10th International Solving Contest

The 10th International Solving Contest, for 2014, is announced

Saturday, December 28, 2013

2013 is almost past

The year 2013 has given me joy with international distinctions, as similarly happened to various Greek composers and I am happy for them when they achieve better awards than me!
There were also some cooperations, not yet published, which gave me great satisfaction with their beautiful results.

This same year I was disappointed when I tried to organize regular gatherings for friends of chess compositions in a place, for exchanging news and ideas.
There was no significant interest or maybe there was not enough publicity for this matter.
If someone is learning about this just now and is interested, he can contact me.

In the next year 2014 I suppose that things will become better.
There is a new move by Nikos Mendrinos, The Cup of Greece, solving contests happening simultaneously in many cities of Greece. I hope that this will give the needed push to increase of the number of the Chess Composition friends.

Let 2014 be a good year for everyone!

A prized series composition

In "series" compositions, one side makes moves alone, alters the position in some fashion, and when its moves are completed, then the other side mates or stalemates, accordingly with the stipulation.

Today we will see a ser-s=198, that is a series inverse stalemate in 198 moves. The white plays 198 moves alone and in the last one the black plays and is forced to stalemate the wK. This composition was awarded with 1st prize in a tourney and is a world record in its category. (See the presentation with a Sherlock-Holmes-like story in page 5 of the document :
Four black Pawns have been promoted to bQ, bR, bR, bR. The wK has difficulty in moving around the chessboard with the assistance of the wB, but the wK is obstructive and the wB makes large rounds.
During the writing of the solution, we omit the moves which are easily deducted.

The composer, Arno Tüngler, is very succesful with very long compositions.

Greek selfmate from 1946

Mr Panagis Sklabounos discovered and sent to me a selfmate by Ioannis V. Koutalidis, which was published in the Greek magazine "Helios" in 28 Aug. 1946.
As I have mentioned elsewere, mr I. Koutalidis, editor of the chess column of the magazine, motivated and decidedly cultivated the talent of young composers (Vyron Zappas, Nikos Siotis, Dimitris Kapralos) of that time

In a selfmate, White plays first and forces Black (who is resisting) to give mate.

Three studies by Kyriakos Fragoulis

Kyriakos Fragoulis (1935 - 1997), from Leykada island in Greece, became well known in composing circles with his studies. There were other Greeks also creating chess problems of various types, but Kyriakos Fragoulis was composing exclusively studies.

Study is a position with stipulation "White plays and wins" or "White plays and draws" without specifying in how many moves we must achieve it. The study is like an endgame, but it is a composition, it is not coming from a game.

The players of over the board chess are solving studies as an exercice.

These studies were sent to me by Panagiotis Konidaris from Meganissi (an island near Leykada), who had actually met Kyriakos Fragoulis. Panagiotis says that he found them in some old and turned yellow pieces of paper (thanks Panagiotis!), and they are unpublished, as far as I know.
Their solutions are visible only if you select the text between the square brackets [...].

Nikos Pergialis, an evergreen composer

As we have already mentioned, Nikos Pergialis is a special kind of composer.

He is composer and singer of rebetiko songs, the last rebetis of our time. Here you can listen him singing a song written by the great Markos Vamvakaris :

He is also a composer of chess problems, favoring beautiful and frugal positions.

Today we will see two direct-mate two-movers and two helpmates, a three-mover and a four-mover.

Nikos Pergialis, Greece
5R2/4p1p1/8/8/4pP1R/4Pk2/5P2/5K2 (6 + 4)

Two mates by en passant capture.
Two changed mates, between set play and post-key play.
From 8 up to 12 pieces, it is a Meredith.

The composer says:
I am not going to reach old and new chessplayers and all the problem-makers
because it happened to me to lose all my prolific years.

Theme Gamage (White can unpin a black piece, because Black has just interfered with it).
Black correction (Black plays 1...Rd5-b5 to correct the inherent error of the move 1...Bh3-d7).
Move Pelle (the pinned Rd5 moves, remaining pinned).
It is Imperial, having no pawns.
From 8 up to 12 pieces, it is a Meredith.

The pieces make 18 moves, all different.
Three ideal mates are formed (all the pieces take part), all similar.
Chameleon mates (bK is mated on squares of different colour).
Up to 4 pieces, it is a Weningsteiner.

Model mates (bK and every flight are observed or blocked by only one piece).
Theme Indian.
The White battery is direct (threatening the bK), or indirect (observing a flight).
From 8 up to 12 pieces, it is a Meredith.

The composers says:
Let us take a walk hand in hand, my foolish Black King,
and if I am preparing your funeral, blame the anomaly.

Mate with two Knights on the edge of the chessboard

There is a beautiful problem by the French poet and novelist Alfred deMusset since 1849, which shows a mate with two Knights on the edge of the chessboard. In order to achieve such a mate, one must have another black piece on board, which may disappear in the final picture of mate, or a pawn not too advanced (see Troitsky line).

#3, Mate in three moves

1.Rd7! [2.Sf6#] Sxd7
2.Sc6 Sf6+
final picture of mate

I like this problem and I have composed, for a recent composition tourney, a helpmate two-mover twin.
On the first of the twins, White manages easily to force a mate on the cooperating Black with two Knights on the edge of the chessboard, (making two simple moves and two captures).
But on the second problem a black Rook is placed on board and inhibits the mate of the first twin! White, more difficult now (with four captures, pins, unpinnings and removals of guards), manages again to achieve the mate with two knights, but in another edge of the chessboard!
For a two-mover, I consider it nice, (and it is irrelevant that the judge saw the two solutions unsimilar and gave no distinction). Of course, the two fairy conditions were very helpful TakeAndMake (the capturing piece makes one move with the way of the captured piece. Example: if a Rook captures a Knight, the Rook must make one more step as Knight) and Anti-TakeAndMake (the captured piece is not removed from the game but it makes one move without capturing anything on the arrival square.
Final result, with the two fairy conditions combined, is a situation described recently as Bulgarian billiard.
Example: (1) if a Rook captures a Knight, the Rook must make one more step as Knight, and the Knight stays on the board and makes a move itself as a Knight. (2) if a Knight captures a Bishop, the Knight must make one move as Bishop, and the Bishop stays on the board and makes a move itself).

A simple nine-mover

At this time of the year, those composers wanting to participate to the Tourneys of the World Congress of Chess Composition, are over their chessboards trying for their best. I am one of them and I am sorry if the posts in this blog are not frequent.
New tourneys are continuously announced, some of them open for composers from all over the world (not only for the participants of the congress).
Sometimes we go astray, not following the strict guidelines of the judges, and we make other compositions, just for fun.
Today's nine-mover could be sent to one of the Batumi tourneys if it was difficult and two-mover! But it is not, so I present it to you as an exercise. If you write a comment with the solution, please include the specific one of the tourneys I was implying.
