Button had been somewhat tight for the 22's, but he is at the point where he is getting desperate and I think is pushing a large enough range for me to call. When I put this into SNPT with the loose push range it tells me it is +$EV to call. My question is how does SNPT deal with the times I fold and the BB calls? You do not put in a call range for the BB, so is SNPT assuming the BB will fold if I fold?
