1. d4 Nf6 2. c4 g6 3. Nc3 Bg7 4. e4 d6 5. h3 O-O 6. Be3 $5 {An interesting
move idealized by David Bronstein in 1953, and played recently in the active
chess match Karpov-Morovic, October 2005.} c5 7. dxc5 Qa5 {
This is Black's best reply.} 8. Bd3 dxc5 9. e5 Nfd7 10. f4 {Here we see
White's idea: get a spatial advantage in the center, and paralyze the line of
action of the bishop on g7} Rd8 11. Nf3 $1 ({Another possibility was} 11. Qe2
Nc6 12. Nf3 Nd4 $1 13. Nxd4 Nxe5 $1 14. fxe5 cxd4 15. Bd2 dxc3 16. Bxc3 Qb6 {
and Black has no problems.}) 11... Nxe5 12. Nxe5 Bxe5 13. fxe5 Bf5 14. e6 {
This move was found after long hours of analysis and causes serious problems
even for my opponent Rybka.} ({
In the game Romero Holmes - Juseinov, White played the looser} 14. O-O $2 {
and after} Rxd3 15. Qe2 Rxc3 16. bxc3 Be6 $1 {Black gained the initiative.})
14... fxe6 ({Another move for the studious is} 14... f6) 15. O-O Bxd3 16. Qf3
$1 Nc6 ({If} 16... Bxf1 17. Rxf1 Nc6 18. Qf7+ Kh8 19. Bh6 Rg8 20. Ne4 {
followed by mate in a few moves.}) 17. Bh6 ({
During the game, I wasn't sure whether to continue the attack with} 17. Qf7+
Kh8 18. Bh6 Rg8 19. Rad1 $1 Bf5 $1 (19... Bxf1 {fails once more to} 20. Ne4 {
followed by an inevitable mate.}) {and now the spectacular} 20. Nb5 $1 g5 $3 {
the only move} ({the natural} 20... Rad8 {fails to} 21. Nxa7 $3 Rxd1 22. Rxd1
Qxa7 23. Rd8 Nxd8 24. Qxe7 {followed by mate.}) 21. Nd6 {
threatening 22.Qf6!! exf6 23.Nf7#} Qc7 $3 22. Nxf5 exf5 23. Rxf5 Nd4 $1 24.
Rxg5 Rxg5 25. Bxg5 Ne2+ 26. Kh1 Ng3+ {with a perpetual check.}) {
Nevertheless I played more ambitiously} 17... Bf5 $1 {
A tough psychological blow since I had only expected} (17... Kh8 {after which}
18. Rad1 $1 Bc2 {only move} 19. Qf7 Rg8 {and now the demolishing shot} 20. Rd6
$3 {wins in all variations.}) 18. g4 Rd3 19. Qg2 Qc7 20. Bf4 $1 {
I spent nearly all my time on this move since the alternatives} (20. Kh1 Qg3 $1
) ({as well as} 20. Ne2 Qd7 21. gxf5 exf5 {don't seem very convincing for
White, especially playing a fast time control against the computer.}) {
Though I played 20.Bf4 instinctively, it turned out to be best.} 20... e5 21.
Nd5 Qd6 22. Bh6 Nd4 ({If} 22... Be6 23. Rf2 Bxd5 24. cxd5 {followed by 25.Raf1
and Black would be fighting for the draw since the threats on the 7th and 8th
ranks amply compensate for the loss of material.}) 23. Rae1 $1 ({Better than}
23. gxf5 Rg3 24. Qxg3 Ne2+ {with an unclear position.}) 23... Be6 24. Nf6+ $1 {
Unfortunately, I only found this tactical maneuver as I was about to lose on
time.} Kh8 ({Bad would be} 24... exf6 25. Qxb7 {with a winning double attack.})
25. Ne4 Qc6 26. Qh2 Qc7 27. Ng5 $3 Bg8 $1 (27... Bxc4 {would lose due to} 28.
Qf2 Qb8 29. Qh4 Qg8 30. Rxe5 {with a decisive attack for White.}) 28. b3 (28.
Qxe5+ {would also give a clear advantage} Qxe5 29. Rxe5 Nc6 {only move} 30.
Rxc5 {however my 30 seconds on the clock didn't let me think.}) 28... b6 29.
Rxe5 $2 {this mistake due to time trouble throws away the game. Instead:} ({
after} 29. Qf2 $1 {
Black, with difficulty, could have managed to draw according to Rybka with} e4
$1 {only move} 30. Rxe4 Re8 31. Nf7+ Bxf7 32. Bg7+ Kxg7 33. Qxf7+ Kh6 34. g5+
Kxg5 35. Rg4+ Kh6 36. Rh4+ Kg5 {and draw.}) ({Also worth considering was} 29.
Qxe5+ Qxe5 30. Rxe5 {with a certain White advantage. This was what I wanted to
play with seconds on the clock yet my hand went for the rook!...}) 29... Rg3+ {
a decisive intermediary move (zwischenzug).} 30. Kf2 Rc3 31. Kg1 Rc2 32. Qh1
Rd8 (32... Qxe5 33. Nf7+ Bxf7 34. Qxa8+ Bg8 35. Qxg8+ Kxg8 36. Rf8#) 33. Rfe1
Ne2+ 0-1
