אנו שמחים לפרסם את הכתבה החמישית והאחרונה- בנושא "הערכת היד – יד טובה-יד גרועה" (המקור: mrbridge).
והפעם, עשיית שימוש בשיטת ההערכה "טוב / גרוע".
זה הכל טוב ויפה לסכם את הנקודות בידך, אבל מה אתה עושה כשאתה באמצע טווח? כאשר המכרז מתחיל 1NT – 2NT, מה אתה צריך לעשות עם 13 נקודות? כאשר אתם מגיב על 1NT, מה אתה צריך לעשות עם 12 נקודות?
דוגמאות נוספות של שימוש בהערכה "טוב / גרוע" הינו כאשר (LTC (Losing Trick Count נותן לך ערך של חצי: איך אתה יודע אם ההכרזה שמרנית או אופטימית?
התשובה לכל השאלות הללו היא פשוטה: אם יש לך יד 'טובה' לך על הכרזה באומץ, ואילו עם יד "גרועה" אתה צריך להישאר נמוך.

HAND EVALUATION 44
Good Hand, Bad Hand
Part 5 of 5
by Bernard Magee
MAKING USE OF THE 'GOOD/BAD' EVALUATION
It is all well and good totting up your points, but what do you do when you are in the middle of the range? When the auction starts 1NT – 2NT, what should you do with 13 points? When you are responding to 1NT, what should you do with 12 points?
Other examples of using the 'good/bad' evaluation are when the LTC gives you a value of a half: how do you know whether to bid conservatively or optimistically?
The answer to all of these questions is simple: if you have a 'good' hand you bid boldly, while with a 'bad' hand you should stay low.
Here is an example:
You open 1NT on both of these hands and hear your partner respond 2NT. What next?
Hand E is very poor and with a 3-4-3-3 shape, isolated honours and no intermediates, the hand is worth closer to 11 points than 13: you should certainly pass.
Hand F is the complete opposite: good shape, with two robust suits; honours working together and tens and a nine to help. This hand will be better than many 14-HCP hands and is worth the raise to game.
Responding to 1NT with 12 points
When responding to 1NT, you should try to get into the habit of never having 12 points! This sounds silly, but what I mean is that, if you have 12 points, then try to decide whether it is closer to 13 (a 'good' 12) or 11 (a 'bad' 12). You will get much better results by doing this, rather than by using a convention to show either 12 or 11 points in different ways. For example, you may find that two 'good' 12-point hands may well make 3NT, whilst two 'bad' 13-point hands may not.
Learning to evaluate the strength of your hand, rather than relying solely on raw point count, will allow you to bid more good games and avoid bad ones.
What should you respond to a 1NT opening (12-14) with these two hands?
Hand G has a little shape and the king-queen of diamonds working together, but, with three isolated honours and no intermediates, it is at best a medium hand and should simply invite by bidding 2NT; remember that if partner has a 'good' 13, he will go for game.
Conversely, Hand H is an excellent 12-count: two tens, all the honours working together, and a five-card suit. The five-card suit is not worth a point on its own because it is not particularly robust, but if you take it into account together with the hand's other attributes, there is no doubt that you should raise to 3NT.
'Good/bad' evaluation is very important also in connection with the LTC:
Your partner opens 1 and you respond 1 (there is no opposition bidding). Now he bids 3. What do you call?
Count your losers: your first count should reveal 9½ losers, which suggests passing (your minimum should be 9).
However, the first thing to note is that your isolated queen is actually in your partner's suit and should therefore count as a full winner, making the total nine losers; and a fifth trump is worth another half winner, taking you to 8½ losers – in between a pass and 4. Which should you choose?
The LTC does not evaluate jacks or tens specifically, but, as mentioned in Chapter 5, a jack-ten combination can be very powerful, especially in conjunction with an ace or a king. In spades the combination is worth taking off half a loser, and in diamonds it is a positive factor. You should always be wary of upgrading a hand too far, but, with good support for partner's first-bid suit and two jack-tens, you should regard your hand as 'good' and go for game.
Your partner held Hand J:
Just 21 points between you, but, with the double fit, there are ten easy tricks. Two hearts and one diamond are the opponents' lot.
