Bet Size/Line check for a Triple Barrel Bluff - 100NL

Villain is 20/16 fold to 3B: 70% over 560+ hands. He normally raises to $4 PF. He was 3betted twice, that I can remember in the recent couple of rounds, when he made it $3 from CO/BU, both times the 3bet was $12 and he folded. One was from me. My OOP 3bets are a lil bigger than my IP 3bets since my IP 3bets are more polarized than my OOP 3bets (leak?), unless im squeezing with a caller in between.

I rarely ever triple barrel bluff. The way he played the hand, he almost never has a Q. Looks more like a badly played AA/KK or at worse JJ/TT/99. I was gonna give up after flop but the Q on turn was a good card for me. Think this is an optimal spot to triple barrel here, but not sure whats a good bet size. I ended up betting $50 and thought it was too small afterward.

If villain is a thinking player your bet sizing is fine, the board is so dry you don't need to protect against anything so you can bet purely for value. Your only repping a very small number of hands and if villain is getting frustrated he might call you down with JJ+ and AQ but I like it. Most of the time he is giong to fold if your image is clean.

I check behind river.

you are trying to get a 100nl player to fold for 50$ into a 100$ pot? good luck sir.

also don't 3bet preflop

Yah I agree with nuts, on not 3betting this hand PF against an UTG opener.

If I was going to bluff this river, I'd probably bet stronger around 77-83. But I'd probably just shutdown on turn, as its a pretty bad card to barrel, and he's not going to believe you.

Bet more on the turn, shove the river.

Pre-flop is non-standard and meh.
