It's a great responsibility entrusted by the Master to compensate the deficiencies of the cybernetic assistant, the task will be hard.
Some dates to start
The next lesson will take place on 8 January.
the annual world problem-solving competition will be held, in theory, on Sunday 27 January.

A high-quality assistance for this fairy session in which we will however note the absence of Abdel and Pierre who will have to present a signed word of apology.

To begin, a small warm-up with a very beautiful Circe.

1 - h#3
helpmate : Blacks plays and help White to mate them.
Circe : a captured piece reborn on its original square if it is free, otherwise it disappears (not the square, the piece, of course).

Jean-Pierre BOYER &
Problème, 1968

h#3 Circe(2+3)

Very clean and elegant

Now that you're warmed, let's move on to Take & Make. If necessary, bring the appropriate fuel for the maintenance of the heating system.

The fairies will be handled by the master graffier. Let's be satisfied with the Christmas exercises.

Helpmates : ( temporary ) end of the "Jones festival". The first one is the easiest. A Grigorian 5-piece to rest. A
long easy helpmate, for once. A recent one, by V. Tchépijny, who is now 73 years old.

Directs : a three-move of the same, but composed 40 years earlier. It includes a formidable trial, with a thematic focus as well. Two
others of the same: restful miniatures. A long (but easy) problem of the recently passed away "Vuk" (the "wolf"). Finally, a
2-moves from a recent judgment, the particularity of which is the following: having solved them all, it's the only one that has pleased me
, but he only received a third honourable mention. It would be better not to ask me to judge problem contests !
I was only asked for it for study competitions, and already, it is not sad !

selfmates : another underclassified problem, a brilliant s#5 by Mikan, even better than the one selected for Rhodes,
where it would have wreaked havoc (I would have been spared, having seen it this summer!). And three others much simpler, two of which

Retros : a tribute to our national grandmaster, who honours us with his presence: two super PGs and a classic retro, you must meditate carefully.

Speaking of exclusive chess : a particularly "intellectual" Turnbull, already presented a long time ago: it is the only
2-moves I know whose solution lasts... 4 moves !! Then a masterpiece of... who ? You guessed it.

Regretting not having presented a reflex this evening, I remembered this delicious problem presented to Messigny this
year (all the more delicious as I was the only one, by chance, to solve it, even if I had to not resolve 3 PG). And a cyclical reflex
2-moves rather curious.

Have fun and Cherry Mistmas, as Pierre Bretagnolle used to say.


2 - h#2 2 solutions
Take&Make when a piece captures, it plays a complementary move by using the moving way of the piece it has just taken (a kind of posthumous homage).
this additional move should not be a capture
2 solutions : there are 2 distinct lines of play that satisfy the conditions

Very nice diagonal/orthogonal echo

A small visit to the bestiary.

3 - self-helpmate 2 moves with , , and
self-helpmate : White plays and is helped by Black and, at the last move, Black finds himself in a position where he is forced to checkmate White.
AntiCirce : the capturing piece reborn on its original square if free, otherwise capture is illegal.
Grasshopper : piece moving on the Queen's line, which moves only with the help of a hurdle and lands just behind if the square is free or occupied by an opponent's piece.
Leo : piece moving like a Queen without capturing, but like a Grasshopper if it captures.
Lion : Grasshopper not limited to the square just behind the hurdle. Of course, the path must be free.
Nightrider : Extended rider
it can be noted that the renaissance square of a fairy piece is the promotion square, in this case the 1st row on the Anti-Circe capture column.

Good luck, but it's worth it.

Now, you have to get your Scottish drink out of hiding and pour yourself a good shake because here is our friend

4 - s#3
Selfmate : White plays and forces Black to mate them.
MAFF : literally "Mate with A Free Field", in other words for the uninformed : checkmate = check with only one free square for the King in check

Still with our Scottish friend, exclusive chess

To relax a little, we give up Turnbull and move on to a serial moves problem.

6 - series helpmate 37 moves

To be mated, Black bring back white pieces on the first rank thanks to the Circe rule

This problem, as you can imagine with all the pawns near the promotion is a double AUW (AUW = the 4 promotions).

Back in the bestiary for half-time

h=2,5 AntiCirce Cheylan
b) 🨢g2=♘g2
🨢g2, 🨨a1: Nightriders

For those unfamiliar with this particularity, Kf1 is not in check with the Cheylan type of anti-Circe because the rebirth square of the B is f1.

For the restaurant part, our friend Guy presented two of his works, one of which is in gestation, let's not disturb this always delicate period.

It remains to wish you good reading and a happy holiday season. No doubt we'll see you tomorrow for the corrections.

Yours sincerely.





I think the Leo, when he takes, does it like a lion, not a grasshopper. If I say true (also false), Guy does not
will not fail to react presto.

I can't think of anything else to complain about. I did not keep the positions but if by chance you don't get solutions (impossible...?) you
can ask for confirmation or even a tip from the Grand Master Greffier, who has just produced a new standard.
