I see your points, but I just didn't feel the nit is going to play for stacks with AK here vs my 4bet. The collective wisdom of the board leans toward 4 betting and I guess that is better as the tight squeezer is likely to not folding. Allowing the other guy in for a discount isn't great either.

G, as for overcards on the flop, I'm not terribly concerned as I hold 2 Aces, but your point is valid and likely tips the scales toward 4betting.

Thanks everyone.
