“Resident polymath”—you’ve let the cat out of the bag there, James. All these years I’ve been thinking that David Burn was just a regular guy like the rest of us.
For Those Interested in AI and Bridge
There is a footnote in the paper that might be significant. It says “One technical detail is that c is generated by assuming that the player who can win more tricks in the contract is the declarer”. So, if I understand it correctly, the evaluation does not consider right‑siding ...
Clash by Night
The 12-hour events are usually scheduled to run from about 11am to 11pm. I agree it's practically impossible to fit same-day international travel around this. It's easier to fit travel around the 24-hour event. (A slightly later start and finish would be better from this perspective.)
Clash by Night
The event ended at eleven. The organisers did not use the clocks going back as an excuse to torture the participants by making them play an extra hour.
Clash by Night
There's a case, but there's an admittedly unlikely layout where it would be seriously wrong. Declarer might have KQ doubleton in hearts (as well as a doubleton spade) and dummy three to the ten.
Clash by Night
I admit I much prefer the 24-hour event.
1m-1M (Minimum expected values) (1 of 2)
That seems a very reasonable approach to me. If I were to agree a minimum point‑count for a response, I might pick up some hand, which I hadn’t considered in advance, on which, at the time, I judge my best action is to bid. Then I would have ...
Forcing or Not?
While I agree that it is logical for “forcing” and “forcing one round” to have distinct meanings, and that “forcing one round” should sensibly guarantee a rebid, I don’t think that is how most understand it. If I agree with a partner that some call is “forcing one round ...
Splitting honors: which honor to play?
Seems to me that with QJx in particular, when the lead is from dummy to declarer, you should [b]not[/b] play the Q. Reason is you might play the Q from either Q10x or AQx. If you have Q10x, you definitely do not want partner to take the ace ...
Pass-1!D; 2!C
Yes, I play a passed hand 2 over 1 to show a 6‑card suit and a fairly wide point range. (More contentiously, I also do this over a third‑ or fourth‑seat 1 or 1 opening. It's more attractive when playing 4‑card majors.)
