Dec-19-07		russep: Is this rapid chess or are these games at classical time control cause it looks like Dreev gave his queen away for Svidler's Rook

Dec-19-07		tamar: <russep> Black's queen has to go, or Rg5+ is coming click for larger view The time limit is described by Chessbase as a mix of classical and FIDE controls- "1hr 40 mins for the first 40 moves, then 50 minutes added for the next 20 moves, and 10 minutes more to finish, PLUS a 30 second increment from move 1."

Dec-19-07		supertimchan: Peter played very well.

Dec-19-07		MarvinTsai: Dreev may be in serious time trouble since he overlook 28.Rxh6 sac. I like black's position after 26.Qxe5. b4 threat looks more dangerous than g5.

Dec-20-07		Mateo: A very lively game. Dreev lost his way when he played 27...Qc5?, allowing the forced variation 28.Rxh6! gxh6 29.Qxh6 Qe5 30.Rh5. Now, Black has to return material. 30...Qf6 31.Rg5+. How? If 30...Qxh5 31.gxh5 Bxf3 32.Nd4 Bd5. Black has Rook+Bishop+pawn vs Queen, wich is consiered as balanced material. But after careful examination, White has a much better position after 33.b4 (defending against the threat of mate). For instance, 33...Rc4 34.Qg5+ Kf8 35.h6! wins. 33...e5 34.Nf5 wins. 33...Rc3 34.Qg5+ Kf8 35.Qd8+. It's hard to see what Black can do, meanwhile White has many promising ideas.

Dec-20-07		Mateo: 32.Nf4! threatening Nh5 was a killer. In the final position, Black has to give up the Rook to avoid mate.

A confident comeback from yesterday’s disaster His sacrificed pawn gave Svidler some good attacking opportunities down the ‘h’ file which finally won him the game. That was what you should expect from sacrificing a pawn. Not like yesterday when Svidlers loss of a pawn turned in to a disaster..

Dec-20-07		AdrianP: Svidler has very much had Dreev's number, especially with the white pieces - http://www.chessgames.com/perl/ches... +5 -1 =1 (and the loss was in 1993 when Svidler would have been under 20?).

Dec-20-07		AdrianP: Make that +6 -1 =1 including this game.

Dec-21-07		al wazir: This game has good examples of a sacrificial attack that failed (black's 23...Rxc2) and one that succeeded (white's 28. Rxh6). My guess is that on average, half of all such attacks fail. The other half turn up eventually as <CG> puzzles.

Dec-21-07		Eyal: Position after 26.Qxe5: click for larger view Here 26...Nd7(?) helps White, because it removes the knight to an inferior quare and forces White into making a good attacking move, 27.Qe3. Instead, Dreev could have justified his previous play by continuing the attack with 26...b4! (mentioned by <MarvinTsai> above) and Black has the upper hand: 27.g5 Nd7 (now it's much better) 28.Qe3 bxa3 29.Qxa3 (29.bxa3 loses immediately to 29...Bd5 30.Nc1 Rb8) 29...Qxe2 30.gxh6 g6; or 28.Qh2 bxa3 29.bxa3 Qc5 (29...Bd5? 30.Nf4). 27.axb4 Qa4+ 28.Kb1 Nd5 29.g5 (or 29.Rc1 Rxc1+ 30.Nxc1 Nxb4) 29...Qc2+ 30.Ka1 Nxb4 31.Nc3 Qxb2+! 32.Kxb2 Nd3+ 33.Kc2 Nxe5 34.gxh6 Nxf3 35.hxg7 Rc7! 27.Rc1 Qd3 28.Rxc8+ (28.axb4 Nxg4!) 28...Bxc8 29.Qc7 Bd7 30.Nc1 Qf1; or 29.Qc5 Bb7 30.Nc1 Qf1.

Dec-22-07		Ulhumbrus: 16 a3? disturbs the Q side pawns, but then 16...Bxg5? opens the h file for White.
