A few final words...

As always, a big thank you to all the composers who participated, and also to those who followed it with interest. It was again a success thanks to great inspiration and dedication, leading to beautiful matrices and ideas.

It is a very tough challenge and takes a lot of energy from the competitors no doubt, but I believe - I hope - that it is worth the effort.

An interesting aspect of this particular tournament was the possibility of using three different stipulations. In the beginning, ser-h!= was a little bit tried out, until ser-h= definitely took over, for about a month. Then Arno came up with an extraordinary ser-h!= idea, with which he could take over most of the A2 table, a few of the B2 table, and a most beautiful A1 entry.

All the participants showed great ideas as you will soon find out. I truly wonder how they do that, as personally I am quite sure I would not be able to.

I will not comment the problems at all this time and leave you the pleasure of finding out how and why they work. It's really fascinating, and embedded with perfect logic.

All the A1 and B1 entries are very different from one another, which shows the level of creativity involved, and the possibilities of the theme (which are most probably far from exhausted).

I would greatly encourage you to closely study those (or eventually to try to solve them without looking at the solutions first, in order to better appreciate the different ideas), there are true gems there. As I believe chess composition is an art, each one of those could be seen as a beautifully constructed piece of art.

Congratulations to the 1st Places, Ralf in category A1 with an extraordinary problem, Arno with a no less beautiful matrix in category B1 (and A1), and who also succeeded an almost perfect score for the number of records, 13 out of 14! That is an enormous achievement.

Ján & Ivan came very close to Arno in Category B1, just one move (and piece) away! And also all the composers who succeeded to pass 100 in category A1, Ján & Ivan, Miodrag, and Cornel, it is no doubt a great achievement by itself.

The lower dimensions matrices shown by the A2 and B2 records are also most interesting and deserve special attention. Each one is a puzzle in itself, and could even be given as a challenge in task form for the very low dimensions ones.

If any of the participants wishes to comment on any of the problems, please feel free to send me those and I will add them.

Thanks again!

Arno: A splendid “logical” series-mover with a clear main plan that needs to be carefully prepared by multiple fore-plans. With a white TR or SI on g8 or h8 Black could play his ND to f8, the king to e8 and c6-c7 stalemates. Therefore one of the units on g3 or h4 needs to be captured. However, to achieve that the bND needs to help the bK by moving to g5. The bK can make this possible from e5 but when opening with f5 and NDg7-f6-g5 the white NDh8 pins the bND! Therefore, White needs first to capture it by 22.Kxh8 [Fore-plan No. 1]. Now the bND can be helped to g5 by 42.Ke5 43.f5 and 45.NEg5 [Fore-plan No. 2]. Next step seems to be 49.Kxh4 (SIh8)?! but it turns out that then the bND can never return to g7 and f8 as the bK is hindered to enter e5! Thus, the bK must first care that h8 is again occupied by a wND by playing 65.Kxh7 (NDh8)! [Fore-plan No. 3] and then capturing the wSI 85.Kxh4 without rebirth! [Fore-plan No. 4] Now the wNDh8 needs be captured with 105.Kxh8 [Fore-plan No. 5] so that after the capturing of the wTRg3 by 123.Kxg3 (TRg8) [Fore-plan No. 6] the way to e5 is free and the bND can be led back to g7 and f8 by 126.Ke5 and 129.NDf8 [Fore-plan No. 7]. And finally the main plan... The absolute best achievement in this tournament and a clear winner not only in quantity (number of moves) but also in quality!

Ivan: I must say that this entry is in my opinion the best among the other entries. We can see a splendid matrix with great synergy of black King and bishop.

Arno: This was a happy connection of two relatively simple ideas: first, the configuration of the wK with the black marines pieces that are thus “frozen” to their places until the very last move as any move of them checks the wK, and second, the fact that in a series-help-auto-stalemate just all the white units need to be captured, and in CIRCE this leads to long series if each unit needs to be captured twice. The current matrix has an interesting feature by allowing the bK the first 80 moves just to move at the very border, and then after 80. Rxb2 it can finally enter the center. It was not easy to reach 143 moves but more should be possible – who shows me how?

Ivan: Great Arno’s idea finishes with surprising final stalemate with four white stones.

Arno: Also a wonderful “logical” series-mover – here the hidden main plan is to play the wNDc1 to c8 and for that the bK needs to be very careful when choosing the next capture... This is very hard to solve as often it becomes only visible quite late when you grabbed a piece too early. It is a miracle that all this works without any dual!

Ralf: 1. Kxa5? but white must first capture pawn f6. Quite complex.

Ivan: Many king returns with all known mechanism using nerëide in the Southeast corner. Comparing first places the king’s walks are rather short.

Arno: Lucky for the first places that Miodrag only started so late with his ideas. Here he even does not use two of the fairy pieces (as the wNDh8 only gives one move) and comes to a surprising 118 moves. Relatively easy 7 moves can be added by adding two units but even (much?) more should be possible...

Ivan: Final stalemate with five (!) white stones. Black in interesting way releases the nerëide. Colossal Miodrag’s tour in only two days.

Arno: I had a lot of good luck that this wonderful matrix seemingly does not give two moves more! It is very surprising that the authors could achieve such precision in move order in the Southeast corner.

Ivan: Thick and terrible position only to lengthen the solution. Knight a2 does play no role (except two moves more). Hunt the maximum length sometimes doesn’t bring good entries.

Ralf: The main matrix (white king between sirene and triton) of the tourney and the stipulation ser-h!= is the clue for the records in the lower dimensions.

Ivan: This matrix (without white knight and with king’s pendulum) was probably found by other competitors. But with white knight on a6 black king must walk around.
