They also hire trainers, who are called seconds, to help. It is a time- and labor-intensive process. That is one of the reasons that fans look forward to the chess matches. They want to see what the players will do and what new ideas they have discovered, particularly in the openings. The current world chess championship match between Viswanathan Anand of India, the titleholder, and Veselin Topalov of Bulgaria has been as closely contested as predicted. But there have been no eye-opening innovations. Game ...

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 ——— With Another Draw, Chess Championship Match Remains Tied — Game 10 of the world chess championship match between Viswanathan Anand of India, the titleholder, and Veselin Topalov of Bulgaria, ended in a relatively uneventful draw on Friday. With only two games remaining in the best-of-12 series, the players are tied with 5 points apiece. If the match should remain tied after the last two games — which is a real possibility at the moment — it would go to a tie-breaker of four rapid games (each player starts with 25 minutes and has 10 seconds added to his time after each move). Such a tie-breaker was used in the 2006 world chess championship match between Topalov and Vladimir Kramnik of Russia. After each player won a game, and one ended ...

Message: ——— Title Match Remains Tied After Champion Misses Win — With the world chess championship match having entered a critical stage, Viswanathan Anand of India, the titleholder, switched openings in Game 9, hoping to recapture momentum and the lead that he relinquished with a loss in Game 8. He almost did. But, with victory in sight, Anand faltered and missed a couple of winning continuations, which allowed Veselin Topalov of Bulgaria, the challenger, to salvage the game and keep the best-of-12 match tied. In each of the previous games he had White, Anand had steered the opening into the Catalan system, which is solid, but not too dynamic. In Game 9, he played 3 Nc3 instead of 3 Nf3 for the first time. That gave Topalov ... |
