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.

Dear Discutants and other Readers interested in this problem. I put possible hands of declarer on the 4-th page of article. Please make some comments and/or further analysis (including “deep finesse”).

You are right!. Unfortunately - from this viewpoint, and fortunately - from routine bridge approach:

POLISH PNS NAT assumes openings from 5-card colors.

Consequence of this assumption is very large number of holdings, which qualify to 1C opening. This is why our primitive natural system is often called NAT(C).

Your both S's hands Rainer do not convince me.

1. ? K9x ? xx ? AKJxxxx ? K a. Natural bidders enters on the second hand with 12+hpc, since they do not use drury. b. If DQ will not drop (assuming it is not in hands of N), declarer can have serious problems.

2. ? A8x ? xx ? AKJxxxx ? K This is better. But still he must consider first lead in Spades, which makes communication problems. Also CA first lead will be difficult.

I will add few pages to this article to explain some non-obvious points. But you have claryfied the basic “surprizes”!
