the greffier's paw
After a short walk to get back into shape (this is the positive side of transport strikes), the greffier, having had his brain irrigated, is in full possession of his means.
The audience at yesterday's session was sparse to say the least, but attentive and responsive despite the low ambient temperature.
To begin the hostilities, a very pleasant study with a very aesthetic solution.
1 - White to play and draw
W.: Ke6, Bh3, Nf7, pa7, b2 and b5
B.: Kb3, Bg1, Ne8, pe2 and e5
It was to be expected: the strikers were going to have a field day, symbolically starting their sabotage in the middle of the Saint-Lazare course.
A "double Indian" helpmate which we can be surprised that between Sam Loyd's time and ours, it hasn't already been done. A very easy selfmate 3# by Selivanov (a very dear friend of the organiser of Messigny).
Three studies: a nice draw from the cold. Enough to fuel the current controversy between Y. Bazlov and S. Didukh (see the excellent article of "Charpentier" on France-Echecs). And a mate in 10 moves which Didukh's study irresistibly reminds.
The day's game was typical of this former world champion: very cautious and then, suddenly, a paw in the form of a well calculated provocation. And an inevitable "quality sacrifice". As our master greffier would say: "One sees the Black player, still young, give a few cat-like paw strokes. Later, with age, he will turn into a python".
A small preparatory move, a second preparatory move; an extremely brilliant move and hop the draw board appears as if by miracle.
A second brilliant study.
2 - White to play yand win
W.: Ke8, Ba4, Ne5 and h6, pd3
B.: Kc5, Bf8, pf2
A beautiful work
the position of the 3rd study reminds a bit of the trenches and the solution a period of bombing.
3 - White to play and win
W.: Kd1, Qh1, Rb7, Nb3, pg6
B.: Ka2, Rb2, Nh3 and h4, pc3, d2, d6 and f3
A beautiful fight on the razor's edge.
The day's game sees the still young blacks give a few cat-like pats. Later, with age, he will turn into a python.

For the restoration part, a good catch of cabbage with the King (or Kings) in disguise.
To try to summarize what I retained, here are some elements:
1 - a piece of a side is a King in disguise
2 - the piece having the appearance of the traditional King can be captured if it is not a disguised King
3 - a pawn cannot promote itself into a King
4 - a pawn cannot advance 2 squares if it is a King in disguise
5 - castling is possible with the usual rules if these are checked when the rook is a disguised King and
if none of the pieces (R and T) is a disguised King, there is no restriction
A simple position to make the hand in the Japanese way (composed by Yamada)
5 - h#1,5 Kings in disguise 2 solutions
helpmate 1,5 moves : W plays, B plays helping W, W checkmates
B.: Rh8, pe7 and h6
The ph6 can't be a King in disguise as you might have guessed.
a bit more material now that you are hot
6 - h#1,5 Kings in disguise (Wakashima)
W.: Kg6, Bh5, pe5
B.: Ke8, Ra8, pd6
The pd6 is certainly not a King in disguise
The continuation of the warm-up
7 - h#2 Kings in disguise (Yamada)
B.: Fh5 and h6, pf7 and g7
A little retro analysis shows that f7 and g7 cannot be Kings in disguise because of the obligatory passage of the White King on the
And here is what a Michael in great shape does with the Kings in disguise
8 - h#2 Kings in disguise (Michel)
W.: Ke1, Rh1, Bb1, pc2
B.: Ra3, Bg5 and g8, Nh7, ph2
A bit of retro here too to determine the possible moves and give an indication of the Kings in disguise.
Good reading to all.
The next session will be magical and will be held on December 18th
In the absence of any real mistakes by the greffier, I am obliged to cut the hair of c...amels in four.
Game of the day: "wins" has become "gangne": the greffier was thinking of the gangue of gneus-gneus. The strikers again.
16 Ng5 Nf6 17 Rd1 rather than Re1.
"Switchback" rather than "switchblack". Rugby again.
20...axb4 : maybe not white advantage if Black does not fall into the trap 21... Rh4??, but in any case nothing of the
Black's advantage diagnosed by previous commentators.
And it is, of course, White who resigns.
Have a good read and enjoy
the greffier's paw (continued)
Still one pocket left, like last time.
A short passage through the Take and Make
9 - h#2 T&M
T&M : a capturing piece must make an additional move with the captured piece's march, with the restriction that not capturing
W.: Ke7, Rd4, Bb6 and e6, Nc3
B.: Ke5, Rf8, Bh2, Ne8 and g3, pd6, d7, f3 and g5
b) pg5 --> d2
Finally, a little Anti-Circe with Grasshoppers
10- - h#2 anti-circe with Grasshopperss 2 solutions
anticirce : the capturing piece returns to its native square if it is free, otherwise the move is illegal
Grasshopper : piece that moves like the Queen and needs a sautoir. It lands just behind the sautoir. The "landing" square must be free or occupied by an opponent's piece, otherwise the move is illegal
W.: Kg7, Rd8, Ba8, Ga1 and c3
B.: Kd4, pc2, c4 and d2
With my apologies.
