1/2 6max Semi deep 4bet pot

[carnivalhobo]

opponent and i hadnt tangled much, but he starts with 342 and i cover. I was playing pretty snug but insanely agro postflop, 17/8/oo. I had been 3betting light a bit but nothing too out of line. Villain is TAG but a bit passive. I am capable of 4betting more than AA/KK here but i dont know if he knows that.

Who likes the 4bet, and who plays the flop differently?
