Q5s Rivered trips vs River donk shove

I would play like this postflop as well.

I guess it is ok. Flop bet could be a bit smaller in 3bet pots and I'm not sure if betting turn is very good. We still get calls from some draws though if we bet. OTR villains line is strong and since no draws complete he reps mostly Qx and fullhouses. And his Qx is probably higher than yours. I would be tempted to call too but against some villains I think it would be ok to fold too.

All the hands that 3x the button and call a 3b and also call you down twice beat you. I see only AJ or AK with atleast 1 club as possible bluffs. But why would he gamble on a bluff with the info that you 3b and bet twice on a scary board?
Fold.

RE: Oh wait, scratch that, your title is misleading, hes not donking river because hes IP and you check. So he's not actually bluffing randomly. Its alot closer now. I would call probably too. The correct play on his part would be to bet small when hes bluffing because he wants to fold out A and K high, but that does not mean he would do such things and may pot shove as a bluff instead.

I am giving up on turn. (Have a look at the board and the buttons range.) We have bluffed enough already. The minuscule hope that he is on a draw and will miss the draw and will bluff river and we call down (so we win a big pot the few times we win) isn't enough for further engagement. Not even nearly.

His bet looks alot like a busted draw. I don't think he would bet KQ like that. TT and 99 and KJ are probably raising flop or turn. KJ is maybe even not calling preflop (even KJs should).

I will not bet turn. Board hits his call3b range.

On such wet board, you are playing pretty dangerous. I think I would call river here as well as villain can have some lower hands that try to get you off the hand as well.

la55i - what sizing would you recommend on the Flop?

yeah I thought that Turn cbet is kinda thin, but I thought there is still a lot of draws to get paid from

A rule of tumb is that in 3b pots we can cbet around 1/2 psb.
