Leonard Helfgott's bidding problem: A92 Q A42 KQT763
Richard: 5-6 hands are narrow targets indeed. And if partner did have 5S you would hear it over ANY rebid. I like 3S, but for other reasons.

Pons Asinorum translates to "Bridge of Asses" which refers directly to Euclid's elementary geometry proof that the angles opposite equal sides of an isosceles triangle are equal. (Presumably only an ass (donkey) would be unable to cross the intellectual bridge to find this easy proof). I wonder how the ...
Another Question for Mathematicians--well...Statisticians

Frankly, I don’t recall when to divide by sqrt(N) or sqrt(N-1), but for these purposes it seemed OK. Thanks ...

Do you add 1Hcp for all 4 Aces?
Craig: Thanks for the number crunching, always informative. Choosing to open 2NT or not does not “destine” the hand for 3NT play. As you mentioned, partner could easily be balanced and hold 5 spades or 4 hearts and be able to get to 4M, or in the latter case raise ...
Do you add 1Hcp for all 4 Aces?
Nigel: I am in general agreement with you, especially where a 2NT opener can more easily propel into a making major suit contract, as opposed to being passed in a 2NT rebid.Regarding evaluation, I have performed a “meta-analysis” of Thomas Andrews “Fantasia” stupendous 2NT analysis (which I can make ...
