Hi,

I seem to have missed something.

Strange rebid description

My 3NT rebid may be questionable, but this is our last chance to reach 3NT. I was gambling that either my diamonds or GIBs clubs run, and that we have 9 quick winners. GIB jumped to slam. Not a hopeless slam on a spade lead, but at my table the GIB correctly hanged on to its diamonds, and I only made 11 tricks. GIBs jump is a bit frisky (a fair shot?). My question revolves around the description of the 3NT rebid, because a closer examination reveals that
GIB thinks I promised 17 TPs. This baffles me. The opps have bid up to 3S. I have a spade stopper, GIB most likely does not. Why would 3NT promise anything else but a spade stopper in a minimumish hand?

Mind you. I should have made the slam. East is under tremendous pressure when the clubs are run, and came down to the singleton HA and DQTxx. If only I had kept the heart spots and discarded the fourth diamond, when it became apparent that East is hanging on to a diamond stopper. After clubs exit with a heart to the bare ace, win 3 diamond tricks on the enforced D-return and cash the HK for the slam-going trick. Instead I was hoping for the diamonds to run, too, and hoped to score an overtrick ;-)

6NT-1 was worth 77%

I agree, that seems wrong. It seems to be based on the old fashioned idea about free bids showing extra. Although it doesn't think so if you rebid 4♦, that just shows a twice rebiddable suit.
