I first thought to bid 7 after finding out that partner had the ace of diamonds, but I chickened out and bid six. Good thing too, because partner misplayed the hand (he didn't see the crossruff) and made only 6. At matchpoints, most other tables were at aix clubs making seven. NOBODY bid the grand. Thoughts?
