me and the villain in the hand are ~180bb deep (370$ or so), the fish has like 48$ to start the hand. I'm playing these games after a pretty long break, so we don't really know each other. His stats are 18\13 over 400 hands, but he's pretty spewy and cally postflop - he opened A3cc UTG once, I called with AQ in HJ and another big fish called in SB, flop came K63hh, fish checked, he checked, i bet 2\3 pot and they both called, i shut down on the turn, the hand went to showdown and the villain rivered trips. Onto the hand.
Big fish opens 3x, shortstack fish calls, villain calls on the button, i call T9hh in SB, 9\7 bb folds.
Flop: K

(pot is around 26$)
c/c sucks, c/r sucks, so i donk out 18$, big fish folds, shortstacker calls, villain calls.
Turn: Q

(pot is ~80$, me and the reg have 340$ left or so, the fish has 1\2 pot left at best)
What do we do now? betting and c/r seem reasonable and have their own merits, can't decide which one is better, though
