Since everyone plays Stayman, people take it for granted and forget to discuss. What happens if you find a fit and want to try for slam.

Suppose you hold today's North hand. You would like to investigate a slam in spades, but if partner holds weak trumps, or if you are off the first two club tricks, you don't want to go past the four level. How can you find out this information?

Other Major Slam Try after Stayman

After partner answers Stayman with a major-suit response, responder bids THE OTHER MAJOR AT THE THREE LEVEL to show support of opener's major with a slam try.

Opener	Responder
1NT	2
2	3	slam try in hearts
1NT	2
2	3	slam try in spades
2NT	3
3	3	slam try in hearts
2NT	3
3	4	slam try in spades

In the fourth example, responder was unable to bid the other major at the three-level, so he must bid 4. This leaves very little room for investigating, but it is better than nothing and is consistent with the other three auctions.

After three cuebids, the auction comes to a halt in 4, each player having shown slam interest. Without anything extra, neither player goes past 4. It was a delicate auction, with the help of today's convention.
