Be sure to look at Frank Marshall's "Gold Coin" game, and Lasker vs Schlecter World Title Match game ten . At least one person gave three exclamation points too Marshall's winning move. Maybe try key word search " best chess games" or some such key words. The Capablanca vs Marshall game where Marshall tried the Marshall Attack of the Ruy Lopez is a good game. This game shows how great Capablanca's over the board game is.
