Hi. Villain is a pretty aggressive that has been getting increasingly suspicious of my 3/4bets. I have caught him turning middle pair into a bluff on the river, shoving over a 55% pot bet by me on the river in a 4 bet pot. That time he had a OESD with the pair of 9s and the board was like QsJhTsQc5c. That time i bet really small OTT because the hand started with a 3 bet and 3 calls after which I 4 bet huge because we were deep.
OTR I had quads so wasn't really tripping.

In this hand I feel like I completely botched the river. Somehow I knew he either had a set KQ or complete air but because of history and his aggressiveness I check called the river when I think I should've bet small and folded to a raise or just X/F.
Thinking clearly I see his most probable range OTT as KQ or sets because I double block AK.
Id jus't like some input on how some of you would've played this hand different.
