The 2♣ Stayman is a conventionnal bid.
In response to a 1NT opening, a 2
♣ bid is a Stayman, looking for an eight-card fit in a major suit.It promises:
- at least 8 HCP
- and at least 4 cards in one of the majors. It is also used with both majors, 4-4 or 5-4.
Avoid using this convention when you hold a 4333 hand with scattered honors. These hands are too balanced to work well in a trump game. You'd rather play a NT game (9 tricks instead of 10)

♣ Stayman is forcing for one round, indeed !
