When holding 5-4 in the majors and game-forcing values, one starts with 2♣, Stayman. If opener rebids a major, then a fit has been found; otherwise:
| West | North | East | South | |
|---|---|---|---|---|
| 1NT | Pass | 2♣ | Do you have a 4-card major? | |
| Pass | 2♦ | Pass | ? | No. |
Then responder’s jump to 3 of a major shows 4 cards in the suit bid, 5-cards in the other major and is game-forcing.
| 3♥ | 4 hearts, 5 spades, game force |
| 3♠ | 4 spades, 5 hearts, game force |
