i agree w/ pretty much everything amak has said.

i don't doubt 3-betting pf is +cEV, and i have no proof, but feel that flatting yields a higher cEV vs. this and most thinking villains under most circumstances.

though there are definitely some situations where either of you have a really laggy image or there is some recent history that would make his opening and 4-betting range wider where i could see 3-bet/calling being more +cEV than flatting.
