"הערכת היד – ספירת לקיחות מפסידות בפעולה" – כתבה שנייה (אנגלית) מאת גבי לוי

פורסם בתאריך 26/10/2011.

אנו שמחים לפרסם את הכתבה השנייה (מתוך 4) בנושא "יישום שיטת השוואה - הערכת היד – ספירת לקיחות מפסידות – בפעולה"  -  "The Losing Trick Count in Action " (המקור: mrbridge).

כזכור עסקה הכתבה הראשונה בנושא  ספירת לקיחות מפסידות בידו של השותף, דהיינו לאחר ספירת הלקיחות המפסידות בידך, יש להוסיף את מספר הלקיחות המפסידות בידו של שותפך, ולהחסיר הסיכום מהמספר 18. התוצאה הינה גובה החוזה שיש להכריז.

במקום לעשות את כל העבודה הזאת, אתה יכול פשוט להשוות את היד שלך למינימום LTC שלה.

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

HAND EVALUATION 16

The Losing Trick Count in Action
Part 2 of 4
by Bernard Magee

APPLYING THE COMPARISON METHOD

Rather than doing all this work, you can simply compare your hand to its LTC minimum.

So on the East-West diagram in Layout 1, the auction would still start 1-1  . After East's 1  response, West knows that they have a spade fit and can count his losers: 6. Now all West has to do is compare his hand to its minimum: 'As opener my minimum hand is 7 losers; with that I would respond 2, but I am one better, so I bid one more: 3.'

Then the responder (East) does the same, but of course he compares his hand to his own minimum (9 losers for a responding hand). With 9 losers he would of course pass 3, but with 8 losers (one better) he bids one more: 4.

Isn't that a lot easier? No long calculations, just compare your hand to its minimum; all you have to remember is whether you are the opener (minimum: 7 losers) or the responder (minimum: 9 losers) – and that is not so difficult, is it?

You can actually put it in table form:

As responder, it is very important to differentiate between 'strong' (point-wise) and 'distributionally strong' hands with 7 losers. To see why, have a look at these two hands, both replying to a 1  opening bid:

Both have 7 losers, but should they really be bid in the same way?

Hand A responds with 4, the direct raise showing a distributional hand. Whenever you have a weak hand with support, raise the suit straightaway to the level suggested by the LTC.

Hand B starts by bidding 2, planning what is called a 'Delayed Game Raise': taking advantage of the fact that partner has to make another bid, you plan to jump to game after he has made his second bid, therefore delaying your raise to game by one round. This is not wholly satisfactory, but at least it tries to convey your high-card strength as opposed to your distribution, which can be very important when it comes to slam bidding. There are some conventions that allow you to deal with these types of hands, such as the Jacoby 2NT response or Splinter responses, but they require agreement and more study. To make a delayed game raise, you should know of an eight-card fit with partner and your second suit should have at least four-cards and ideally it should have two of the top four honours in it.
