They are all 50 %, Ron! by Ron Andersen's mother

My poor little son doesn't know the first thing about analysis!  When I entered the Vugraph Room the other night, I heard him going on and on about how North would finesse the spades and go down in a truly 100% 3NT.
His two esteemed colleagues, the Cartoon-Man Britisher and the Chinese, were sitting in awe, listening to the sonorous
voice of my offspring.

N/S Vul. Dealer West.

Obviously, the Cartoon Man had already worn out both himself and the Chinese, as they (for once) didn't utter one single word.
On the screen, however, the lead was D8 to the King. East shifted correctly to C2, which went to the Queen, which held the trick. The DJ was ducked by West, and D10 was won with the Ace. Another club to the Jack, King and Ace. My son now predicted down one and both the Chinese and the Britisher cowardly agreed.
The Cartoon Man found himself entangled into a long discussion, with himself, as to what would have happened if..... and if.... Luckily he was stopped very quickly, as West was extremely co-operative, and he discarded the S7 on the 13th diamond.
Nobody, not even my otherwise so clever son, could find any way of going down. The loud, clear sound of my son woke up
everybody in the room (even in the bedrooms), "He's going to make it! What a discard!"
The Cartoon Man looked up from his pile of papers and muttered: "What happened?" The Chinese was still snoring.
I just couldn't take it anymore. Honestly, the three-headed monster at the Commentator's desk did not appear to understand very much of this board. Obviously, none of them seem to have my finessing expertise and therefore, they did not see the woods for the trees were in the way!
I left the room, went to see Mrs. Ducheyne in the Press Room and introduced myself as Ron Andersen's mother. Could I please have a Press Permit? "What room and what match?" "Any!" I said, really meaning "every"!
Supported by my stick, as well as my Press Permit, I stumbled in to the Open Room, went alongside the tables, looking at their sheets, as I had a vested interest in the board I had just seen on the screen.
It seemed that half of the field had stopped in a partscore, and the rest were also playing 3NT, many of them going down. The typical play would be a diamond lead to the King, club to the Queen, King and Ace, and another club to the Jack.  Now what?
North has seven top tricks. Many of the declarers did exactly what my son suggested, finessed in spades which was highly unsuccessful.
I have always tried to teach "Ronnie" that all finesses have the same chance of succeeding - i.e. 50% .  What I cannot understand is why my son, with the silent consent of both the sleeping Britisher and the Chinese, desperately wants them to finesse in spades as long as there is an equally good chance in finessing the hearts!
You take your two top spade tricks, and if the Queen drops (like here), everything is OK. If the Queen is unwilling to yield, you finesse with the H10, and your chances have improved significantly.
I must admit that I do admire the one player in the room who played just like I have suggested, the compatriot of my Danish mother, Soren Christiansen, who is much more clever with his finessing than my son, the Cartoon Man and the Chinese together.
He scored 14 IMPs to Denmark, as the Austrian North in the other room was more in accord with my son, and found an excellent way of going down three against Peter and Dorthe Schaltz.
"This board is interesting with a blind club lead from East." says Ron. What do I know about squeezes and endplays? I may ask him about it one of these days. But I am certainly not going to ask the Chinese.
I cannot possibly understand whatever reply he might have and I don't think it would be a good idea to ask the Cartoon Man, for he is likely to lead me into a deep analysis that will go on and on for ever and ever and a day.
