i also think tools about counting would be very useful. At some point in the play you ask players what their initial hand was, which card the opening lead was, what they think the 4 hands may be, and so on. At the end of play you ask to write down the full deal then compare and let them discover what did escape them. Another trick worth experimenting: you show a player his hand and dummy's then make him play blindly. At some point you simply ask him how many tricks are left to be played.

i am playing in a 2-week friendly tournament in France. 16 matchs every evening playing the same deals (no kibbitz allowed), starting at the same time except for one which is broadcasted on youtube with a 30 mn delay. i thought the broadcast was delivered with the delay but it's live and it's the start of the match which is delayed. Maybe it would be an improvement next time if the technical problem can be overcome.

Overcall 1S and when doubled in that contract, hope an imperfect defense will let it make.

Smolen is an available tool. When you think it will be useful, you use it. When you think another way will be more efficient, you do otherwise.

This a recurrent theme for problem makers. See problem number 20, page 43, at https://roquibridge.files.wordpress.com/2014/04/tour-de-table-en-80-jours-tome2.pdf

These regulations adress some issues that can't be checked: distance and communication between teammates and is silent about some others: consultation of system notes, use of writing. Is it puposeful?

Online, would not it be preferable if the software waited until your RHO had played, to simulteanously show you the 3 played cards? And the same in the biding?

Quite often, especially when playing with screens, a defenser may want to get information and not to let declarer know what he is interested in. The goal is the same than the purpose of CC, but the information is not always available in the CC… and there is not always a filled CC!

I can't understand how players can be negligent enough to leave the table. They are needed to take cards played from dummy and to answer opponents'questions.

Partly because the question was not clearly formulated, partly due to errors.
You may control the calculation and signal errors in this excel file:

“What is necessary is for OPer to give a more precise statement of exactly what he is asking.”
I agree with Craig's statement that the question was not clear. I also agree with his simulation if he only looked at one precise hand on every deal, which was not clear in his description. Otherwise it's futile to run simulations when it's easy to make an exact calculation. If you don't want to count the number of hands fulfilling a criteria, you can use a shortcut by using the known probabilities of global repartitions of hands and adding the parts of them which fulfill the criteria.

When counting deals you introduce a bias. It will not be uncommon when a hand has 6 spades that another hand of the same deal has 6 hearts. it will be more unfrequent that when a hand is a major 2-suiter that another hand of the same deal is also a major 2-suiter. It may even happen that a deal is formed of 4 hands with 6 hearts or 6 spades but it's not possible that a deal contains more than 2 major 2-suiter hands.

for 6+ H/S it's 1/2 of hands with a 6+suit except for 6610 and 7600 where it's 5/6
for 5+4+ HorS it's 1/6 of hands with at least 5/4 in 2 suits, except for 5440 where it's 1/3
roughly, it amounts to 10.31% for 6 and 6.40% for 5-4 (with partial overlapping)

A possible solution is to use transfer responses over 1C. So you integrate one range with 1C/D 1X 1NT (for instance 13-15) and another one with 1C 1X 1Y where Y is the transfer rectification (for instance 16-17). The downfall is that you have to open all balanced hands in the 2nd range (16-17) with 1C.

You are rignt, I was confused. Maybe Cavendish only takes place on odd years.
