A Welcome to 2017 with cooperations

I will open the January with wishes for health and successes to all composers.

Let us hope that the new year 2017 will bring joy and happiness to all people.



Three compositions - cooperations of mine, belonging to fairy chess because they use grasshoppers, were published last year and I have learned about it this year.

I offer my thanks for the cooperation to Vito Rallo (with colours of Italy) and to Kostas Prentos (with colours Greece/USA).

The Grasshoppers are pieces - hurdlers. They see on a row or file or diagonal another piece - hurdle, and they jump on the square exactly after the hurdle. If this square is nonempty, it could only contain an opponent piece, which is captured by the Grasshopper.

Goodbye 2016

I will close this December wishing health and success to all composers.

Let us hope that the New Year 2017 will bring joy and happiness to everyone.



Two compositions of mine, belonging to fairy chess, are published in the Romanian e4e5 magazine, Nr.34, December 2016, p. 559.

The first is a helpmate threemover with fairy condition Circe : Black plays first and helps White to mate. In the meantime, any captured unit is reborn on its initial square (initial as in the start of a chess game).

The second is a directmate twomover with fairy conditions Circe and Madrasi, and also two fairy pieces Nightriders. We spoke previously about Circe.
Madrasi is a condition of paralysis : When two pieces of same type and different colour (wR and bR, wQ and bQ, etc) are threatening each other, then they are paralysing each other, until the end of threat.
The Nightriders are pieces of linear way of moving, with Knight steps.
In this composition all the tries and all the white moves during solution are done by the white king.

1.Bxh3(+wRh1) Rxh3(+bBc8) 2.Bf5 Kxb7(+bRa8) 3.Rxa2(+wBf1) Bxe2(+bPe7)#

Black sacrifice with the key. Reciprocal captures bBf1 and wRh3. Openings and closings of lines. Selfblocking.
In three moves the bBf1 must go to f5, and the wBa2 must go to e2.

Key : 1.Kxc3(+bQd8)! [2.Qf2# / Qd1# / Qe1# / Qc1#]
1…a1=Q/B+ 2.Kxb3(+bRa8)#

Themes Durbar (All white moves are made by the wK) and royal Option (Tries and Key are made by the wK). 
This active wK stops the Madrasi paralysings, capturing black pieces in its field. Only one from six capturings is succesful, while the rest five are tries with different treatments.
There are also other effects, as exposition of the wK to check, indirect Self-pin and unpins, Reciprocal pins, Crossed checks.

Playing with Composition

In this post we will start from a nice miniature by our friend Nikos Pergialis and we will enhance it with more variations.
A miniature has up to 7 pieces.
Adding pieces to it, the problem will not be a miniature anymore, which was a limiting factor for old chap Nikos, but it will get more variations, which is my goal.


Problem-825
Nikos Pergialis (GRE)
8/8/8/rS6/3b4/1Q6/p1K5/k7
(3 + 4)
#2
Try : {1.Qb4? [2.Qe1# / Qxd4#], 1…Bb2 2.Qxb2#, 1…Bf2 / Be3 2.Qb2# / Qc3#, 1…Bc3 2.Qxc3#, 1…Rxb5!}

Key : 1.Sc3! [2.Qb2#],
1…Bxc3 2.Qxc3#,
1…Rb5 2.Qxa2#

The key is quasi-sacrificial. It closes one line allowing one mate, and also supports the wQ for the second mate. There are three mates in total.

The pieces are relocated two columns to the right.
A wRb6 was added, to keep bK from escaping to the second column.
A wBb1 was added, to allow promotion of bPc2 to knight, stoping the threat. A bRa1 was need to stop some duals from occuring. When bPc2 captures, the wQ mates from square d1.
A bPe4 can capture the wQ with check, but then a wSe5 mates.
The bQ can deter the threat, but then wRh7 mates. The presence of this rook offers a try, which allows us to see the Pseudo-Le Grand theme.

Problem-826
Emmanuel Manolas (GRE) (after Nikos Pergialis)
original
7q/7R/1Rr5/3SS1b1/4p3/3Q4/2p1K3/rBk5
(7 + 7)
#2
Tries : {1.Rxh8? [2.Rh1#], 1…Bd2 2.Qxd2#, 1…Be3 2.Qxe3#, 1…Bh4 2.Qd2# / Qe3#, 1…Rxb6 / Rf6 / Rh6 2.Qxc2#, 1…exd3+ 2.Sxd3#, 1…Bh6!},
{1.Qd4? [2.Qg1# / Qb2#], 1…cxb1=Q 2.Qd1#, 1…cxb1=R 2.Rxc6# / Qd1#, 1…Rxb6!}

Key : 1.Se3! [2.Qd2#],
1…Bxe3 2.Qxe3#,
1…Rxb6 / Rd6 2.Qxc2#,
1…Qd8 2.Rh1#,
1…cxb1=S 2.Qd1#,
1…exd3+ 2.Sxd3#

The problem works with similar mechanism, as the previous one, only it has now 14 pieces and there are six different mates. 

There is also the Theme Pseudo-Le Grand : "Two threats (A, B) in two phases, reappear crosswise as mates after different black responses (a, b) in these phases".
In the present problem the relevant moves are as follows
1.Rxh8? [2.Rh1# (A)] Bh4 (a) 2.Qd2# (B), 1…Bh6!
1.Se3! [2.Qd2# (B)] Qd8 (b) 2.Rh1# (A)

Composer Cooperations (6)

It is very probable that there exist more compositions with recent cooperations, and if any Greek composers want to inform me, I will update this post. I select two of the cooperating teams for today.

Problem-823

1.Kf3 Rf1+ (0-0??) 2.Kg2 Rf3 3.Kxh2 Kf1 4.Kh1 Rxh3#

In one variation the castling is a good move, in the other it is not effective. The "wrong" moves are noted with double question mark.


Problem-824
Emmanuel Manolas (GRE) and Ioannis Kalkavouras (GRE)
3rd Hon. Mention, Moskovski Concurs 2016

It is a help-stalemate. Initially the Black helps a lot for his pieces to be captured, and at the end the White helps a lot tryin to avoid winning! 

The comment of the judge : "Circe, with nine pieces captured without rebirth! The essence of the problem : marching towards a stalemate trap, the bK passes from the rebirth squares of the black pieces, allowing the wS to capture all these pieces which would inhibit the stalemate, without any of them being reborn".

Cooperations of composers (5)

We will see here the result of a cooperation of Ioannis Kalkavouras and Emmanuel Manolas, aiming to the composition of a helpmate in three and a half moves (that is, White plays first) with the following restrictions :
(a) The White has got only a Bishop and a Knight.
(b) The white pieces, B and S, will form with pericritical moves a battery which will fire with double check.
(c) The black in two variations makes different castling and is mated in the eighth row.
(d) No replacements of pieces (for twinning) is allowed.

1.0-0 Sd5 2.Bh8 Bb3 3.Qg7 Sf6#
1.0-0-0 Sf5 2.Bb8 Bg4 3.Qc7 Sd6#

Here is shown the idea in simple form. The wB could be positioned on e2. 
The wK, to avoid checks by bR and bQ, could be only on columns b and e. But, with wKb5 the solutions are 1507, with wKe6 the solutions are 1283 and with wKe4 the solutions are 32. The wK is very well placed on b1! 
The white movements are not pericritical, they simply form the battery.
If we force the restriction h#3,5, then many unwanted solutions appear, 68 in total.

The nice movements of the wB are pericritical and the bishop forms the battery in both variations. But the two mates do not happen on the eighth row

1…Ke2 2.0-0-0 Se3 3.Bb8 Sxf5 4.Qc7 Sd6#

In one variation the white battery is formed by the wB moving clockwise, and in the other by the wS moving anti-clockwise.
The two mates appear symmetrical in the eighth row (vertical mirror, echo mates(0,4)).

Theme Elmgren

(Initial date of this post was 21/12/2015)

In this post we will see the Theme Elmgren under a different light. This theme is named after the Swedish composer Bertil Elmgren, born 25/05/1912.

In this theme, all the black pieces (3 or more), with a possible exception of the bK, are actively refuting white tries!
A try is an attempt by the White to win, but the Black has a unique defense.
The White has at least three such tries, and all the black pieces take their turn to refute.
With more black pieces on board, the probability all of them refuting a try diminishes, making it more difficult for the composer to achieve an Elmgren.
Likewise, the more the black pieces, the more are the tries, making the problem relatively more difficult for a solver.

Having all the black pieces struggling in defense, symbolizes a common battle where no one stays behind the trenches, waiting to see what will happen!
There are no idle pieces, simply blocking a flight or stopping an unwanted second solution.
Everything is useful and active!

I have published in this blog some problems containing the Elmgren theme.

A selfmate, with strip-tease.

Selfmate are the compositions where White plays first and forces Black to mate, while Black tries to avoid it.

Theme Strip-tease : One by one some pieces are removed from the chessboard, leaving a new problem to be solved.

This theme, Stip-tease, is contained in Problem-777 (see here) which has got a distinction in the World Congress of Bern.

Today we will see an easy selfmate. Black has a light-squared Bishop who can mate the cornered in h1 white king, and the matter is how can we empty the diagonal from the pieces that block (direct obstacles wQb7, bPc6, bKe4) or can inhibit the mate (possible obstacles wPe2, wRh5, wRg4, wBa4) the mate.

In these three twin compositions, White loses a pawn and a rook, one after the other.
In each occasion, sacrificing pieces and threatening the bK, White forces Black to mate in 5 moves.

Awarded chess problems by Greek composers, 2015

Awarded Compositions GR, 2015

(Last Update : 03/01/2016)

In this post we have gathered the artistic chess compositions of the Greek composers, which have earned a distinction in composing tourneys of the year 2015.
There were more publications, but here we are limited only to awarded ones.
(A note by Alkinoos: If some award is omitted, which is possible since I do not read everything, the interested composer is kindly requested to send to me the necessary information to append it in this anniversary post. Thanks!).

In twelve (12) international composing tourneys there were seventeen (17) awarded compositions, atistic creations of five (5) Greek composers (sometimes with co-authors).

We stress here a fact, seldom happening in Greece : This year we had organized here in our country one (1) international composing tourney : JT Manolas-65.

The entries to the composing tourneys are judged by a Judge and they get distinctions (by descending order): Prize or Place, Honourable Mention, Commendation.
In some interesting cases the distinction might be preceded by the word 'Special'.
The distinctions may be numbered or not.

Sentinelles : When a piece (Pawn excluded) leaves a square outside the first and last rows, it leaves a Pawn of the color of the side that played unless 8 Pawns in this color are already on the board.

The triple pin mate is achieved with the help of a fairy unit, the SuperLeo, which can capture over 2 hurdles. You certainly need an eagle eye and a sharp mind to anticipate the mate with three pinned units, of which two will be sentinels that will appear on the board during the solution. On the downside, the price paid by this ambitious achievement is the heavy position and the lack of interplay. Question: can anyone obtain a five-fold sentinel presentation of this splendid idea?

Adventure in composition with Andernach Lions

In this post we will observe the attempt for composing problems having specific fairy pieces, namely Andernach Lions.

Lion : Is a hurdle jumper, moves at Queen lines, jumps over a hurdle and steps on one of the empty squares (or captures a piece there) which are exactly behind the hurdle.
The "hurdle-color changing" Lion (or 
Andernach Lion) when passes over a hurdle changes the color of the hurdle (except it is a King or a neutral piece).


Last year we had seen, among the awarded problems in the World Congress on Chess Composition (WCCC) in Bern, the following problem with one Andernach Lion.
The composition tourney asked from the composers a helpmate two-mover with hurdle-color changing Lions. We had two ideas but the deadline was only three hours, so we barely had the time for checking one composition, the problem-776.

1.Re2-e5+ hLb2-g7(wRe5) 2.Kd8xc8 Re5-e8#


The Judge wrote : "Nice miniature. The white rook and Lion exchange functions in the mate".


The second idea lead us to the Problem-795. The idea here was to put the black Lions as epaulets from both sides of the mating piece, so they cannot capture it. This is achieved with Orthogonal - Diagonal Transformation, as you can see in the solution. 

The prominent composer Kostas Prentos, international maitre and multi-champion of Greece in solving contests, has moved to Uinted States of America, that is why his name is appended with USA.

b)
1.hLc5-g5(wPd5) Rb3-c4 2.hLb2-g7(wPd4) hLa6-h6(wBg6)#


For this problem we had many comments, mainly because the black pieces bRe2 and bBg6 stayed inert, waiting to change color. It is not forbidden for black pieces to stay inactive in some of the solutions (for white pieces this is forbidden), nevertheless the composition could be altered.


The composer Ladislav Packa had proposed to us the idea to convert the inactive pieces to Andernach Lions. In the following Problem-796, besides Lions (moving in Queen lines) we use a Rook-Lion (moving in Rook lines). To achieve what we want, we start with a white move, so the problem is now h#2,5 .

1…hLf4-f7(whLf5)+ 2.hRLd7-g7(bhLf7) Ke1-d2 3.hLe5-e7(wPe6) hLf5-f8(whLf7)#


Here there is Orthogonal - Diagonal Transformation and the idea of Lions as epaulets is well presented.


Since the moves have become 2.5, the question arises if we can make something different for helpmate twomover. I have tried the position which is shown as Problem-797.

b)
1.hLg5xc5(bPd5) Bg1-h2 2.hLc5-e3 hLf8-a3(wRb4)#


Here we see the Orthogonal - Diagonal Transformation, but not the epaulets, which may be abandoned. Black pieces are used that stay inactive in some phase (not forbidden, but not economical enough), and the solutions have not the same number of color changing.


Maybe I can do better. Let us try a new position.

Here White has minimal force, just one Pawn, but he can find the required forces to make two mates, one in an orthogonal way and one in a diagonal way. In each solution there are three changes of color.


Can this become better? The answer is yes.

1.hLb5-f1(whLe2) hLh3-c8(wPf5) 2.hLf1-f4(wPf3) hLe2-h2(whLg2)#


The composition is not in a twin form, it has two solutions.
There is orthogonal - diagonal transformation.
White has only an Andernach Lion. In each solution there are four color changes and they are all necessary!

Comment by Judge Michal Dragoun : Full analogy in recolouring of the pieces.
