NL10 SH JTs

Depending on other stats on the villain here I might go for a check-raise here against an aggro fish who's the pfr. Not sure though. If he's loose I think the overpot bet sizing is probably fine since he's gonna call you with a lot worse hands whatever the pot size so perhaps best to try to get the most value.

On the turn, I would definitely bet here against a fish to get the most value and definitely fire on the river as well. He's going to call you with a lot hands that you beat. You might want to bet the river a bit bigger, though.

On the river, a shove over his raise is fine. He's so loose and aggressive, he's probably gonna raise/call you with a lot of flushes and straigts and sets. So, I think your play is fine, you just got coolered.

Hello Mopenza,

Well, first of all you should already Bet the turn yourself. But as played kinda dumb spot, most likely I'd still bet a bit bigger ~$0,80. But as he raises I doubt that I am getting away.

The question rather is what his overall range can be there. Most likely he may even raise there with a lot of flushes but as well may have QJ or whatsoever hands. For example:

Board: 4♣T♠J♠ J♦ Q♠
       Equity     Win     Tie
UTG    35.00%  30.00%   5.00% { QJs, JTs, AsKs, AsQs, AsJs, AsTs, As9s, Ks9s, As8s, Ks8s, 9s8s, As7s, Ks7s, As6s, 7s6s, As5s, 6s5s, As4s, As3s, As2s, QJo, JTo }
UTG+1  65.00%  60.00%   5.00% { JcTc }

As you see against his made flushes, FH and of course made straight flushes it's still considerable to raise. But the question is if he really can have such a wide range? You should have some kind of overview with the 150+ hands.

Although most likely he would have Bet the turn with Jx. So we might even exclude QJ.

Best Regards.
