אנו שמחים לפרסם את הכתבה הרביעית מתוך 5- בנושא "הערכת היד – יד טובה-יד גרועה" (המקור: mrbridge).
והפעם, קלפים בסדרת השותף:
- מכובדים בסדרת השותף,
- קוצר בסדרת השותף.
מכובדים מבודדים אינם טובים, אבל אם הם בסדרתו של השותף שלך הם יכולים להיות יקרי ערך – אתה יודע שהם יעבדו עם המכובדים של שותפך לבסס לקיחות. מכובד גבוה בסדרת שותפך שלך הוא בהחלט מאפיין חיובי וניתן למקמו בצד הקטגוריה הטובה.
כאשר יש קוצר בסדרת שותפך, שדרג מטה-downgrade את ידך. בניגוד לכך הוא קוצר בסדרת היריבים. עם קוצר בסדרת היריבים שדרג את ידך.
הכתבה היא בשפת המקור=אנגלית. בהמשך אעלה את התרגום בעברית וכתבות נוספות. לקריאת הכתבה לחצו כאן
HAND EVALUATION 43
Good Hand, Bad Hand
Part 4 of 5
by Bernard Magee
CARDS IN PARTNER'S SUIT
(a) Honours in partner's suit
Isolated honours are not good, but if they are in your partner's suit they can be invaluable – you know that they will work with partner's honours to establish tricks. A high honour in your partner's suit is certainly a positive attribute and would place the hand in the 'good' category.
In Layout 1, West has the ace and queen of hearts working together along with the king of clubs in his partner's suit. All the honours are 'working', which means the hand is 'good', so you should jump to game: even if partner has just 15 points, you expect game to have a good chance. There are eight easy tricks and a ninth is likely to come from South's opening lead.
In Layout 2, West has isolated honours and, with no help in his partner's suit, he has a 'bad' 9 count and should just invite partner to game; unless East has 17 points, game is unlikely to make. East passes 2NT and even that will be a struggle because establishing any suit will be difficult.
(b) Shortage in partner's suit
A singleton is highly valuable, but in partner's suit it loses some of its worth because often it will devalue partner's high cards. With a suit like A-Q-8-7-6 opposite a singleton, you are likely to win the ace and ruff the next round: much of the value of the queen is wasted. However, the point is exacerbated with a suit such as K-J-8-7-6: when this is opposite a singleton, most of the 4 points in the suit could be wasted.
Not only might your partner's high cards be wasted, but it is also harder work to establish tricks from the suit; as I just showed, an honour in partner's suit can make extra tricks much easier to establish, solidifying the suit, but a singleton may require you to take two, or more likely three, ruffs to establish perhaps one trick.
Look at these two suits – neither has any losers, but in spades you will only make the ace and will then have to take two, or probably three, ruffs in order to establish one more trick. In hearts, the king is perfect support and there are likely to be five running tricks.
When you have shortage in your partner's suit, downgrade your hand.
In contrast to this is shortage in the opponents' suit. With shortage in the opponents' suit upgrade your hand. The reason for this is that your singleton is more likely to be opposite weakness in your partner's hand and you will therefore be able to ruff his losers.
