PLO100 7544ss river line?

Anyway turn clear check to me.

I don´t think it´s a clear check-back, pairing King is quite a scary card to lots of mediocre/weak pair-draw combinations. Solver is bluffing with specific 75xx double-blockers no flushdraw at 36% freq whereas I personally would bluff almost always such nice blockers here against an often unprotected turn check (our SDV is supersoft and river shifts are very polar and improve our actual hand seldomly).

As played against a big sizing I would have called the river but indeed in a bet-check-bet line with 75% sizings solver would call 95% and raise 5% with the underfull of 44´s. So your argument about raising reverse blockers makes sense to me. You could make a minraise or sth., it should have the best chances to get called by flushes etc.

(edit: I personally would not exactly min-raise, rather take the 33%pot from the panel. It adds some flavour to his decision making process... )

I went for half pot raise on river and got called by AA86 nut flush blocking straight flush with 6♦:. Sizing in position is interesting topic as there is the aspect of risk:reward. Risk being mainly about opening chance for further aggression.

I doubt I will get bluffed here almost ever so my plan was to raise-fold. But in general we don't necessarily want to use very small bets in position if there is option to check. E.g. in trainer chosen sizings are half and full pot. Though again few players are capable of 3bet bluffing here.

Agree to raise-fold. Our raising range is quite value-heavy dynamics I would not care too much about balancing here either, usually being quite strong we rather exploit the lack of villains discipline than having a well balanced theoretical sound strategy. He will not be prepared to counterexploit us with an immensly difficult to apply bet-reraise or bet-call defense.

Yes I do use primarily half-pot indeed, the exploitative 1/3pot sizing makes more sense in some 3street-betting lines where river blanks or fills up obvious draws like a rainbow straight with multiple straight-rank possiblities and villain has lot of mediocre combos (overpair, top-pair, weak 2pairs), if you have somewhat solid pre-stats the amount of FE you get against many post-flop abc-players for a relatively cheap price is just extraordinary.

Another example would be monotone boards. You make your standard big sized bluff 2barrel with the flushblocker, usually the average abc reg is folding here almost anything but flushes and sets, also having no check-raising range. On the river he would be underrealizing against a small bet with his relatively strong range that was used for a passive line. So if you triplebarrel 1/3pot otr you can spcifically fold out his set-portion and the weakest (low) flushes, he will wrongly fold that against a third bet, since he does not want to get "milked". He will get less value with the stronger flushes which he has to check-call to not reopen the action against our potential nutflush. His nutflushes on the other hand will compose a very low and unbalanced check-raise/donking range we can (bet-)fold against very effectively.
