2♥︎5♠︎4♥︎ or 55, to play → 2NT is an invitation in a major, 3M = PRE
2♠︎Balanced INV or the minors (2NT = I don't accept; 3♣︎/3♦︎ = I accept and choose the minor); then the first step is 55 up to 15-16 points with a shortage in the low major, the second in the high major, and the third, if there is room, is "you bid NT".

- 2OM always shows 5+M and is GF
- Then 2NT always promises a fit and requires a 3♣︎ relay, to which we answer: low length, high length, extra diamonds, (03)55.
- The next step that is not 2NT shows a shortage in the major and a maximum hand. It requires a new next-step relay, to which we answer: low length, high length, extra diamonds.
- The next 3 steps are 55 with low/high, extra diamonds, extra clubs
