Villian is a reg. 12 / 10 / 5.5 ~6.5K hands. 3bet from each position ( ex EP) is 6 and on BB its 5. Had a note that he had folded to 4 bet in same situation. Fold to 4 bet is 33% ou of 15 .
Is that a good flop to cbet or not, and how big should the betsizing be?

this is a terrible hand to 4bet, especially against a 33% fold to 4bet. Seriously just fold pre?

If you did 4bet, sizing is a little large but ok.

flop is good for a cbet. cbet sizing is too large. Make it $4 on this texture.

Not a good spot to drop this 4b on. May want to just fold here PF, or just call and look for a good flop if they don't raise. There are better spots. If he's playing this tight and he's reraised you PF, then I don't think a bet OTF would be wise. He's repping AA-JJ. You whiffed, it's ok to let this one go and save the money.

Were you just trying to blind steal, or what gave you the impression you could pull this off? Was he playing extra tight or folding alot of his SB's?

What was your reason for 4-betting this guy with 98s?

As said this is a horrible 4bet.

As played, check back the flop, and thank the poker gods if the 10 of hearts comes out.

I think the 4bet is fine if reg 3bets a lot from blinds and we have this much history on him. He can probably start giving hero less credit when he 4bets if hero does it a lot. It helps you get paid off later with bigger hands. 5% 3bet from BB isn't really that high though and I'd be reluctant to 4bet initially. I'd have to think about table dynamics. I'd also consider if I really hated the guy just doing this to piss him off a lot and make him tilt.

That being said, we're playing it as a bluff preflop and that flop really doesn't give you any realistic chance to improve. Seems like villain has an ace here a lot of the time to me. He might not even fold KK if he puts you on something like QQ or KJ, QJ. I'd probably just check back flop and give up because once you cbet you have put so much in that even if folding is correct your play has to be -EV from the excess amount you've committed vs the equity of your hand. If say the A is the A of hearts, we can properly bet and get it in because the times he folds we win and the times we draw out when he calls should make up for the losses we incur when he hits.

Firts of all yes i was blind stealing BB was a nit too. Secondly i 4 bet him because i had hitory with him that in same situations, and this one was the first one he called. I just cant every time i steal he insa resteal and i fold if i dont have AK +
Are you guys reading what i write before the hand history.
Obv i dont 4 bet this hand agenst any other villian.

Would we not just want to flat 89s IP if we felt that villain's range was wide enough to not just simply fold?

I know you have a note that villain has folded to a 4bet in a LP battle, but you also have a stat that he only folds to 33% of 4bets. It's a pretty small sample, but I'd not be 4betting a polarised range against this villain.
