opening and folding to a cap?

[kimchi]

This hand gave me nightmares because of what happened on subsequent streets, but:

$2/4 6 handed
I raise T [img]/images/graemlins/spade.gif[/img]T [img]/images/graemlins/diamond.gif[/img] UTG
it's folded to CO (50/15/1/5 type) who re-raises.
Folded to BB (TAG regular, but with PFR% around 11) who caps
I fold.

What hands are correct to fold for a cap and in what situations? I've been in this situation several times recently in aggro games facing a cap in the BB are after raising with hands like QJs, AJs and not happy folding or calling.

JJ+ and AQs+ (sometimes KQs and AJs with position) I'm capping.

Where/in what situations will you find folds if you open raise in early position and it's capped back to you?
