JJ facing HUGE overbet

betting this flop is no good.

[/ QUOTE ]...because villain seems aggro based on what we've seen in the OP (which is very little info)

OP needs to give us more information to determine if betting is not a good idea: if villain has been calling hero down in order to adjust to hero taking pots from him, hero should be betting. if villain is c/raising type, then hero should consider checking behind in this spot.
