Viswanathan Anand scored a thumping victory against Peter Leko of Hungary and caught Peter Svidler of Russia on second spot after the 12th round in the World Chess Championship San Luis, Argentina.
The second victory on the trot also helped Anand move closer to championship leader Veselin Topalov of Bulgaria after the latter took a quick draw as white against Svidler.
The other two games of the day also ended in draws with Michael Adams of England signing peace with Rustam Kasimdzhanov of Uzbekisan and Russian Alexander Morozevich failing to breach the solid defenses of Hungarian Judit Polgar.
With only two rounds remaining after the final rest day today in the one million dollar event, it appears that Topalov (9 points) has decided to take things easy. The Bulgarian is now just two draws away from the World championship title.
Anand and Svidler are tied second at this stage with 7.5 points apiece and the race for the second spot is likely to heat up in the remaining rounds.
A very distant fourth is Alexander Morozevich who is on 6 points and Leko and Kasimdzhanov hold the fifth spot together on 5 points apiece. Adams is next in line on 4.5 while Polgar is at the bottom of the list with 3.5 points.
Theoretically, Anand can still catch up with Topalov but for that the Bulgarian must lose at least one of the last two games and draw the other while Anand will have to beat Morozevich and Svidler in the last two rounds.
World champion this time or not, Anand was in top form against Leko.
The Hungarian is in dire straits here and obviously wanted to use his white pieces for the good but as the event unfolded he was left completely dejected.
Anand chose the Petroff defense, an opening known to give the black player a level position with deep preparation. Leko perhaps sensed that it was coming but his choice of complications led to disaster.
Once into the middle game with Leko's King appearing weaker than Anand, the Indian ace concentrated his efforts on the queen side and swept a couple of pawns.
Leko did not get any real counter play anywhere on the board and after the trading of queens it was a cakewalk. The Hungarian resisted for sometime but was forced to call it a day when checkmate became imminent. The game lasted 53 moves giving Anand his second victory as black in the event after he beat Polgar in round one with the slightly unfavourable colour.
Topalov played it safe and fine against Svidler who could do little with his black pieces. Having done the hard work earlier, the Bulgarian was certainly content to do just the needful in the remaining rounds.
It was an Anti Marshall where Topalov had a slightly better prospect when he just proposed the truce Svidler could not refuse.
The shortest game of the day lasted just 21 moves.
Morozevich showed his keenness to an intense battle and surprised everyone by going for the Van Geet opening on the first move against Polgar.
However just a few moves later the players found themselves in a Sicilian Nazdorf vide transposition and even though Morozevich stood better for the major part of the game, Polgar was intent enough to not let the game go completely out of hand.
Routine exchanges led to a pawn less endgame for Morozevich but by then Polgar had control of the seventh rank, which was enough to steer the game to a draw after 54 moves.
Kasimdzhanov, white, also troubled Adams a great deal before the draw in another Anti Marshall of the day. The Uzbek, who started here as the defending champion, had an extra pawn in the queen and minor piece endgame but Adams' counter play was quite significant. The draw was agreed to after 44 moves.
