2/5, 9 handed, $600 effective. SB is new to the table, but has done some limp-calling in the few hands that I have seen. BTN seems like the stereotypical LLSNL loose passive player.

. SB checks, hero bets $40, BTN calls, and SB x-r to $180. Hero? Do we call or 3 bet? Vs good players 3 ways, I'm assuming this board is an easy x-c. However, are we making a mistake in c betting vs presumably two weak villains?
