I open up to $35 in a 2/5 game and get 2 callers with KK . Flop is 8s7s2d and big blind who started hand with $600 which I have covered checks and then calls my bet of $85 and third player folds. Turn is Jd and he bets out $100 into me. Now here is what I was thinking at the time. Maybe he puts me on overpair and just hit the straight and is betting small because he has a lock on hand. I called thinking I have position and let's see what he does on river. River is the 4d. So the back door flush
also got there now and he bets out $250 and only has a little over $100 behind. I end up folding and he claims he had 56 which made a straight on the river and he bet small so I didn't bet big on the turn. Clearly my play on the turn wasn't good and i should of raised or shoved. It's easy to see now that any hand like set or 2 pair would never make that small bet and the flush draw would along with any straight draw would most likely be what he had.
I struggle at 100-150bb how to play overpairs and even tptk. Obviously it's player and situational defendant but any tips on what to look for and when is it "correct" to stack off in these situations? On these wet boards would you just not worry as much about sets or 2 pairs hitting even when you get raised on flop or turn?
