AK....getting the action I wanted and then more than I wanted

[somapopper]

I think after he raises again on the turn you've gotta assume you're spliting with ak, or you're looking at a set. The only other option I see is ah q/jh. Any hand he takes this line with was misplayed pf, so I think you have to abandon putting him on a hand to some extent and just trust the postflop action.

If you must get in the extra bet, donk the river if it's a black card.
