good posts nut seen yo
I disagree though in this specific case. I think a 3-bet-fold may be best preflop vs this opponent because I think he calls with a very wide range and 4-bets a range that has is beat pretty bad. I think postflop situations will be awkward sometimes but it will be worth it.
That said, if u are multitabling or don't like tough spots then calling is clearly best.
