Sitting South, opposite Azamali24, the opening bidder, vulnerable, I had a very powerful hand (23 high card points). When my partner opened 1NT I was amazed - his minimum 15 pts+my 23=38. So, naturally, I did a sextuple jump to 7NT. Between us, we had all aces, kings, queens, half the jacks and all 6 top diamonds, giving us enough winners for 16 tricks!
When East doubled (on the basis of a less than powerful hand - 1 pt, but a nice long
♣ suit - errm, headed by the 10 - I'm sure it seemed a good idea at the time

), I redoubled, and we went on to make what I think is the max score, 2980 pts. I've been at 7NT vul before, but never expect again to be there redoubled, since it's doubtful anybody would do so without an ace, or possibly a king.
What was somewhat strange was that my partner didn't claim, although perhaps he wanted the pleasure of laying out 13 tricks.
Does anybody know how frequently this score is attained?
