Woodson Two-way NT

1NT opening shows either a balanced 10-12 or a balanced 16-18.

Responder bids 2Club to ask and opener rebids:

Responder can then bid 3Diamond to ask for a four card major.

Other responses of 2Diamond, 2Heart and 2Spade are signoff-- even opposite a strong NT opening.

If 1NT is doubled, opener redoubles to show the strong hand.
