2/4: 170bbs deep, 4-bet pot, TPTK... c/f?

[Michaelson]

Opponent's a regular TAG. No notable history. I have been playing pretty straight up TAG, but anyone who has stats on me from when I last played 2/4 a few months ago would have me pegged as a LAGtard, 28/22 or thereabouts.

Do I just check fold this flop? I can't see his range being much broader than QQ+, AK.
