd5 then 15 Bxf6 and 16
Qxd5+ Qxd5 17 Nxd5 wins a second Pawn for nothing) 15 Bxe7 and now 15...Nxe7??
loses a whole Rook to 16 Qxd8 because the Black Rooks aren't connected, while
15...Qxe7 16 Nxd5 is just winning another Pawn again. Now if Black plays the
simple 14...dxe4 because his Queen is no longer en prise directly to the d1
Rook, White plays 15 Bxf6 winning a piece. This is because because 15...Qxd4 is
answered by the backward recapture 16 Bxd4, while the simple recapture
15...Bxf6 loses to the sidestep 16 Qc4+ - also hitting Black's Queen - 16...Be6
- hitting White's Queen - 17 Rxd8 Bxc4 and now 18 Bxc4 is check. This is called
a zwischenzug or inbetween move during an otherwise forced sequence that makes
a significant difference. So it looks like after the text Black must play
14...Be6 to reinforce d5. ]
14...b5?
[Che: Black is looking to run some suicide squad pawns across enemy lines since
white castled queen side.
TM: Note that Black now has only one Pawn remaining in his second rank so his
position is wide open to a sensible attack. As for Black's Queenside attack
White has no weaknesses on that wing, unlike Black who has g6 sticking out on
the Kingside and is vulnerable to h2-h4-h5.
At this point White can take on d5 - 15 e4xd5 - with comfort and this wins a
second Pawn as shown in the previous note. There is only one additional line.
After 15 exd5 there is 15...b5-b4 hitting the White Knight on c3 and hoping it
moves so Black could play 16...Nxd5 with ease. Unfortunately White just ignores
it with 16 d6! dxc3 and then Deep Rybka finds the fine 17 Bc4+! Kg7 18 Rhe1!
with the entire White army developed and centralised. 19 Rxe7+ followed by
taking on f6 with Queen or Bishop is a huge threat. It says this is +6 for
White. Once again the lack of connection between the Black Rooks is a factor.
This is proof that Black really should have played 14...Be6. Ignore development
at your peril!
In the above line Black has the move 18...cxb2+ and White should just ignore it
and play 19 Kb1. This is a reasonably common scenario where the enemy Pawn
actually shelters the White King. See later on. Just because something can be
taken doesn't mean that it should be.]
15.Qe3??
[This is a bad move for two reasons. One is that it eschews the chance to play
the natural and strong 15 exd5 as explained in the last note. Secondly it
allows a strong tactical shot based on the fact that the White King and Queen
are on the same diagonal. 15...Ng4! attacks the Queen and 16 fxg4?? loses the
Queen after 16...Bxg5. Note that an earlier h2-h4 would have defended the
Bishop. Another good chess adage is that "loose pieces drop off".
So after 15...Ng4 White must play 16 Bxe7 and then we have 16...Nxe3 17 Bxd8
Nxd1. At this point the material imbalance is that White has lost a Rook for a
Bishop and Pawn, not a serious deficit by any means and both sides have a minor
piece en prise. There's a quaint line that goes 18 Bxa5 - selling itself as
deeply as possible and it's called a desperado. Black can desperado himself
with 18...Nxb2 or he can play 18...Nxc3 19 Bxc3 Rxa2, but best is 18...Nf2
attacking the other Rook ans winning more material.
Best according to Deep Rybka is the simple 18 Kxd1 Rxd8 19 e5 when White has
drawing chances. Not good is 18 Bf6 Nxc3 19 Bxc3 dxe4 and Black gets his Pawn
back to emerge a full Exchange up.
After 15 Qe3 Deep Rybka's evaluation swings from +2.35 if 15 exd5 had been
played to - 0.92 after 15...Ng4. That's a swing of 3.27 and that's more that
the worth of a minor piece. Now you can see why I've given it a double question
mark. However, Che misses his tactical chance but still comes up with good
strategical move. ]
15...a4!?
[Okay, so it's a missed opportunity but it's the right move on the Queenside.
If 15...b4 then the reply is 16 Na4 and it's difficult to made progress. By
playing this move first White is denied that chance.
However, he can now play 16 exd5 when the simplest line is 16...Nxd5 (not
16...cxd5 17 Bxb5) 17 Bxe7 Qxe7 18 Nxd5 Qxe3+ 19 Nxe3 Rxe3 20 Rd8+ with an
extra Pawn in the ending for White. Alternatively there is 17...Rxe7 but
Black's position is awkward after 18 Qc5.]
16.a3?
[This is a repeat of the same tactical error and a missed opportunity and a
strategical error. We've already established that 16 exd5 is a good move. So is
16 h4 defending the g5 Bishop and starting a Kingside attack. Also Kb1 at some
point, including right now, is useful because it defends a2 and gets the King
off the same diagonal as the Queen.
However, with Black pushing on the Queenside the last thing White wants to do
is move Pawns there too. a2-a3 may delay ...b5-b4 but when it does arrive it's
makes contact with a3 and lines will be opened. The simplest way to play the
Queenside Pawns is to do nothing except maybe a precautionary Kb1, let Black
play ...b5-b4-b3, take c2xb3 and after ...a4xb3 play a2-a3 sealing the
Queenside unless Black wants to start saccing pieces on a3. Black does have an
alternative after c2xb3 which is to play ...a4-a3 and have two half-open files
for his heavy pieces. Whatever scenario plays out White should be okay given
his better control of the centre
Please note that this is another poor Pawn to Rook Three, and this time there
are several reasons for it being bad.]
16...Rb8
[Che: I don't recall what I was thinking here, perhaps a later attack on the B
file, but I should have checked that G5 bishop first.
TM: The g5 Bishop isn't a problem in relation to the Queen's Rook, and again
16...Ng4 is good. Most of the same variations apply as the moves a2-a3 and
...Ra8-b8 don't really change the tactical situation. However, they do add
grist to Black's mill on the Queenside.]
17.Bf4?!
[This removes the tactic with ...Ng4 but it reduces the pressure on d5 because
White no longer has the option of Bg5xf6.
The attack on the Rook is slightly irritating but it's easily dealt with. Black
has options of 17...Rb7, 17...Rb6 and 17...Bd6. I don't like 17...Rb6 because
it ties the Black Queen to it's defence because it's attacked by the White
Queen. I'd want to keep pieces on the board because Black is a Pawn down, so
avoid exchanges hence I wouldn't choose 17...Bd6. Also that Bishop is pointed
at White's King and the f4 Bishop doesn't seem to help in the defence. So I'd
play 17...Rb7. It may also help lateral defence of the Kingside because the
second rank is clear of Pawns.]
17...Bd6
[Nevertheless Deep Rybka says this is the best move so I can't criticise Che's
choice. It also means that the Rook on e8 is pinning the e4 Pawn to White's
Queen so that momentarily reduces the pressure on d5.]
18.Kb1?
[Deep Rybka doesn't like this and neither do I, and it's all to do with that
Pawn on a3. The break (some players call these levers) ...b5-b4 is coming and
as lines are certain to be opened I'd rather not have the King on the b-file.
Deep Rybka suggests first the odd 18 g3 which at least defends the Bishop if
the White Queen moves away, but it's simpler just to swap Bishops which is what
I'd play. The engine's second suggestion is far more sensible, namely 18 Be2
connecting the Rooks. e2 isn't a great square for the Bishop but having the
Rooks connected is more important.]
18...Qc7
[Che: Perhaps better to move queen to B8, and possibly trade queens here? A
thought, would at least get the B rook closer to the fray.
TM: This is a bit confusing. The Black Queen can't go to b8 because the c8
Bishop is in the way. Maybe Che meant b6 because of the Queen trade but there
are several things against that. First Black is attacking so he doesn't want to
trade Queens. Secondly White's Queen is on an awkward square while Black's has
potential on the Queenside. a5 is the square that I'd be putting it on.
However, the main point is that after 18...Qb6?? 19 Qxb6 Rxb6 20 Bxd6 Black has
lost a piece.
The Rook on b8 doesn't need to get 'closer to the fray' if ...b5-b4 opens that
file. Rooks want open files to work on, although for birthday presents they
like to be doubled on the seventh rank. So the best move here is to get on with
the attack by 18...b5-b4. There's a little bit of intriguing geometry here
because after 19 Nxa4 bxa3 obviously White can't play 20 b2xa3 because of the
b-file pin, nor would he want to, but he can't play 20 Qxa3 because of the d6
Bishop, and should he play 20 Bxd6 Qxd6 then he still can't play 21 Qxa3
because 21...Qxa3 again exploits the pin on the b-file.
The best line is 18...b4 19 Nxa4 bxa3 20 b3 Bxf4 21 Qxf4 Be6 and Deep Rybka
evaluates this position as equal. White still has his extra Pawn but it's
effectively the one on f3 so it's not doing anything. I like Black's attacking
chances so I prefer the second player, but I'd like so much to have that g6
Pawn back on g7.The text attacks the Bishop on f4 so White should simply gain a
tempo by swapping on d6.]
19.Bg5!?
[An interesting move that is also recommended by Deep Rybka. It suggests the
reply 19...Qf7 which is okay. Should the sequence ...b5-b4, Nc3xa4 b4xa3, b2-b3
Bc8-e6 ever happen then Black is going to play ...d5xe4 and then probably
...Be6xb3 destroying the White King's cover. In the current circumstances c2xb3
is answered by ...Rb8xb3+ forking the White King and Queen. Yes, this is
several moves away but it proves that the White Royalty are not on safe
squares. I played an analogous position in a 4NCL game where I had doubled
Rooks on the b-file and 'sacrificed' on b3 when it was defended by a Pawn on a2
and the Queen on c3. My unfortunate opponent had missed that the Rooks were
supported by the Black Queen on f7 and got massacred. Beware of defensive moves
that are actually attacking moves, particularly if they are by the Queen which
radiates in several directions.]
19...Nh5?
Che: The thinking here is to defend the f6 square, but probably not tactically
sound to have knight limited by the edge of the battle field.
TM: "A Knight on the rim is always dim" is another common adage. This move
gives White the chance to play g2-g4 forcing the Knight to g7 and follow up
with h2-h4.Deep Rybka also finds a tactic. It goes 20 Bxb5! cxb5 21 Nxd5 Qc6
22 g2-g4 Ng7 23 Nf6+ Kh8 24 Rxd6! Qxd6 25 Nxe8 Nxe8 26 Bf4 Qb6 27 Qc3+ Kg8 or
Ng7 28 Bxb8 Qxb8 29 Rd1. White ends up with Rook and three good Pawns for two
miserable pieces and great control of the position.
This line is not completely forced. Black can try 20...Rxb5 and immediately
give up the Rook for two pieces, and he can try other squares for the Queen at
move 21 but he must keep an eye on the d6 Bishop. It's worth a closer look
because it takes advantage of the slightly unco-ordinated state of the Black
pieces. What's more after 21 Nxd5 White has three Pawns for the piece and
Black's extra piece is that awful Knight, so it must be good value for White.
Another point here. Che says that it's " probably not tactically sound to have
knight ... (on)... the edge." Generally it's not strategically sound either
unless the Knight is on a journey somewhere. See the game Nimzowitch vs
Rubinstein, Dresden 1926 where the former starts a Knight tour with the move 18
Nh1. Given a chance in the present game the steed might get to f4, but in the
above combination 21 Nxd5 puts extra control on f4 so the Knight must go to g7
after g2-g4.
All the chess 'rules' and tenets have exceptions and I have in my praxis
(Nimzowitch again!) a game where I play, as Black, both ...Na5 and ...Nh5. But
the particular circumstances enabled me to do them both safely and they were
headed to good squares. Thinking about this led me to looking at the line 20 g4
Nf4, but that's an error because of 21 e5! Bxe5 (if 21...Rxe5 22 Qxf4) 22 Bxf4.
Now 22...Bxf4 doesn't work because there's no pin - the White King is on b1,
not c1 - and White has 23 Qxe8+ due to the lack of connection between the Black
Rooks.]
20.Qg1?
[At first I thought this was incomprehensible, then I understood that it
defends the h2 Pawn against the twofold attack on the h2-b8 diagonal.
Regardless, it's an awful move that buries the Queen in a corner on the wrong
side of the board. And White had several other good moves!
Not surprisingly Che now takes the initiative on the other side of the board.]
20...b4!
[Che: This is what the kids today call a blunder.
TM: Hopefully the kids today know better. The kids I coach do. This is the
thematic breakthrough and Deep Rybka says Black is better by +0.46. I wonder
why Che thinks it’s a blunder.]
21.Nxa4 bxa3
22.g4?
[It has to be 22 b3 to shore up the Queenside. White is fiddling on the
Kingside while his King position burns. And that was Nero, not Nimzowitch!]
22...Qa5
[Che: This move to avoid an attack from white queen to A7, and to get the black
queen in the thick of things.
TM: I once had to bring a Black Queen into an attack via a8 because the White
Queen was controlling a5. It was at a BCA event so I had to announce the move
and it caught the attention of several people who wondered what I was doing.
Her Majesty soon arrived on a4 though and Black won shortly afterwards.
Here Black simply threatens 23...Qxa4 even if White replies 23 b3. White's
reply is a crashing oversight that should end the game as a contest. ]
23.Qd4??
[Che: And now the white queen is also in the thick of things.
TM: Actually it's right in the firing line. However, if 23 b3 Qxa4 24 gxh5??
Rxb3+ 25 Kc1 (if 25 Ka1 Be5+ or 25 Ka2 Rb2+ win.) 25...Qb4! - threat 26...Rb1
mate - 26 cxb3 Qc3+ 27 Kb1 Qb2 mate. There are no White defenders. ]
23...Rb4
[A simple and winning fork. Deep Rybka has Black at +4.85.]
24.Qc3 Qxa4
[This is okay but even better is 24...Rxb2+! because the Knight is overloaded
defending b2 and c3. After the text White has no time to take on h5 because of
25...Be5.]
25.Bh4??
[Ah, the sweet sound of violins. This move does precisely nothing.]
25...a2+?!
[Che: Black is trying to keep constant pressure on white and hopefully gain
some material in the process.
TM: Black should be trying to finish White off! He already has an extra piece.
Taking on b2 is also good. After 25...axb2 Black threatens 26...Qa1 mate so
White will have to play 26 Qxb2 giving up his Queen. After 26...Rxb2+ 27 Kxb2
Be5+ 28 Kc1 (if 28 c2 Qb4+ ates shortly) 28...Bc3 forces mate on a1.
The text forces 26 Ka1 and the enemy Pawn is now sheltering the White King.
However, b2 is too weak so Black is winning anyway. There are lots of long
range attackers – the c8 Bishop will come to e6 allowing the e8 Rook to move
over to the Queenside - and a dearth of any sort of defenders. The f1 Bishop
and h1 Rook never move.
26.Ka1 dxe4??
[Che: I considered D4-D5 to put pressure on the queen, but the thinking was I
might get a promoted pawn down the line possibly.
TM: I assume Che means 26...d5-d4 but in fact 26...Be5 is unanswerable. The
text unfortunately leaves the Bishop on d6 en prise.]
27.gxh5??
[Che: I'd like to say I sacrificed that knight on purpose instead of simply
forgetting about the attack which I had looked at earlier. I'd also like a pony.
TM: Elephants are much more fun than ponies. (The Russian word for Bishop
translates as elephant!)
After 27 Rxd6 White is better in this messy position. Instead he takes the one
Black piece that wasn’t doing anything, Che now finds the right move and the
roof caves in.]
27...Be5
[Che: A little more pressure on the royal family.
TM: Have you seen the news recently?]
28.f4
[Che: Take note, Stockfish level 4 makes incredible blunders as well. I checked
this move for 2 solid minutes before taking the queen, thought for sure I was
missing something.
TM: Going down with a whimper. Deep Rybka offers 28.Bc4+ Rxc4 29.Qb3 Qxb3
30.cxb3 Rc2 with an extra piece and a winning attack for Black.]
28...Bxc3
[Che: Down goes Frazier!
TM: Daily Blog Headline. Her Majesty fatally attacked by Rogue Bishop. Film at
ten!]
29.bxc3 Qxc2
30.cxb4
[Che: Speaking of blunders…
TM: Not sure about this comment. Black certainly hasn't blundered. The Rook on
d1 is en prise and Black can mate without even having to take it! ]
30...Be6!
[Che: Covering the A2 square.
TM: With the threats 31...Qc3 mate and 31...Qxd1+ 32 Kb2 a1=Q mate. Black can
play both of these in the next few moves!
Also good enough is 30...Qxd1+ 31 Kxa2 Be6+ and the White King gets caught in
the crossfire of Queen, Bishop and Rook, but the text is accurate.]

Hi all,
I'm trying to analyze my own games to see where I am going wrong and right,
and where I can make improvements.
Below is a game I played yesterday on liChess against old man Stockfish.
Apparently at level 4, it still makes bad blunders, though not as many as
level 3.
I've looked up relative ratings, and Stockfish level 4 is supposed to be
around 1600, but there is no way a human player with ELO anywhere around 1600
would have done some of the things you'll see in this game.
One thing I learned is with my memory, I need to review my own games
probably the same day, if not right after I play them.
Anyhow, as a beginner chess player, if I could get some analysis on my
analysis, constructive criticism and the like, that would be great as I'm not
sure the best way to think about and annotate one's own games.
Thanks much,
Che

So this is off to a massacre already, I was at this point just going ahead to
see how level 4 Stockfish reacted to my bumbling attacking opening moves and
try to take some lessons from the reaction.

Perhaps the better move would have been NFD7 to avoid queen coming in to take
pawn on E4.

Seemed like it was past time to get back to some fundamentals of the opening

Looks like white agrees with my previous sentiment

Black is looking to run some suicide squad pawns across enemy lines since
white castled queen side

Is white looking to break the queen through the pawn chain on queen side?

file, but I should have checked that G5 bishop first

Perhaps better to move queen to B8, and possibly trade queens here? A
thought, would at least get the B rook closer to the fray

The thinking here is to defend the f6 square, but probably not tactially
sound to have knight limited by the edge of the battle field

This is what the kids today call a blunder

This move to avoid an attack from white queen to A7, and to get the black
queen in the thick of things

And now the white queen is also in the thick of things

Black is trying to keep constant pressure on white and hopefully gain some
material in the process

I considered D4-D5 to put pressure on the queen, but the thinking was I might
get a promoted pawn down the line possibly.

I'd like to say I sacrificed that knight on purpose instead of simply
forgetting about the attack which I had looked at earlier. I'd also like a

A little more pressure on the royal family

Take note, Stockfish level 4 makes incredible blunders as well. I checked

Hello everyone.
So I decided to take it up a level today and play Stockfish level 2.
There were a few ridiculous moves on Stockfish’s part that I’m sure Tyson
will find but other than that it was a good game.
Notes and PGN attached below.
Just as an FYI since I forgot to add it yesterday, my classical games are
60/8, 60 minutes per side with an 8 second increment per move from move 1.
Jorge
