Open Ks vs 4 others on 5th

[gergery]

Just picked STud up, fun game.

I'd have easily folded on 3rd with bad position, a dead K, and what seems to be a loose table.

On 5th, I don't mind check-folding since its pretty likely the open 6's are now a set since I can't put him on 55,77,bigpair, or 3 flush as his holecards given others cards and the action. and you're going to act first, and pot is not huge. even if you're ahead to something like his (88) 66, you still need to dodge outs and avoid other guy's flush, etc.
I might also have chk-rsd him and folded to a 3bet, planning on check-calling down if not. I like leading least of all there. but i think its a tough spot.
