jharding was it you who posted that thing cts wrote about 4 bet shoving? Didn't he say he gets looser calls when he shoves than he does from people pushing over a normal sized 4bet?
I would agree with wota that a $500-600 4bet would look soooooooo much stronger than a shove. He knows you're committed anyway so I'm guessing he'd be more afraid that you're trying to tempt him in with the smaller raise.
That said I don't 4bet shove much in those spots cos I'm a pussy, I put in the smaller 4bet and get called and cry at the ace on the flop.
