Transfer Conventions
Developed in order to prevent the strong hand to be dummy in NoTrump opennings.
Jacoby Transfer : Developed by Oswald Jacoby (1956). In Notrump opennings, the responder bids 2 Diamonds if he has at least 5 cards of Hearts. The opener should transfer this to 2 Hearts. The procedure is the same for Spades, responder bids 2 Hearts and opener transfer it to 2 Spades. This convention does not require any points because it is better to play a long suit with even zero point instead of NoTrump. As an extension of this convention Minor suit transfers require at least 6 cards. There are some different applications for minor suit transfers.
- The players who play Minor-Suit Stayman bids 2 NT for transfer to Clubs, and 3 Clubs for transfer to Diamonds.
- In Super Five Cards Major transfer to Clubs is done with 2 Spades, transfer to Diamonds is done with 3 Clubs.
- The other systems bid 2 Spades for both minor transfers. Opener tarnsfer it to Clubs and the responder bids the Diamonds if it is the case.
Texas Transfer : Developed by David Carter from US and Olne Willner from Sweden independently from each other. If the responder has sufficient value for game and at least 6 cards of a major, he applies the transfer at the 4th level, bids 4 Diamonds for 4 Hearts, 4 Hearts for 4 Spades.
Smolen Transfer : Developed by Michael Smolen in order to show 5-4 major distribution when the answer to Stayman is 2 Diamonds. Responder bids jumping his 4 cards major if he has game points, Opener understand that the other major is 5 cards, then he bid game from that major if he has 3 cards, otherwise bids 3 NT. With invitation points responder would bid his 5 cards major without jumping.

Mitchell Transfer : Developed by Victor Mitchell but known as NAMYATS. This convention is applied with hands strong for 4 major opennings, but weak for 2 Clubs opennings. You must have solid 7 cards of a major, 4 Clubs openning shows Hearts, 4 Diamonds openning shows Spades.
If responder does not have slam interest bid the game. The response other than the indicated major shows slam interest and asks the unconrolled suit. 4 NT is Blackwood Convention.
