Help
Hi
Reason for the question..
We have just played 12 hands with friends using ***Social Bridge*** ***Play Duplicate Tournament Deals***
(I have some BBO$ which I don't mind spending in order to get a comparison with 'experienced' players.)
We (N/S) had the 'balance of the points' on every hand. I think E/W played one hand but that was a sacrifice to stop us from making 'Game'.
Assuming that the hands are randomly assigned to N/S or E/W the situation seems analagous to spinning Heads 12 times in a row with a fair coin.
The probability of this happening is (0.5)^12 or 0.00024 (Roughly 4000 to one against)
Our friends / opps are naturally a little peeved by this and claim (with some justification I suggest) that the hands (that is to say 'the points') are not being assigned randomly..
Am I looking at a glitch here? Or what is happening?
Thanks.

Is BBO biased towards players who buy BBO$

Yes, but it's done by hand.
BBO has assigned one of its employees to count the points and divide that by the number of BBO $.
Interestingly, it only applies to paying customers sitting NS.
Otherwise they'd need to employ an EW counter, which would exceed their budget.
There's a plan to randomise the person between NS and EW, but they would need an extra person to roll the dice for this.

One in 4000. There are currently over 2000 tables in play as I write. Assume 12 boards takes 90 minutes, that means this happens 6 times a day.
And if it was only 11/12 (either the sacrifice wasn't really, or they didn't compete enough, or...), that ups the frequency to 3 times an *hour*.
On another front, one of the joys of duplicate (not unalloyed, defence really is harder than declarer play) is that you can get great scores if you defend well, even if you don't get the cards.

I remember a night where I had less than average points on almost every hand
But I do hope they bias things towards those of us who pay for more BB dollars
I love the size of the Bridge universe. Just think there could be some poor person who never has a good hand their whole life
