Quick hand from a $109 last week to illustrate why I lean toward calling here:

Hero limps for $30 with 99.
MP raises to $100.
SB calls, BB calls, hero calls.
Flop: J 9 6 with 2 hearts.
Hero checks. MP bets 150. SB calls. BB calls. Hero raises to 500. MP folds. SB folds. BB raises to 1100 (all-in). Hero calls 600.
BB shows 44.

WTF?

You can't just fold to these randoms b/c they "can only have a hand that beats you" because of their betting pattern.
