Sorry guys no stats on villain. I guess I'm more interested in what people's usual thinking is when they get an overcard to their nice pp on the turn or river.

PokerStars No-Limit Hold'em, $0.02 BB (8 handed) - Poker-Stars Converter Tool from FlopTurnRiver.com

SB ($4.25)
Hero (BB) ($2.50)

Button ($1.71)

Preflop: Hero is BB with Q, Q
3 folds, Villain calls $0.02, 1 fold, Button calls $0.02, 1 fold, Hero raises to $0.12, Villain calls $0.10, 1 fold

Flop: ($0.27) 8, 10, 6 (2 players)
Hero bets $0.20, Villain calls $0.20

Turn: ($0.67) K (2 players)
Hero checks, Villain bets $0.30

Hero?

I'm a little torn here. I can't decide whether:

a) He's called made a poor call on the flop with Kx hoping to get lucky and has...

or

b) He's drawing to the club flush (which makes sense of his call on the flop), he sees the K and takes my check as a sign of weakness.

or

c) Neither of the above.

Should I have bet the turn?

Any help very much appreciated.
