Evan,
I wasn't upset, more confused to why you found it incomprehensable.
The advice proffered is genuine. Please consider it accordingly.
If you don’t' get something, ask! We're here to support. Otherwise, we wouldn't
bother.
We don't send out annotated games to brag. We do to educate, to provide
inspiration and hopefully, guidance on how one can improve one's chess.
Cheers,
Chris

Hi Chris,
This is all good advice. But, I was not really serious. Hence the <grin> in my
post.
Sorry you got upset.

I find this a perplexign post.
Neither Tyson nor myself are particularly unclear with our annotations. I admit
that Tyson provides a lot more "variations" based on computer analysis than I
do, but yet, he structures it in sucha manner that is both legible and
accessible. Computer analysis is not always accurate and can only give a glimse
over a position, but he's honest in his appreasal and at the end of the day,
due to his style of play, his games need tactical backup to justify his play.
As for my own annotations, these are principally based on positional values,
which require little calculation and need a bit of appreciation only.
In brief, I'm suspecting that you are not spending enough time reading, and
more importantly, reflecting, on the comments and annotations provided. You
should play through a game first, completely, to get the anticipation out of
the way and then, play it through a second time, once you know the conclusion
and moves, and re-read the notes and in-depth commentary. Do not proceed to the
next comment or commentary, until you have understood, appreciated and
accepted, the reasoning and justification behind the line followed, rejected or
the positional explanation offered. If it is not understood, you should not
proceed and seek clarification or verification, either from the original poster
or from a fellow poster.
Time is essential to play through an annotated game. You should treat it as
reading a book. Spend a lot of time on it. A game of 30 moves should really
take you about 3 to 4 hours to fully go through. 40 moves games should take
even longer. Appreciate them for what they are. Excellent learning resources.
They take hours to produce, so take hours to appreciate them.
This accumulation of small "appreciations" of what is happening and why, will
soon build up. Don't just sit and proclaim ignorance or no ability to
comprehend. For that won't develop your chess in the slightest and is, in fact,
a defeatest attitude. How can anybody improve their chess with such aptitudes
and attitudes?
Chess is a learning curve for the rest of your life. Even I, after 25 years'
worth of tournament chess, am still on the rocky road of learning. Who ever
said that you can't teach an old dog new tricks?
Cheers,
Chris

Hello all
As a follow-on to Chris’s recent post about playing Black against the King’s
Indian Attack, here‘s my contribution. Just castle Queenside and blast open the
Kingside where the White King is. As those pesky meerkats say, “Simples!” Then
again, maybe not.
Regards,
Tyson
Text begins:
. DAVIS, J - MORDUE,A T
SPECTRUM SHEFFIELD, 05.11.2006
This was the last round of a rare all-play-all Open section of a Spectrum
event. I was sharing the three-way lead with 2.5/4 and facing the lowest-graded
player. A win was essential to ensure at least a share of first prize.
1. e4 c5
2. Nf3 e6
3. d3 d5
4. Nbd2 Nc6
5. g3 Nf6
6 Bg2 Be7
7. 0–0 Qc7
8. Qe2 b6
Black announces his intention of castling Queenside. If he intended playing on
the Queenside then the obvious move is 8...b5 claiming more space.
9. e5 Nd7
10 Re1 g5!?
A thematic move that clearly intends to play 11...g4 undoing White's threefold
defence of e5. Now 11 h3 is answered by 11...h5 with the same idea in which
case White would probably play 12 g4. After 12...hxg4 13 hxg4 Black has the
open h-file as an attacking avenue. It is important that White keeps good
control of h2, a theme that occurs later in the game.
11. g4 Bb7
Computers assess this position as slightly better for Black to the tune of
roughly 0.5. The suggested alternatives are the afore-mentioned 11...h5 or
11...Ba6. The latter still intends Queenside play but I wanted to attack on the
Kingside.
12. c4 d4
Normally this locking of the centre would be followed by a slow manoeuvring
game. I was confident I could prevail in that but it is not what occurs.
Here White gains the e4 square but he has to take care that the e5 Pawn isn't
lost to Black's advantage.
13. Ne4!? h6?!
Black would probably do better to take on e5. I was reluctant to enter into
complications with my King still in the centre, and I also didn't really
believe my opponent would switch his Knight to h5, but he did!
14. Ng3 0–0–0
With the Kings castled on opposite side the computers evaluate this position as
equal, but of course it's a dynamic balance. Black has ideas of rerouting his
e7 Bishop to g7 or c7 to pressure e5, while White looks to play b2-b4 in an
attempt to open Queenside lines.
15. a3 Rdg8
16. Nh5 Kb8
17. b3
A slow move that doesn't change anything tangible, but I decided that if White
wanted to be pedestrian then it was time to try some mind games.
17...Re8!?
18. Ng7 Ref8
Now the stoic reply is 19 Nh5 asking Black what the difference is between
having the Rook on e8 or f8. The answer is 19...f5 or f6 when 20 exf6 Nxf6
21 Qxe6? Nxh5 22 gxh5 Rf6 followed by 23...Rhf8 gives Black a big initiative
for White's useless extra Pawn on h5. Better after 19 Nh5 f6 (f5) 20 exf6
Nxf6 is 21 Nxf6 Rxf6 which is still to Black's advantage. His f-file pressure
is worth more than the weakness of the e6 Pawn although White can continue 22
Nd2 and the transfer of this Knight to e4 gives White good defensive chances.
Note that his Rook aids the defence by coming to a2 around the passive Bishop
on c1.
By keeping his Knight on g7 White hinders ..f6(f5) because of the fork on e6.
19. Bd2 h5!?
This is not strictly necessary because 19...Rh7 20 Nh5 f6 or f5 also give Black
good play One difference is that White's second rank is now blocked by his
Bishop. However, the text suggests to White that he has made an error by not
putting the Knight back on h5 and preventing this advance which secures an open
file towards White's King. Strictly speaking it's a semi-open file because
White still has his h2 Pawn, but as demonstrated in the game Black's Rook has
enhanced scope.
20. Nxh5
Deep Rybka confirms my judgement that Black is better after 20 h3 hxg4 21
hxg4 Rfg8 22 Nh5 Rxh5! 23 gxh5 g4 24 Nh2 Ncxe5 25 Bf4 Bd6 and the threat of
26 ...Nf3+ is difficult to meet. The reader is invited to analyse further for
themselves. All the Black pieces are involved in the assault on White's weak
Kingside and the White Rooks do nothing for the defence, justifying Black's
small material investment of an Exchange.
20...Rfg8
Now Black threatens to enter the variation indicated in the last note starting
with 21...Rxh5. Hence White sidesteps but this has the drawback of reducing
control of the f4 square and Black promptly runs a Knight there.
21. Ng3
Deep Rybka approves of the text move but also suggests playing 21 Kf1 and
answering it with the remarkable 21...Ba8. I thought computers had grown out of
this sort of thing!
21...Nf8
22. b4!?
Effectively this is a gambit to open up lines on the Queenside. Certainly it is
okay after 22...cxb4 23 axb4 Nxb4 24 Nxd4, covering the intended fork on
c2 and Black has lost control of the centre. However, there's an important
difference with 22...cxb4 23 axb4 Bxb4. If 24 Bxb4 Nxb4 25 Nxd4 Bxg2 26 Kxg2
Ng6 threatens the fork 27...Nf4+ because the Bishop on d2 has been exchanged
off. Said fork is not only of the White King and Queen but also attacks d3 for
a second time. Black would regain his Pawn with a big advantage.
After 22...cxb4 23 axb4 Bxb4 White's best seems to be 24 Nxg5 Bxd2 25 Qxd2 and
now 25...Nxe5? is neatly met by 26 Rxe5 Qxe5 27 Nxf7 and Nxh8 remaining a Pawn
up. Instead after 22...cxb4 23 axb4 Bxb4 24 Nxg5 Bxd2 25 Qxd2 Black should play
25...Ng6! threatening to safely capture on e5.
Deep Rybka claims that Black is better after 26 f4?! Nh4 and that seems a sound
claim if Black gets to swap off the White Bishop with his own still bearing
down. If 27 Be4 Rxg5! 28 fxg5 Nxe5 and White has big problems with the f3
square again.
22...Ng6!?
Choosing to ignore the Queenside altogether and concentrate on the f4 square.
The game proves why.
Deep Rybka looks at two alternatives here. One is 23 Nh5 - controlling f4 -
when Black can probably take on b4: 23...cxb4 24 axb4 Bxb4 25 Bxb4 Nxb4. Now
both 26 Nxg5?? or 26 Nxd4?? lose to 26...Bxg2 27 Kxg2 Rxh5 because 28 gxh5
Nf4++ wins the Queen.
The other alternative is 23 b5. This closes the Queenside which reduces White's
attacking chances on that side. Black can reply 23...Na5 intending
24...Nb3 and 25...Nxd2 eliminating the defender of f4 again. 24 Bxa5 is
answered by 24...Nf4 of course. After 23 b5 Na5 Deep Rybka analyses 24 Rab1
Nf4 25 Qf1 Ng6 26 Qe2 with a draw after 26...Nf4. Both sides have other lines
to keep the game alive of course.
White chose the natural move, and why not?
23. bxc5 Nf4!
The startled expression on my opponent's face was something to behold. Black
sacrifices a second Pawn to retain the initiative but I saw far enough ahead to
realise that I was getting one Pawn back quickly and improving my attacking
prospects. Recapturing with anything on c5 means White gets to play 24 Nxg5 for
free. Deep Rybka specifically looked at 23...bxc5 24 Nxg5
Ngxe5 25 Bxc6! - a counter-intuitive move but it works here - 25...Nxc6 26
Nxf7 Rh7 27 Qxe6 and White is three Pawns up! Here 23...bxc5 24 Nxg5 Ngxe5
25 Bxc6 Qxc6?? 26 Qxe5 is check and 26... Bd6 27 Qe4 stops the mate on g2.
Also 23...bxc5 24 Nxg5 Ncxe5 is strongly met by 25 Rab1! and the open b-file
bears fruit for White. 25...Nc6 26 Nxf7 Rh7 27 Qxe6 and White gets to take on
c6 as well because the b7 Bishop is pinned. After the text Black's King's
position looks dreadful but White never has time to exploit it in view of the
pressure his own King comes under.
24. Bxf4
The only other move the computer considers is 24 Qf1 but now g5 is defended so
Black can comfortably play 24...Bxc5 with great compensation for his Pawn. Once
again his pieces bear down powerfully on White's weakened Kingside.
24...gxf4
25. cxb6
This capture hits the Black Queen so Black doesn't have time to take on g3.
25...axb6
26. Ne4
Deep Rybka comes up with the interesting 26 h3. After 26...fxg3 27 fxg3 White
has three Pawns for the piece. However, it's not clear that they are three good
Pawns and White's piece activity looks to be limited so Deep Rybka still
evaluates Black as better. Worth trying.
Now Black gets one Pawn back and White flails around trying to get a
constructive defensive set-up.
26...Rxg4
Threatening 27...R8g8 winning the pinned g2 Bishop. The value of the Pawn on
f4 is intriguing. It prevents Ng3 as a shield of the g-file, yet it also blocks
the Black Queen's view of the h2 Pawn.
27. Kh1
Deep Rybka suggests 27 Kf1 instead, but then analyses the same line that comes
up in the next note. I suppose there is an intuitive need to keep defending h2
but the King is now on the same line as an enemy Rook and Bishop.
27...Rg6?!
Deep Rybka suggests after both 27 Kf1 and 27 Kh1 the Exchange sacrifice
27...Rxg2. The line goes 28 Kxg2 Nxe5 29 Nxe5 Qxe5 (threat 30...f5 winning the
pinned Knight) 30 f3 Rg8+ 31 Kh1 f5 32 Nd2 Qe3. Black threatens
33...Qxd2 34 Qxd2 Bxf3+ 35 Qg2 Bxg2+ with two Bishops for a Rook and a winning
ending.
Alternatively 27...Rxg2 28 Kxg2 Nxe5 29 Nxe5 Qxe5 30 f3 Rg8+ 31 Kf1 Qh5 with
the threat 32...Qh3+ 33 Kf2 Bh4+ winning.
It also finds the flashy line 27...Rxg2 28 Kxg2 Nxe5 29 Nxe5 Qxe5 30 Rab1
Rxh2+ 31 Kxh2 f3+ winning the Queen.
These lines are not entirely forced but I was content with the text. The e5
Pawn is about to fall and material will be equal whilst Black maintains his
attack.
28. Ned2?
Going over to blanket defence and missing a chance to possibly create some
play. Deep Rybka suggests 28 c5! trying to reopen lines on the Queenside.
After 28...bxc5 29 Rab1 Kc8 unpins and keeps the initiative but Black now needs
to be wary of Rxb7 counter-sacrifices. Obviously ..Rxg2 will rule out any
danger but Black could have played that last move.
Deep Rybka says there is some value in giving the other Pawn back with 28
Nd6 Bxd6 29 exd6 Qxd6 to swap off a Black Bishop but that's not the dangerous
one.
The shock value of 23...Nf4 is having its effect as White is reacting instead
of acting.
28...Rhg8
29. Rg1
If 29 Bh3 Deep Rybka suggests the consolidating 29...Bc5 and, what would have
been my choice, 29...Rh8 30 Bg2 Rh5 when e5 should collapse. White can't play
30 Nxd4 exploiting the loose Rook because of 30...Nxd4 31 Qxh5
Bxg2+ 32 Kg1 Bf3+ winning the Queen.
29...Nxe5
Now that the White Rook has gone from e1 this capture is possible because of
the line 30 Qxe5 Qxe5 31 Nxe5 Bxg2+ 32 Rxg2 Rxg2 and Black has won the
Exchange. Oddly Deep Rybka thinks that this is White's best line.
30.Bh3 Rxg1+
Here Deep Rybka thinks the immediate 30...Rh8 is better. It's right because of
the line 31 Rxg6 Rxh3! 32 Rg8+ Ka7 and the pinned Knight on f3 perishes.
I hadn't seen 31...Rxh3. After 30...Rh8 White should play the better 31 Bg2
upon which Black replies 31...Rgh6 and White hasn't swapped off his inactive
a1 Rook as in the game.
31. Rxg1 Rh8
32. Bg2 Ng4
Despite the Rook swap Black still has a great position. Ironically the a3 Pawn
is now en prise although it's not clear Black wants to take it.
My plans were to either get the Queen to the h-file or advance the central
pawns to usurp the Knight on f3. The obvious way to do the first is the switch
...Qc7-c5-h5 so maybe my opponent's next move was to prevent this.
Unfortunately it's a blunder. Maybe 33 Nf1 hangs on for a while but White's
formation does not look inspiring.
33. Nb3?? Bxf3
White can lo longer recapture with a Knight to guard h2. The mate there can
only be avoided at a huge cost in material.
34 0–1
