Here's an amazing finish from the Tata Steel Wijk aan Zee tournament, round 9, 24 January 2012. If you cut to move 47, you will see that Anish Giri (Black) is under pressure in the key position. But he then allows the exchange to a king and pawn endgame. Always a risky decision, of course, but at first it looks like he can hold. However, it turns out to be a blunder as Vasily Ivanchuk finds a very precise line to force a win. Very instructive!
