1NT Opening point ranges - Comment|
The most commonly used 1NT Opening bids fall within the range of 10 -
18 HCP :
Ron Klinger (in his book 'The Power System', Modern Bridge
Publications, 1993) categorically states that :
"As far as the object of the
bidding is to locate the best contract for your partnership
ALL (above) NO-TRUMP RANGES ARE
He makes the following points.
- All above NT ranges are fine as a sound basis for finding a Game
or Slam contract, but their weakness lies in finding the best
The weaker the no-trump, the more often
the partnership will land in the wrong partscore!
- Weak 1NT Openings (in the 10-15 HCP range), although good in
terms of pre-emptive value and damaging to the Opponents, are
commonly doubled for penalties, which opposite a weak partner
can cost the side dearly.
- If you are lucky enough to be left in a 1NT contract (regardless
the 1NT HCP range) you will statistically on average receive a
65% Match points score (which is of course very good).
Therefore Enemy interference over a 1NT Opening bid is fierce and
supported by more Bidding Conventions than for any other purpose :
Astro (three varieties) - Becker -
Brozel - Canapé - Cappelletti - DONT - Landy - Ripstra - RCOs
- The agony of the 19-20 (or 18-20) points balanced
Such strong hands are commonly opened with 1♣ or
1♦, then passed all around (when Partner's hand is 5 points or less),
resulting in a poor score.
The alternative opening at the 2 level
is too high opposite a Partner with a very weak hand and commonly
attracts a minus score.
Klinger therefore recommends the Power 1NT
Opening with 17-20 points :
After more than 20 years of experience and success both
Nationally and Internationally with this Opening (as part of his
Power System) Klinger reports the following advantages :
- A good partscore contract is easily achieved as
Partner ALWAYS replies with 6 or a good 5 points hand.
- Over 20 years of use the Power 1NT Opening has proved to
be 95% Enemy interference FREE.
- When left in 1NT after three passes, the contract is invariably
superior to a miserable 1♣ or 1♦.
