My thinking (shoulda put this in the OP). Guy is a TAA (Mungos, 504 hands, 17.3/10.7/3.29 with a 59% attempt to steal), I don't do this against unknowns or players that won't fold, no value in it. He raises PF from a steal pos. Most likely he is stealing and does not have made hand (Pair) yet. Then this very coordianted flop. This misses most hands, and you need

or a 6 to keep playing here. There are very few hands that can keep playing here, so I'm going to show real strength and CR this. This was an insta-CR, not a pondering one. I wanted to make it clear to him there was no doubt in my mind he was getting CR'd. Put yourself in his shoes as a good player, what are you thinking now?
This was not blind aggression, this was a calculated shot to hopefully buy a pot.
