אנו שמחים לפרסם את הכתבה השנייה מתוך שבע- בנושא " הערכת היד -בסלאמים " (המקור: mrbridge).

המכניקה של הכרזות סלאם אינה במה שאנחנו מתמקדים כאן, מה שיותר חשוב בשלב זה הוא האופן שבו התפתחות המכרז יכולה להשפיע על הערכת היד שלך.

נתחיל עם כמה מכרזים ארוכים ונראה איך הם יכולים להוביל אותנו לסלאם (ידי מערב זהות בשתי החלוקות):

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

HAND EVALUATION 47

Hand Evaluation in Slams
Part 2 of 7
by Bernard Magee

 We begin with some long auctions and see how they can lead us to slam (the West hands are identical in the two layouts):

Both auctions start in the same way, with West opening 1 and both Easts responding 1NT because they do not have quite enough strength to bid 2. Now the West hand rebids 2 showing its strength – a reverse bid promising 17 or more high-card points. Both Easts now show their long diamond suit, about which West is quite excited! Counting his losers, he finds he has just 5, including three aces. He also has a good five-card suit, so he raises to 4 with one eye on a slam. This is where the auctions begin to differ.

The most important element of both auctions is to picture West's hand: he has shown five hearts and four spades and is now supporting diamonds. That does not leave much room for clubs; in fact, he is very unlikely to hold more than one club. Bearing this in mind, the two Easts can judge what they think of their hand.

In Layout 1, East is very happy indeed: nothing wasted opposite partner's club shortage and each of his isolated honours are in partner's suits; with just 7 losers in his hand (the lack of aces is balanced by the six-card trump holding) he should harbour hopes of a slam. Rather than simply raising to 5, he shows a control on the way by bidding 4. It is not so much what the 4 bid shows that matters; the important fact is that it is a slam try. West will be happy to accept the try because he was hoping for slam himself. He bids Key-card Blackwood and finds that partner does have one key-card (the K) which is enough for West to bid 6.

In Layout 2, East is less enamoured of his hand: his queen of hearts is all right since it is in his partner's suit, but his queen of clubs is distinctly weak and, opposite a singleton, will carry no weight at all. He should evaluate his hand at 8 losers and should be happy to settle for 5. With no hint of a slam try, West would pass too.

The mechanics of slam bidding are not what we are focusing on here; what is more important at this stage is the way in which the development of the auction can affect your evaluation of your hand. East in Layout 1 starts with a relatively poor collection of cards, but with every bid from partner his hand grows and grows in stature. 1 enhances his queen of hearts, 2 enhances his king of spades and, when partner supports his diamonds, the transformation is complete.
