Actually, in SnGs and MTTs, I don't just want break even pot odds (I really don't want that is cash games either) - I want overlay from the pot - be it immediate or implied.

In SnGs in particular, if I am in a pot early, I am probaly in it for a raise and with a hand that has multibple draws.

At least one overcard.

If I have a crap hand like 86s, and the flop is A 9 7 of my suit. I will call an all-in. Even if the pot is relatively dry.

I always put a premium on winning, not survival.
