If my partner had bid her 10 high-card points preemptively, I might have at least leapt us into a spades slam. But I went for good old 6NT again.

This one was pretty straightforward after the dummy came down. Lost the first club trick, won the second club trick, crossed over to partner's lovely spades and cashed the lot, discarding three hearts and two diamonds. In lieu of finessing, I then inelegantly played my top red-suit winners, diamond diamond heart, and the winning queen of diamonds happily fell on the ace of hearts, both opponents opting to guard the club suit instead. My jack was a winner and the slam was good. Did I learn my lesson? Not quite yet.
