הערכת היד-הכרזת סדרות ה-minor – כתבה ראשונה (אנגלית) מאת גבי לוי

פורסם בתאריך 11/01/2012.

אנו שמחים לפרסם את הכתבה הראשונה (מתוך 5)  בנושא " הערכת היד – הכרזת סדרות ה-minor"   (המקור: mrbridge).

התאמה בסדרות ה-minor שונה מאוד מהתאמה בסדרות ה-Major. כאשר יש לנו התאמה ב-Major אנחנוכמעט תמיד נשחק בסדרת ה-Major, אבל עם התאמה ב- minor, אנו נוטים לחפש חוזה ב-NT. הסיבה לכך היא שלחוזה משחק מלא ב-NT צריך רק תשע לקיחות, בעוד שמשחק מלא בסדרת minor דורש אחת עשרה.

הכתבה היא בשפת המקור=אנגלית. בהמשך אעלה את התרגום בעברית וכתבות נוספות.

HAND EVALUATION 27

Minor-Suit Bidding
Part 1 of 5
by Bernard Magee

Minor-suit fits are very different to major-suit fits. When we have a fit in a major we almost always play in the major suit, but with a fit in a minor, we tend to look for no-trumps. This is because a no-trump game needs just nine tricks, while a minor-suit game requires eleven. This is especially true at Duplicate Pairs when the extra points scored in no-trumps make a big difference. However, it is important to know that the minor suit is solid and running, offering a quick source of tricks. You will notice that in the first few examples below, when there is a solid suit, 3NT makes an excellent contract, but when the suit does not run, you do best to stick to a suit contract. The Losing Trick Count can still be used with minor suits, but only when you have decided that you will play in a minor – quite often this will be with highly distributional hands.

There are two different types of hand that I would like to look at:

1. Hands with a minor-suit fit.
2. Hands with a long minor suit.

MINOR-SUIT FITS

On a large number of occasions when you find a minor-suit fit, you will lean towards playing in a no-trump contract, but sometimes you need to check that you can stop all the suits. For example:

The West hands in Layouts 1 and 2 are the same: they open 1 and, when they hear their partner bid 3 , they know that a game contract should be comfortable – but which one? With such a balanced hand 3NT is the obvious contract, but what about the heart suit?

The jump to 3  denied four cards in either major; East would have responded 1 rather than jumping to 3  if he had had four hearts. A bid of a new suit after jump-support for your first suit is not natural. It is an attempt to improve the contract and, when a minor-suit fit has been found, it is used as a game try for a no-trump contract. Your aim is to make sure that you have all the suits covered, so you bid the lowest suit in which you have strength. Here West rebids 3 and now East shows in which suit he has strength; with stops in both hearts and spades he could bid 3NT.

This is where the two auctions differ: in Layout 1, East shows his heart strength which allows West to bid 3NT with confidence. However, in Layout 2, East rebids 3 and now West knows there is no stop in hearts and therefore 3NT is no good, so he pushes on in clubs; with three losing hearts he bids just 4 . East could pass this, but with a doubleton heart, two kings, an ace and five trumps, he bids on to 5

A bid in a new suit after a minor suit is agreed (early in the auction) shows a stopper in the suit and is generally suggesting the chance of playing in a no-trump contract.

It is important to get into the habit of aiming for no-trump contracts when a minor fit is found. If you can make nine tricks, then +400 for a non-vulnerable 3NT is much better than +110 for 3  or 3.
