less participants than usual for this penultimate session of the Master's course, the railwaymen having gone to do Resistance in Vichy or some other place where one only drinks water and the others waiting for the last course of the season next week to express their chess next week to express their chess verve.
The next one is therefore, as I just mentioned, on Tuesday 5th June
Reminder of the entry code: 831b
the electronic version of the Master and Guy's contribution to the club's fame accompany this textual version of the version of the report.
As usual, many thanks to them.
To begin with, a little study where we ask ourselves how to survive.
1 - White plays and keeps his head above water.
W.: Kg2, Bh1, Na2
B.: Kd4, pb3, b5 and b7
Some problems for holidays, few helpmates in Daniel's absence.
Four studies, including a trompe-l'oeil given at the French Solving Championship the day before yesterday.
Two short and extremely instructive games: a quick defeat of a very strong player may simply be the result of a fine error of learning on a key variation supporting the whole building.
Finally a witty and ingenious reflex.
Fairy session in a week.
Enjoy your meal
The following is a study that caused some problems at the last French Championship in Messigny
2 - White plays and also keeps his head above water
W.: Kh3, Ra5 and b4, Ba1
B.: Kh1, Qf8, Be1, pe5, f5, g7 and h5
A lot of twists and turns for this very nice position
A short trip to Norway for the next study.
3 - white plays and gets away with it
W.: Ka6, Bb1 and g7
B.: Ka8, Bf1 Nb5 and b2, pb6
There is some piece in immediate grip and some piece potentially in grip, it will require good footwork.
4 - for once in this session, white to play and win
W.: Kc2, Qd7, pg4, g5 and h7
B.: Kg6, Qe5, pa2 and d2
Very interesting mechanism.
the two games of the day are short but good

After these two short but agitated fights, let us pass to the Chavignolais amusements which took place initially on the terrace, because of the success of the place and the incompetence of the person having noted the reservation
To warm up the brain in this situation, a little colouring.
7 - colouring the pieces
Ke6 and f8, Qg8, Re8
Reminder on the Anti-Circe : the capturing piece is reborn on its original square if it is free, otherwise the move is illegal.
Another amusement to continue the warm-up.
8 - white and black retake their last move and the position becomes a helpmate 1 move
helpmate : Black play and helps White to checkmate him
W.: Kg2, pd5 and e3
B.: Ke4, pb3
9 - serial h#3 with general Rooks
serial helpmate 3 moves : black plays 3 moves in a row and white checkmates in 1 move
General rooks : monochromatic rooks
W.: Kc6, Qg1, GRc5 and g4
B.: Kd4, Ne3, GRa3
b) Anti-circe Calvet
c) Anti-circe Cheylan
Anti-circe Calvet : you can capture on your own rebirth square
Anti-circe Cheylan : the above capture is illegal
10 - serial #5 with Equihopper
serial direct : white plays the n moves in a row until mate
Equihoppers : the piece jumps geometrically symmetrically with respect to a sautoir
W.: Kh8, pc4, Ee1, e5 and h2
b) c4 --> c5
Enjoy your reading and see you next Tuesday for the participants of the fairy tale and Wednesday for the others.
A detail concerning the 2nd study: in addition to Messigny's competitors, two former French champions, a GMI and an MI, also suffered yesterday, Wednesday.
The 3rd study takes place in Finland rather than in Norway (and the previous one was Swedish!). And the second Black Knight is on d2 (not b2).
First game: Black's 11th move is missing: it is 11...Nxe4
Second game: the 14 Qc6 variation ends with 18...a5, and 16 BxB is too much (16...Rxc8 and d5 falls).
And the 22nd move is missing: 22 e6 Ne5!
The parenthesis of the 23rd move must be read: (23 ef Rf8 24 Nf4 Nf3+! 25 Bxf3 Bd4+ but better is 23 Bh6)
A word from Master Guy(ms)
Here is to celebrate this new course of great value, "the unpublished for Marquis".
I will spare you for the occasion the fairy condition "Republicans", far too provocative.
However, on the eve of these new elections, I couldn't help proposing the "Köko" condition, which might win your vote.
This problem combines a classical Indian theme in the first solution, with an "anti-Indian" (?) in the second, where the back piece of the "Köko battery" is hidden, not behind the White King, but behind the Black King .
A move is only possible if the piece making it is in contact with another piece.
White : Ka1 Rb1
Black: Ka8 Nf7
Helpmate 6.5 moves (White starts, and both sides collaborate so that White mate on his 7th move).
