{A22: English Opening: 1...e5 2 Nc3 Nf6} 1. c4 e5 2. Nc3 d6 3. Nf3 Nf6 4. g3
Nbd7 5. Bg2 c6 6. O-O Be7 7. d3 O-O 8. Rb1 a5 9. a3 Re8 {Black has pursued an
Old Indian-type setup in the opening, which is a little passive - especially
in the placement of the dark-square bishop - but solid. White continues with
the standard plan of queenside expansion.} 10. b4 axb4 11. axb4 Nf8 12. b5 c5
$146 {this is a significant strategic error, essentially giving up d5 and the
long diagonal without a fight.} (12... Qc7 13. Qb3 Bd7 14. Ba3 Ng6 15. d4 Bf8
16. d5 c5 17. e4 Rab8 18. h3 h6 19. Kh2 Nh7 20. Bb2 Be7 21. Ra1 {1/2-1/2 (21)
Smagalski,S (2042)-Milanowski,J (2131) Polanica Zdroj 2004}) (12... h6 $11) 13.
Bg5 $14 {my idea was to eliminate Black's remaining defender of d5.} h6 14.
Bxf6 Bxf6 {Black has the pair of bishops, notes Houdini via the Fritz
interface, but the dark-square bishop is "bad" and the light-square one is
doing nothing currently.} 15. Nd5 (15. Nd2 {would have been a useful
preparatory move here, unleashing the Bg2 and preventing Black from developing
the Bc8.}) 15... Be6 16. Nd2 Bg5 17. h4 {I chose the more aggressive move here,
which however is inferior to the blocking move e3.} (17. e3 {and now the
dark-square bishop is even more limited. The move also prevents a trade of the
bad bishop for the Nd2, which has strong potential in this position.}) 17...
Be7 $6 {my opponent should have seized the opportunity for the piece exchange.}
(17... Bxd2 18. Qxd2 Nd7 19. Ra1 Bxd5 20. Bxd5 $14) 18. Ra1 {the obvious
method of continuing on the queenside, but b6 should also be considered.} (18.
b6 Bxd5 19. Bxd5 Rb8 20. Ne4 $16) 18... Rxa1 19. Qxa1 Qb8 (19... Bxh4 $5 {
the engine considers this diversionary sacrifice slightly preferable. It would
certainly generate more activity for Black, whose pieces are largely on the
sidelines. One possible continuation:} 20. gxh4 Ng6 21. Ne3 Qxh4 22. Re1 $16)
20. Nxe7+ $6 {this betrays my lack of positional understanding, specifically
of the relative value of the minor pieces. White essentially starts to
liquidate his own advantage.} (20. b6 $5 Bd8 21. Qa7 $16) (20. Qa2 {would also
be a good plan, with the idea of Ra1 to follow.}) 20... Rxe7 $14 21. Qa5 $6 {
this was simply dumb, allowing Black a tempo to chase the queen and also
giving up the a-file. The plan with Qa2 (or Qa3) would be better.} b6 $11 22.
Qc3 Ra7 23. Ra1 Rxa1+ {Black need not have been in a rush to exchange, a
typical Class player reaction. Maintaining the tension would have been better
for control of the a-file.} (23... f5 $5) 24. Qxa1 {White now has a small
positional advantage.} Nh7 $6 {poor placement for the knight.} (24... Bg4 25.
Kf1 Ne6 26. Qa8 Qxa8 27. Bxa8 $14) 25. Qa8 {this move heads for an obvious
draw, although Black played on for a while after the exchange. I was not
sophisticated enough to spot an alternative.} (25. Nb1 $5 {is what the engine
finds, getting the knight into play effectively. For example} Nf6 26. Nc3 Kf8
27. Qa6 Bc8 28. Qa8 Qxa8 29. Bxa8 Be6 30. Na4 $16) 25... Qxa8 $11 26. Bxa8 Kf8
27. Nf1 Ke7 28. Ne3 Kd8 29. Bd5 Nf6 30. Bg2 Ke7 31. Kh2 Kd8 32. Bh3 Ke7 33.
Bxe6 1/2-1/2
