I think there should be a surrender button in the blackjack game. If you have a King and a deuce, the last thing you want to do is bet, but you don't want to stay. Damned if you do, damned if you don't.

If there's a surrender button, a player surrenders and gets back a percentage (say 50%) of their initial bet.

Well i'm not exactly a gambler but i'm pretty sure in RL that you can not "fold" during a blackjack game, so i don't see why you should be able too do it here. Pros, Cons?
