This might be obvious to some but not to others so I think it's worth mentioning.

Here's a typical scenario: A limps, B limps, C raises, you call, A+B call.

Flop: xxx

A checks, B checks, C bets...

Now say you have a good but not great hand. In any case, you think there exists a reasonable chance you have C beat, though you're not too sure (TPGK, for instance), and heads-up you would call. The presence of players A and B makes this a FOLD! The presence of the other players in the hand makes a marginal (or even slightly better than maringal) call into a fold, since you're fighting an uphill battle now, and should someone wake up behind with a hand, you're screwed.

There's more to it than that, but I'll stop here for now. Comments? Thoughts?
