Seems wp, checking flop/turn is pretty bad imo since he can call with plenty of worse hands on both flop/turn+most of his hands that do stab will call your bet anyways. I also expect him to check back a good portion of his overcard hands so it's nice not to let him realize equity for free with that portion of his range.

I'd fold river, people aren't 3 barreling enough on these dry-ish boards . Some of his bluffs also caught up otr.

as played would just jam turn but really no reason to raise flop esp with such a small sizing

Yea... just x/back that flop imo, you're cbetting too often if you cbet A5hh on that board. I think river is closer than you think since when he x/c, x, bets river he has a pretty strong range imo esp because you rarely get to the river with total air. I also think this is a spot where people won't have enough bluffs at 25nl so he's going to be pretty value heavy when he bets the river. But then again, I would have x/backed flop.

Call. He only has 55 (1), 44 (3), 45s (2) that beat you and he can do this with lots of 5x if he's a fish. You're definitely right >25% of the time.

Think the call pf might be a bit too loose, I'd shove otf as well, don't think you're losing much value since I'd expect sb to be pot committed once he leads flop so large and lots of overpairs/fd w. overcards will call a shove. His other hands aren't going to barrel/will probably find a fold ott anyways+it's kinda nasty seeing a turn 3way w. no hearts in our hand.

I fold, it's gross but fish aren't taking the minr/overbet/shove 1.5x pot line with anything but the nuts. Unless you have some notes on him being a spectacular spewtard I don't think he has much 4Q/Q8/48 in his range either since those hands are more inclined to bet smaller.
