Now lets take a look at what happens if we surrender the hand. If you bet a buck a hand and surrender you get back 50 cents. When you are playing in multiple deck blackjack games you should only surrender these hands. For a two deck blackjack game you need to modify the above and surrender only these hands. The casinos make a lot of money with the surrender rule from players who surrender hands when they shouldn't.
Surrender is a unique blackjack option.
Also remember that if you were to ask for a third card draw the surrender option is no longer available. Because of the latter rule, the above surrender playing rules are known as late surrender. If you find a casino that allows you to surrender your hand before the dealer checks if he has a blackjack hand, then surrender is known as early surrender. It doesn't seem like much, but your objective if you are serious about winning is to play as smart as possible to cut the casino's edge to as low as possible. Surrendering will help you achieve this goal.
