Villain in this hand is a pretty decent player - he lacks theoretical knowledge, but he has a good feeling for the game. He considers me the best player in this game and he wants to battle with me. He's learned a lot from playing many hours with me - he is aggressive preflop, 3betting and 4betting, his sizings are usually on point both pre and post.
That said, in this game he was drunk. It was not the first time. In his case, being drunk means playing much looser preflop, straddling, floating a lot, but not doing anything crazy/spazzing postflop.
I have quite some history with him. In the past few months, there were approximately 5-6 spots where he raised or check-raised me on the river in big pots, and I always paid him off, and he always had the nuts. (I made adjustments since the last time I did that, folding more to aggression in live games in general, especially to river aggression). In fact, I don't remember the last time he showed a bluff when raising on the river, and we play quite often together.

Things of note/"live reads" during the hand - on the turn he SNAP called the $260. On the river, it took him maybe 4 seconds max to shove. When I was in the tank after he shoved, I tried talking to him a bit and was thinking out loud. When I was listing the hands he could have for value (T9, 88, QQ, etc.) he asked, smiling: "Do you have a set?". After I heard that, I dismissed the possibility that he could be shoving with a worse value hand, which crossed my mind at first.
