Grandmaster Michael Adams of England survived some anxious moments in a game of fluctuating fortunes before finally settling for draw with GM Rustam Kasimdzhanov of Uzbekistan in the sixth game of the World chess championship final, now in progress in Tripoli, Libya, on Tuesday.

The draw ensured that the highly entertaining contest between the two Grandmasters stayed level at 3-3 after the completion of the scheduled six games and will be stretched to the tie-break stage, wherein games of shorter duration will be played to determine the winner.

Even as many expected a draw to be a just result in the last game under normal time control, Adams knew he had survived by the skin of his teeth as the drama ended with the Englishman threatening to give perpetual checks to keep himself alive and kicking in the match.

Adams himself missed a winning opportunity in the closing stages of the game before signing the truce after 44 moves.

It may be recalled that between the sandwich of two draws in the first and sixth game, there were four decisive games in which the white player won. And the level scores are a perfect indication of the close contest in the final that many believed would be a cakewalk for second seed Adams, ranked sixth in the world.

Determined to score a decisive victory with white pieces, Kasimdzhanov went for a dangerous variation in the Ruy Lopez and was looking in command when the middle game surfaced.

However, Adams neutralised white's advantage with a timely pawn sacrifice that forced white's king in the open. After a temporary piece sacrifice in the queen and minor piece ending, Adams secured the draw with correct play clearly overlooking a promising continuation on the 42nd move that would have yielded him the champion's crown.

Now that the match is dragged to its final leg, Kasimdzhanov is certainly the favourite with his excellent track record in the rapid version of the game.

The Uzbek has already beaten top seed Veselin Topalov of Bulgaria, third seed Alexander Grishchuk of Russia and fourth seed Vassily Ivanchuk of Ukraine in the first set of tie-break games earlier in the championship.

On the other hand, Adams comes to the tiebreaker with virtually no practice at all as none of his opponents could force him to a deadlock under normal time control.

The winner of the match gets a purse of US $1,00,000 while the loser has to be satisfied with US $70,000.
