With good pupils, show that playing
a low card on the lead assures them of two tricks in the suit. |
| 23.2 |
You can mention the fact that there
is interest in ducking … without showing declarer that you have a
problem! The latter will no doubt repeat the finesse in Clubs and
will only make one trick in the suit. |
| 23.3 |
In principle, these rules are automatic.
So it is not a question of teaching them to judge competitive
situations. |
| 23.4 |
The reasoning is presented by taking
the opponents' game call as the basis. It is obviously also
applicable at the slam level, but more rarely; moreover the calculations
are more complex. |
| 23.5 |
A more precise formulation of the
rule consists of not allowing to double except if the "attacking"
side has a greater number of H points. |
| 23.6 |
Here again, there is no question of
allowing the pupils, for the moment, to evaluate their defensive
potential and giving them the freedom to defend or not according to
the impression they have of their opponents' contract being successful.
|
| 23.7 |
This communication of little papers
may be forbidden in the preceding lessons when the side which bids
first declares a game call. |
| 23.8 |
To very good pupils you can leave
a very slight margin for manoeuvre in the case where the presumed
failure is very costly in comparison with the contract reached. You
can explain to them, for example, that if the opponents bid a contract
worth 620 points and that over-bidding will cost on average 300 points,
they must only do it if they feel that the opponents' game has three
out of four chances of winning. |
| 23.9 |
In which case the defender does the
same profitability calculations. If he decides to over-bid, the turn
comes back to the other side who can over-bid again or double. And
so on!! |
| 23.10 |
You can leave to enterprising pupils
the benefit of a "small risk" (- 1 point according to the Decision
Table), if they possess at least nine Trumps. |
| 23.11 |
You can get your pupils to notice
that, in reality, the attacking side only has the possibility of over-bidding
if he has bid a major suit game. In minor, in fact, the level
of an over-bid is a slam which would have been bid directly. |
| 23.12 |
… even if a complete analysis shows
that South could get away with one under-trick by replaying Clubs
immediately, and by establishing the fifth Club to discard a losing
Heart. |
| 23.13 |
The simplest is still to lead the
singleton in Hearts, better than the head of sequence in Diamonds.
West must play a low card from dummy and take South's 10 with the
Ace. He will then only give one Club, one Heart and one Spade trick.
