Another AK OOP Hand...

I think there's atleast a 5% chance villian is bluffing here and more then a 10% chance he is doing this with KT-KQ.
I don't know if you have any reads on villian, but I've seen the typical partydonks™ do this with KT-KQ many many times.
That being said I like a c/c on the river more, villian might have read you for a flush draw here, since your line is consistent with a nut fdraw here IMHO, he might even have put you on something like QQ-JJ and make a very small vb on the river with a set or something like KJ giving you a cheap showdown.
If you are beat on the river here 100% of the time maybe it's time to start thinking about changing game to 6max or work on your table selection, in this thread most seems to assume villian plays extremly good and, well, maybe he is.
But then, if everyone plays this good at 50NL full ring why play that game? That's more -EV then making the wrong decision on this river.
