Hero is multitabling TAG and has been pretty nitty, not to mention carddead - have only 3bet once this session (they folded)

This guy bluff pushed my flop raise last big hand we played (see other post) - this time he c/r and dumps most of his stack in teh middle.

Is this ever a call?

I hate this flop, his betting pattern this hand is way stronger (?) best to get out with chipstack intact? (ish) or does his previous history make this a call? (if he knows last time I caught him bluffing - has he switched his bet sizing now - or is that just waaaaay over thinking things?)

I know he calls 3bets with a wide range and is capable of bluffing here. I think if he pushed the flop OTT of my CB I'd lean towards calling - if the flop comes Q[img]/images/graemlins/spade.gif[/img]6[img]/images/graemlins/spade.gif[/img]6[img]/images/graemlins/club.gif[/img] I call here probably.

I don't want to check the flop as then I am facing the same problem on the turn (he'll lead, and if I call we are playing for stacks) and there are a bunch of turn cards I'd hate to see and just the J[img]/images/graemlins/club.gif[/img] that I'd like.
