So villain has been here for maybe 5 hands, and has yet to do anything noteworthy. The push on the river was instant. I checked and they were allin before I knew what was going on. I was trying to get some value from a busted draw/AQ type of hand, but obv afraid of sets. Do you guys make this call? Maybe make a bigger turn bet? I tanked for a while on this river.

yeah. call here always. the turn/river could not have been more perfect for you. and if he could beat one pair, he'd raise the turn. i would say:

60% missed clubs.
20% Q-x
10% float + draw on turn
10% [5c], 44, 22, AA, or some other cooler.

Bet more on turn... olther than that, standard...

I prefer betting the river myself, but if I check here with KK it is without question, with the intention of snapcalling.
