Rémy, our valiant greffier, being excused, I have the honour to write this modest report.
The attendance was respectable, with the permanent hard core, composed of Daniel, Pierre, and the substitute. But also for varying lengths of time Michel, our double World Champion, and also Jacques, an Oriental - and Norman for the occasion - IM, my favourite co-author, and a new guest who gave us the pleasure of a short but dynamic appearance.
First of all, a beautiful study by Yuri Bazlov which offers starter, main dish and dessert (the diagrams are at the bottom of the page, in the same order)

A word from the boss
Two classic helpmates and one recent twin of which only a part is difficult.
A few directs to prepare for Messigny. Two small two-moves, well, not so small. Ivanov's 3-moves is especially surprising. Shinkman's 5-shot is a classic often shown in a wrong version (with the wK in h1, there is a major dual). Finally, a long and fairly easy strategic problem: imagine what you would do without the f4 pawn.
And for the insomniacs, a great (as always) Gamnitzer. Click on "practice": I did not have the cruelty to delete the solution.
A curious ballet with two dazzling moves by the future Queen. An amusing fight of another Russian to, following an ingenious defence, transpose (more or less) into Larsen-Miles 1979. To which I add a study by Réti from a forthcoming article in tribute to Halberstadt, about a digression on "tolerable" duals.
A Krikheli marvel where you have to play eight (!) moves from the White Rook before bringing your King closer! This study includes a horizontal-vertical echo, which is often found in modern compositions.
Today's game involves an extremely original mind, which was always contested even (especially?) in his own country. But, as we know, you can tell a genius when all the fools are ganging up on him.
The end of Sotchniev's study reminded me of a Knotek problem in which the mate in question is tripled. In the restaurant, I took the opportunity to mention, still on the subject of Q+B versus King, the comparison between two problems with three identical mat pictures, one by Wheeler already presented in the past, the other published three years earlier by Havel, with a less good key but an additional variation. Which one do you prefer?
Have a good time. See you on 13 May and God bless you.
Followed by another beautiful piece by Alexei Sochniev, which shows a surprising finale.

A classic by Iosif Krikheli, to sharpen his technique with some "echoes" as a bonus:

Today's game shows a fiery, but precise game

At Pierre's initiative, the railway workers from Batignolles went to dine in the eastern part of the capital; an old station buffet to keep their bearings. The cheerful atmosphere created by the productions displayed on the chessboard was not tempered by the abundance of liquids on the table. On the contrary. The owner of the place, his team, as well as his son, a former French youth team champion, took part in the party, to the delight of the guests. A bistro that I warmly recommend:
And as a testament to the courage of those present, here are two of the pieces shown by the Master, who was in a light mood:
The Problemist Supplement 2008
W. : Rc5
B. : Kh3 Pe2
No White Kings
Transmuted Kings (a King, when in check, catches the march of the threatening piece)
Masand (A piece, when it gives check, changes the colour of all pieces - except Kings - that it threatens or controls)
Helpmate in 3 moves
Charles H Wheeler
Unfortunately I do not know the exact source, which seems to be 1905, but this problem was reproduced in
« 777 Chess Miniatures in Three, E. Wallis 1908 »
W. : Kh4 Qa7 Ba2
B. : Kf6
Mat in 3 moves
I add this chameleon echo composed with my favourite co-author:
Jacques Rotenberg & GS
W. : Ke1 Na8
