It was Kramnik's turn today to miss the winning move and qualification to the final round. He still have a chance tomorrow though in the rapid games tiebreaks. In a 125 move game, Vachier-Lagrave blundered and gave Kramnik a winning position, but then Kramnik missed the winning move in the following position and reached a drawn R+N vs. R ending.
Instead of 62. Ke4, can you find the winning move? Have to warn you, that's a tough sequence of moves!
