A few final words...
Well, first I would like to thank all the participants for their kindness in correspondance, and all the hours, hard work, and combativity that they have put in this tournament. Such tournaments demand a lot of energy, and I wouldn't be surprised if some lost a few pounds :-)
There was a high level of creativity exhibited, like in previous competitions. Some matrices and ideas are true gems, to say the least, and I was in awe before them. That said the combination of all the requirements was probably somewhat harder to work with than in the previous tournament. For example in the C and D categories, it was relatively static for a long time, until first Cornel broke a barrier, and then Arno came up with an unbelievable "magical" idea.
One thing that surprised me a little bit was that there were very few (and only in the low dimensions) matrices based on promotions, while in (all?!) previous help-stalemate tournaments, these proved quite strong. Probably the Lortap condition is responsible for this, as it may be harder to coordinate pieces.
This tournament was dominated - to say the least - by Arno. Many congratulations to him! Quite an incredible feast, he won all the categories, and with style! :-) And a surprising fact is that he is the only one to have actually passed all the requirements for the initial challenge...
I will let you now have a look at the matrices... there will certainly be several errors, please let me know if you find any. The total number of emails I received for this competition has been quite less than the previous one, "just" 282... :-)
Several of the low dimensions matrices could well be considered as good puzzles! Take for example the D2/3/9... the question would not include the number of moves for that one, just the total number of pieces.

Precise clockwork precision... Notice the "triple" check to start with :-) The bishop at h8 must be captured last, leading to a very long trip... the Lortap condition playing a vital role. |

How do the competitors come up with such ideas, beyond my wildest dreams to even imagine this :-) I cannot even start to explain, one must go through it and admire the precision with which each move is executed, and why one move is possible while another one not... |

Notice the brilliant idea, of having to capture the pawn at h7 first, liberating the rook at h8 and thus enabling the king to go and capture this knight at h2, before returning to capture the rook! Hard to do better "Lortap" than that... |

11.Ka4-a5 12.Ka5-a6 13.Ka6-a7 14.Ka7*b8 Absolutely brilliant idea... quite incredible. Look closely at all the elements. Starting with the fact that the king cannot take the rook as he would then be imprisoned. Then the two(!) black knights, how they interact perfectly, each move being unique, using the Lortap condition so well! And the idea of the queen at h1, permitting the final position... |

25.Ka4*a5 26.Ka5*b6 27.Kb6*c7 Very nice matrix! Again, the Lortap condition plays of course a vital role here. For example the bishop at h8, protecting the white king and not permitting the final position if not captured! Pretty final position also... |

Addendum
Computer generated solutions
Unbeknown to me, and to anyone else, François Labelle has been also participating "in the dark" for 2 months, using computer programs to find good (not perfect) solutions. He sent me his results, which are very interesting. I thank him for that.
First, here is the complete analysis up to 4 pieces:
B/3/12 (8 problems, 1 matrix)
B/4/18 (102 problems, ? matrices)
D/3/9 (8 problems, 1 matrix)
D/4/12 (8 problems, 1 matrix)
Thus we see that the participants
found the best for those, and the only possible matrices for the B/3, D/3 and
D/4. For the B/4, one interesting additional position is:

Another interesting position - puzzle
like - is one resembling the D, but here the goal is to have a solution in x
moves, but not in x+1! Interesting concept, maybe for a future tournament :-)

A more elaborated example from Cornel. Notice the similarity with one of the C1 entries... what one can do with just a switch of a knight :-) |
Now for the best in the main categories, he found a better matrix for the A1
category, but not for B1, C1 and D1. Nevertheless, the C1 is also most interesting,
and ends virtually at 2nd place.

Very nice and elegant... a kind of "perfectly positioned" bishop batteries formation. The final stalemate is quite elegant too. Interesting the series of 4 consecutive captures from moves 14 to 17... |
