Not exactly sure what I said, maybe I misspoke, but sounds like you're kind of inverting what I meant.  I use CTS as an example because he's someone that I watched while learning the game and I respect his ability as much as anyone in the world. Yes, a tighter player's range is usually more polarized(although I think I mention that alot of nitty-type players are the opposite by being all value) and a hyper-aggro player is usually more merged, but I do not want to put myself in a marginally EV spot by 4betting 77 or something that merges MY range too much.  However, if it was a spot where I felt this specific player was vvvvv likely to jam or play back, it's possible.

What I think I meant in the video was that an aggro player who is being played back against can more easily 3bet/bet marginal hands because they have to expect players to play back with a wide enough range(both weaker balue and more air) to get those hands in profitably. 

Hope that made sense.
