Gelfand won the title by beating Ruslan Ponomariov of Ukraine in a playoff on Monday. The first four games of the playoff were rapid games (25 minutes per player per game) and Gelfand took the lead by winning the second game. But Ponomariov, with his back to the wall, won the last rapid game to tie the match up again. The playoff then went to blitz chess (5 minutes per player per game) and Gelfand once again took the lead by beating Ponomariov in the first game when he managed to trap Ponomariov’s queen in 21 moves. Ponomariov rallied again, winning the second game. But Gelfand won the third and Ponomariov ...

What principles are involved here? You might recall that in the opening game of his defence of the World Title, Capablanca moved the wrong rook, and eventually lost the game, so the decision isn't always easy. However, that particular topic might be better discussed in another thread (but I am aware of wschmidt's point in mentioning it here). To return to the central question, let's take a simple example. In the following diagram, White might decide that it would be a good idea to induce the exchange of knights on d5: w Suppose play goes 1.Nd5 Nxd5. How ought White recapture (2.exd5 or 2.Rxd5)? Well, 2.exd5 does establish a Q-side pawn majority for White, and Black's bishop doesn't look very happy, but Black has now a K-side majority that might become more active than White's on the other wing; and, even more significantly (I feel) Black backward d3-pawn has now been masked from any frontal attack down the d-file. After 2.Rxd5, White will soon double rooks on the file, and can start thinking about conducting a general advance of the Q-side pawns, and/or manouevring his bishop to where it will bring added pressure on Black's d6. Indeed, there is something to be said for moving the bishop before doubling the rooks, e.g. if Black moves a rook to d8 as his second move, say 2...Rfd8 3.Bb6 Rd7 4.Rad1 Rac8 5.c3 or 5.Bc5!?). Suffice to say that the rook recapture seems to offer a more concrete subsequent target for White to aim at, whilst depriving Black of much counterplay beyond some ineffectual swiping down the c-file. The piece recapture on d5 is much more often preferable to a pawn recapture if it means Black is going to be left with a backward pawn on an open file. Just one example among many one might have suggested... Cheers, Ion ——— A tragic knight — The London Chess Classic, a fabulously organized eight-player elite tournament, shaped up as a confrontation between two great chess grandmasters, the top-rated Magnus Carlsen of Norway and the former world chess champion Vladimir Kramnik of Russia. By the luck of draw, they met in the first round, and Carlsen won. The Norwegian GM was still in a clear lead on Sunday with four points in five rounds, a full point ahead of Kramnik. U.S. chess champion Hikaru Nakamura drew four games and lost one. The tournament concludes Tuesday. The Carlsen-Kramnik duel looked like a perfectly played game by the Norwegian, who took advantage of Kramnik's stranded knight. "If one piece is ...

Message: ——— A Game Lasts 163 Moves, and That's Not Even a Record — Chess professionals are conditioned to games that take four to five hours and last about 50 moves, but occasionally play lasts much longer and the contest becomes a war of attrition. That is what happened between Nigel Short and Luke McShane of England in the first round of the London Chess Classic, which started on Tuesday. McShane, who had White, got a tiny advantage out of the opening, but Short defended well, and after 60 moves it seemed as if the game would end in a draw. But McShane, 25, persisted and Short, 44, was forced to continue to defend. It took McShane seven hours, and 163 moves, but he finally broke Short and forced him to resign. That ... |
