Suited Connectors

You likely know that suited connectors like 8♣7♣ are strong hands, but many players consistently play these hands in spots where they're not that valuable. Suited connectors are extremely powerful when the stacks are deep -- not because they win often, but because when they do, they can potentially take down huge pots by making a straight or a flush.

On the other hand, it's not worth playing a hand like 8♣7♣ if the stacks are short or there's going to be an early all-in situation. The problem here is that you simply won't win pots often enough to show a profit against the kinds of hands you're likely to see if an opponent is moving all-in. Instead, hands like A♦6♥ -- a hand that is terrible with deep stacks -- makes a much better hand for taking down a player who is all-in with a short stack, especially in tournament play.
