Play Sit & Go at the maximum allowable entry fee with two players, no limit, and the game of your choice at the novice level. Go all in as soon as you have even a marginal hand. Your opponent will do the same if you go in with only your dealt cards. If you win, save the game and play again at the maximum allowable entry fee. If you lose, turn off the system. You will have not lost any money and can try again.
