KK OOP $20nL

[MicroDonk666]

Sorry about the lack of decent hand history but no poker tracker yet and my site has weird hh's

New to table only played one hand, haven't really played much with anyone at the table so no reads.

Dealt K[img]/images/graemlins/spade.gif[/img]K[img]/images/graemlins/club.gif[/img]in the sb($20.70) folded around to CO who limps, button folds, I make it $0.80 BB folds and CO($15.67) calls...

flop: 6[img]/images/graemlins/heart.gif[/img]Q[img]/images/graemlins/heart.gif[/img]A[img]/images/graemlins/spade.gif[/img]($1.80)

I lead out with a half pot bet of $0.90 which results in an instapush from the CO

call or fold? what hands are u likely to see here aside from from AK[img]/images/graemlins/heart.gif[/img] and AQo? Am I ever ahead here?
