I played this hand with MickyB. We have rarely played together, but often played against eachother so we had some idea of what we were doing.
The auction raises some questions..
1) Is south good enough for 3NT?
2) How would you play 4D in your partnership? Clearly we had no agreement, South thought it might be a transfer, North thought it might be both majors.
3) What would your auction have been.
The play is also somewhat interesting. What contract would you like to be in? How would you play 6H after a diamond to the ace and a club back? (if it matters, the opponents are good)
I don't remember the vulnerability.. does anybody? My guess is nobody vul, so assume that.
