you need to figure an amount your willing to gamble AI pf with TT, JJ and QQ... for me tt may be 15BBs, for JJ+QQ maybe 20-25BBs. However his stack is 50BBs, so its worth playing proper poker.

he open limps, then there is a raise and a re-raise; THEN he re-raises... after open limping this is a dead giveaway for aa, this is where you havent comited yourself and have enough info to get away from the hand.
