World champion Viswanathan Anand missed out on a winning advantage and played out a draw with Daniel Fridman of Germany in the fourth round of the Grenke Chess Classic in Baden-Baden, Germany.
With his fourth draw in as many games, Anand slipped to joint third spot in the six-players double round-robin tournament.
Italian Fabiano Caruana played yet another fine game to draw as black against Michael Adams of England while in the other game of the day, Arkadij Naiditsch of Germany accounted for compatriot Georg Meier.
With six rounds still to come in the category-19 event, Caruana stayed on top with three points out of a possible four and Naiditsch jumped to second spot a half point behind. Fridman on two points shares the third spot with Anand while Adams is now on fifth spot on 1.5 points. Meier with one point in his kitty stands last.
What could have been a finely crafted victory turned in to a missed chance for Anand. The Indian ace went for a topical variation as black and came up with an improvement in the opening to equalize easily as black.
Fridman hung on to his own to get to a slightly worse endgame wherein the grind began to favour Anand once the position boiled down to pure minor piece endgame.
It was only on the 48th move that Anand faltered decisively. Instead of a Bishop retreat, the Indian went for a wrong manoeuvre after which Fridman gave no chances. A draw was signed ten moves later.
Naiditsch came up with his third decisive games out of four rounds and cruised to his second win. The Slav defense was Meier did not prove good enough as imaginative display by Naiditsch helped him reach a decent advantage in the middle game.
Meier was down to his last minute when he failed to spot a single chance that came in his way and it was all over pretty soon.
Caruana opted for the sharp Arkhengelsk variation against black and appeared to be in some difficulties in the ensuing endgame.
However, an erroneous plan by Adams led to an easy equality and the draw was a just result. The game lasted 50 moves.
Results round 4: Daniel Fridman (Ger, 2) drew with V Anand (Ind, 2); Michael Adams (Eng, 1.5) drew with Fabiano Caruana (Ita, 3); Arkadij Naiditsch (Ger, 2.5) beat Georg Meier (Ger, 1).
