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

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.

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?
