Does BBO monitor its systems to insure that they are operating within normal tolerances? Yesterday, in the space of 13 hands in ACBL robot individuals, I encountered 3 5-0 breaks and a 4-0 break. Today, the first 2 hands I played featured a 5-0 break and a 3-0 break. The next set included a 5-0 break.

I am not suggesting anything nefarious - who would benefit from tinkering? I am concerned, however, that low-percentage breaks may be occurring more often in BBO than in real bridge or that they are less randomly distributed in BBO than in real bridge. Either should be cause for concern.

We recently had the author of BigDeal, who is generally considered one of the best experts on dealing bridge hands, perform a statistical analysis of our hands. He determined that our distributions are as they should be.

There is even a test case in the dealer package that shows how close statistically hands are to real random hands.

Only problem is that humans don't understand random. True randomness generates sequence of events quite often that human matches as non-existing patterns.

Good reading about this is spotify random play list article at bbc. http://www.bbc.com/n...nology-31302312
