Multi 2 Diamonds recommended by Kit
The multi 2 ♦ presents several advantages in partnership bidding :
The multi 2 ♦ bid discussed here only covers hands that would 'normally' have been opened with a 2 weak Major qui auraient été ouvertes d'un 2 majeure faibles.
- The contract is almost played by the strong hand , which protects isolated honors and makes defense more difficult.
- It frees the 2 ♥ and 2 ♠ bids to be used for other purposes
- it makes it possible to explore game and stop at the 3 level 3
- it makes the opps' defense more difficult...as they are not sure about the opener's suit

Responses to Multi 2 ♦
In the simple version proposed here, the opening bid of 2 ♦ is not forcing...with no fit or hope for game and with a long ♦ you could very well pass!
2 ♥ and 2 ♠ paradoxal responses, and 2 NT is forcing
The responder starts by bidding his weakest Major, and the opener passes or rectifies

- The 2 ♥ response is the weakest : the responder wants to leave it there if the opener had a 2 weak ♥ opening. In practice, it is negative for ♥. Every time the responder knows he is not fitted in your Major he bids 2 ♥. The opener then passes or rectifies at 2 ♠.
- The 2 ♠ response shows a willingness to leave it there if the opener had a 2 weak ♠ ....and that he is ready to plat at the 3 ♥ level if the opener's weak Major was ♥ . The opener passes or rectifies to 3 ♥
- The 2 NT answer is a relay forcing forcing for one round and with hopes for game : it corresponds to the 2 NT answer to a 'normal' 2 weak Major. For a game to be possible, he needs to have a of 15HCP, (or 13-14 with extra shape values).
