I've never seen this before:
1-2 NL game at Parx Sunday morning. We had just opened the table at 11 AM. Around 11:30 the 5 seat leaves. I'm in the 6 move over to the 5 (easier for me to see the flop). A young drunk (I'm assuming been up all night) saunters over and says, "who wants to flip for stacks?" We think he's joking, until he sits down and puts his $169 across the line.
I'm UTG+2 which makes him UTG+3 (he took my seat).
Not quite knowing the rules, the UTG and me clarify with the dealer and the floor - if we don't change the action (so either fold, or call the $2 BB), then he's committed. If either one of us raises then he'd have the option to pull back his bet.
UTG folds, I look down at K6o. What's my play?
