Bridge Information

Favorite Bridge Memory
Beating the world champions in the New England Knockouts.
Bridge Accomplishments
Two open regionals back when winning a regional event meant something. More sectionals and flighted or bracketed regional events than I can remember.
Member of Bridge Club(s)
Tom Cheetham Club, Nashua, NH
Favorite Conventions
Light takeouts. A direct 1NT overcall is an 8-13 HCP takeout with two or three spades. A direct cue-bid over 1C, 1D, or 1H is an 8-13 HCP takeout with four or five spades. Double is 14+ HCP and can be offshape.

Another Question for Mathematicians--well...Statisticians
A friend, who is something of an expert in the field, says that there are non-quantum hardware RNGs. I asked him to post a description in here but he may be too busy.
Another Question for Mathematicians--well...Statisticians
The Enigma machine was indeed a PRNG. It used a very complex pseudo random character substitution mechanism. The only truly random element was the secret list of keys (seeds if you like) needed to use it by operators on both ends of the network. I've never read anything about ...

That sounds like "need for speed," which is a car racing game, so I can't tell whether or not you're serious. If you are: https://en.wikipedia.org/wiki/Pseudorandom_number_generator https://en.wikipedia.org/wiki/Hardware_random_number_generator
Another Question for Mathematicians--well...Statisticians
Does Nic's program imply that someone could play three hands, transmit them to someone running the program, and get the rest of the hands? I suppose with today's spy technology it could be done. Maybe I watch too much TV. Has there ever been a real-life instance of ...
Another Question for Mathematicians--well...Statisticians
"The original purpose is to avoid any possible suspicion about any kind of manipulation of the hands." No other purpose is mentioned so I'll address that one. Is manipulation of the hands really the most important concern? Given what's happened in the last few years, I would think ...
Another Question for Mathematicians--well...Statisticians
I'm not familiar with the audit capabilities you mention. If you would be so kind, please describe their purpose and how they work.
Another Question for Mathematicians--well...Statisticians
When "computer hands" were first used, people complained about too many bad splits. My theory is that those people shuffled a deck only two or three times before dealing it out, resulting in hands where almost every suit breaks evenly. You would rarely see a 4-0 or 5-0 split. No ...
Another Question for Mathematicians--well...Statisticians
When I was programming, a pseudo random number generator seed was simply a starting point in an extremely long sequence of numbers. In theory, using the same seed and generator repeatedly produces an identical set of results but the seed itself has no effect on the sequence. I've never ...
Another Question for Mathematicians--well...Statisticians
> Suppose, for instance, that the random number generator for that day always gave the partner of the hand that had the 7 on one hand the 4 precisely 17 hands later, but that was its only flaw. That's not possible. Even the worst pseudo raandom number generators produce finite ...
Another Question for Mathematicians--well...Statisticians
>> There are people who think today's software is still flawed. >> It's hard to prove otherwise. > When you say that people think that the software that the ACBL is > currently using is flawed, are you referring to random cranks or are > > there legitimate criticisms? It's what I hear ...
