the same congregation of faithful was there, present at the service, to listen to the Master's sermon.
As an introduction, the solutions of the two exercises of the last time.
1 - black to play and draw
W. : Kf8 Ré8 Pé6g4
B. : Kf6 Ra7 Ph7
it's just silly
1. ... h5! 2. g×h5 Rh7
1.... h6? 2. e7 Rb7 3. Ra8 Rxe7 4. Ra6+ Re6 5. RxR+ KxR 6. Kg7
The second exercise is reminiscent of Adams - Torre and is therefore quite accessible to the player
2 - White to play and win
W. : Kh1 Qé3 Pa6g2h2
B. : Kh8 Qé7 Bd6 Pç7g7h7é5
Rest for Daniel: no helpmate this time: he had his fill the day before yesterday at the solving championship!
No matting in 2 either. But a 3# festival. A tribute to a great Australian problematic. This country is viscerally anti-French, of course, but it's still Crocodile Dundee's country, isn't it? Everything is prepared in the first two, nothing in the third. Yet it is the latter that is the easiest.
A little joke from a composer from Mulhouse, as a tribute to a faithful listener. All the same, 4 variations without a dual against a King... almost naked. Then a Norwegian composer I know since... the age of 15. Two spectacular ones at last, but very different.
Then three 4#. The first, of great clarity, was often presented in the solutions championship, to give the competitors a breather, and possibly to console them. The second is logical, the third more eventful.
Let's finish, as is traditional, with a selfmate. I'm not leaving the solution, because the key can be guessed, and so you still have to solve... 4 selfmates 2#.
A simple rescue, missed in the rook endgame in a topical game.
A festival of Queen's sacrifices: a modern but pleasant study.
A new Georgian creation based on two ZZ with rook against 3 pawns, one very simple and the other... much less so. Not recommended for a tournament of solutions, but a curiosity that one manages to sense at first, to understand later.
In the first, everything happens on the right. In the second, everything seems to be on the left, but on the best defence, a conversion to the centre is necessary.
See you in a fortnight, on Tuesday 11 February. May God keep you.
Have a good time.

2. Qf3? e4! 3. Qxe4 and we have the same line as the main variation but after Qf2 there is the resource Qd6

a rather impressive study to follow on the theme of 3 pawns against the rook
3 - White to play and win
W. : Ké2 Ré8 Pé6ç4d4ç2

There are ZZ positions
A diversion through the analyses of the Grand Masters

It's a shame to end up like this.
Let's move on to the restoration phase
7 - h#2 vertical Moebius with twin
Gaspar J. PERRONE
W. : Kb1 Rf3 Pé4h2
B. : Kg5 Rd5 Pa6h5
vertical Moebius : To summarise, if the White King was on a1, he could go to h8 or h7. Similarly, if he was on a8, he could go to h1 or h2
8 - serial h#8 with Querquisite (or Ulysse)
W. : Kf3 Nç8a5 Pç5a4 Qub6
B. : Ka6
Neutral : Pa7
Qu=Querquisite (Ulysse) : catches the moving way of the file piece it is in
Here, Qub6 has the Knight's march.
We can note that if White was on the line, there would be mate in 1 move by nPa7-a8 with promotion to Neutral Querquisite!
Small remark: the White King is well in f3 contrary to what we had believed to see at the restaurant. If he was on the f1 square, the problem would be demolished (quadruple variation in the final phase)
A huge piece now
9 - h#2 2 solutions Circe Take&Make KoBul Kings
W. : Kf8 Rh1 Bf1 Nd4 Pb2
B. : Kh3 Rh2 Bg2 Ph4f2
Circé : the captured piece is reborn on its original square if it is free
KoBul Kings : the King catches the march of the captured piece of his camp and keeps it
Take & Make : A capture is necessarily followed by a no-capture move of the same piece
This problem is quite exceptional: it seems that nothing is moving, and yet .....
The last composition is very elegant.
10 - serial self stalemate 8 moves exchange Circe
W. : Kf8 Bç5 Pb7a6
B. : Kb8 Ra8 Bf6 Né7d6 Pb6
Exchange Circe (Platzwechsel circe): a captured piece is reborn on the starting square of the capturing piece's move
This is the end of this report.
See you on 11 February for the next service.
Thanks to the Mestre for the electronic version.
Good reading to all.
Almost perfect account.
Akobia's study: the pawn is on d3, not d4.
Spassky-Bobotsov is 11...a6 (not 12).
In the problem with Ulysses, if the wK is indeed on f3, how come he is not in check when the animal goes to d5? The fairy tale is definitely too intellectual for me.
Enjoy it though.
