??? Yes, I realize 7N with 13 top tricks is better. At what point can West count 13 tricks? At what point does West ask for aces- over 2♣ or over 6♠? We don't have a way to ask for the K♠.

[hv=pc=n&s=sakht43djcaqjt965&n=sqj985hkqj8datck7&d=e&v=b&b=10&a=p1cp1sp3cp]266|200[/hv] What next? North knows we have slam values but how can she determine if they're in the right places? Would 4♣ be forcing?

Winstonm hit the nail on the head! Partner and I don't have any "sophisticated" agreements- that's why I keep posting here :) She went into the tank and eventually bid 6♠. Since she didn't ask for aces, I was SURE we had all four (yep, no Key Card). The K♠ was still a mystery but I felt I had extras and bid 7. The four hands: [hv=pc=n&s=s2hdk9863cqjt8432&w=sqjt764hkqj9d7ck6&n=s9853h87654dtc975&e=sakhat32daqj542ca&d=e&v=0&b=14&a=2cp2sp6sp7sppp]399|300[/hv] Fortunately for us, North led his stiff ♦ rather than a safe ♥.

The complete E/W hands: [hv=pc=n&w=sqjt764hkqj9d7ck6&e=sakhat32daqj542ca&d=e&v=0&b=14&a=2cp2sp]266|200[/hv] At the table, West chose 2♠. Up to you, East.

I apologize to all who responded to the initial question. This is the corrected version. Thanks to gnasher for pointing out my error! IMPs. [hv=pc=n&w=sqjt764hkqj9d7ck6&d=e&v=0&b=14&a=2cp]133|200[/hv] What is West's call?

Thanks for the many responses. At the table, West chose 2♠. [hv=pc=n&w=sqjt764hkqj9d7ck6&e=sakhat32daqj542ca&d=e&v=0&b=14&a=2cp2sp]266|200[/hv] Up to you, East.

IMPs. [hv=pc=n&w=sqt9764hkqj9d7ck6&d=e&v=0&b=14&a=2cp]133|200[/hv] How does the auction proceed? Once upon a time, West would respond 2♠ showing 8+ HCP and 5+ spades.

Thank you, especially for the link! I also thought that 2H was a better rebid by West based on East's guarantee of a rebid, but "blame partner" is the easy way out. :P Looking at the ACBL pdf, it seems that the "proper" sequence is 1♦-3N (16-17)-6N (19 + 16/17 = 35/36) Clean, defined, and no improvising. Thank you very much! :D

Then let me ask "How does West show a balanced 19 after 1♦-2♣?" and "How does East show a balanced 16 after partner opens 1♦?" Thank you for your sarcasm. B-) "He was so stupid, he couldn't count to 21 unless he were naked."

BBO's interactive SAYC convention card seems to refute these auctions. 2N Only if you upgrade West. 1♦-2♣-3N This was the actual auction. As East, I took 3N to show a sound but minimum opener, leaving us a bit short of 6N. BBO SAYC describes 3N as "signoff". 1♦-3N 13-15 Undervaluing the East hand works here. But what bid if East is stronger- ♣AKQx? Thank you for your reply. :)

BBO's interactive SAYC convention card says that 3NT shows 13-15. This would have gotten us to 6 despite undervaluing East's hand. The hands are close to 7NT but no one would be tempted after 1♦ 3NT. If East were stronger- ♣AKQx, then what auction? Thanks for your reply. :)

South deals. N/S pass throughout. [hv=pc=n&w=sak4haj87dak94ct2&e=sq63hkq6dq87cak86]266|100[/hv] What SAYC auction gets to 6NT?
