India's Viswanathan Anand played out a draw in his fourth and final round game of the 'No Castling' Chess tournament against long-time rival Vladimir Kramnik of Russia to win the Sparkassen Trophy, in Dortmund, on Sunday.
Playing white in a Tarrasch variation, former World champion Anand settled for a draw in 40 moves, to win the match 2.5-1.5.
The Indian maestro won the opening game of the series before the next three ended in draws.
Kramnik, also a former World champion, had forced a draw in the third game on Saturday to keep alive his chances of levelling the scores in the four-game contest.
The event was played as part of the "No-Castling" Chess, devised by the Russian GM.
Castling is not allowed in this format in an effort to make the game more interesting.
Castling is a special move to protect the king and activate the rook. It is the only time in chess a player can move two pieces in one move.
Anand had returned to over the board action at the Croatia Grand Chess Tour tournament in Zagreb last week and took overall second place (Rapid and Blitz sections combined).
