אנו שמחים לפרסם את הכתבה השלישית (מתוך 6) בנושא " הערכת היד – ספירת לקיחות מפסידות – צעד נוסף קדימה" - "The Losing Trick Count A Step Further " (המקור: mrbridge).
הכותב הראה שה-LTC בפעולה במצב בסיסי כאשר הפותח והמשיב מתחרים באין מפריע מתחילים בגובה אחד, אבל ניתן להשתמש בו בכל מצב, כאשר נמצאת התאמה. אתה לא צריך להיות כל כך ספציפי במצבים אחרים, אבל, על ידי ספירת המפסידים שלך, אתה צריך להגיע להערכה טובה לשווי ידך .
הכתבה היא בשפת המקור=אנגלית. בהמשך אעלה את התרגום בעברית וכתבות נוספות.

LOSING TRICK COUNT in DIFFERENT SITUATIONS
I have shown the LTC working in the basic situation when opener and responder are bidding undisturbed starting at the one level, but it can be used in any situation when a fit is found. You do not have to be so specific in these other situations, but, by counting your losers, you should reach a good assessment of your hand's worth.
These values are approximate, but by comparing to the values you need to know (7 for an opening hand and 9 for a responding hand) you can assess the values for other bids by estimating about 1 loser for every 3 points' difference. A minimum overcall would be made on perhaps 8 or 9 points, which is a high card less than an opening bid, hence the approximation of 8 losers. A Strong Two opening will usually have 20-21 points – that's three high cards (3 x 3 points) more than an opening bid, which would place it with about 4 losers (3 losers fewer).
It is important to note that the values given in the table above are to help the bidder's partner make an assessment when he has a fit; they are not meant to be a guide on when to bid or not to bid with a particular hand. Some responding hands will have as many as 10 losers and some minimum overcalls will have 9 losers; stick to your normal methods for bidding these hand types.
Using the LTC precisely in competitive auctions is not easy and usually the length of your fit and all-round strength takes precedence, but understanding the values above can help you assess your partner's hand and counting your own losers can help you assess your own.
You have a fit for spades, so count your losers: 8. Now do a quick calculation: his minimum should be about 4 losers, so 4 + 8 = 12. < Subtracting 12 from 18 gives 6 – you should be thinking about 6!
Not many players would have been thinking of slam with such a hand, but the LTC helps you evaluate hands accurately. Of course, you would not leap to slam, but you would express interest in a slam, bidding 3 (in this sequence a stronger bid than 4) or by making a 'Splinter Bid'.
Your partner's hand is:
6 is very likely to make, with thirteen tricks possible if the club finesse works. You have only 27 points between you, but the singletons are worth so much in contracts like these. The LTC can help the weaker hand to participate in auctions like this and allow it to believe in the chance of slam as much as the strong hand.
