Tough hand, AK 3-bet pot, fold or call river?

[Up-grey-de]

Would you call his river bet here? When he calls turn, what do you put him on? I do not think he will bet allin here with AJ.

Villian runs around 26/19. Villian has 100BB, Hero covers. 6-max, 1/2.

Hero is dealt: K[img]/images/graemlins/diamond.gif[/img] A[img]/images/graemlins/heart.gif[/img]
