Solving Contest, 2008-04-19, ESSNA Pagrati

Left to right : Papastavropoulos, Anemodouras, Garoufalidis, Ilandzis, Mendrinos, Konidaris.


The 5th Solving Contest of E.S.S.N.A. (Union of Chess Clubs in Prefecture of Attica), contest surnamed "Byron Zappas", was successfully held in Chess Club of Pagrati in Saturday, April 19.
Eighteen solvers participated, having 2h 15m available time to solve 6 problems (1 two-mover, 1 three-mover, 1 four-mover, 1 study, 1 helpmate and 1 selfmate). The contest was dedicated to the top Greek composer of chess problems Byron Zappas, who died this year. All the compositions of the contest were created by Greek problemists.

The following persons gathered the most points :
1. Nikos Mendrinos (25 grades in 30) champion of Attica,
2. Andreas Papastavropoulos (20),
3. Panagiotis Konidaris (19),
4. Leocratis Anemodouras (15),
5. John Garoufalidis (15),
6. Spyros Ilandzis (14).

Best team proved to be "Zinon Glyfadas". No prize for category "young under 20 years old" was given.

Siaperas Triantafyllos

Siaperas Triantafyllos, (01 August 1931 - 25 February 1994), all his life was promoting chess matters, as player of games, as composer of problems, as man of the press, as book writer, and was very successful in all his endeavors.
He was a decent person, with excellent memory and erudition, and when he was teaching, his politeness was evident.

He held the Greek record for blindfold chess with six chessboards.

Siaperas Triantafyllos up to his twenties has lived in Yugoslavia, where he was busy composing chess problems and teaching composition to others. Milan Vuksevich, International Grand Master in composition, in every opportunity in his books and articles was thanking his tutors. In “Chess by Milan” (1981) Vuksevich writes: “Great teachers never die – they are the only life form which reincarnates! ... Trandaphilos Siaperas, friend of the family, born in 1933, was the problem editor of Belgrade ‘Sah’ from 1946 to 1951. He had a gift to hide his superiority while giving you the knowledge. He played ferocious attacks and created beautiful Bristols and reciprocal effects”.

Siaperas moved to Greece in 1952. For almost fifteen years he was playing chess in Thessaloniki (=Salonica), at club “Enossi Skakiston Thessalonikis” (=Union of Chess players in Salonica). He lost no game from the 110 that he played in local championships and cup tourneys, where he was every time the first winner.
In 1956 he became for the first time chess champion of Greece. He became national Master. He took part, playing on first chessboard of the Greek National Team, in the 12th Olympiad at Moscow (U.S.S.R.).
In August 1967 he published his book, (translated title: “Chess, Complete development of theory and its practical application, Vol. I”, 356 pages), first chess book of such a size that was written in Greek language. It was addressed to amateurs and to players of categories C, B, or A (higher), with systematic development of all the phases of the game (opening – middlegame – endgame). The book, with very many subjects and methodical presentation, functioned as a method without a teacher for at least two generations of Greek chess players.
From May 1968 to July 1969 he was chief editor of the monthly chess review “O Skakistis” (=The chess player), (issues #6 to #19).

He was the first Greek to become International Master (IM), taking eighth place at the international tourney “Acropolis 1968” (equal result with Lazaros Vyzantiadis). In preliminary games for selection of Greek national team he was first winner, but the coach of the team decided that Siaperas will play on second chessboard in 18th Olympiad at Lugano (Helvetia). Siaperas was very well prepared theoretically and he played a “positionel” game (strategic game of positions). Here is one of his games (06/11/1968) at Lugano:

White : Siaperas Triantafyllos (GRE) – Black : Heyns Anthony (RSA)
1 e4 e6 2 d4 d5 3 Sd2 Sf6 4 e5 Sfd7 5 Bd3 c5
6 c3 Sc6 7 Se2 Qb6 8 Sf3 cxd4 9 cxd4 f6 10 exf6 Sxf6
11 0-0 Bd6 12 Sc3 0-0 13 Be3 Bd7 14 Sa4 Qd8 15 Rc1 e5
16 Rxc6

A rook is exchanged for a knight and a pawn and the opening position.
16...Bxc6 17 dxe5 Qe8 18 exf6 Bxa4 19 b3 Bd7 20 fxg7 Kxg7
21 Qa1+ Kg8 22 Bh6 Rf7 23 Sg5 Be5 24 Qb1 Rf6 25 Bxh7+ Kh8
26 Re1 Rxh6 27 Rxe5 Qh5

Black threats Rxh7, also Qxh2+, but there is no time.
28 Re8+ ( 1-0 )
The second rook is sacrificed, on a square where three black pieces can take it, and the diagonal a1-h8 has been opened for the white queen, which will start with Qb2+ and will end with mate (i.e. 28...Kg7 29 Qb2+ Rf6 30 Re7+ and white wins).

In 1969 he knew a triumph in a great international tourney at Zagreb (Yugoslavia) taking the fourth place, with only one defeat in 15 games with strong opponents, ensuring his International Master title. In Greek championship Siaperas took third place. He was the winner in preliminary games for Zonal-3 (preliminaries for World championship) but in the finish of Zonal-3 he was 16th. In inter-group games for national category A, he played on first chessboard with “Enossi Skakiston Thessalonikis”.
In 1970 he played on first chessboard of the National team of Greece at the 19th Olympiad at Siegen (Germany).
In August 1970 was first published the Ellinika Skakistika Chronika (=Greek chess chronicles), official monthly magazine of the Elliniki Skakistiki Omospondia (=Greek Chess Society), (E.S.O.). Responsible of material and Editor of publication : Triantafyllos Siaperas. It was a large size magazine with impressively good appearance and extremely interesting content for OTB chess and chess compositions, being highest in quality among Greek chess magazines. All the covers pictured the same smothered mate (Mat à l’Étouffée) changing only colours, up the issue #38-41 September - December 1973.

On 30/04/1971 Siaperas held place #214 (his highest) in world ladder with ELO 2418. In 1971 played on first chessboard for Greek team at the international match Pula (Croatia).
On 30/04/1972 Siaperas held place #225 in world ladder with ELO 2427 (his highest).

In 1972 became for second time Greek chess champion. He became International Judge. He played on first chessboard for Greek team at the 4th Balkaniad in Sofia (Bulgaria). He played on first chessboard for the Greek team at the match with New Zealand in Athens. He played on first chessboard for the Greek National Team at the 20th Olympiad at Skopje (Yugoslavia).
In 1973 he played on first chessboard for the Greek National Team in a match with a Bulgarian team, and then in the fifth Balkaniad at Braşov (Romania).
In January 1977, ten years after the first volume, he published his book (translated title: “Chess, Theory and Practice, Vol. II”, 356 pages). It covered middlegame with two parts : (A) Dynamic play (play with tactical combinations) and (B) Positional Play (strategic play).
In 15/11/1982 is published the first issue of the fortnightly chess review “To Mat” (=the mate) with publisher Mr. Hatziotis Costas and Chief editor Mr. Triantafyllos Siaperas. The cooperation lasted until 1984.
In 1985 Siaperas organized the first (in Greece) live solving contest at Athens Hilton hotel with great success.
Mr. Siaperas was an excellent composer. He created high quality problems and studies. From the pages of the magazines he published and of the newspapers he worked with, he always tried to promote chess compositions and to give descriptions and examples for the various themes of the problems. The published problems of Greek and foreign composers, usually were included in running solving contests.

In the next diagram we see a prized problem of Triantafyllos Siaperas, in which the black, trying to avoid mate, six times self-blocks the flights of the king.



(Problem 120)
Triantafyllos Siaperas
First Prize ”Sah“, 1949,
White plays and mates in 2 moves
#2 (9+6)
[2R4B/1S1B4/8/4p3/Spr5/1P1kq3/K1s2Q2/4R3]

Try: {1.Bf5+? Re4!}
Try: {1.Qxe3+? Sxe3!}
Try: {1.Rd1+? Qd2!}
Try: {1.Rxe3+? Sxe3!}
Try: {1.Rxc4? Qxf2!}

1...Sd4 2.Rxe3#
1...Re4 2.Bb5#
1...Qe4 2.Rd1#
1...e4 2.Sb2#

After Siaperas's death and honoring his memory, the Skakistikos Omilos Ano Liosion (=Chess club in Ano Liosia) was surnamed Triantafyllos Siaperas, and various other clubs organize chess tourneys.


=====
Allow me, (fourteen years after his passing) to reveal a private conversation I had with him, in order to describe the wonderful mind of Triantafyllos Siaperas.
I had organized a problem solving contest (Patras, 05/02/1984) and he called me (long distance) to learn what had happened in order to write a comment in his newspaper chess column. He said (always politely):
«Will you please tell me the positions of the problems?»
«Should I use algebraic or Forsythe notation?» I asked naively.
«You may use whatever you prefer», he said.
«2 capital-K 4 capital-Q slash 8 slash 2 capital-S 5 slash 1 small-k 6...» I started to say.
He interrupted.
«Ah! The two-mover of Kossolapov from Novosty 1963. Nice selection! Please tell me the next.»
I was speechless. Twenty four years have passed and still I cannot believe it!

Triantafyllos Siaperas was really great.

1983-05-29, solving contest, Athens

Athens, Chess Problem Solving Contest 29/05/1983
In the pages of the chess magazine “To Mat”, (15/04/1983, issue 11, p. 260), its editor Mr. Siaperas Triantafyllos published a proclamation for an “OPEN” Live Contest for Chess Problem Solving. This Live Contest was the first to be held in Greece, aiming to bring together solvers and composers and to broaden the circle of chess players who tackle problem solving. The conditions:
1. All friends of chess have the right to participate.
2. Date/Time : Sunday 29/05/1983, 10:00.
3. Place : Athens Hilton Hotel, Ambrosia room.
4. Problems to solve : Orthodox 1 two-mover, 2 three-movers, 1 four-mover.
5. Respective grades : 2, 3, 3, 4 for each correct solution.
6. Additional criterion is time : Faster solver wins.
7. Max duration : 3 hours.

In chess magazine “To Mat”, (06/1983, issue 14, p. 315), we read that this pioneering, for Greece, happening was successful because many composers offered their help, among others Siotis N., Zappas B., Martoudis A., Dampassis N. and Fougiaxis Harry.
Twenty solvers participated in the contest, some of them known strong players.

The problems of this solving contest were the following:



(Problem 129)
White plays and mates in 2 moves
#2 (12+10)
[8/3s4/1P1B4/1P1p4/1QBk1p1p/pP1P1RbR/P1K3p1/1s3bS1]



(Problem 130)
White plays and mates in 3 moves
#3 (3+3)
[8/8/6pb/7k/3P4/2Q4K/8/8]



(Problem 131)
Walter Gleave
1st Prize, Cricket and Football Field, 1897
White plays and mates in 3 moves
#3 (5+3)
[4Q3/8/5K2/3k4/3P4/3p3P/3p4/3S4]



(Problem 132)
Erich Zepler
2nd Prize, Dresdener Anzeiger, 1926
White plays and mates in 4 moves
#4 (4+7)
[8/K7/8/8/1p3B1k/2p2Brr/s3pQ2/8]


1. First winner was the chess master Dimitriadis Costas of club S. O. Patron, who had solved correctly all the problems in the outstanding time of 36 minutes!
2-3. Second and third place : The known chess masters Pountzas Chrysanthos of club S. O. Patron and Pantavos Manolis of club S. O. Peristeriou.
4. Fourth place : Hararis Dimitris of club Fysiolatrikos Patron.
5. Fifth place : Chess master Delithanassis D. of club S. O. Xanthis.
6. Sixth place : Manolas Emmanuel of club S. O. Patron.

Mr. Siaperas commented: The four persons who traveled from Patras to Athens specifically for the Live contest, took four of the first six places, (1 - 2 - 4 - 6).

(The referenced persons probably belong to other chess clubs today).



The solutions of the problems of this solving contest:

Problem 129 : Mate in 2
There are many ready mates, (that is for several moves of the black, the white answers with mate). Should we try a waiting move?
Try: {1.b7? Bh2!}

Or should we attack instantly, in order to achieve mate?
Tries: {1.Bxd5+ Kxd5!}, {1.Qc3+? Sxc3!}, {1.Qc5+? Sxc5!}, {1.Se2+? Bxe2!}.
The key may put the queen in a dangerous area, but the black is in zugzwang, that is, whichever the black defense is, the mate in the next move is inevitable.
Key: 1.Qe1!
1...Sc3 / Sd2 2.Qxc3# / Qa1#
1...Bxd3+ / Be2 2.Rxd3# / Sxe2#
1...Bxe1 / Bh2 2.Rxf4# / Qf2#
1...dxc4 2.Qe4#
1...Sd7~ 2.Q(x)e5#
(To symbol Q(x)e5 means that the queen goes to e5, possibly taking a piece there).

Problem 130 : Mate in 3
Here, the queen must come closer, but we must discover the way
Tries: {1.Qa5+? / Qc5+? / Qg3? g5!}, {1.Qf3+? Kg5!}.
Key: 1.Qe1! [2 Qh4#]
1...Bg5 2.Qe5 Kh6 3.Qh8#
(If 1...Kg5 / g5 2.Qe5# / Qe8# the mate occurs in only two moves. This is a weakness of the problem. Since it is a three-mover, we would prefer today all the variations to have three moves).

Problem 131 : Mate in 3
Tries: {1.Qa4? / Se3+? / Sb2? Kd6!}, {1.Qd7+? Kc4!}, {1.Qe6+? Kxd4!}.
Key: 1.Ke7!
If 1...Kc4 2.Qa4+ Kd5 3.Sc3#
If 1...Kxd4 2.Kd6 Kc4 3.Qa4#
If 1...Ke4 2.Qd7 Kf4 / Kf3 3.Qg4#

Problem 132 : Mate in 4
Tries: {1.Bc1? Sxc1!}, {1.Bd2? cxd2!}, {1.Bh6? Rh1!}, {1.Bg5+? Kxg5!}, {1.Bc7? / Be5? Kg5!}, {1.Qxg3+? Rxg3!}, {1.Qb6? / Qc5? / Qd4? / Qe3? Rg7+!}, {1.Ka6 b3! (and black will continue with 2...Sb4+)}
Key: 1.Kb6! [2.Qd4 [3.Qh8#]]
1...e1=Q 2.Qxe1 ~ 3.Qe7+ Rg5 4.Qxg5#
1...c2 2.Bd2
___2...Rh1 3.Qd4+ Kh3 4.Qh8#
___2...~ 3.Qd4+ Rg4 4.Qxg4#
1...Sc1 2.Bxc1 Rh2 3.Qxh2+ Rh3 4.Qf4#
1...b4 2.Qd4
___2...Rg6+ 3.Bd6+ Kg5 4.Qf4# (To achieve this mate, the white should bring the king on the row-6, in order to lure the black rook on square g6. The black rook goes there to give check but later it blocks a flight of its king).
___2...Rxf3 3.Qf6+ Kh5 / Kg4 4.Qg5#
This was a tough problem, with many tries and many variations.

Line Openings (2)

We say that a linear piece A makes a critical move, when it moves beyond a critical square, where a second piece B will arrive and, by its presence, it will hinder the influence of the linear piece A.
If piece A has passed over the critical square in order to avoid the hindrance of its influence by some piece B, we say that piece A made an anticritical move.


Doubling of pieces happens when we put two pieces on the same row (or column or diagonal).
Theme Turton doubling : A linear piece A moves beyond a critical square, permitting to a like-coloured and stronger piece B to move onto the critical square. Later piece B moves on the same line to the opposite direction, being supported by piece A.
Brunner-Turton doubling : The pieces A and B are equal in value.
Loyd-Turton doubling : Piece A is stronger than piece B.
Zepler-Turton doubling : Initially the piece A moves. Then piece B steps on the critical square. Then piece A moves again, being supported by piece B.
Bicoloured Turton : The pieces A and B have different colours.


The line opening in problem-19 is not a “Bristol”, because the two pieces which move on the same line, are moving in opposite directions, that means it is a Turton doubling..


(Problem 19)
Sam Loyd
”Cincinnati Dispatch”, 1858
White plays and mates in 3 moves
#3 (4+7)
[2s5/6p1/8/5p2/8/7S/3pp1B1/KQ1bk3]

Key: 1.Ba8!
The bishop goes up the diagonal h1-a8 (over square b7), in order to make space for the white Qb1, that will move on square b7 and will move down the diagonal and will give mate from square h1).
1...g5 2.Qb7 ~ (the symbol ~ means any move, black plays anything) 3.Qh1#
1...f4 2.Qg6 ~ 3.Qg1#
1...Kf1 2.Qxf5+ Ke1 3.Qf2#
1...Sd6 (does not allow 2.Qxf5 and 2.Qb7) 2.Qb6 ~ 3.Qg1#
In the final picture of mate, Ba8 does not take part, so it is a parasitic piece.


Theme Cheney-Loyd, is the case when the white piece A makes a critical move and the white piece B goes to the critical square and interferes.
Black Cheney-Loyd is the case when the black piece A makes a critical move and the black piece B goes to the critical square and interferes.
Bicoloured Cheney-Loyd is like Cheney-Loyd, and the pieces A and B have different colours.


In the next problem we see the parasitic piece moving to open a line for a piece, which is not giving mate but it is closing flights of the black king, and that means it is a Cheney-Loyd interference.


(Problem 20)
J. W. Abbot
"Baltimore News", 1890
White plays and mates in 3 moves
#3 (5+2)
[3K4/8/3k4/8/3p4/P2P4/8/2R1R3]

Key: 1.Rc8! Kd5 2.Kc7 Kc5 3.Re5#

In this problem the pawn a3 is a revealer : It is a fact that in a problem only the absolutely necessary pieces are included. Seeing the pawn at square a3, we understand that, during the solution the black king will move towards a3.
Parasitic piece here is Rc1. The rook Rc1 must not leave the c-file, in order to force Kd6 to move to square d5. Then the black Kd5 must not return to d6, but must be forced to go to c5 (then, where should the rook of c-file stand ?). And, finally, the mate must occur on the square c5, because no more moves remain.


On the next prized problem-21 the composer Triantafyllos Siaperas presents two themes, Bristol line-clearance and Turton doubling, with a very nice way.

(Problem 21)
Triantafyllos Siaperas,
First Prize, ”S.A.H.”, 1948
White plays and mates in 3 moves
#3 (7+7)
[SK6/8/PB1p4/1k1bR2Q/1p6/1p6/qp1P4/8]

Key: 1.Re1! [2.Qxd5+ [3.Qc4#]]

If 1...Qa4 2.Qe8+ Bc6 3.Qe2#
(That was a Bristol. The white queen moved in the same direction with the rook, on the e-file).

If 1...Qxa6 2.Qe2+ Bc4 3.Qe8#
(That was a Turton. The white queen moved in the opposite direction with the rook, on the e-file).

There is interesting by-play:
1...Qa4 2.Qe8+ Kxa6 3.Qxa4#
1...Qxa6 2.Qe2+ Ka4 3.Qxa6#
1...Qa5 2.Qxd5+ Ka6 / Ka4 3.Qxa5#
