If I fold, I'll have t646.
If I call and lose, I'll have t396.
If I call and win, I'll have t1271.

With 2 other small stacks, it would be difficult to fold my way into the money. So, it would seem that if I fold, I'm going to have to push before the blinds hit me again.

If I call and win I double up and if I fold, push a later hand and win, I'll also double up. The difference is that if I call and lose now, I still have t396 left, but if I push and lose later, I'll be eliminated.

So, do you call with a weak hand now or hope to push a strong hand later?
