bet or check?

[PokerBob]

canterbury 30/60 9 handed
BB hates bicyclekick, which had no bearing on this hand but it cracks me up so i must point it out. He likes to raise the turn when he has position for a free showdown. At times he can get weird/retarded aggressive, but hasn't done anything absurd that i have seen. FWIW i think he hates me too.

The dealer flips up the A [img]/images/graemlins/heart.gif[/img] which now becomes the burn. i look down and K [img]/images/graemlins/club.gif[/img]K [img]/images/graemlins/spade.gif[/img] and smile on the inside and open-raise. folds to BB who 3 bets. i make it 4 and he calls.
