Are BBO hands in clubs random or specially selected according to certain criteria. They certainly don't seem to fit the pattern of randomly dealt hands

What do you think the "pattern of randomly dealt hands" should be? By definition, random hands should have no pattern. People tend to have misconceptions about random sequences.

Lucky you! Only the biggest clubs here can afford a dealing machine, so hand preparation is mainly manual even when the deal itself is by computer. Typically clubs play one or more national simultaneous tourmanents every week and the hands are either prepared by the Director or (for less important tournaments) by the players themselves in a non-playing first round. Other local tournaments and Teams are shuffled and dealt by hand.
There is an interesting alternative to traditional dealing machines which might catch on easily here if it becomes mature.
Of course with tablet based play looming, the whole issue may become academic.

The original poster felt that your RNG was biased.
You response is talking about predictability.
Hard to understand how it could be difficult integrate BigDeal.
1. Seed a high quality PRNG
2. Start reading off big numbers
3. Convert big numbers into hands
4. Store hands in a buffer
Reseed every now and then

Yeah, I was just thinking about all the potential problems that a poor dealing algorithm could have if it's not really random.

There were some Linux compatibility issues we ran into. It also requires operator input to generate the initial entropy, we'd want to automate it using something like /dev/random. And we have to ensure that it can keep up with our need for new hands.
We had some email discussions about it a couple of years ago, but it's never seemed important enough to actually replace what we already have.
