Game 3:  Dreev vs. Kotronias

0.
@Q0
[Introduction: The site is Las Vegas, gambling Mecca of the USA. The event is the F.I.D.E. World Championship Tournament, a knockout event where only the winners of short matches advance. It's the off season, July and August 1999, and the who's who of the chess world are in attendance. Only the World Champion himself, Gary Kasparov, is missing, but this only makes it easier for someone else to win. 

Your partner for Game #3 is the Russian Grandmaster Alexey Dreev and you have the White pieces. Your opponent is the talented Greek GM, Vassillios Kotronias. Both Dreev and Kotronias have toppled their first-round opponents and find themselves paired for round number two. 

It's game one of the match and Dreev wants to make good use of the White pieces. A win in game one with White, a draw in game two with Black, enables Dreev to advance while Kotronias goes packing. This in fact is just what happens. Dreev advanced to round three defeating the Dutchman Jan Timman, but was himself knocked out in round four by British superstar Mickey Adams. 

Adams got by another superstar, V. Kramnik, in round five, but lost to the unheralded V. Akopian in round six. Round seven was the finals with another unheralded, but not unknown player, Alexander Khalifman of Russia. He defeated Akopian to win the "Championship." So, at least for Khalifman, Las Vegas was the place where dreams can come true.]

If Black gets back his pawn by 20...Bxc3, 21. bxc3 Qxc3, which squares around his castled position become weak?;
f6 and h6:This is the correct answer. These squares can no longer be guarded by a pawn, so they require the dark-square bishop's protection.:1;
g6 and h6:Incorrect. The square h6 is weakened by the bishop's disappearance, but g6 is still protected by the f7-pawn.  It is not directly affected by the dark-square bishop's absence.:0}]

@Q58
[Conclusion: The opening starts out looking as though it will be a Sämisch King's Indian, but at move six (6...c5), Kotronias switches to a Modern Benoni formation. In the resulting position White's imposing pawn center is rather immobile, but at the same time it is also very solid. This prompts Kotronias to seek his play on the flanks and the question is whether Dreev can fend him off. 

After a bit of hesitation (16. Rac1), Dreev finds the right place for his Rook, 18. Ra1, and the critical infighting takes place over the next four moves. The key idea is to return the dark-square bishop to the queenside, 21. h4 gxh4 22. Bd2. This sends the Black queen into retreat and the Kotronias flank attack is essentially over. 

Move by move Dreev begins to improve his position, mostly by the simple expedient of exchanging off Black's active pieces: first the dark-square bishops and then the queens (moves 25 thru 29). He knows that if he can reach an endgame, Black's doubled h-pawns are sure to fall. 

An exchange of all four Rooks on the c-file (moves 37 thru 39) reduces counterplay to nil. That done, an ending is reached where the White center pawns begin to assert themselves (40. f4 and 41. e5), cramping Black even further. There follows an exchange of bishops (moves 42 & 43) after which the White king has clear access to the h-pawns. As predicted, the h-pawns fall and White enjoys both material and positional advantage in the knight-and-pawn ending. 

To complete the encirclement Dreev shifts his king from kingside to queenside, and at the very end, there is no way to keep the White king from gobbling up Black's remaining pawns on the a & b -files. In short, a complete performance by Dreev, using all three sectors of the board, and all three phases of the game, just like a three movement symphony.]
