Chris et al.
Thanks for the correction and the game.
In my own game at move 14 I probably already had the idea of ...Bd3 simplfying
so didn't want to lose a tempo with...Bg6. There's probably little difference
though. Note that White's d3 square became weak as a direct result of playing
c2-c3. This is what we mean by potential weaknesses, and this one became
reality. Also note that after 23 h3, an innocent enough move in itself, Black
subsequently went 24...Qb7 with the threat of 25...Rxh3+ because the g2 Pawn is
pinned. The reply 25 Kh2 solves that problem but it means the e5 Pawn may be
taken with check, a fact my opponent forgot when he blundered with 31 Qg2.
Chris's game is clear enough. Note the weakening effect of another Pawn to Rook
three, namely 17...h6? This just added to the effect of g4-g5 when White did
get to play it. Note also the effect of Queenside castling. The Rook lands on
an already open file and there is an instant threat of 11 Bb5+ winning the
Black Queen. If 10...0-0 then 11 Bxh7+ with the same result. Black's problems
come as a result of opening the centre with 7...e5 whilst still uncastled.
I have just recalled the (correct) other game I intended posting on this thread
and will put it on shortly. It really does make f3 look like a bad move!

Tyson et al,
I agree with all that Tyson has said below, especially so with the move
f3. Although the e3-square is weakened after 2. F3, it is not a fatal
weakness. It is more a point of focus that can be looked at later.
I am more convinced if black has not played d5. So, in the sequence
1. D4 Nf6 2. F3
where I think 2... c5 certainly puts pressure on the dark-squares.
Playing 3. D5 there might lead to Bennoni positions, where f3 may not be
helpful.
Note in Tyson’s game below, black’s 17th move is Rd8.
Move 14... Kh8 is strictly not necessary either.
White does have vague threats of Bh6, but the pin on the g7 square can be
covered up by a retreating light-squared bishop from f5 to g6. Black would
have done best with 14... Rad8 or some advancement with the queen-side pawns.
Interestingly, Tyson’s game was played before I was born!
A search through my own database shows me that I indeed dabbled with the
Blackmar myself as white in a couple of games. To my chagrin!
I give an example of my endeavours with this opening below, but please
note that I’m not advocating this opening for white!
In my game, I played Bd3, which is somewhat unusual. The bishop usually
goes to c4. Indeed, a game of mine shortly before this example went Bc4 and
black allowed Bxf7+ and Ne5+ picking the piece back up on g4.
The opening is certainly suspicious as I played it, but I got the attack
and the finish is neat enough. White will simply take on g7 and then mate on
f7.
Begs the question to where my attacking style in the 90’s went?!

Hello everyone.
Apologies for being late to the party on this one.
The move f2-f3 does appear in some opening lines, particularly the
Samisch varaition of the King's Indian Defence (1 d4 Nf6 2 c4 g6 3 Nc3 Bg7 4
e4 d6 5 f3), the Grunfeld Defence (1 d4 Nf6 2 c4 g6 3 Nc3 d5 4 cxd5 Nxd5 5 e4
Nxc3 6 dxc3 Bg7 7 Bc4 c5 8 Ne2 0-0 9 Be3 Nc6 10 0-0 Bg4 11 f3), the Pirc/
Modern (1 e4 d6 2 d4 Nf6 3 Nc3 g6 4 f3) and also the French Defence (1 e4 e6
2 d4 d5 3 Nc3 Nf6 4 f3.
If the sequence is 1 d4 d5 2 f3 then it suggests that White is going to
play the Blackmar-Diemer Gambit which is usually reached by the more direct 1
d4 d5 2 e4 dxe4 3 Nc3 Nf6 4 f3 exf3 5 Nxf3. This is playable but it is
virtually non-existent in Grandmaster praxis. My own praxis has one game
given below. I thought that I had a serious game where my 2200-rated opponent
opened with 1 f3 but I seem to have been mistaken.
With White having played early moves witrh both the d and f Pawns then
there is the potential for the e3 square to become weak, but it is only
potential. If White chooses the Stonewall attack which includes both d2-d4
and f2-f4 then I would opine that the e4 square is a definite weakness as it
nearer to Black's side of the board - 1 d4 Nf6 2 f4 Ne4 makes the point in
direct fashion! However, e3 is deeper into White's position and hence easier
for him to defend. Regardless, the exploitation of any weak square depends on
the avaliibility of attackers and defenders for occupation or simply control
of said square.
Back to the Blackmar-Diemer Gambit, even if it wasn't mentioned by name
in previous posts. One point that I have to disagree with is the following
made by David: "With the Queenside already opened up from move 1, Queenside
castling will eventually prove to be a liability if played." This is not
correct. 1 d4 is a central Pawn move. It does not weaken the Queenside and
Queenside castling is a regular feature of the Blackmar-Deimar.
By the same token after 1 e4 e5 2 f4 - the King's Gambit - White
regularly castless KIngside but it is not clear whether one could describe
the KIngside as weakened. However, if you play moves such as Pawn to Rook
Three (h2-h3, a2-a3, h7-h6, a7-a6) or Pawn to Knight Three (g2-g3, b2-b3,
g7-g6, b7-b6) without good reason then these may be regarded as weaknesses.
Generally speaking the ideal castled position consists of King on Knight one
(b1, g1, b8, g8), the three Pawns directly in front of the King unmoved, and
a Knight on Bishop three (f3, c3, f6, c6). All these, of course, depend on
circumstances. Fianchettoes, involving moving the Knight's Pawn forward one
square, are acceptable with the Bishop placed on Knight two.
I give the game below so that you can see what a Blackmar-Diemer gambit
looks like. At the time I wasn't playing the King's Indian Defence, indeed it
was my first full season of league chess, so i chose 2...d5 to stop White
playing 3 e4 with a possible Pirc Defence after 2...d6 and 3 ...g6. However,
my opponent played 3 e4 anyway! I'm not annotating this game although anyone
else is welcome to. I'll merely point out that White's attack never really
takes off and the weak e5 Pawn needs constant attention. Swapping off so many
pieces didn't do White any favours either.

Evan and all,
What Chris points out is excellent advice. Contrary to what some
will
say, there are good and bad opening systems, especially among the
more
obscure ones. The trouble for us club level players to discern is
what
is an early bad system or line and what's not.
Part of what makes the e3 square weak in this system beginning with
1.d4 Nf6 2.f3 is that, in part, the amount of pieces necessary to be
tied up defending it. Only the queen's bishop can defend it after
whites second move. Notice that either black is going to respond
2...e6, 2...g6, or occasionally 2...d6 which lead into very strong
and
orthodox systems that, by themselves maximize the power of black's
bishop pair. When white has a liability from the get go, squares
such
as e3 become weak and prone to assault.
Some tactics from black may include the Q sliding down to h4 for the
simple reason of pulling apart white's Kside supports. With the
Qside
already opened up from move 1, Qside castling will eventually prove
to
be a liability if played.
Much of the time when I've seen 2.f3 at the club level, I've run
something akin to the French or the Bogo or Old Indian against it
with
good success.
The advantage of playing such openings is that they, along with the
King's Indian leave pawn breaks and attacks against white's arsenal
till every piece is pretty much developed and in them no one piece
has
to move more than once or twice to get the opening job done.
Further thoughts from Chris, Jim, Tyson, Paul, Jeff et al correcting
my analysis would be helpful since you guys are a heck of a lot
higher
rated and experienced than the average club level.
BTW: It's really helpful studying games from the IBCA tournaments or
the New in Chess sections in Chess Magazine to see the use and
analysis of various opening theory.

I think I understand most of the below, the f3 square being
taken away from
the Knight, and the d4 pawn being unsupported. But I do not
follow how the
e3 square is weak. The f2 pawn is no longer covering it, but
the Bishop is
still on c1.
Any help appreciated.

David,
Understanding basic positional principals will often guide
you to beat such
stupid systems as 2. F3.
1. D4 Nf6 2. F3?!
Leaves the e3, f2 and other king-side dark-squares weak. The
d4-pawn is not
supported. The f3-square is taken away from the king's white
knight.
So, both 2... d5 controlling the e4-square, preventing e2-e4
and more
importantly,
2... c5 attacking d4 and striking at the dark-squares is
simply equalising
for black.
2... c5 3. Dxc5 e6 and black's already on the road to
controlling the g1-a7
diagonal, where f3 is just a stupid move.
2... c5 3. D5
and black can consider 3... b5 and have an accelerated Benko
or enter into a
Bennoni where f3 is not helpful at all.
One need not learn such theory to such stupid variations.
Understand the
principals and it will turn out just fine for you, if not
equalisation, but
maybe obtaining an advantage.
Cheers,
Chris

Tyson et al,
You're so right! If you go tohttp://www.chessgames.com , ;
there's a great opening
explorer.
.
So when those of us who are not-so-masterly in our experience
see the
line: 1.d4 Nf6 2.f3, it's no time for us to think our
opponent's algebraic
notation is off. It's the pale-face attack and, if you're not
ready for it,
that puppy can be a tough system to navigate.
There are lots of good subvariations with which to respond to
it, though.
