At all vuln, you are dealer and pick up:
♠x
♥Txx
♦Txx
♣QJT97x
Your pard is an intermediate player who you only play once in a while, so you didn't get into details about vulnerable preempts. Pard's not used to off-the-record tactical bids, but he's not the sort of person who'll play you for the world when you open a vuln 3C. You gaze into your opponents, who are solid bidders with 20+ years experience, but can't find any visible signs of bidding ache.
Under these conditions, do you open 3C?
