JJ line 30$ missed value?

Why are you not cbetting the flop? He is a fish so you need to valuetown these guys imo. So my line would be bet/bet/get it in if he doesn't show any resistance. If he does have Qx, he will let you know on the flop or turn, if he doesn't, you will be able to get all his chips and you are not left with a guessing game on the river here.

As played, the only reasonable combo he would call you with is QT so I don't like shoving the river because I don't think you will get value from any worse hands. About the clickr, why would you clickr/f and leave 9BB behind? Seems like a huge waste of chips to me.

Flop cbet versus passive looking fish would be standard. If I have doubts of that then checking is fine too imo.

Just calling river versus huge fish like that is veeeery nitty for me. Ok he can have some straights, but I would think he is not folding top pair. At least not KQ+, but even some Q8 can be nuts for these fellows.

i would definitely cbet, so many draws and Tx we can get value from.

as played I would think about raising the turn because to me it is pretty clear he does not have Qx with this size.

river as played, i would raise small and fold to a 3bet.

For me raise-folding river would look questionable with these stack depths. Can we really say he thinks only straights as nuts? Player like this can have lot of 2 pair combinations also. E.g crappy hands like Q6 or J6. If we raise to 700 and villain does shove we would have 900 to call for pot of 3700 or so.

Anyway I would be worried we end up folding best hand too often.

Main reason why i like small raise on river is to get more value. I think his call frequency for a small raise is much higher than any other size, and flatting is losing value imo.

What to do on the river facing a 3bet is the least important thing in this hand and it wont happen very often. You can just decide in game how bad he is and whether it is worth the pot odds to call it off if it happens.
