KK 3-way capped pot. Ace flops. Your plan?

[SomethingClever]

I open K[img]/images/graemlins/heart.gif[/img] K[img]/images/graemlins/club.gif[/img] UTG, folded to SB (60/15 donk) who calls, unknown BB makes it 3, I make it 4, SB obv calls.

Flop: A[img]/images/graemlins/diamond.gif[/img] 2[img]/images/graemlins/heart.gif[/img] 9[img]/images/graemlins/heart.gif[/img] (12 SB)

SB leads, BB folds, Hero... calls down?

Further question: If I peel the flop, I obviously call any [img]/images/graemlins/heart.gif[/img] turn. Does anyone peel the flop and fold any non[img]/images/graemlins/heart.gif[/img] or non K turn?

Or is calling all the way down best?
