אנו שמחים לפרסם את הכתבה השנייה (מתוך 5) בנושא " הערכת היד – הכרזת סדרות ה-minor" (המקור: mrbridge).
בדרך כלל הידיים שבהן חוזה בסדרת minor עדיף על חוזה NT הם אלה שבהם אתה מחזיק חלוקה קיצונית עם פחות HCP -נקודות קלפים גבוהים . ככל שאתה מחזיק יותר HCP , כך סביר יותר הוא שחוזה NT הולך להיות מתאים יותר. עם זאת, אם יש לך יד חלוקתית ועוצמת HCP , ואז slam ייתכן בקלפים אלו. שוב, הדרך הטובה ביותר לשפוט אם slam אפשרי היא להשתמש ב-LTC.
הנה שתי חלוקות נוספות, אבל בהזדמנות זו אלו הן במזרח הידיים הזהות:
הכתבה היא בשפת המקור=אנגלית. בהמשך אעלה את התרגום בעברית וכתבות נוספות.

HAND EVALUATION 28
Part 2 of 5
by Bernard Magee
Here are two more layouts, but on this occasion it is the East hands that are the same:
In Layouts 3 and 4, both Wests open 1 and hear a 1 response and then, with good distribution and first-class support, both Wests use the LTC to decide on their rebid. With 6 losers each, both make a jump response to 3. East is not so keen on a diamond contract, because he is balanced and would much prefer playing in no-trumps. However, he needs a spade stop, so he makes a game try by bidding 3: he is saying that he has strength in hearts and thus that the partnership has a weakness in spades (all the other suits have been bid).
In Layout 3, West has no strength in spades and therefore avoids no-trumps. He rebids his clubs to emphasise their strength and over 4 he bids on: his spade singleton is likely to be valuable. His 4 bid is sensible: East might have four hearts after all, which might make 4 a good game, but East subsides in 5 - happy to have found the best game.
In Layout 4, West has the stopper in spades which East desires and he therefore bids 3NT which ends the auction. 3NT is certainly not a perfect contract, but it is the best contract.
There will be hands when there is no doubt that a minor-suit contract is desirable; this happens when both players have distributional hands:
West opens the higher-ranking of his two touching five-card suits: 1. East has only five points and so could choose to pass, but, with two five-card suits and only a singleton in partner's suit, he does best to respond 1. Now things take a turn for the better when West rebids 2. East can count his losers and from holding a sub-minimum hand he suddenly has 8 losers, which is one better than the minimum (minimum responder = 9 losers). So, instead of passing, East should raise his partner to 3. Now West, too, considers a diamond contract; he counts his losers and finds he has just 5! That is two better than opener's minimum, so he bids two more – on to game. With big fits, lots of tricks can be made; here with just 19 points 5 should be straightforward, extra tricks coming from cross-ruffing.
Both East and West had very distributional hands and both used the LTC to gauge the strength of their hand. Generally the hands where a minor suit contract is better than a no-trump contract are those where you hold extreme distribution with fewer high-card points – the more high-card points you hold, the more likely it is that a no-trump contract is going to be more suitable. However, if you have distribution and high-card-point strength, then a slam might be on the cards. Once again the best way of judging whether a slam might be on is to use the LTC.
