Also, would you pass with a pure penalty X? If your X was only way to show a good hand, trying to catch lots of tricks opposite your controls gains in popularity

Obviously software makes possible solving problems that couldn't be touched otherwise. The problem is that before one may formulate any interesting problems to solve, one must learn quite a lot the hard way. Learning arithmetics in grades 1-4 combined with elements of algebra is a perfect start.

I should have made an exception for elite universities. During my PhD I spent some time as a visiting scholar at Booth and discovered that even MBA students were really good at such things like econometrics while at my turf linear regression was a hard limit

I don't know what do you mean by math. Being fluent in the equation of straight line and solving two linear equations with two unknowns will yield a bachelor's degree with at least decent GPA in every business school in the North America. Not having ability to attain this level of ‘math’ probably dooms you as a bridge player. If one is able to say, derive new results in differential geometry the story gets complicated. My father who was at this level made me never take up chess seriously since he always played in earnest. On the other hand, he was my frequent victim in card games but his enjoyment of cards was limited at best. I knew several good to very good mathematicians in academic sense who played bridge and my sense of this group is they generally lack killer instinct. Of course, there are exceptions like Szurig who both developed Polish club and was an expert player.

Don't worry. It's a practice problem and in practice problems they don't jump to the three level with five trumps.

Canadian and Mexican club managers should have the same proportion of their revenue in Canadian $ or Mexican pesos as their income like Mcdonald's franchisees have instead of this proportion fluctuating with exchange rate.

Oops - I meant it for intermediate forum, but I hope it's sufficiently entertaining here

Donald, I don't get your attempt at rationality. All corporate entities inclusive of franchise systems like Mcdonald's are subject to currency risk, which they may hedge or not. It is ridiculous that a non-profit organization like ACBL passes all the currency risk to their non-US franchisees. Economically it is akin to Mcdonald's franchisees in Bangladesh being forced to purchase frozen fries and ground beef in the US.

Game forcing rebid not only does not promise 100% game but also does not promise that a game will have a play. 2 cover cards is not an obligation in 1 response

You can still edit your post and put a hand diagram. 4 and 4?

I like more stories how 1-P-P-? harvested 1400 for the opening side with some five point rubber originally at stake

Joel, reading your stories was well worth a visit. ACBL seems to be like a communist country where reaching the stated goals is perfectly impossible with use of the prescribed means while the ruling bureaucratic class is kept in good shape. In the communist countries which eventually had to go bankrupt, the previously ruling cast became the new riches. In the ACBL the ruling class can't count on that but they may be still supported for some time if there is enough crazy game enthusiasts willing to invest their blood, sweat and tears.

Since xx,xxx,Qx,AKxxx or some permutations of it make the grand almost laydown, perhaps an attempt to reach it makes sense

If it isn't, -930 will yield a great educational opportunity for our partner

This has really nothing to do with the problem in general, but against every 4 contract, the W. Bot led from Kx to score a ruff with its stiff trump and there was also an unavoidable loser
