{ In our last game, I played like a compete eejit, and lost without a
fight. As I age, I don't mind losing, but I find it embarrassing when I
play badly. } 1. d4 { I have been an e4 player for 30 years, but maybe an old dog can
learn new tricks. } 1... Nf6 2. c4 c5 { Rats. Out of preparation! I had
expected the Tarrasch, the Slav or the Grunfeld. Now, I wondered if he
would play a benoni or a benko gambit. } 3. d5 e5 { The Czech Benoni -
another surprise. I assumed Sam was getting experience playing an unusual
opening, but after the game he said he wanted to avoid my preparation. } 4.
Nc3 d6 5. e4 Be7 { When Alex Baburin first came to Ireland, he gave a
series of lectures to the Dublin Chess Club. One of those was about this
position. What I remember most was the battle to exchange the bad bishops.
White would like to swap the white squared bishops, and black would like to
swap the black squared ones. } 6. Bd3 Nbd7 7. Nge2 g6 { Sam wants to stop
my knight going to f5 via g3. } 8. Bd2 { The idea was to play Qc1 to make
it difficult to swap bishops on g5. Then I would expand on the queenside
with a3, b4 and Rb1 } ({ If } 8. Bh6 Ng4 { forces the bishop to retreat, as
going forward is no good } 9. Bg7 $2 Rg8 { and the bishop is trapped. }) (
8. h4 { is recommended by theory. During the game I worried about him
blocking with 8...h5, and then it may be weak if black moves his Nf6.
However in the games I found, white played f3, and g3, Be3, Qd2, a3, Rb1
and b4. Black's position is very cramped, and he has to be careful not to
open the position. }) 8... O-O 9. Qc2 { Change of plan! I felt if black
plays Ne8 and Bg5, indeed he can swap his bad bishop, but it takes time,
and I can castle queenside, and push my g and h pawns. Also, after playing
g6, without the black squared bishop, his king-side would be quite week. }
9... Nh5 10. g4 $1 Ng7 11. O-O-O { I think it's important to attack,
especially against strong players. It's easier to attack than to defend! }
11... a6 { Ok, it might not be so one-sided as I hoped. } 12. Kb1 $2 { This
is a waste of time, and it allows Sam to play b5 for free. I wanted to keep
the a-pawn protected when the a-file opens. I should have played Rdg1
immediately } 12... b5 $1 13. Qc1 { I decided to gambit my c-pawn. The
queen retreats to let the Bd3 retreat to c2. If black plays bxc4 then that
pawn will block his pieces. } (13. cxb5 $2 Nb6 $1 { and now the threat of
c5-c4 ensures that black wins my g4 pawn. }) 13... Nb6 (13... b4 $2 { is a
strategic mistake. The queenside would be blocked up, with no chance of
attack. } 14. Na4 Nb8 15. Rdg1 Bd7 16. Bc2 { and now Qe8 isn't possible due
to Nb6. }) 14. Rdg1 { The start of the migration of my pieces over to the
kingside. } 14... Nxc4 15. Bh6 Na5 16. Nd1 { The knight is heading for e3
and f5! I want the g-file open, and I don't mind giving up a piece for it.
} 16... c4 17. Bc2 b4 18. h4 { Finally I get my h-pawn going. Earlier I was
afraid Sam would play Bh4 and block the h-pawn advance. However, after Rg2
and then Ng1-f3 would kick the bishop back. } 18... Bd7 19. Ne3 Rc8 $2 {
Sam overlooked the strength of Nf5. He had two reasonable choices. } ({ The
prophylactic } 19... f6 $1 20. Nf5 gxf5 21. gxf5 Rf7 { And white doesn't
have enough compensation for the piece. }) ({ The attacking } 19... b3 20.
axb3 cxb3 21. Bd3 Bb5 $1 { Here I don't want to swap on b5, opening the
a-file. }) 20. Nf5 $1 { Tally ho. It's always nice playing moves like this.

for white. }) 21. gxf5 $1 { I'm not interested in winning the exchange. I
want mate. } 21... b3 22. Bd1 bxa2+ 23. Ka1 $1 { The king will hide behind

the exchange. I'm not interested. } 25... Rxc3 { Ok, that's an offer I
