## a word from the boss

An ample harvest of helpmates to last four months. The theme of the first h#3 is very explicit. Only the last h#3, one of the twins of the h#4 and one of the solutions of the h#5 seemed difficult to us..

Three #2 spread over nearly a century and a half. The #3 are more recent. The last one will probably be a surprise for many. We end with a little Lepuschütz festival (#6, #7 & #12).

A part of the fairy course concerning Andrade's trick (which was more successful than expected), then the

*growing men*(2 of the 5 problems have already been presented in December). Obviously, some moves don't pass and must be in notation...It only remains to wish you an exciting summer, hoping that you will bathe in

*beauty*in all forms...## Daniel's word

Sorry for the very late reply, but between the football World Cup and the "household chores".

First of all, and although the Master has already shown this position in his report, I would like to review the problem of B again. Andrade (1958) which made us suffer so much.### 1 - how many white moves to allow Black to escape #1

Hoping to provide an unambiguous statement :How many white moves allow blacks to escape mate in 1 move? ?

For example 1:Qa5 ? is not such a move, because on all Black moves, whites will have a checkmate possibility in 1.

The answer is 6. it's up to you to find them.

I see that the Master has provided in electronic format all the positions that he was able to enter..

I didn't write them down (busy as I was looking for them, sometimes even understanding them) and I don't plan to look for them to provide them because I'm just as incapable of reinventing them as I am of remembering them (on this last point, I'm ashamed)..

I tested on Abdurahmanovic/Mihajloski's h#6 and it took me almost 45 minutes, even though I had seen the solution during the course and had appreciated it, which is to say where I am now.

Strong indication: the BK is being mated in c4.

Let's move on to the continuation of the course.

As you will see, and indeed as you would expect, there is only very big.

And I repeat, you don't have to be an expert to recognise beauty when you come across it..

When you explain these different types, it seems a bit artificial (even very artificial!) and the simple theoretical presentation makes you think about what life must have been like for flies in some English denominational orphanages....

The great Turnbull provided the material and the master explained it to us. Quite luminous presentation !

**the oral presentation is superior to the written explanation**. For the same reason, I will not go into it either, except for the simplest example which I will try to develop a little more..

Growing Men. Whites play and mate in 5 moves.

** We have already seen the Growing Men.

A piece cannot play a move shorter than its previous move..

This means that as soon as a piece has played a move of geometrical length n, all its subsequent moves must have at least this length..

** The length of a move is determined by measuring the distance between the centres of the start and finish squares..

A K therefore makes moves of length 1 (when it makes an orthogonal move) or 1.4 (root of 2, when it makes a diagonal move).

The Knights are not directly impacted by this rule, as all their movements have the same length (root of 5, i.e. about 2.24)..

** When we are interested in the moves played previously (retrograde analysis) we will apply the following principle :

All moves that cannot be shown to be prohibited are allowed.

In the case of Growing Men (it would be more precise to say "non-shrinking"), a K or a P will have the right to play a move of length 1, unless the contrary can be demonstrated.
