Note by Alkinoos :
Mr Sklavounos has contributed to the posts of this blog with interesting topics. I happen to know that he is a polyglot (he speaks Greek, English, French, German, Italian) and he has received two literature awards (one in a science fiction novel contest of the Greek General Secretariat for the New Generation, in 1987).

The Sword of Damocles

First, some historical details for the expression of the title.

The city of Syracuse, Sicily, was ruled in ancient times by the tyrant Dionyssios. Among his courtiers there was a flatterer named Damocles, who envied the wealth and the glory of his master.

In a circumstance, Dionyssios asked Damocles if he would like to try sit in the throne. Damocles gladly accepted the invitation and started to enjoy the comforts of his lord. Examining curiously everything around, Damocles noted that above his head a sword was hanging, restrained only by a few horse hairs. Naturally, the hair might be cut at any time...
Dionyssios had placed the sword above the throne, to remind him to take the right decisions, since he could die at any moment and he could not correct any misjudgments.
Damocles was terrified and immediately left the seat of the lord, which seemed not enviable any more.
The phrase [Sword of Damocles] specifies the deadly danger threatening us, and has passed from Greek language to other languages (for example, in French : L' epee de Damocles).

This title was given, in 1865, to the problem we present today. Since many dangers are threatening us, the problem has two solutions.
(In the era of this problem the element of economy in pieces was not very strict).

	(Problem 381) "L' epee de Damocles ", M. Schoumoff de Saint-Petersbourg, Journal des Echecs, 1865-6, (Vol.2, p.238), by Paul Journoud, Paris Mate in 3 moves. #3 (10 + 1)
[8/8/2S5/PPKBBRPP/2S5/8/8/6k1]

The solution follows ...

---

A.
Key : 1.Rf3!
1...Kg2 2.Se3+ Kg1/Kh1 3.Rf1#
1...Kh1 2.Se3 Kg1 3.Rf1#

B.
Key : 1.Bh1! Kxh1 2.Se3 Kg1 3.Rf1#

It is quite obvious that the lonely King (theme : Rex solus) is condemned from the beginning.

The Esthetic Beauty is measured by computer

An article was published today in Chessbase about the doctoral thesis of Dr Mohammed Azlan Mohamed Iqbal, who is 31 years old and works in Malaysia.

The doctoral thesis [A discrete computational aesthetics model for a zero-sum perfect information game] examines the question if the beauty of the chess combinations is measurable by computers.

To people, some moves seem to be much prettier than others. Some combinations seem to be marvelous, while others seem indifferent. The computers play the chess game at the level of Grand Master and make combinations of all kinds, without giving weight or preference to beautiful moves. Could we teach the machines to “count” the esthetic beauty of their moves?

The researcher has studied, using special software for measuring esthetics [CHESTHETICA], many games and particularly three-mover problems, while at the same time, using specific questionnaires, has gathered the opinions of many persons whether some positions and combinations and solutions seemed to be beautiful.

By comparing the measuring-software results and the opinion-questionnaire results, an impressive conclusion arose, that the esthetics (at least for the limited researched area) is measurable!

Dr Mohammed Azlan Mohamed Iqbal hopes that his pioneering work and the software he developed could help the Judges in contests of chess compositions, or the persons giving Beauty prizes to chess games.

Best Study for 2005

Today we will see the study which was selected as best for the year 2005 from the PCCC, (Permanent Commission of Fide for Chess Composition).

[Study of the Year 2005] is a composition by Yuri Bazlov (who received this distinction the next year also).

The study has got some difficulty.
If the pawns and the white Knight are captured, no black piece must be lost.
If the Knights are captured, there is theoretical draw (K+B+P vs K+P) in some places.

The position should be very interesting for the Over-The-Board players.

Study of the year 2005.

	(Problem 380) Yuri Bazlov, 5th Prize, Tourney for John Nunn's 50th birthday, 2005, White plays and draws. = (3 + 4)
[8/1k3s1K/6S1/6b1/6p1/8/6P1/8]

The solution follows...

---

Key : 1.Sh8!
(The alternative is [1.Kg7? Sd6 2.Se5 g3] but Black can secure his pawn on g3 and gradually improve the position of his pieces. Of course, he must avoid the exchange of knights, which leads to a positional draw provided White’s king can reach f1. Although the win is not easy, it can be accomplished in the end; for example, [3.Kg6 Bd8!] stopping the white king reaching e6, after which it is very hard for Black to displace the centralized white pieces).

1...Se5
(the only winning chance is to prevent White’s king moving immediately to g6. After [1...Sxh8 2.Kxh8 Kc6 3.Kg7 Kd5 4.Kg6 Be3] Black cannot move his bishop to f4 or h4 without losing his pawn, so he loses another tempo later when White attacks the g3-pawn with his king [5.Kf5 g3 6.Kg4 Bf2 7.Kf3 Kd4 8.Ke2!]. The king reaches f1, with a standard positional draw).

2.Sf7!
(Already one piece down, White offers a second one!)

2...Sxf7
3.Kg6! Ne5+!
(The best try is to sacrifice the bishop, as [3...Kc6 4.Kxf7 Kd5 5.Kg6] draws as in the note to Black’s first move).

4.Kf5!
(Declining the offer. [4.Kxg5?] loses after [4...Kc6! 5.Kf4 Kd6!] gaining the opposition [6.Ke4 (6.Kf5 Kd5 wins) Ke6 7.Kf4 Kf6 8.g3 Ke6 9.Kg5 Kd5 10.Kf5 Kd4 11.Kf4 Kd3!] and the g3-pawn falls).

4...Sf7
(Amazing but true; Black cannot win despite being two clear minor pieces up. [4...Sf3 5.Kxg4] and [4...Bf6 5.Kxf6 Sf3 6.Kf5 Sh2 7.Kf4] are both clear draws).

5.Kg6 Se5+
6.Kf5! Draw.
