I failed to mention that I don't 3bet hands I can call with profitably negating the positional advantage of those hands, Like SC and gappers. I will 3bet more broadway offsuit and suited A type hands that calling would not be a good situation IP.

most of the 3bets are vs either loose CO opens, nit EP openers that call 3bets and fold flops or just against guys that are easily predictable post flop.
