Chess

Chess is the most beautiful game in history. All aspects of human intelligence are found over the board. Memory, creativity, tactics, psychology... Like you can go 50 moves deep into an opening, or just blow it on the first five turns, and do some amazing sacrifice, or set up a tactical position that forces your opponent to do something in three turns. It's a brilliant game. And being only 64 squares, and completely visible--both players have complete information--it's truly a meeting of minds.
