Your preflop call on the reraise inst the greatest,you can probbly safely fold without exception but onece you have called what re you looking for. A jack high flop is probably a nightmare as you'll have top pair and probably be behind. An ace may be good, but it seems unlikely. That leaves you with two pair or a flush draw. You get neiher of these on teh flop so even though your putting nothing in the pot you dont have anything either. Id be tempted to fold it ten once you know yourself you ve made a sloppy preflop call
