Happy Pi Day! I just recently celebrated my 17th birthday...boy, do I feel old.
Anyway, to celebrate, here's a matchup between Alekhine and the little-known Maurice Fox. On the 17th move, Alekhine decides to sacrifice the exchange to get an attack. The rest of the game is utter chaos, with both players sacrificing, Alekhine to win the game, and Fox to hold on and defend.
