Doubleislander's dedication

Doubleislander's dedication

The problems on this post were sent as a present to the composition contest [Jubilee Tourney Emmanuel Manolas-60] by a friend who prefers to be anonymous. We will name him/her as Doubleislander (from two islands).
The problems are quite simple, but the pieces are set in a way to represent the symbols J T E M 6 0 (initials from the name of the tourney).
We thank the Thrilling Anonymous!


(Problem 429)
Doublislander,
dedicated to JT Manolas-60,
original,
Helpmate in 2. Condition : Circe.
h#2 Circe (4 + 8)
[8/3prssb/5k2/5r2/5b2/3P1K2/4QP2/8]


With condition Circe, the captured piece is reborn on its initial square (example : the wQ on d1).


(Problem 430)
Doublislander,
dedicated to JT Manolas-60,
original,
Helpmate in 2. Condition : Chameleon - Chess.
h#2 Chameleon Chess (3 + 7)
[8/1pppkp2/3b4/3p4/3P4/3S4/3K4/8]


Helpmate : Black plays and helps White to mate.
With condition Chameleon - Chess, the moving pieces are transformed (i.e. the Knight moves and becomes Bishop, the Bishop moves and then becomes Rook, the Rook moves and then becomes Queen, the Queen moves and then becomes Knight).


(Problem 431)
Doublislander,
dedicated to JT Manolas-60,
original,
Selfmate in 2 moves.
s#2 (5 + 8)
[KSrb4/s7/qpp5/k7/pRPS4/8/8/8]


Selfmate : White plays and forces Black to deliver mate.


(Problem 432)
Doublislander,
dedicated to JT Manolas-60,
original,
Helpmate in 2 moves.
h#2 (3 + 10)
[8/2R3K1/2bp1pp1/2r1k1q1/2p3s1/2P3p1/8/8]



(Problem 433)
Doublislander,
dedicated to JT Manolas-60,
original,
Helpmate in 2 moves. Condition : Madrasi.
h#2 Madrasi (5 + 8)
[8/1PB5/p2r4/b7/pPp5/k2R4/rsK5/8]


With condition Madrasi, if two dissimilarly coloured pieces of the same kind (i.e. wR and bR) are mutually threatened, then they are paralyzed and the only power they have, whilst the threat is pending, is to paralyze each other.


(Problem 434)
Doublislander,
dedicated to JT Manolas-60,
original,
Helpmate in two moves. Condition AntiCirce.
h#2 Anticirce (5 + 7)
[8/3pp3/2r2R2/2b2P2/2P2S2/2k2r2/3sK3/8]


With condition Anticirce, the capturing piece is reborn in its initial square. The captured piece disappears.


The solutions will be posted here in a few days.

A study by Libiurkin and one (more) imitation

The first study comes from the collection [1234 Modern End-Game Studies], and is a composition by M. S. Libiurkin. In this pretty study White mates in 23 moves, but in the meantime has promoted five pawns to Knights and has allowed to Black three Queenings. (Unfortunally, this study is cooked, because the promotion 1.d8=Q! leads to a shorter solution).

The second study, by Manolas Emmanuel, contains no pieces, only pawns. The goal is to show the Phoenix theme, in triplicate.

In the two studies the mechanism of Knight production is similar, the road to victory is different.

Theme Phoenix : A pawn is promoted to a piece which was previously captured.

The composition is a tough job!

Solving Contest ESSThCh 2009

At the large hall KAP-PA 2000, Peraia Thessaloniki Greece, the Union of Chess Clubs of Thessaloniki and Chalkidiki (ESSThCh) has organized preliminary Youth championships Κ 08 – 16, and also some athletes were honored. Among others, Kostas Prentos received a special prize because he is Champion of Greece for eight continuous years in Chess Problem Solving.

In Wednesday, December 30 2009, the First Solving Contest of ESSThCh for 2009, with Judge Kostas Prentos, took also place.

Comments by the Judge : "The solvers had to solve six problems in two hours. I tried to select relatively easy problems, but not succesfully because the No.2 problem presented great difficulty to all solvers. Ten solvers tried their hand, some with relevant experience, the most for their first time, and the general impression was that they liked the experience of the contest.

Winner was Kleanthis Vafiadis with absolute grade 30/30 in 83' minutes. Kleanthis is a strong player and has a long exposure to chess problems. He had earned distinctions in other contests, as a young solver in 1989 at a contest of Municipality of Athens, and later in 2000 at a Thessaloniki solving contest. I believe that he can achieve a good placing in the all-Greece solving contests.

Second was George Dalaklis, with 26 points in 118'. George also is a strong player, but as a first-time solver he ranked admirably.

Third was Elias Kakousatze, with 20 points in 109'.

The winners were awarded, the first with a cup, the next two with medals."

The ranking of the solvers is the following :

(1) Vafiadis Kleanthis, points 30 (minutes 83')
(2) Dalaklis George, p.26 (118')
(3) Kakousatze Elias, p.20 (109')
(4) Mimikos Stelios, p.12 (120')
(5) Konstantinidis Lazaros, p.11 (87')
(6) Lykoudis Kostas, p.10 (109')
(7-8) Peskelidis Stavros, p.03 (120')
(7-8) Ermeidis Panagiotis, p.03 (120')
(9) Alevizopoulos Panagiotis, p.02 (120')
(10) Zevgolis Nikos, p.01 (120')
