I really need to improve how i play aces. I think i overvalue them frequently postflop.

These spots are tricky deep but think its a fairly standard fold after the raise.

Also think this was a poor sizing.

it's a weird board because opponent's 3bet range contains a bunch of stuff that whiffed (all big wraps, big broadways) contains a few things that smack it such as this wrap hand, random two pairs from double suited hands or from sidecards, but equally it does have things which have you a small dog such as 987, or things that have no choice but to shove that are flipping, like a pair + oesd hands like 876x, QQ87, and a few things where you're a small fav like if they just have a bare OESD and bdfds.

I don't like folding after we bet because people can ship the weaker portions of that like QT87, T986, and actually KK especially if they have any side cards that interact in a small way like KK89, KK84. It's not great to bet then fold when you only need around 35% to call. You probably have that equity (we have 24% versus one of his near nut hands), but you could have way more if they just don't like folding a piece. I've seen good players at all stakes not fold an A6xx here or pre so I'm especially not keen on folding at 2PLO where they can show up with something weird (purely bare QQ).

This is why being 200bb deep sucks a lot because we are stuck in this position a lot where betting would leave us about a pot call behind and why 4-betting can get nasty, especially as the original opener only minraised.

Yes betting smaller is better generally I mean so many of his hands are like KQJ9, QJ98, KKxx, KTJ4ds etc that ultimately cannot peel oop here. Most continuing range is check/jamming here. Yes betting smaller means you seem less committed, and may induce more jams, but it also DOES commit you less. Checking is also an option because you don't simply want to allow him to just shove and flip it anyway, but it will require some real good laydowns and bluffcatches on the remaining two streets.

All in all though I don't think opponent actually flops enough on this board in his 3bet range, so it does compel you to bet something. Once you have it's pretty volatile: there are players who respect that oyu have AA** and think you're not folding and will simply wait to *have it* but there are ones with wide enough ranges that even if you do bet smaller, you are still fairly committed to stack off. It's a judgement call in that situation. Bet/calling always I think isn't *that* easy to exploit because it isn't that easy to outflop you but it is hella high variance because of times like this and you'll be getting it in as a small dog on average.

Too big or too small?

Thanks Strydor, really detailed analysis. I read it a few times

When you cold 4bet your hand looks a lot like aces. This can cause a problem postflop when the stacks are so deep. Spr 4ish on the flop gives villain the chance to outplay you postflop. With 100BB stacks and a potential 1 ish SPR your hand is much easier to play and the 4bet makes a lot of sense.
If you cold called the 3bet you would have the chance to jam if MP 3bet or play a pot deep stacked, in position with a disguised hand.
