What do we do here ? The flop check is weird. Hard to put him on a range other than flushes there ? Maybe AsKx turned into a bluff? Without blocking any spades can we find a fold there? We would also have alot of flushes by the river as well as some straights (8x) altough not very often mp vs ep..

I'm not sure what he could be bluffing with and potentially could shove KK+ I guess.

Toughts?
