Sergey Ivanov: } 1. e4 d6 2. d4 Nf6 3. Nc3 g6 4. Be3 Bg7 5. Qd2 c6 6. f3 b5 { The first moves have defined plans of both players. White is ready to
carry on his play at the kingside and in the center, and Black - on the
queenside. } 7. Nge2 Nbd7 8. Bh6 { Standart action for such a position. Now,
if Black performs kingside castling, White exchanges dark-square Bishops and
attacks with his pawns - g4, h4 etc. Black King becomes uncomfortable. } 8... Bxh6 9. Qxh6 Bb7 { Black prepares to evacuate his King to the opposite side. } 10. a3 { Prophylactic! } ( { In the case of } 10. O-O-O b4 11. Nb1 Qa5 { Black would have counter-play. } ) 10... e5 11. O-O-O Qe7 12. Kb1 { An important
feature. Russians say not without reason, that "long" castling is long not
only for that reason that the rook makes a long transit, but also because it
must be "completed" with the move Kb1. Besides of this useful prophylactic,
White plans (expecting queenside black castling) to transfer his Knight via a
route Ne2-c1-b3 to the a5-square. From here it will exert pressure on the
Black's queenside, weakened by pawn moves. However, this plan looks somewhat
slow, and Black has time for counter-chances. } 12... a6 13. Nc1 O-O-O 14. Nb3 exd4 15. Rxd4 c5 16. Rd1 Nb6 { Black is ready to open play in the center
with d6-d5 and to take the initiative. } 17. g3 { White need to finish development of his kingside as soon as possible. } 17... Kb8 18. Na5 Ba8 19. Bh3 d5 { Players' strategic plans are over. White has
set "bridge-head" (Knight a5!) to attack the bared black King, Black has
carried out a pawn blow in the center. Now concrete tactical play begins. } 20. Qf4+ Ka7 21. Rhe1 d4 ( { After } 21... dxe4 { an even position would have appeared, but Topalov wanted more. } ) 22. Nd5 $6 { Of course, the Knight's retreat would be a refutation of White's strategic
line. Kasparov has noticed, that there are too many weak points around the
black King, producing ideas for various tactical operations. } 22... Nbxd5 $5 ( { Lost is } 22... Bxd5 $2 23. exd5 Qd6 24. Nc6+ Ka8 25. Re7 $18 ) ( { or } 22... Nfxd5 $2 23. exd5 { Black Queen is OVERWORKED - it couldn't defend the points
