KK oop and an A flops

[villains_hero]

In the Mid-NL-Forum there is a nice post about the value of KK when an A flops and what to do in these spots. The main thing I remember is that a flop bet in many cases isnt useful because worse hands won't call. So, did I play this one correctly?

NL 2/4 6-handed

Villain is like 40/10/1,2, not bluffy, paying for too many showdowns (the same villain as in the other post I made in this forum).

Hero ($368) in the SB with K[img]/images/graemlins/spade.gif[/img] K[img]/images/graemlins/heart.gif[/img]

Button ( $504.91 ) opens $16, Hero raises $46, BB folds, Button calls.
