i agree basically 100% w/ what mcat said.

i'll add this ... anyone you perceive to be a good player flatting a 4bet either isnt as good as u thought or has to have a VERY strong hand. Reason being ... he has zero implied odds to make any kind of hand, and he should be folding or 5betting all in anyways. This flatting of a 4bet I've seen done by tournament players quite a bit, w/ something like QQ not looking to get in preflop but looking for a non a/k flop. it's a very terrible, -ev play, i highly recommend against it, and would probably think less of anyone who did it.
