Theory and Conventions



The basic wriggle

This differs only in detail from the common-sense approach outlined on the previous page.


The immediate redouble is now given an alternative interpretation.  Typically it will carry the message ‘I have a five-card suit’.  Partner is asked to bid 2 after which you will either pass or correct.

The forcing pass

The natural meaning of the redouble is replaced by the introduction of ‘a forcing pass’, requiring partner to reopen with a redouble. Following this redouble you will either pass when holding some values (say 8+ points as before) or start bidding four-card suits up the line as you search for an escape.

Redouble, promising a five-card suit.

Partner will bid 2, and you will correct to 2.

To be honest, this method in itself is no more than marginally better (at best) than the common sense approach.

It caters for the same hand-types with more or less equal effectiveness.

The advantages are that it familiarises you with the ‘forcing pass’ which is integral to virtually all of the more advanced methods, and it also creates additional bidding space.  The immediate suit bids by responder become available, although they are not utilised in the limited method outlined above - this will be the principal extension as we come to extended wriggles.

Use this method as a stepping stone.

Get used to the forcing pass and the artificial redouble as defined here,

then move on to one of the extended systems which follow.
