While I do not profess to be a mathematician or statistician, I have been playing a very long time. The frequencies of particular shapes seem to be happening more frequently than I personally would expect.

Let me be clear here, this is entirely anecdotal and I am hoping that somebody with the knowledge and skill to evaluate the hand patterns could verify that everything is normal.

I have the knowledge and skill to analyze this.

I am not about to do so because this has been beaten to death many many many times in the past.

If / when BBO

A. Announces that they have made some changes to their hand generation code
B Chooses to change the PRNG that they are using

then it might be an interesting project to consider

Absolutely. In fact, whenever I marvel at how often there are 8+ card suits on BBO, it turns out that almost 100% of the time there was an 8+ card suit on the current or previous hand. What are the odds of that??? You can't get more frequent than that

8.7%

The frequency seems to be increasing. In one 16 board set I played from 8:45 to 10:30 PM central time, I personally held both 8 and 9 spade hands. It has been a bizarre run lately, especially over the last 3 months. Granted I play a very large number of boards, but in my 52 years of competition, nothing like this. Granted this happens more often in the casual room. Thanks for commenting.

And I had both 8 and 9 card !s suits again tonight. Bizarre.

To be fair, I cannot remember if it was an 8 immediately after 9 tonight, but they were awfully close together.

Thanks for replying.

I've done numerous analyses of the distributions on BBO and always get exactly the same results; they're completely normal.

This is the Offline bridge forum. Where have you been playing offline that you see lots of 8-card suits?
