You are playing a bracket 1 knockout, opponents are world-class, though not necessarily regular partners (Hampson/Cheek). You have not discussed delayed interference over stayman, but given your other agreements, X by you is likely to be played as a strict penalty double by partner, who is an expert. You have not shown any values with 2♣, as that is frequently garbage stayman.
What do you do now?
Edit: In case it is not clear from the diagram, the NT opening is 12-14.
