PLaying a tournament with a good one-time partner I got stuck in this position:
Before starting the day we had agreed on playing Ghesthem, where the 3♣-bid denotes at least 5-5 in spades / diamonds. I alerted this and explained our agreement when asked. As she bid 6♣ I of course "knew" (or rather suspected seriously) that partner had made a mistake and was holding long clubs. However, I thought that I could not (yet) draw that conclusion from just the 6♣-bid.
What are my (ethical?) options here?
Made this a general poll because i am most interested in comments on my ethical obligations.
