Hey 2+2, another HH and another weird spot, all feedback welcome. Thanks

Literally no clue OTR tbh, I can't really assign villain a range taking this line. Decided to fold purely because we rarely beat any value on such a scary board and have a pretty bad blocker with Ks.

Your potential call on the river needs to win 27 percent of the time to break even. Stats on Vil indicate he might like to play suited cards, and one Ks blocker might not be reason enough to eject on river.

6-handed I'm tempted to call here, and maybe have reraised flop and gii also.

I probably pay it off.

Any reasoning?

It's really difficult to put him on a hand that has you beat. Would he play a flopped set like this?

AT or A8 maybe

I don't get why he cheks behind you on the turn, thats why I rule out sets etc. I guess he puts you on a busted flushdraw at the end, when you check to him. He is obliged to bet with any hand at the river.

I would be more aggressive with my AK in this spot.

he has 7c8c or 7h8h
