They are not forcing but xxxx xx xx KQTxx is too weak a hand for that. Normal range is good 7 up to 11pc.

I don't really know why they have 12-15 on the cc for 1C etc. It's incorrect. I made the analysis for the Polish forum before but I can repeat it here if there is need. The analysis is based on what actually happened at the table (on vugraph ...

>>If the PBU keeps the title, they speak for all of Poland. If the Polish players don't replace the PBU with people that will do the right thing, then all of Polish players will have supported the actions of the PBU. Oh, so then every American is responsible for ...

Very small nitpick but it's important to get ranges right (and in this case even more incriminating in some cases). 1C = 12-14BAL, 15+nat or 18+any (not 12-15 and not 19+) This is important because there was a discussion about 1C - 1S - 2C - 3C hand which is different ...

>>No! That is never the right approach. You must use your data to develop a simple, working, test hypothesis, and check that against new data. Kit is trying to do just that. I consider it incorrect although I grant you that is not clear and there is a debate about ...

I am probably more conservative by nature, I think 1000 is a reasonable number. That doesn't matter at all anyway if there aren't any false positives it's just too much anyway.

>>In the beginning no one thought Boye had F-S and that he was being a drama queen. Of course, that was not the case. Then his team got F-N. This was so successful that he got the Germans to confess, which saved hundreds of man hours for Boye, Ish, Brad ...

>>The number of possible hypotheses may be infinite. Yes and here comes the judgement call. I think the most accurate way is to think about a set of "reasonable hypotheses" or the ones we would believe to be plausible, for example no one would take "look, five fingers mean either ...
