NL100: Top two on drawy board

[guess who]

Hi 2+2,

I have no stats on villian but we have had some hands together. He likes to call my bets and also likes to bet out big when I seem to be weak.

CO: $20.50
Hero: $152.30
SB: $96.35

Pre-flop: (6 players) Hero is Button with K[img]/images/graemlins/heart.gif[/img] 6[img]/images/graemlins/heart.gif[/img]
3 folds, <font color="#cc0000">Hero raises to $4</font>, SB calls, BB folds.

Flop: 5[img]/images/graemlins/spade.gif[/img] K[img]/images/graemlins/club.gif[/img] 6[img]/images/graemlins/spade.gif[/img] ($9, 2 players)
SB checks, <font color="#cc0000">Hero bets $6</font>, SB calls.

Turn: 3[img]/images/graemlins/diamond.gif[/img] ($21, 2 players)
SB checks, <font color="#cc0000">Hero bets $15</font>, <font color="#cc0000">SB raises to $54</font>

I raise K6s OTB which is ok I think. My flop bet is to small, can't remember what I tried to achieve with it.
On what range do you put SB here? Do you go broke here with top two?
