New Records

I am very glad that the participants continued to look for improvements even after the tournament ended. And successfully so! Several matrices were improved, and also new ones discovered.

They also looked beyond the limitations of the tournament, as for example matrices for the A2 and B2 categories, with more than 10 pieces in total. They are shown here as A2 and B2s.

A few final words...

Well, another successful series tournament, with some truly incredible matrices composed.

This was a special one for several reasons. One of them is that it was the last one I will organize, at least for a very long time. I would like to sincerely thank all the participants, from the very first tournament to this one. A special thanks goes to the participants of this tournament, many of whom participated in most, if not all of them!

It was a great experience for me, and I hope for many other composers. As organizer one has a quite different view than as a participant, and it is a very nice and enjoyable one.

I could talk a long time about all the benefits that organizing those brought to me personally, but I will name just a few.

First of course the great challenges that it offers to composers. I like tough challenges myself, and giving the opportunity to others to "surpass themselves" is a reward in itself. Second, all the composers I met, and friends I made as a result is something I will always treasure. A few I did know previously, but most not. Third, it was simply a lot of fun. And finally, well, all the beautiful compositions that those tournaments produced is a testimony that this kind of tournament has a part to play in the composition world, and maybe should be developed further.

Now back to this tournament, the conditions were somewhat atypical. This resulted in a fairly extensive "study" of this genre, with matrices that wildly surpassed my expectations for originality.

There is also the "famous" E category, that was added in the beginning. Adding the Kings to the Immun condition was a little gamble. Will it be popular, or not. It started quite slowly, before gaining momentum after a few weeks, to become one of the most popular category. It gave some beautiful matrices as you will soon see.

The level of creativity was extremely high, from all the composers. Practically no two compositions were even closely related. With some exceptions evidently.

I would encourage all solvers (and others) to try and solve at least a few of them (maybe the low dimensions ones first). I believe some are really tough, but enjoyable to solve.

As in the last couple of tournaments, there were very few matrices with promotions. This is probably due to the conditions, and also the rule that there must be a non-Pawn black piece on board, which must make at least one move. There were just two of those. But both really beautiful, one by Ivan, and one by Ralf.

Congratulations to all the prize winners. A special word must be said about Ralf, he composed some true gems in the high dimensions (and low ones too), and fully deserves the first prizes. Arno too came up very strongly at the end, with some great matrices, and a quite unbelievable A1.

I decided to award many special prizes to matrices that did not make it to any table, but that I found really elegant.

I added short comments to many of the problems, but not all, where I felt appropriate. No comments to a problem doesn't tell anything about its elegancy of course.

Please feel free to send me your comments about any of the problems if you wish, and I will add them.

As in the previous tournaments, I surely made at least a few mistakes in this result page, although I tried my best not to. If you find any, please tell me so and I will correct it as soon as possible.

Thanks again!

This is quite an incredible achievement. Fully using all the pieces available. The Bishop shields the King in two very long tours, but then the intended final position is also quite something, with the two black pieces pinned!

Very pretty matrix, and one of the few with three black pieces other than pawns. To block the Knight it is necessary to capture the Pawn h6. Notice the elegant switchback of the black Bishop.

Arno sent this matrix after the tournament, but as during the tournament he sent a ser-h=62, it doesn't change the order, and it is thus ok to replace it here.

Elegant matrix. Notice how the King loses a move at c1/c2, which is no longer possible after the first capture. Also the h4 pawn cannot be captured before the Bishop, and once captured, the King must do another tour to return to g2.

Another gem from Ralf, and quite complex. The idea being that in the final position, in order for it to be a stalemate, the Knight at b4 must be immuned, and thus the Knight at c1 must first be moved to g1.

A Masterpiece. Really an incredible feast, the pawn d6 threatening to capture the bishop e5 is the key. Notice the final position, where the King cannot capture the Bishop not because there is a piece on f1, but because of auto-check.

Very pretty matrix. The idea being to capture the pawn at e6 in order to be able to pass the Bishop b5. But the only piece which can capture the Knight g5 is the Bishop, and the white King must be immune to checks beforehand.

This was a kind of an optimized base matrix. Quite pretty. Notice the doubling of the RexInclusiv theme.

Well, a very nice and special version of the A1 without promoted pieces! Now the only move giving the dual is the very last move, and a promotion. Arno provides the following information as it could be viewed correct according to the Codex of Chess composition. Quote of Article 13, Paragraph (2):

"Help-play compositions are unsound also if they are dualized, except that in the final move a promotion into different pieces having partially the same power (for example queen/rook or queen/bishop) may be tolerated."
