The heroic report of the nocturnal Greffier.


A lot of material for a reduced audience on this fairy day, since only our Grandmaster was present in addition to Daniel and me.
First of all, and if my memories are correct, a happy birthday to the Master on this 13th December.

To start the festivities, a rather old problem verified by a human being and not by a machine.

1 - #2 with Grasshoppers

The few beautiful Grasshoppers of Monréal will not be able to do anything against the assaults of White.


Master's words


Two months ago, I was presented with the following problem: to invent a legal position in which the White King is double-checked, but responds by checkingmate, without taking. I was able to appreciate the difference between a solutionist and a composer: I spent about an hour and a half finding such a position, whereas A. Onkoud took barely more than a quarter of an hour to discover... the same as me! But it's not the only one. Rémy found one with another battery, Grégo too. I refrained from bothering our Grandmaster with such trivialities. Attached are some examples. 

Tribute to the great Fadil for Daniel, but also a few other entertaining helpmates for... the whole family, gathered together on New Year's Eve. Including a very easy 2-moves aristo. 
Among the directs: a surprising #2, a nice logical (easy) #3 from the famous Russian-Ukrainian duo. Then two examples of other giants, illustrating modern themes but, through their immense talent, in a form that is not boring. 
Finally, two #6 from another Ukrainian giant, which have something in common and should therefore be enjoyed together, or in concert, if one prefers. 
A fairy tale with the master clerk....   
Merry Christmas and see you for a "normal" course in a month's time on Tuesday, January 8th. God bless you. 

A new genre now, at the fairy course, of course : the double-step

2 - h#1 Double-step 2 solutions

white Pc2b7b6 Rg6 Bd1c5 Kh5 black Pg3f4c4d5d6g7h7 Ke2 Rf7 Sf6e6 Bd7
h#1 Double-step(7+12)
2 solutions
Double-step chess :a piece (or pawn) that is playing is required to make a second move. The first move cannot be a capture.
The restriction of the grip on the first move is quite clear from the diagram.
Small look :
The Tg6 is pinned because of pg7 - g6 - xh5
The Black King is pat if we do not consider the other pieces of his camp.
It's up to you to find the rest

It's an interesting genre.

A small return to the old compositions with the next one which dates back to 1974.

3 - #2 with Rose

Tournoi Olympique, Nice 1974 - 3° Honor Mention

Rose : Extended knight in round ( Rob8 - c6 e5 g6 h8 or - d7 f8 or - d7 e5 d3)

There was a tough contest; it had to be solved in 1 minute. Needless to say, we didn't succeed.
an incursion by Grasshopper 2 which landed 2 squares after the sautoir

Very interesting.
The final picture is ideal.

 Small diversion by the parrain Circe

#2 Parrain Circe(9+5)
Parrain Circe : a captured piece remains suspended above the capture square and then makes an equipollent move to the one of the piece which plays immediately afterwards
Two elegant moves, but only one is good.

Big headache with the vertical Möbius.

6 - h#2 vertical Möbius

vertical Mobius : to make it simple, glue a chessboard on each side with a1 glued to h8, a8 glued to h1, h1 glued to a8 and h8 glued to a1

Very disruptive this ribbon.

Our Peter Harris is back with a composition of which he has the secret.

8 - serial h#13 with twin
white Pc7d6e5 black Pa5 Kf4
black ultra-Maximum
opponent's pawn Sentinels
b) + Transmuted Kings
a) black Ultra-Maximum : black must MANDATORYLY play the geometrically longest move.
opponent's pawn Sentinel : each move of a piece defecates an opponent's pawn on the starting square of the move
b)+Transmuted Kings : the King catches the march of the opponent's piece which puts it in check for the time of the move.

Take a deep breath with the Anti Circe

9 - serial h=10 coups AntiCirce
sh=10 (12+12)
Anticirce : the captured piece is reborn on its original square if it is free, otherwise capture is illegal.

A small PG Single Combat now

PJ 10 Duel (Single Combat)(16+16)
Single Combat (Duel) : a piece which has just made a move is obliged, on the next move, to continue playing until it is legally impossible to do so
Very well built.

Annan chess is very particular, and here is a PG to show it.

11 - PG 9 Annan

PG 9 Annan(16+16)
Annan : a piece is pushed by the piece of its camp which is immediately behind it and catches the characteristics of it during the push.
example : ph2xh7 or a2Xa7

Une bonne prise de tête

Mirror Circe is also a particular rule

12 - hs#2,5 with twin
Cedric C. LYTTON

Mirror Circe : a captured piece is reborn on the original square on the opponent's side
. example: gxf3=Black Knight b1

Now a neo-strausskanian rule, the super pine (to be linked with the Monréal's Grasshoppers).

13 - h#2 super pin
Phénix 1990 (v)
2° Honor Mention
white Qa1 Pg4h4 Kg6 Be2 Sf5e5 black Pe4c4b6 Kf4 Rb1
#2 Super Pin(7+5)
Super Pin : priority to pinning over all other considerations.
A check can therefore be avoided by nailing the piece that is checking.

14 - h=2 Rönnauer chess duplex
Andreas THOMA

h=2 duplex Rönnauer Chess(2+2)
Rönnauer chess : when a unit is observed by an opponent's unit, it catches the march of the opponent's unit during the time of the observation.

b4, b5: Vao

Vao : Bishop needing a sautoir to capture
Locust : Grasshopper eating its sautoir (which is therefore inevitably an opponent's unit)

white Pa7c7e7g7h7g4d5 Kd3 Sh1g8 LIf5 black Pd7g2f2e2c2b2d4 Ke5 Bb8 LIa1h3 Rd8

white Pb6c7 black Qa8 Ke6
b) Ke6-->e3
Anti-Andernach : a move without a capture changes the colour of the playing piece.
Ultra-Patrol : a piece can only move (and therefore also capture) if it is observed by a piece of its own side

Good reading to all, and see you on January 8 2013.

Happy Holidays to all

Remarks, (in the absence of corrections)

Thank you Rémy for "thinking about it". When I said on Tuesday evening that our master greffier had a phenomenal memory... Just think about it in two years, when it will be erotic! Even more than the "super-pins"...
Our grandmaster was there, indeed, and showed us a work which seems to be in the 2001-2003 album, the last one published, given the dynamism of the problemists, who know how to take time, and the only one I don't have. To be continued.
All this to say that I don't have much to say, the report being almost immaculate. At least as far as I remember, because I don't keep the fairy tales. At most I would have said "extended grasshopper" for the Lion. But that's no reason to shut up, as you know...
Relax well, don't drink too much and come back on the 8th of January.
