12 HCP - 3 NT

12 HCP - Staymen.  2 4 card Majors.

Looking for a fit in the majors.  Enough for game.

Staymen 16 HCP and 4 Spades.  Might see Slam in the future in Spades.Slam in NT highly unlikely.

Pass - Only 6 HCP

2 C - Staymen

3  NT

4-3-3-3 Hand so don't use Stayman.  No "ruffing" value.

2 NT.  No a great hand but tell you partner what you have.  Why not bid your Diamonds?  We will get into that at a later time.  You need 6 since your partner only promises 2 of each suit.

Pass.  Only 2 HCP
