Bluff fish

River is a check/fold for me. You tried double barrel bluff, it didnt work and river is bad for third barrel. Whatever called you on flop and turn is not likely to fold this river. Just give up and move on. Occasionally you will even win showdown against busted draws.

Not a great flop to cbet on, nor a good turn to try another barrel. I would only try double barreling here against regs who know when to fold, not against fish. River I would give up, check/fold.

i think you don't have stats from the villain
Your calling range is high in BB, pocket pairs,suited connectors is in your range.
II would bet flop maybe, turn is acceptable too, but without stats it's more complicated.
River an easy check/fold.

dont iso. youre already HU. the rake is high.

The turn should be good for BU’s range , , QTs,JT,T9s get top pair, 98s has trips, 87s has boat, J9s turned a straight. They should have hit this board with a fair amount of their range
