with his stats and 0/25 3bet I'd be thinking along the lines KK,AA,AK as his 3betting range unless he showed down otherwise. I think I'd check call up to half pot here as half his 3betting combinations are AK. Betting the river here will fold out those AK combos that you beat and let him shove over with his AA KK. If you check the river , it lets him bluff with his AK and if he shoves you saved yourself the $1.60.
