Mark half of the shot glasses with the appropriate names of characters (eg bishop etc). Set up the chess board as you would for a regular game. Fill your half of the glasses with something you can down in a shot. Your opponent should fill thiers also. Now you are ready to play. The regular rules apply. The only difference in this game is that when a piece is captured your opponent must drink the liquor from the piece (glass) that was taken. Chess will never be stuffy and boring again, ENJOY!
