I think this is a fold. You can have all the sets, 57s, and all the over pairs. I don't think villain can have all of those. I'm not sure what blinds you're playing, but I think the lower they are, the less likely villain is bluffing. And if he's not bluffing, he has a set (or maybe a very occasional 75s). Maybe in theory, this is a call or a marginal decision. Here, I think most micros players would bet lower with a bluff, and would be check raising flop with a spade FD if they were inclined to bluff with that hand.
I'm doing a bigger sizing otf, like 7bb in a 3way pot. board is somewhat wet and we have a huge hand in this spot vs a fish utg.
on the turn im just folding as well. We block bdfd and our opponents range is most of the time 2p+. Doesn't really make sense from his view to get it in with worse or draws imo.
That 8 completes nothing. I'm calling; I'm a station.
As far as the raise size meaning anything, a 45bb (3x) raise and call would create a 109bb pot, leaving 50bb behind. Might as well just stick it in and make a difficult decision.
