MULTI


Multi is an opening system to show weak 2 in a major suit or a strong NT(20-21 / 22-24). 
This convention come in loads of different variations, but here I'm going to list some version I have used. 

In addition to weak 2 and strong NT, you can use multi as either of the following:

(1) A minor suit and game forcing without side suit. The sequence 2C-2D-3C/3D will then promise a side suit, and the suit above is used to ask which.

(2) Strong 4441. The suit above is Relay after numbers of controls (Ace=2 , King=1)
1 Step: 4-6 Controls , 2 Steps: 7 Controls.....
After the response of 1 Step, you can relay after the exact numbers of controls.
