KQs 3bet in SB, bet, bet, all-in with top 2 - ok?

[Psydoc]

Anyone have a problem with the way I played this?
No good reads at the time, although villain later appeared to be a fairly tough aggressive player.

Holdem No Limit - $2 BB

UTG ($158.75)
CO ($89.25)
Button ($348.25)
SB ($269.50) [Hero]
BB ($190.75)

Hero is SB with K[img]/images/graemlins/heart.gif[/img], Q[img]/images/graemlins/heart.gif[/img]
Preflop: (4 players, $3)
UTG folds, Button calls $2 and raises $8, Hero calls $9 and raises $20, BB folds, Button calls $20

Flop: 5[img]/images/graemlins/heart.gif[/img], K[img]/images/graemlins/club.gif[/img], 3[img]/images/graemlins/spade.gif[/img] (2 players, $62)
Hero bets $45, Button calls $45

Turn: Q[img]/images/graemlins/spade.gif[/img] (2 players, $152)
Hero bets $101, Button calls $101

River: 6[img]/images/graemlins/club.gif[/img] (2 players, $354)
Hero bets $93.50 and is All-In, Button calls $93.50

I like a flop check here, but after you make top two, I think its worth it trying to get all in because there are more AAs and AK(s) than KKs and QQs left, and because he might think you are full of it and call with something really stupid..

I may or may not check this flop

Obv once that turn comes you want all the money in
