Sorry for the delay in writing the report, but a busy schedule has delayed the writing of it.
The electronic version written by the Master is of course included at the end of this message, accompanied by a photo with explicit content!
For this session, we were delighted to welcome back our friend Pierre, who is in better shape than ever.

The Master, to begin with, proposes a study which obtained a 2nd prize and whose diagram has the aesthetics of beautiful (and good) compositions

1 – White to play and draw

K7/1r6/2b5/3k4/8/5N2/7P/7B
W. : Ka8 Bh1 Nf3 Ph2
B. : Kd5 Rb7 Bç6
= (4+3)

To help you out a bit, you have to get to a Bishop vs. Rook endgame, and watch out for banana peels!

The following position is quite remarkable and will appeal to the "normal" chess player: great tactical play and great riding.

2 - White to play and win

8/P3nKP1/4p1pk/6p1/5bPq/8/8/8
W. : Kf7 Pa7g7g4
B. : Kh6 Qh4 Bf4 Né7 Pé6g6g5
+ (4+7)

As with the previous one, it is well worth a look.

For the game of the day, a highlight : the Karpov-Nikolic game

3 – Game of the day
1 d4 Nf6 2 c4 e6 3 Nf3 Bb4+ 4 Bd2
4 Nc3 falls directly into a Nimzo.
There is also Nbd2
4 … Qe7
In addition to this continuation, there is a choice between 4 … Bxd2+, a5 and c5
5 g3 0-0 6 Bg2 Bxd2+ 7 Qxd2 d6 8 Nc3 e5 9 0-0 Re8 10 e4 Bg4 11 d5 Bxf3 12 Bxf3 c5 13 Rae1 a6 14 b3
The threat was b5
14 … Nbd7 15 Bg2 Rab8 16 a4
Block the Queenside to get hands free on the other side
16 …Qd8
Prevents a5. On 16 ... a5 White plays 17 Nb5
17 Qd1 !

Some helpmates: the ambush is in the spotlight in the first one. Helpmate 3# has a special feature: the special "Fritz" problem analysis engine dries on the twin (a), which a normal human solves quite quickly (although we recommend starting with (b)). The 4# helpmate is of a kind I don't normally like, with groups of units only used by one or other of the triplets, but I must admit I was seduced.
 
A complete variety: a 2#, a 3#, a 4# and a 5#. The 2# is easy and pleasant, but with a false lead. The 3# is tougher, with many variations. The 4# can't be difficult: Black has only one or two mobile pawns! The 5# is everything one could wish for in a logical problem.
 
Appeal to the owners of powerful computer instruments: this 20-move selfmate is very easy, it can be solved in 5 minutes. But the question is: what is the bNa8 for? I specify that I do not know the answer.

 
A few months ago we saw a rook versus bishop duel. But if a pawn is added to the bishop, it is a different matter. The symmetry is only partial, adding to the magic.                    
 
A Queen's duel? No need for a fuss. A black bishop is watching them

Today's game looks like a massage, but a closer look shows that things were not so simple. Don't miss the finesse of the black "h" pawn: depending on whether it is on h5 or h6, White chooses a completely different method... yet...
 
See you in a fortnight time on February 7th if God wills.

Have a good time

Une vue d'ensemble de la partie, à présent... mais au fait, avez-vous deviné qui est le joueur ? Réponse au prochain compte rendu.

A very interesting and multi-functional move: prevents Ng4 or h5 and therefore allows Re3 without fear, and keeps an eye on b3 in case of Qa5-b4
17. … Re7 18 Re3 Qa5 19 Rfe1
The move f4 will come, but it is necessary to take its time and gain a little space before
19 … Kh8 20 Bh3 Rg8
Disturb the push f4
21 Kh1 Qd8 22 Qd2
Ng4 being prevented, the Queen can return for the push on the Queen side
22 … Nh5 23 Ne2 g6 24 a5 Ng7 25 Bxd7 Qxd7 26 f4
At last !
26 … Rge8 27 b4

27… cb 28 Qxb4 f5 29 Nc3
29 c5 immediately was interesting

29 … dc 30 Qxc5 ef 31 Nxf4 fe 32 Rxe4 Rxe4 33 Rxe4 Rc8 34 Re7 Qg4 34 Qf2
29 … ef 30 gf fe 31 Nxe4 Qf5

Ne4 is attacked and furthermore pinned, so there is only ….
32 c5 ! dc 33 Qc4
If the Queen had been elsewhere, in g4 for example, then Qxc5 would have been possible, so the move played is the only correct one
33 … Qxf4 34 d6 Re5 ?
34 … Rd7
35 d7 Rd8 36 Qc3 h5 !?
36 … h6 ?! 37 Rf3 Qg4 ! 38 Rf7 Qe6 39 Nf5 Nf6 !!
37 Rf3 Qh4 ?
37 … Qg4
38 Rf7 Rg8 39 Qc1 ! g5 40 Ng3 Rd5 41 Rf6
With a small threat
41 … Rd8 42 Qb1 !
Taking advantage of draughts
42 … Kg8 43 Re8+
43 Rh6 is less spectacular but just as effective
Here blacks lay down their arms

A great fight where the blacks were up to the challenge

For restoration, a small tour by Take&Make

4 – h#3 Take & Make
Éric HUBER
T.T. Die Schwalbe
1° Prix

8/8/6R1/2PP2p1/BB4b1/6kn/3r4/2R3bK
W. : Kh1 Rg6ç1 Ba4b4 Pç5d5
B. : Kg3 Rd2 Bg4g1 Nh3 Pg5
h‡2 (7+6)
Take & Make : when a piece captures, it is required to make a move immediately that adopts the march of the captured piece

Good headshot!

Then a passage by relativity

5 – serial h#9 Einstein
Lee POISSANT

2Knk2n/8/4B3/4P3/4P3/3pP1P1/3pRP2/3P4
W. : Kç8 Ré2 Bé6 Pé5é4é3g3f2d1
B. : Ké8 Nd8h8 Pd3d2
sh‡9 (9+5)
Einstein : when a piece captures it progresses in the hierarchy according to the cycle p-N-B-R-Q and reversely when it plays without capturing

(Re)Good headache!

The dessert is Chinese.

6 - h#3 with chinese pieces
Stephen EMMERSON

2M5/1p2u3/1v2U3/2Vk4/6pK/8/8/8
W. : Kh4 MAç8 PAé6 VAç5
B. : Kd5 Pb7g4 PAé7 VAb6
h‡3 (4+5)
b)-g4
MA=Mao : Creeping knight (one rook step + one bishop step)
VA=Vao : Bishop needing a sautoir to capture
PA=Pao : Rook needing a sautoir to capture

Very elegant with the twins well in symmetry
  
It remains for me to wish you a good reading and to give you an appointment for the next session on February 7th, and probably before for the hair concerns highlighted by the Master.

Yours sincerely

Le greffier

Master's rectifications

Variation 29 ... dc 30 Qxc5, quite deterrent is the intermediate 30...Rc8! followed by the capture in e4. 

 
In the one of the 36th move, a move has been forgotten, it should be read: 36 ... h6 ?! 37 Rf3 Qg4 38 Rf7 Qe6 39 Ref1 Nf5 40 Nf6!
 
The report seems to me excellent by the way. Good reading
