FWIW, I liked my hand and decided to explore game with 3♦, presuming no conventional game tries would apply in such a tournament. LHO (with a large number attached to his profile) asked for an explanation. I replied "no agreement". He persisted with "you must explain if asked". I was taken aback by this follow-up, but replied "natural", at which point he summoned the TD. After the hand LHO said that we self-alert here.
My questions are:
- Did I need to alert 3♦?
- Was my "no agreement" response insufficient?
- Should I have even answered the follow-up?
- Was my LHO reasonable, including calling the TD?
Thanks!
