Click in the right part of the chessboard to move forward, left to move backward... or directly on the move in the solution
As is often the case, a few strikes have disturbed the lesson and are likely to disturb tonight's meal in honour of the 64 springs of the Master.
A fairly crowded assembly had braved the weather and the strikes to enjoy the traditional end-of-year festivities.
In addition to the hard core, the Grand-Master Michel was present to animate a little the evening.
All heavy with a few breaks.
Special neuron defrosting.
Desperate to translate a diagram neatly in text, the greffier takes the liberty of providing an attachment which is only really legible if the 1st chess font is available.
Positions 13 and 14 were presented during the dinner between some of the positions outlined by Master Guy
See you tonight for the brave who dare to face the snow and the strikes.
Have a good reading
Yours sincerely

1 - ser-s#7 Circe with neutral pieces
George SPHICASThe Problemist, 20024th HM
Master's word
As usual for the fairy session, the retransmission in Chess Base is very limited, the neutral or even semi-neutral pieces, camels, nightriders and other animals do not pass easily. Let's limit ourselves to the ortho/heterodox problems.
Three helpmates, the last one likely to take a little time. A mat in one (!) with a trick, which was presented on a forum and variously appreciated. I'll leave the solution, but advise you to hide it for a few minutes. The other direct mats are normal: a #2 with a few false leads, two #3 in the same competition (the highest ranked is not the most surprising), and finally a #9: a real festival.
As a gift for Christmas, a very easy selfmate #5, which is surprising when you know the name of the author. The Marquis took less than five minutes, but you'll probably do better. A traditional retro, not very difficult either; the genre gets lost, that's a pity. And two PG's, one of our favourite "chti", which accumulates masterpieces with ease. Of the two, I find the Finnish one the least easy.
See you the day after tomorrow at the "Beer Academy" for the 64 years of your canister Master, despite the usual attempt to sabotage the transport workers. Then, for those who will be excused (letter from the parents indispensable), on January 5th, God willing. Good luck and Merry Christmas.

In Example 4, the published diagram was wrong. I, on my own initiative, changed the wPd3 into a white Rook. Note that in Glasgow Circe, a white fairy piece is reborn in the seventh.
In 6, it is simply a (semi-neutral) Rook in d6.
There are 2 solutions in 11 and 13.
No other visible error (but I don't have the diagrams anymore).
Thank you to all those who have done me the great honour -- and pleasure -- to show some interest (whether they were able to come to the Academy or not) in the symbolic milestone that their devoted canteen master has just passed... who will meet everyone on January 5th.
Merry Christmas.
