World No. 1 Magnus Carlsen has begun the Bilbao half of the Sao Paulo-Chess Masters final with a win over leader Fabiano Caruana. The game lasted more than four hours. The Norwegian held his own in the French defense game and entered the middle game with a slight advantage, which after a simplification of some pieces, ended up in a hard-fought but equal endgame. But, Caruana committed inaccuracies. (The round report is available at Chess Blog.) Run the Chess King applet to enjoy the game.
