It seems that if SK wins there is no LHO's distribution (which fulfills take-out double requierments) and their play that set the contract. Since LHO do not have SA (he can not duck the king), he must have CA. Am I right?

Without right guess in Clubs?

It could be interesting to know why did you reject 1S and 3C bids?
Or why will you choose those bids if someone will choose them?

How about 18 HCP flat. Six in minor is possible?
What do you suggest for 18-21 HCP balanced (if this is relevant for your scheme ?)

Do you assume 15-17 HCP always?
Is 5-4-2-2 distribution possible?
Is 5 in a major possible?

I just corrected the problem and formulated it more strictly. It does not mean, however, that the problem is easier. For some readers it is easier and for some - paradoxically - more complicated…

I work in the Institute of Computer Science of Polish Academy of Sciences. Some years ago I proposed to my collegues, who are not bridge players, to start a somewhat similar project. Please contact me Frank if you are interested in details.

Generally: my collegues agreed with me that such research is necessary and innovative, but we had not enough human potential to perform it.

There exist reinforcement learning procedures that can be applied to data base you are collecting.

I see an important aspect of your efforts. About 80% (very roughly) of bridge literature has a didactical aim. The analyzes there, are in some sense irrealistic because the aim is to present a specific position and promote specific solution for such position. Wether it is a position in bidding or in declarer's play/defense.

Teaching is NOT the only aim of research!

In my personal opinion any literature that is oriented for teaching can only be a half-scientific. At best.

Yes! This is controversial and this in fact led to the final risky contract. It basically oriented to play 7-trumps contract - first the shorter 3-card fragment, however - is to be used to ruff their colors.

An obvious line is finessing HJ after the Diamonds lead. Assume W plays H10 after winning the second trick.

Before I put the analysis, may be someone could argue that it was possible to find a sinle-dummy defense for W after the routine play (which in fact was an error) of declarer. Remember that your partner (E) can not give you a true count in Clubs.

To be absolutely precize assume that declarer unblock S8.

Exactly! On the second page I'll try to explain in which sense we have here the “twin motifs”. I also agree with Steve that the second option is better than the first one.

My previous experience was not that optimistic as yours Henry. May be in future I'll be more flexible…

3. If Spades are 3-3 or second Queen drops we have 11 tricks and many chances for 12-th.
4.Of course I play the third round of Spades LOW. If Queen appears from Lefty I RUFF.

My line is intuitive for me. Let's start with the analysis.
1. I put C10 in first trick against amateur and CQ against an expert. (explanation - later)
2. If S has 4 Spades I win easily through crossruffing.

You had to put something high in the first trick.
I start with 3 rounds of Spades. If N follows I drop a Club. If N has 2 Spades I start crossruffing. Real problem is when Queen of Spades drops.
