Magnus Carlsen again increased his lead in the Champions Chess Tour final. In his round five match against Hikaru Nakamura Carlsen demonstrated impressive endgame technique by winning two instructive rook endings which brought him a 2.5-0.5 victory. Wesley So, who can still hope to catch Carlsen, was on the brink of defeat against Anish Giri, when the Dutch number 1 blundered the crucial game away. | Graphics: Champions Chess Tour
