Judit, Alexei, and the Monkey's Bum
I ran across this well-known game while looking into the Modern Defense. Judit Polgar, then 19, defeated Alexei Shirov, then 23, at the 1995 Donner Memorial in Amsterdam. Shirov tried the Modern Defense, and Polgar responded with the Monkey's Bum Deferred. (The Monkey's Bum proper starts 1 e4 g6 2 Bc4 Bg7 3 Qf3.)
Enjoy.
