1) You should never have 4bbs left

2) I'm putting all 4 BBs into the pot b/c the likelyhood that villain has exactly KK or 55 is slim. He coudl easily have a single 5 or a single K. You essentially have to raise the river at least once, when villain 3 bets you will have to at least call leaving you w/1 bb left. Do you really want that situation? Just throw in your last BB. If he shows down quads, take your jackpot and get outta there b/c you'll be tilt for a lil bit. If he don't got quads then you'll be 1 more BB richer, eitehr way is good.
