Catalan Nine Tails
This is a really interesting game. It was the fourth game of the World Chess Championship that took place earlier this year. Up until this point, the scores were even and the tension was at its highest. Anand needed a win, and he got it in style. On the 23rd move, he sacrifices a piece in order to smash through Topalov's kingside, and the rest is a matter of mopping up.
