=**Anand defeats Kramnik**=


 * Problem:** Black to play and win.

India's Vishwanathan Anand finally resolved all doubts as to his right to be called World Champion with a resounding match victory over his great rival Russian Vladimir Kramnik. Played in Bonn, Germany during October and early November, the 12-game match was virtually decided after Anand won the sixth game to take a 4½ - 1½ lead into the second half. A three-point deficit had never been surmounted in over 100 years of World Championship matches, and so it proved here. Kramnik did recover his strength and put up a fight in the second half, stopping the rot and putting Anand under severe pressure in ninth game, while winning the tenth to prolong the match. However, Anand easily drew the eleventh game to win the match and undisputed title of World Champion with a final score of 6½ - 4½.

The secret to Anand's victory was a daring opening repertoire – deviating from his usual 1 e4 to play 1 d4 as White, which avoided Kramnik's most comfortable defences. But the masterstroke was seeking unbalanced, complicated positions with Black, taking the fight to his opponent even at the risk of a serious opening disadvantage. The strategy worked like a dream, with Anand winning with Black in games three and five in the ultra sharp Meran Variation of the Slav Defence. Today's game is the first of those wins. media type="custom" key="26480592" The Meran Variation, leading to highly tactical play at some risk for Black. Anand's brilliant prepared novelty – sacrificing the b-pawn to accelerate his king-side counter-attack down the g-file. Castling is for wimps! A significant concession on the light-squares but alternatives like 17 Rxd4 Rxg2+! 18 Kxg2 Qxd4 and 17 Bd3 Ne5 18 Be4 d3! show White has no easy answers. Kramnik takes up the challenge and sacrifices a piece to breakthough on d7 with enormous complications. However 19 Rxd4 may have proved sounder e.g. 19 ...0-0-0 (19 ... Bxf3 20 Qxf3 Qxd4 21 Rd1! wins for White) 20 Rad1 Bxf3 21 Qxf3 Qxb5 22 Qxg4 with rook and pawn for two pieces and a much safer king. Anand's //sang froid// in the face of White's attack is breathtaking. Returning the piece to allow his king to reach safety – and incidentally opening the g-file... After this Black's attack just grows in strength, but you can hardly blame White for not finding 27 Rc1 Bg2+ 28 Ke1 Bh3 29 f5! Rg1+ 30 Kd2 Qd4+ 31 Bd3 Qxb2+ 32 Rc2 when Black must take the perpetual check. Redirecting the bishop to strafe the white king from a new diagonal. Allowing an instant win which is the subject of today's diagram. With both players under severe time pressure Black also misses the mating finish in favour of a longer route to victory. Hoping to give up his queen and use the passed pawn to save himself, but it is one tempo too slow... Black catches the pawn after 41...Bb1+ 42 Kb3 Qxf3+ 43 Kb4 Qxf4+ 44 Kc3 Be4 so with the time control reached White resigns. An incredible game.
