Multi 2 ♦ is offering some benefits during the bidding :
- Most of the time, the contract is played by the strong hand , protecting tenaces and making the defenders' job more difficult.
- it leaves space for 2 ♥ or 2 ♠
- It is possible to look for a game but stop at level 3
- it makes the defense difficult.. the opponents don't know what the opener's suit is!

- 2 ♥ response It's the weakest response : the responder wishes to stop there if the opener holds a weak 2 ♥ opening hand. Technically, every time the responder has no fit in any of the major suits, he will bid 2 ♥.
- 2 ♠ response Stop there if the opener holds a weak 2 ♠ opening hand....but the responder is ok for a 3 ♥ contract if the opener has the ♥.
- 2 NT response relay, forcing for one round without any game ambition (it is similar to the response to a major weak 2 opening). To think of a game, you need a minimum of 15 (or 13-14 HCP well constructed).
