Hello everyone,
For this last of the season, and as usual, our friend Michel honoured us with his presence. An enormous amount of material, both in quantity and quality, was proposed by the Master. The course almost did not take place, as described by the menu, and by the Master at the right part of this report To begin with, a warm-up with the following position, originally intended for unfamiliar guests, but unfortunately none came.

a) Circe b) Mirror Circe c) exchange Circe (PWC) d) symetrical-Circee) column Circe
a) : the captured piece is reborn on its original square if it is free, otherwise it disappears from the chessboard. b) : the rebirth is on the square of the same piece of opposite colour c) : as the name of the rule indicates, the captured piece is reborn on the starting square of the capturing piece's move d) : the renaissance square is the symmetrical square in relation to the central point of the chessboard e) : the rebirth is done on the original row and the gripping column The mats are models. An educational problem quite easy to solve, even for a neophyte.
The traditional attempt to sabotage the lessons of St-Lazare by the hypercalamitous Parisian transporters has now seized a new twist. Only 4 minutes waiting for the RER B train at the Cité Universitaire station. Piece of cake in appearance. A warning sign all the same: several hundreds of pilgrims clustered on the platform.
All these beautiful people crowd into the train, hug each other like herrings in a caque, then wait. And then what? Nothing happens. Total immobility, which is hardly "Zen" in this case. Ten minutes go by, the damn train doesn't move. An illiterate man vomits borborygmas at the microphone, of which only the word "traffic" is understandable. This bunch of morons use, as we know, this word meaning "illicit trade" instead of the correct term "circulation". After another 5 minutes, I decide that the joke has gone on long enough. I get out and head for the tram, after 20 minutes of being lost.
After hesitation, I gave up the connection to the RER C, fearing a new confusion. So I return to my first... hates, the metro line n° 13. After the most rotten RER line, the most rotten metro line. The rest is a gigantic jostling among a sub-humanity that doesn't need to be detailed. In this magma are various images, ranging from the heroic gesture of Dominique Venner to the comic strip of the 70s, with Berck's "plunge into the rabble".
But rot does not disarm. On the way back (11:45 pm), I try to take the same line 13 again, hoping that the late hour will keep the said rabble away. In quantity perhaps, in quality (antiphrase), no. Two "nique-ta-mère" are waiting near the turnstile for a poor taxpayer jerk like me to pass by (paying) so that they can infiltrate (without paying). I refuse this game, advises an idiot who is hiding in his glass cage, wakes him up, asks him if he finds this situation normal, tells him that I risk being assaulted if I pass without covering the two parasites. He tells me that then he will (perhaps) consider intervening. I answer that with his kind of puppets, you feel really safe.
I decide to capture the bull by the horns, I run into the turnstile blocking the passage behind me. The most pressing mother-fucker shouts and insults me, I answer him "asshole", "underlarva", "human waste" shouting as loud as possible, hoping (naively) for reinforcements. Luckily, the oar just arrives and I rush in before the mother-fuckers have managed to get through. I hardly dare to imagine what would have happened if I had had to wait 5 minutes on the quay.
In the meantime, the fiscal gestapo is blocking my bank accounts and the property manager has just decided, with the help of the "majority" of the co-owners whose votes he bought, an extra 10,000 euros of useless expenses per person. The conclusion is obvious: long live France.
Let the master clerk cover the fairy tale (with the exception of the amusing help-stalemate attached) and present some problems for the summer.
A helpmate #3 with echo-cameleon.
A #2 with try, to be solved in less than 10 minutes. Two #3 with nice mats, the second with sacrifices. The third #3 is a little riddle: how the hell can you break the stalemate without giving too much freedom?
A spectacular but easy #4. Another one more refined, less easy than it seems. Finally two rather simple multi-movers, by the same author.
Have a good holiday and come back in good condition in September. God bless you.
: piece moving on the Queen's lines with the help of a sautoir and being able to go beyond with for limit, either an obstacle or the edge of the chessboard Very aesthetic it becomes more complicated with the third problem which is one of the first production with Chinese pieces

: a piece can only make one move of a length inferior or equal to its previous move The Black King not being in check, the Queen's last move could only be inferior to 3 Kings having changed colour, they can only make one horizontal or vertical move, but not diagonal Very instructive and simple, but destabilizing !

If the e-pawn advances, it puts the Queens in mutual "observation".
The Nb8 has only 2 possible squares but they are forbidden for "observation" of the Nb4.
and pb7, c7 and d7 are unable to advance because of b5 and c5A nice work}

Excellent report.
The commentary on problem 4 makes me irresistibly think of this line from a 1921 film: "My name is Wenceslas Voboroïtchik -- It's not my fault!".
Problem 11 : there are two solutions, but starting with the 2nd blank move (the first full move being identical). We will rather say: "two variants".
Rest well, see you in September, God willing.
A word from Jean-Marc
I'm a bit lost... Wouldn't the masterly rectifications be hairy too? Indeed, our good master evokes "Wenceslas Voboroichik", whereas it must probably be "Wenceslas Vorobeïtchik"? But on the other hand, this character was only born in 1930 and therefore could not appear in a 1921 film, even in a necessarily mute line... This makes me myself mute with anguishing perplexity; perhaps it would be possible to reassure me on this point? Yours sincerely.
La réponse du Maître
Indeed, it is a calami slip. A number has gone wrong, no doubt as a result of the tribulations narrated above. The exact year is 1941, we will have recognized "The last of the six" with (obviously) Fresnay and André Luguet. Infinitely happy to see that this account has readers. At least that's what a literary man would say. With a mathematical background, I would rather say, like Rémy... that this report has at least one reader. Thank you J-M.
