Theory and Conventions

Opponents open  a single-suited weak two

This page assumes that your opponents’ opening bid is single-suited, (or at least fails to promise a second suit).  Such hands will usually be based on a six-card or longer suit, but it might be possible for them to be five-card on occasion.

Two-suited weak twos are also to be met fairly commonly but I shall deal with them on a separate page.

May I remind you of the principle from the previous page that any bid over your opponents’ weak opening suggests opening values, or thereabouts.  It follows that a jump in a suit must suggest a stronger hand in terms of playing strength than a simple overcall.

This is not the scenario for the weak jump-overcall.

Different authorities will suggest different meanings for each and every one of the available bids.

Each of the following possibilities is to be found in one respectable source or another:-

double - for take-out;

double - for penalties;

2NT     - natural;

2NT     - an artificial and limited take-out device;

the opponents’ suit - powerhouse game-force;

the opponents’ suit - strong two-suited;

the opponents’ suit - search for a stop or partial stop for a no trump contract;

three of a minor - natural and forcing;

three of a minor - natural and non-forcing;

three of a minor - an artificial and limited take-out device;

three of a major - natural and forcing;

three of a major - natural and non-forcing.

I have made a selection from the above:-

a basic selection

- it covers ‘overcalling in no trumps’, ‘suit overcalls’, ‘double’ and ‘the immediate cue-bid’.

My choices in this selection probably represent the most common usage.

Whether or not that is the case they are certainly relatively straightforward and perfectly effective.

Following that I shall look at various

extensions and variations

Some of these you might wish to take on board, or at least consider, at a fairly early stage as you progress towards an intermediate standard.
