When you sit at a table and the cards are dealt, save the game before betting. You can then move all in or bet the maximum amount. If you lose the hand, just exit out of the game, and load your saved game. When you are back at the table, you will have the same cards as before, and the outcome will be the exactly same as it was when you lost. Simply fold instead of betting. Also, if you save the game and decide to fold but realize you would have had a monster hand, just reload the game and play the hand. The outcome will be the exactly the same again.
