Anand returned to the Gruenfeld defence in Game 10: the result is 5:5
The 10th game FIDE World Chess Championship saw a return to the Gruenfeld Indian defence, which Viswanathan Anand temporarily archived after the defeat in the first game of the match.
This time he chose a different continuation and played 10...b6 instead of Na5.
After the full pieces' development of both sides, Topalov advanced his d-pawn to the 5th rank, which prompted a double Rook exchange on the c-file.
Black obtained good play with timely pawn advances, e6 and f5.
Later, Anand surrendered Bishop's pair in order to trade the Queens and head into an endgame where Topalov once again held a passed d-pawn. However, Black had it firmly blocked and the play revolved around the neighboring diagonals.
Topalov could not make progress and Anand started rolling his own pawn majority on the queenside. After numerous pawn exchanges, the game evaporated into a draw, which was signed on move 60.
Saturday is rest day, the next game is taking place on Sunday, 15:00 local time.
