Hand from deep in a sunday challenge. River line?

[dakky]

There hasn't been a new hand on here for a while so I thought I'd throw this one out.

Villain is a good reg. I guess my hand looks like AK/AQ a ton, with or without a spade. If I had AK or AQ I would fold to river raise if I played it like this. I expected his floats and flushes to bet turn, sets/2p to likely raise flop (and there aren't any 2pairs really as he's unlikely to peel A8sooted. A3soots is more likely but there is only one combo of that. A river raise from him with that seems thin also).

It is just so hard for him to be bluffing here. I am also unlikely to be bluffing, however. I guess it looks like the nuts KQss a decent amount of the time for him? Anyways I tanked right down and figured I needed to win approx 22% of the time...

I think i'd fold.

It's really interesting his check back on the Turn.

Pretty much we have no flushes here, I don't think. Unless specifically we know the player is aggro and is unlikely to be able to call but will bet this turn card a high % of the time, but that's a really specific read.

Again would expect him to be betting the turn with all Flushes/ x hands, not that he has many, if any, x hands.

The raise on the river to an extent does look a bit FOS given the turn action. But the vast majority of players wouldn't ever be bluffing here, especially given I can't see him having only the K of spades here in his hand.

Ths sizing is also a bit concerning, looks like he's wanting a call.

Overall, while his raise looks a bit suspicious (why did they not bet turned flush) but with sizing the fact it's an unlikely bluff I feel he prob does have a flush here.

Really interesting hand.
