$33 6-max K6 fullhouse facing bet on river, how much to raise

[1outer]

3 handed, Aggressive player to my right and I have been staying away from eachother just picking on player to my left who is weak-tight and recently won AI PF pot with Q9o vs. JsJc. This player was very weak postflop and folded to every re-raise he encountered. When he raises me on the river, what do i raise to get max value out of my hand (pot? push?) He was defending made hands and from what I had seen, was not slow playing anything. Your thoughts?

somewhere between 900-1500 seems right.

First, c-bet this flop. As played I'd raise to 1300ish. I would only push this if I had been extrememly active and/or got caught bluffing recently.

Up until 3 handed play he was playing extremely weak tight. Now, I realize that he really wasn't playing so tight anymore, he was calling raises pretty liberally to see a flop. If he hit, he would bet, if he missed, he would knuckle. I checked the flop because I felt he was calling with a wide range of hands and he could easily have had air. There were plenty of times that I got headup with him in pots and I would just make standard cbet (2/3 pot mostly) and he would instamuck if he had nothing.

Myself and player to the right were being super aggro and taking turns raising every other pot. I didn't put him on q10 and up because I felt like with all the active PF raising going on between two stacks, qk would almost become a 3betting hand preflop. Was my thinking wrong?
