Vishwanathan Anand drew his fourth round game against Braingames champion Vladimir Kramnik of Russia to remain in the joint second position in the 20th Linares Super Grandmasters chess tournament.

With half a point from the board, Kramnik, who has so far played a game more than the Indian, maintained his position at the top of the table with 2.5 points. Anand was placed second alongwith Hungarian Grandmaster Peter Leko, both having had a bye each in the tournament already. The duo have two points from three matches.

Teimour Radjabov of Azerbaijan was also placed second though he has played one board more.

Kramnik, however, could lose the sole lead in the next round when he takes his first of the two allotted byes.

After an excellent first round win over world champion Ruslan Ponomariov and an easy draw with black against Spaniard Francisco Vallejo Pons in the second, Anand, with white pieces, was expected to try harder against Kramnik in the fourth round.

However, he disappointed his fans by opting for a surprise opening -- the Rossolimo attack -- as Kramnik had proved devastating in the same variation against Ponomariov in the second round game.

Anand tried a new idea after dismantling black's pawn structure a little but an alert Kramnik went for the trade of queens that guaranteed a level endgame. The draw was agreed to after just 16 moves.

Vallejo Pons played out his third draw in as many games when he held Radjabov with white. 

Vallejo, who faced the McCutcheon French, went for a direct attack against the king with a couple of pawn sacrifices in the middle game but Radjabov thwarted all his threats with ease.

After sacrificing a pawn, Radjabov secured a dynamic balance but decided against pressing hard in rather double-edged position. The peace was signed after 48 moves.

Peter Leko troubled Ponomariov a lot in another Rossolimo attack game of the day but could not derive the maximum from an advantageous endgame with black pieces.

Leko played the opening in an inspiring fashion and won a pawn on the 36th move with perfect moves at the center.

Though at the final stages of the game Leko managed the position he was looking for with very little time remaining on his clock, he could not strike upon the best manoeuvres to eventually part with half a point after 110 moves.

The world's highest rated player Garry Kasparov had a bye in this round and will resume with white pieces in the next board against Ponomariov tomorrow after the rest day today.
