So, if you are ready to try the full system after 1NT (Double)...

• Redouble = Transfer to 2§ (long Clubs)

OR if responder bids 2¨, shows 3 suited hand, short in § (5440 shape or 4441 shape)

OR if responder bids 2©, shows both majors with longer © than ª, 45xx style

• 2§ = Transfer to 2¨ (long Diamonds)

OR if responder bids 2©, shows both majors with longer ª than ©, 54xx style

• 2¨ = Transfer to 2© (long Hearts) - simple !
• 2© = Transfer to 2ª (long Spades) - simple !
• 2ª = Two suits 5/5, Spades and another
• 2NT = Two suits 5/5 but NOT not Spades.

• Pass forces a redouble from opener.

Responder can pass this (to play 1NT redoubled!) 

Or if responder bids 2§, shows Clubs and another suit (4 /4 );

Or if responder bids 2¨, shows Diamonds and either Major (4 /4 );

Or if responder bids 2©, shows both Majors, equal length (4 /4 );

Note that after :

1NT (Pass) Pass (Double)

Pass (Pass) [here…]

Halmic now still applies

• Pass is now to play 1NT doubled !
• 2§ = Clubs and another suit (4 /4 );
• 2¨ = Diamonds and either Major (4 /4 );
• 2© = Both Majors, equal length (4 /4 );
• 2 = 5/5, Spades & another;
• 2NT = 5/5 not Spades

The whole basis of this system is Pass or Correct style.  It is designed to get out of 1NT doubled into a safe place to play where the opponents may not be able to double you or double you into a making game !

.

Remember, it's all about bidding with SHAPE and few points - with lots of points get to play in 1NT redoubled if you can.

If you take this up you will do well.     I play it;  ask me anytime - Barry :-)
