אנו שמחים לפרסם את הכתבה השישית מתוך שבע- בנושא " הערכת היד -בסלאמים " (המקור: mrbridge).
בכל שלב של המכרז, קפיצה לגובה 4 בסדרה החדשה ניתן לשחק כהכרזת splinter. ברגע שאתה תתרגל להשתמש ב-splinters, זאת הבנה סבירה שתהיה לך ותעזור לך למצוא כמה סלאמים מצויינים.
הכרזות Splinter מתאימות בדיוק עם cue-bidding , אבל למרות שלאחרונה התייחס אליהן מחבר הכתבות, זה נושא קשה מאוד, משהו שדורש כמה כתבות נוספות לטפל בו כראוי.

HAND EVALUATION 51
Hand Evaluation in Slams
Part 6 of 7
by Bernard Magee
Other Splinter Bid Situations
At any stage of an auction, a jump to the four level in a new suit can be played as a splinter bid; once you get used to using splinters, this is a reasonable understanding to have and will help you find some excellent slams.
Splinter bidding fits neatly with cue-bidding, but, although the latter is a subject that we have touched on in this book, it is a very difficult topic and something that requires a few chapters of a book to be dealt with properly.
Here is another example of a splinter bid:
Why is East jumping to 4 when 3 (Fourth Suit Forcing) would have been a strong bid? The answer is that 4 cannot be natural, so it is used as a splinter bid.
East makes a good initial response of 2 - with a strong hand you should bid your shape naturally, starting with the longest suit. When East hears the 2 rebid, he is very interested: 6 losers suggests bidding to 5, so a 4 bid really would not get the strength of your hand across in these circumstances. What is required is a descriptive bid that might tempt partner to go for slam and a splinter is the perfect option. The jump to 4 shows shortage and agrees the last bid suit (hearts), promising primary support (at least four cards). It also shows the values for at least a game contract.
West has a perfect fit: an isolated ace means there are no losers in diamonds and no wasted values. With 5 losers and the perfect fit, West uses KCB and settles for 6.
The final example illustrates how you might show a void, by using a splinter bid and then bidding the suit again afterwards:
West opens 1 and East makes a splinter bid, 3, showing shortage in spades and a raise to 4 (remember that since pre-empting partner makes little sense, the 3 bid here is not used in its natural sense). West is quite happy with his holding in spades, but is rather weak; he shows willing by cue-bidding an ace: 4 . East rebids spades (4) to show a void in the suit and now West can get really excited. He has no wasted strength in spades at all and thus his partnership is playing with a 'thirty point pack' – points in spades are irrelevant.
West has 14 HCP outside of spades and his partner should have a minimum of about 12, which leaves just 4 points out of the 30 outstanding – that translates to just one loser. West uses KCB and finds that East holds no ace, so 6 is the limit.
