What's your reasoning for checking flop?

Raise turn sometimes,,,

being OOP means he will also check behind a worse hand on river aswell as countering the validity of the turn check raise. Against alot of Ks and no 'upped' A, turn will be against a mostly calling or folding range and river will be somewhat tricky but there is capacity to outplay opponent still, half the deck is a 'switch'

It hinges on if you are CR'ing the top of your range on flop, which should actually not be so common in your play imo with A hi board and being the preflop aggressor, that in itself hinges on the meta in vacuum which at default is 'you are cr'ing the top of your range' in that robotic sense (plo25-200z and this idea of meta is becoming weaker as opponent skill increases). Relationship with villain is going to pivot it without much weight. It's a good opportunity to surprise him or create a setup later with the CC into CR. I would check how many tables he is palying and hopefully you have seena showdown hand, you say he is loose so it should work there, especially if you tank pot it to induce 78 w/draw or the 35% combo, or fast 50% pot it. AKKss will call which is still good. AA crushing you not likely, his A/*8* is somewhat blocked too

We're somewhat bluff-catching but I think I like a river call. Button's range can be super-wide and its easy for him to have a missed flush draw or missed wrap of some sort.

fyp

river is a muck, if he is bad enough to not use a lower sizing or have specifically 88/AK there then he can have it this time imo

He's a completely unknown villain so I'm not going to rule out that he's just betting random 2pair for value on this board with no flushes or straights. We're also at the upper end of our c/c, c/c, c range.

pre seems close to me. I'd tend to fold this unless the players behind are tight or fishy and start opening it from the CO. As played I'd call the river having no blockers to his missed bluffs and having a very underrepped hand. It's still close tho because people are generally quite honest at these stakes.
I'd mostly just cbet though unless he's raising really wide.

It's subjective, i.e i clearly don't have this hand at all in cc cc on this board, although i'm notentirely sure of your semantical understanding of 'upper end' as often times the top of a range becomes thinner, you can't put something on 0% weight too often

this sizing he uses on river, it looks polarised to fold out hands he would want a call from with worse and uses this to get calls with the top of his range also... as villain with the lower part of my value range I am betting low into call or low into fold, who do you ~pot say K8/A2 against? It seems very unorthodox

I can't see how check/calling the flop is going to be better than betting. Our hand needs protection and it doesn't play exceptionally well on future streets. Getting raised on this board is not a big concern at all when cbetting in this particular spot.

Well, you don't need much protection from the hands that fold to a single cbet so keeping the pot small, in a sense drawing to a blank turn and having a disguised and strong bluffcatcher on a lot of runouts has some merit.
I still very strongly prefer to do this kinda play IP though.

Easy call with all the bricked draws and he sizes so big otr so it seems like he is trying to get you to fold, not crying call with a bluffcatcher. And I agree you can shove turn if you know he'll call with worse 2 pr and lots of different draws. Shoving turn actually makes it easier to play as you don't put yourself in a tough spot on lots of rivers where draws get there but you're unsure of whether he got there or not

I certainly cbet the flop.

Readless on PLO25 you can prolly fold river to the potsize barrel, but std against decent opposition has to be calling down

River looks like an easy call with just an ace. He has just AK+ for value and many many missed draws.
