By the time you read this, GM Gawain Jones’ comment “Carlsen draws blood out of stone” would have already gone viral on the Internet. Jones would know. He dared sac his Queen against Magnus Carlsen at the London Chess Classic 2012 a few weeks back! The highlight of Round 8 at the 75th Tata Steel Chess 2013 was Magnus Carlsen’s win against Sergey Karjakin. The critical moment occurred at move 67, when Carlsen decided to force matters with 67.g4!? hxg4 68.h5. Karjakin fell for the bluff with 68…Rh1?, where he could have a draw after 68…gxh5 69.f5 h4 70.f6 Kg6 71.Rxf8 Kf5! and black will force a perpetual check, for example: 72.Rh8 g3 72.Ke1 g3 74.Kf1 Rb1 75.Kg2 Rb2.
