Stories have a way of writing themselves. As an example, I give you two games from the 7th round, Gelfand-Kramnik and Carlsen-Radjabov.
I’ll start with the Gelfand-Kramnik game. Here’s the position after Kramnik’s 18…Nf6-e8.
rq2n1k1/1b3ppp/pp1bp3/8/3PN3/3B1NP1/PP2QP1P/2R3K1 w - - 0 19)
ChessVibes’s writeup has the following: “For a moment Kramnik was in big trouble, but he escaped with a draw when his opponent Boris Gelfand of Israel refrained from playing actively on move 19.”
That’s true – White can win with the very nice 19.Neg5! g6 20.Nxf7! Kxf7 21.Ng5+ Kf6 22.Qxe6+ Kxg5 23.Qh3!! (the only move to win). Of course, White’s work is not yet done, for example 23…Kf6 24.Qxh7 Bb4 (covering e1, freeing the Qb8 to come into the game), he should find 25.Rc2!, winning.
