Nilsland Defense

Nilslandske slinkningar is a defense against doubles after 1NT, made by the Swedish Mats Nilsland. This can be used after a 1NT opening has been doubled or 1NT overcall has been doubled. The only drawback with this convention is that you never can play 1NT doubled.
A. A direct bid at the 2-level.
If the partner to the NT-bidder bids directly a suit at the two level, it
shows the suit + the suit above.

W N E S
- 1NT X 2C : C + D .
2D : D + H .
2H : H + S .
2S : S + C .

B. Redouble.
If the partner to the NT-bidder, make a redouble, it shows an undefined suit with at least 5 card. The NT-bidder must then bid 2C if the opponents bid pass.

		2. You want to play 1NT redouble.

		3. An unballanced invitational hand with at least 5 card major suit.

		4. An unballanced invitational hand. (is unsure if 1NT can be made)

		5. An unballanced hand, 6+minor suit with two top honours.
