We tend to see, when a player is faced with a current bet amount that he has insufficient remaining stake to call but he wishes to call, he bets the remainder of his stake and declares himself All in. He now is entitled to hold his cards and see the showdown as if he had called every bet. He may lose all his money; He may double his stake. It's like a classic Martingale betting style, in which gamblers will increase their bets after each loss in hopes that an eventual win will recover all previous losses.

Act as if you have nothing to lose; Live as if today is the last day.
