A short but powerful tournament has just begun in Madrid that includes three players from the world's top dozen. The favourite is Viswanathan Anand, whose strongest competition may be expected to come from Peter Svidler of Russia, and England's Michael Adams.

Anand has begun in powerful style with a win against Adams in the opening round. Playing 4...Ba6 and 5...Bb7, Adams sacrificed a move in order to make c3 a less secure square for the white knight. His strategy continued with 6...Bb4+ and 11...Bxc3, leaving White with the bishop pair, but hoping to show that the black-squared bishop was not as useful a piece as a black knight.

When White played 14.Bc1, it looked as though Black had proved his point, but White still had more space and a natural space-gaining plan of b5, Ba3 and an eventual c5.

Adams's 14...b5?! was a bold bid to seize the initiative by taking a grip on the central white squares at the cost of a pawn. If all goes well for Black, he will eventually regain the pawn on b5, with the prospect of reaching an endgame with a good knight on d5 or c4 dominating an ineffective white bishop.

But all did not go well for Adams. The ugly 16.Ba3 proved an effective way of keeping both white b-pawns defended, leaving Anand free to get on with an advance in the centre. Black's attempts to build up an attack on the K-side were never allowed to become threatening. White increased his advantage with 36.Nf6+! and 38...Ne3? only hastened the end.
