april 3 2007

As the Master indicates in his electronic report, two events marked yesterday's session: the change of premises and the half century of our favourite Grand Master.
Needless to say, the event was carefully watered down at the "Petit Chavignol" where we will now do the digestive part of the course.
digestive part of the course.
As has become the custom, Guy concocted one of his compositions, an Anti-Circé ("tu perds ton sang-froid") very
light on material.
Thanks to both of them.

To start, an extremely interesting study.

1 - White to play and make for the best of it
Cours2007040301 1
W.:   Kg3, Rd6 and e2
B.:   Kh1, Rf4,  Nb4 and h2, pg2

With the equipment present, it is clear that the "for the best" will be reduced to its simplest expression, i.e. a high class rescue.
This will indeed be the case.

The second study was plagiarised by someone whom I am not allowed to name. It is therefore the original that is presented to you.

2 - White to play and make the best of it
Cours2007040302
W.:   Kh8, Rd8, pb5
B.:   Kh1, Be6, Nf3, pf7

Two events:


-- a minor event, the change of office: we are leaving the rue d'Amsterdam after 32 years.


-- an exceptional event: the greatest French problem-composer and solver honours us with a birthday with us.


Wurzburg

Rest for Daniel, but a fairly strenuous 4# to accompany the increasing length of the days. And some simpler previews of a forthcoming article in "Diagrams" on restoration. It is, of course, about the restoration of demolished problems.


Studies: a curious ZZ, embellished with underpromotion, from an already forgotten "Danish wizard". A new case of plag..., shall we say, unfortunate anticipation, certainly a coincidence, involving a famous megalomaniac from across the Channel. And on the contrary, a case of fruitful extension of an idea presented in a somewhat simplistic way. I also give the study by
Mitrofanov's study to underline another "indelicacy" of the aforementioned megalomaniac.


Fischer 8Stein

The game of the day: a masterpiece by a player not yet completely forgotten, the last of his "memorable" book. With one detail, his analyses still hold up, forty years later. We are far from the "monkey man".


Enjoy

A very nice composition based on a hell of a zug.

The last one is an ultra-dynamic position where each side comes out with one brilliant move after the other. Very pleasing

this was the game Fischer - Stein of Sousse

For the chavignolesque festivities, fasten your seatbelts, we're off to a great start

5 - h#2 with Orphans, Rook Huntress and Bishop Hunter
      Orphan : catches the march of the opposing piece that threatens it
      Rook Huntress : moves up like a rook and down like a bishop
      Bishop hunter : moves up as a bishop and down as a rook
      (the notion of up and down is seen in relation to a paper diagram)

B.:   Kf6, pc2, e6, f7 and g7, RHg5, BHe5

b) Kf6 --> h3

very elegant

A little relaxation with the following 2

6 - Helped selfmate 4 moves
      White plays and Black helps him to build a position so that after the 4th white move, Black is forced to checkmate

7 - h#6 patrol chess double maximum
      patrol chess : to capture an opponent's piece, you must be controlled by a piece of your side
      double maximum : both sides are required to make the longest geometrically legal moves
Cours2007040307
W.:   Ke8, pg7
B.:   Kg5, Ra8

Pure and beautiful

To finish, let's have a rail (we are in a railway club after all), here is some Peter Harris

8 - h#3  2 solutions Isardam Einstein
      Isardam : a move that puts 2 opposing pieces of the same kind in mutual control is illegal
      Einstein :  the pieces evolve according to the sequence Q ---> R --> B --> N --> p if they do not capture or p --> N --> B --> R --> Q if they capture

B.:   Kf3, Qb7, Ra4, Bg7

If it's any consolation, he has more in his drawer, so you'd better have a good supplier for your future rails.

Good reading to all, and see you in 3 weeks (April 24th) for new adventures.

Yours sincerely

The master greffier was not so exhausted as he says: still a good job.

Game of the day: this is not a mistake, after all, "de" means "dxe", but "10...Nb8? 11 dxe5" is clearer.

The only mistake: read 25 Qg3 (not Qg5).

Better was 28...Bf6 29 exf7 (29 Ng5)

The move 30 Nh4! which should have concluded the game is missing. It was played 30 Be4 and won 26 moves later.

Bon appetit

a word from our friend Guy


 

Dear Rémy,

A little levity...

With kind regards.

Guy.

Transmuted Kings:, Anticirce
2 solutions


Easy!

Transmuted Kings:
The king, when in check, moves only as the piece or pieces that threaten it. Otherwise, he plays in the orthodox manner.

Anticirce

After a capture, the capturing piece (including the king) must return to its native square: if this is occupied, the capture is forbidden.

Native square:
The native square of a piece is the one occupied at the beginning of an orthodox game by a piece of the same nature and of the same
side.
In relation to the square where they were before being reborn :
 - Rooks, bishops and knights are reborn on the original square of the same colour (e.g. a white bishop capturing on g6
is reborn on f1)
 - Pawns are reborn on the same file.
 (e.g. a capturing White King is reborn on e1)
