True. (I took Steve M's comment to be contrasting rule-based decision making with AI.)

Jim, what do you see as indicating lack of understanding?

The team coached by Kehela represented North America.

I was under the impression that treating people with respect predated political correctness by several millennia.

It took me a while to see that to get from the table in Solution 1 to the conclusion that finessing against East was roughly equivalent to playing for the drop, the number of layouts having a West singleton club should be multiplied by 3/4 (to exclude stiff Q, which either plan handles), and the number of 2-2 layouts should be multiplied by 1/2 (to exclude Qx with East, which again either plan handles).

Page 3, third paragraph, “tump coup” -> “trump coup”.

Does that mean it must have been Belgium?

I don't see how East could expect to gain by not taking the A and returning a heart.

“The 6 suggests five cards are outstanding higher - we can see three and West has one more.”

That would depend on the rank of the heart that was omitted from the diagram.

A team's telling the opponents that it might be withdrawing after a future set taints the results and doesn't serve a purpose that I can see. I think it's fine if a team wants to inform an official about a possible future withdrawal so that the tournament staff can make contingency plans.

It would be useful to know the spot cards added to the declaring side's hands or played by the defenders. But, I'm placing the A with West, who I'm guessing refrained from rising and playing hearts from the top in case Declarer started with Q98x. For West not to be afraid that the Q is Declarer's ninth winner, West probably anticipates getting in with the Q. So, I cross to a high spade and lead the J for a finesse.

Added: I'm not saying that I agree with West's duck at Trick 2.

What were the ranks of the 13th cards for North and South? And what spots did the defenders play at Trick 2?

Doubling seems a likely winner here. Both defenders can infer that the declaring side doesn't have longer spades than clubs. This suggests that leading a spade when Partner actually holds the K is less likely to lead to a squeeze than is leading a club when Partner actually holds the K.

From the vugraph commentary:

Vugraphzfb: Zia [South]: “Just bid 4, I didn't know what you were doing” Cheek [North]: “I didn't know what you were doing - you might have had AK of diamonds”
kit: On actual auction, South was worried about being off the first 2 club tricks.
Vugraphzfb: Cheek: “I”m sorry, I didn't know what was going on - at no time did I know I was getting raised"
fabsayc: if cheek had no club control, would have rebid 4
Vugraphzfb: Zia: “we should actually play 4 by me would be forcing after a positive response”

I especially liked the following insight from page 9:

“The problem is that the grand may depend upon the play as well as the bidding . . . If I misguess and they guess correctly at the other table, that would be even a bigger adverse swing.”

Hi Adam,
I couldn't agree more on the value of imparting concepts to students. But I've found that it requires considerable judgement and mental agility of the instructor. I therefore suspect that a concept-based bridge curriculum wouldn't scale nearly as well as one based on rote, the latter's shortcomings notwithstanding.

There's also the matter of how to address the ACBL's having certified numerous teachers using the rote-based curriculum. Would there be a new, concept-based certification? Would that replace or be a step beyond rote-based certification?

Finally, this all assumes the ability to overcome decades of institutional inertia in this area.

The only line item I see that seems germane is “6001 Forum monthly cost 40,200 $40,200”. (The first amount is under the “BOD” column; the second is under the “TOTAL” column.)

Added: The word “monthly” appears to modify “Forum,” not “cost.”

You might consider also posting an article in the ACBL Elections Forum.

I thought Bernard's point was that if East was 5=3=3=2, hen* could have ruffed in early enough for the defenders to cash a diamond.

Therefore, it seems that after regaining the lead at Trick 5, Declarer needs to play East for at least three clubs or at most two diamonds.

I recall Alan Miller as the author of “The Cynical Observer.” Apparently, the column's authorship changed or rotated.
