Key questions and guiding principles
The following general guidelines to good bidding, and specific questions and answers relating to my recommended methods, are taken from the pages on bidding and are collected together here for quick reference.
Can I open 1NT with a singleton?
I prefer not to, but it is an option subject to partnership agreement, in which case partner must announce the possibility each time.
When do I open 1NT on a balanced 12-
Can I open 1NT with an unstopped suit?
Yes, or even two unstopped suits if the shape is right.
Can I pass with a twelve-
Yes. The fact that you play a 12-
Think twice about opening a poor twelve points except in first seat.
Does an opening 2NT always show 20-
No. This is a matter for partnership agreement.

You may as a partnership choose your own range within certain broad limits.
Which suit should I open with a 4-

A secondary aim, if bidding space permits, is to give some indication of the strength of the hand.
Can I open 1NT on a 12-
Yes, if it has 5-
I prefer to open 5-

Most partnerships will agree one.
The suit should be headed by at least KT or QJ, at least in first or second seats.

Can a weak three-
Not in first or second seats, but you might consider it in third.
Can I open a weak three-

This method is not universal, but it is common in expert circles.
How strong is a take-
From about eleven points with appropriate shape, or any hand of seventeen points (or seven playing tricks) or more.
How strong should I be to open one of a suit in third seat?
You can reduce your strength by two or three points when not vulnerable.
The principle that
‘whatever you choose to open you should have a suitable rebid in mind facing partner’s lowest level change of suit’
overrides all other considerations in determining your best opening bid.
What do I do when my partner starts with a weak bid and I hold a weak hand with a void in his suit and an eight-
