Of course you fold. I'm so amazed that somehow, lately, A-J has become THE hand to play like it's AA preflop (not saying you - just in general. I see you're in the sb there). Pirate might be trying to steal with his big stack backing it, but nah calls with his own big stack so you're at least behind to a pp, but likely have one of your outs (A) already dead. You've got a reraise to all-in, so action is going to be dead unless you hit solid, but you're puttin out 50% of your stack preflop on a draw.
