If he's min-raising 25% or more of his hands, then I make it $3 flat with AJs, ignore his flop bet and fire off on any flop.
In general, with these guys I just put on my LHE cap and draw to anything getting odds. The only part where this gets annoying is when they over-bet the next street. However, with a read it's certainly exploitable.
These guys are a blast if you give them position. Just check for information and see what the field does...
