After a very enjoyable dinner prepared by our hostess, we sat down to play two 12-board matches scored at IMPs converted to VPs. The first board of the match often sets the tone for the evening, and so it was with this one.
The 6♦ bid was made after long thought.
1. Do you agree with the double on the first round?
2. What do you do over 6♦?
