Chess champion Magnus Carlsen tried a new opening with White Tuesday, but the result was the same: yet another draw in Game 4 of his title defense against Russian challenger Ian Nepomniachtchi.
The draw leaves their scheduled 14-game match in Dubai knotted at 2-2.
The Norwegian champion opened with 1. e4 Tuesday, after experiencing some opening discomfort with a Closed Catalan in Game 2. Nepomiachtchi appeared to surprise the champ with a Petroff’s Defense (2…Nf6), an opening he had never played before. White stuck with the main theoretical lines and obtained some mild pressure entering the middlegame — while using far more time on his clock than the Russian.
But an early queen trade left White struggling to generate chances, even after Carlsen was able to trade bishops and get a rook and a knight planted deep in his opponent’s position.
A passed a-pawn gave Black plenty of compensation, and in the end, a frustrated White settled for repeated checks against Black’s boxed-in king, leading to a draw after 36 moves.
Nepomniachtchi will again have the advantage of the White pieces in Wednesday’s Game 5 before the second rest day of the match. The first player to score 7½ points wins, with a one-day rapid and blitz playoff set for Dec. 16 if the players remain tied.
