Poker Stars AA v. KK hand for Review

[12AX7]

OK, This is a case of "I got rivered by a two outer".

But did I play it wrong?

I limped in hopes of trapping...then...

After getting my check raise re-raised at the flop I was actually seeing trips at that point and backed off.

I don't think anything I could've done would've folded the KK's... But what do you think?

Should I have steamed ahead, or was throttling back an OK thing to do?

What of limping with AA?
