With 87 hitting top two on the flop, you can expect that an overcard was coming on the turn or river, and I would have taken a stronger stab then.
^^ This is a really good point.
he could be exploiting Hero's timidity.
^^ This is also a really good point -- you've really underrepresented the strength of
your hand by just flatting the flop. When you lead for 1/2 pot, $35 on the turn, what does Villian think you have? Does he read your bet as weak? Does he think you're trying to steal it? If he thinks
you've got a draw or a weak 1 pair, he could be raising with a strong 1 pair hand or worse 2 pair hand, or even a bluff of his own, if he thinks you will fold. Since Villian was BB and saw flop for free, his range is literally any 2 cards, maybe some bluffs, if turn brought a backdoor flush draw. Is it even possible Villain has a hand like A9 or A6 suited, with an overcard(s), backdoor flush & backdoor straight draws, and hit the A?
As played, minus any live reads/'opponent's a nit' type of thing, I'm probably shoving/never folding here on the turn, for the size of the pot and the stacks behind (around $135 more for you to put opponent all-in. (If stacks were deeper, it'd be a different story. Also, if preflop action had been different, and Villain had
called a
raise preflop from the BB, then it's different, he's rarely got 82 or 72 in that case.)
If he's got the few combinations of 22, 77, 88, A8, A7, (or A2 - which would be pretty gross), then you lose. Everything else you beat (right now).
