No reads in the situation. I wonder whether or not Villain is on a small pair that folds to an all-in bet enough of the time to make firing a second barrel worthwhile.

[Knuckles]

I don't think that the second barrel is in order on this flop. The turn card didn't improve your hand or anything that the villain could put you on. I would be looking to c/f here against an unknown opponent.

[Bodhidharma]

I would never double barrel without knowing who I'm double barreling against. I'd just give up on the turn.

[Pokey]

Villain raised preflop from MP, called a big reraise, and then paid off a significant flop bet. Your hand is dead. Even worse, you have no folding equity left. Check/fold the turn. If you get a river card, check/fold any card that doesn't actually improve your hand.

You're done -- reload and move on.
