about me

The most information about me is at my website, http://www.jeff-goldsmith.org/  (The ".org" is misleading.  I'm not very organized.)  The bridge stuff is pretty extensive; it's been going on for 20 years or so.

In real life, I'm a software engineer.  I used to be a computer animator.  I did a lot of stuff which sometimes plays on Nova, including Voyager's encounter with Neptune.  A curious happenstance: I was sitting at a table at a nationals and realized that three of the four players were trained as differential geometers.  Not a common occupation.  Nowadays, I work at making the internet faster.

In bridge, I'm a team lead on the National Appeals Committee and a casebook commenter.  I've done more than thirty of them.  I'm a minor member of the Conventions and Competition Committee (C&CC), minor because my appointment came at a point in life where I am unable to attend many nationals.  I made this clear before accepting the nomination.  With some luck, that will change; I hope to get to two of them a year for the next few years.  As a working stiff, I tend to play on weekends.  Most of my vacations are national bridge tournaments.  Some of my previous partners have been some of bridge's more colorful figures.

I'm also into strategy board and card games.  I can often be seen at nationals after the game playing/teaching/toting them.

ACBL and psyching 1N. Again?
I think this is clearly a psych. The hand is nowhere near the strength of a strong NT with all the cards in the short suits. Regardless of whether it fits the letter of the regulations defining a psych, it's completely obvious that it was meant as one by ...
XYZ Problem Hand
These days, there's some confusion between "XYZ" and "two-way checkback." The latter applies only after 1NT rebids; the former is more general. As far as I know, the first publication of two-way checkback is by Kit Woolsey in the Nov/Dec 1990 issue of Bridge Today. He claims it ...
Move the Date of the Fall NABC!
It is to me. I'm a working stiff. If fall nationals are over Thanksgiving, I get to play two more days than I would if it were not. On the other hand, someone is always getting most of the players sick...I've been considering ditching the fall nationals ...
Jacoby transfer followed by minor followups
Fewer than three spades. Either worry about clubs for 3NT or a good fit for diamonds and interest in bigger things.
A Mentoring Program with a Twist
I used to do something similar, but I used a sort of Rainbow movement; each table always had one pro and three students. The students played three boards at each table, so that each played one board with the pro. As a result, one pro always came in first North ...
Rating Study from ACBL Tournaments
That effect (survivor bias) should show up in different guises, but I don't see why it should do so here. Hmmm...to test this theory, rerun the data by eliminating boards played against non-qualifying opponents and see if this persists. The knobs on ELO rating systems are very complicated ...
Theoretical Laws questions about playing out the hand after a claim
Right, which of course it does. It would have been better that the laws commission had added "...to cards exposed during the claim," or the like, but that's pretty tricky to get right, as the claim has been voided, so the sentence would then be meaningless in some sense ...
Theoretical Laws questions about playing out the hand after a claim
I wrote, "don't bother to ask," because I won't say, it's too long to be interesting anyway, and if you heard it, it wouldn't change whether or not you believe me, so don't bother to waste your time. "Say" can include both express and implied ...
Rating Study from ACBL Tournaments
I'm curious. Is it intentional that the mean of the (actual score - predicted score) should be +1%? (See Page 5.)
Theoretical Laws questions about playing out the hand after a claim
Actually, they do say that penalty cards stay. "The claim ... is void" means that it didn't happen. When nothing happens, penalty cards stay on the table. You are right in that players who have exposed their cards (necessarily the claimer, but perhaps not the opponents) may choose to play ...
