only had 16 hands on Button so 44/16/1 stat probably nothing to go by... UTG was quite loose and was opening hands like JQ, JT UTG so that is the reason for the initial pre flop raise.

Pre flop i put villain on 88+ or AK.. after the flop i take AK out of range.

What is the best way to get paid off on this river? will i fold out hands like 88 99? does it even matter?
