Overpair - Check min-raised on flop

[Soul Daddy]

I'm about 1 orbit in, so no real reads. Villain has done nothing noteworthy thus far.

Party Poker No-Limit Hold'em, $0.5 BB (10 handed) converter

UTG+1 ($43.75)
UTG+2 ($13.06)
MP1 ($54.5)
MP2 ($83.43)
MP3 ($43.9)
CO ($46.05)
Button ($23.5)
SB ($55.86)
BB ($57)
Hero ($59.65)

Preflop: Hero is UTG with K[img]/images/graemlins/club.gif[/img], K[img]/images/graemlins/diamond.gif[/img].
<font color="#CC3333">Hero raises to $2</font>, <font color="#666666">4 folds</font>, MP3 calls $2, <font color="#666666">3 folds</font>, BB calls $1.50.

Flop: ($6.25) 7[img]/images/graemlins/club.gif[/img], 6[img]/images/graemlins/club.gif[/img], 9[img]/images/graemlins/spade.gif[/img] <font color="#0000FF">(3 players)</font>
BB checks, <font color="#CC3333">Hero bets $4</font>, MP3 folds, <font color="#CC3333">BB raises to $8</font>

Hmm... The check and min-raise. Looks like a way ahead/way behind situation to me. Anyone disagree?

my normal line would be to call but lately I've been advised to reraise to 16 to 20.
