 Anand wins in round 11. Adams pressed against Topalov but didn't break through, and the game was drawn. Photo © http://www.wccsanluis.net Round 11 10th October 2005 A highly important round for the fate of the title. Michael Adams played a strong opening novelty in a Sicilain Scheveningen to put Vesselin Topalov under real pressure. Adams' attack netted him an exchange for a pawn but calm play from Topalov meant that he never looked like increasing his advantage. Eventually he bailed out into a perpetual check. The game was important because Topalov's closest rival Peter Svidler defeated Alexander Morozevich. The opening was a Petroff Defence and as usual white got nothing, this opening is virtually killing 1.e4 as a winning weapon at the highest level, white instead just has to settle for variations with plenty of pieces on the board but level play. Here its not quite clear where Morozevich went wrong but his position gradually slipped to inferior, then poor. The ending was clearly in Svidler's favour but he nearly threw away the advantage through not being able to decide how to proceed. In the end he found the right idea and was winning when Morozevich played a trap that wasn't a trap and lost a bishop. Svidler has black against Topalov in round 12. If Topalov had lost Svidler would have been a point behind and probably would have found it worthwhile to risk all in a title or bust attempt, a point and a half makes this gamble slightly less worthwhile as I'm sure second place will carry with it important privalages in the next cycle. Viswanathan Anand demolished Rustam Kasimdzhanov in a Sicilain Najdorf where a couple of bad moves left white totally winning by move 19 and ten moves later he had to resign. Judit Polgar against Peter Leko barely counts as a game. Both probably just want the tournament to end. They followed the game Ionescu, Co - Mateuta, G 1/2 TCh-ROM A (9) Tusnad ROM 2005 until move 24 (the end of that game) Polgar played 25. Red1 and they agreed a draw.
