QQ OOP vs unknown, K drawy board, 3bet pot

The flop isn't so bad, you've got blockers. Well, about the river, you wrote u didn't see him betting worse, you should have thought about equity, I noticed all you guys playing micros forgot about counting some basics stuff. That's a call from me.

what can we beat from hes range in dis situattion ?
I guess only 77+ mybe AQ buff, Ax miseed draws. i think hes not value betting hes AJ.

We can call the river for that price.

I think x back OTF is very good option to consider. As played river is tough, probably you have to make a call, you very good odds.

I would check/call the flop when we don't have at least TP and we have a 2nd nut flushdraw. Without Q♠: I would bet. We can probably check/call the turn, too, especially if he bets that small, but then check/fold the river.

I think OTF a check/call or a bet is fine... a lot of player bet on missed cbet but also a lot of player float so either is fine.
the turn bet is small and it could well be a float. By calling you also often rep a draw. and it's fine but it does invite a river bet on the river if you check again. The bet is small again so IMO it is an easy call.
