he is raising it to 5 every round. It does sound pretty exploitable but it aint that easy. Unless u have pocket rockets or kings. If he raise to $5..got 2 callers (after awhile everyone seems to be willing to gamble for $5 because of him)..what range of hands do you reraise with? And there is always a chance someone is limping in to reraise him since the blinds are $1. If someone pick up a monster they will definately go for the limp raise. So unless u have AA or KK, its just too dangerous to raise here. If u pick up suited connectors or a small pair, u are risking 5% of your stake at min and if someone reraise behind u, u are going to fold your hand.
