NL50 KK on an A high flop

[NSchandler]

This hand is pretty typical of how I play when an A flops in a 3-bet (or 4-bet) pot. I'm hoping it may generate some discussion so I can fix a leak if this isn't standard. Fwiw, I'm c/f both turn and river to reasonable bets. I realize my 4-bet might be a little too small.

Villain is a little loose and a little bit too passive.

I like it. Button looks to have a medium PP. You can probably even value bet river.
