Award of KoBulChess TT 2012

I was very pleased to receive a total of 74 problems by 17 authors from 11 countries for the 1st KoBulChess TT 2012. The level of the tourney is high with so many entries with original and interesting thematic complexes!

In the announcement of the tourney I was written that the tourney consist of 2 sections:

Section A: KoBul Kings problems without any other fairy pieces or conditions.

Section B: KoBul Kings problems with fairy pieces (no other fairy conditions were allowed).

I had received so many miniatures, so finally I’ve decided to split the first Section, to separate a section for the miniatures. So the award is split into the following sections:

   -section A1: direct #/=, H#/=, S#/=, HS#/= problems in 2-3 moves and 7+ pieces with white / black KoBul Kings without fairy pieces or another fairy conditions;

   -section A2: direct #/=, H#/=, S#/=, HS#/= miniatures in 2-3 moves with white / black KoBul Kings without fairy pieces or another fairy conditions

section B: direct #/=, H#/=, S#/=, HS#/= problems in 2-3 moves with white/black/neutral KoBul Kings with other fairy pieces, but other fairy conditions are not allowed.

   Definition: KoBul Kings – When a piece (not a pawn) of his own side is captured, a King transforms into a Royal piece of the same type as the captured one. When the King is in the form of any Royal piece and there is a capture of one of the pawns of his own side, he becomes a normal King again.

   Captures are illegal if they result in self-check by the transformed King. Castling is allowed only if the KoBul King is on his initial square in the form of a normal King and if he has not already moved; however he may already have been transformed. In the case of capture by a King in AntiCirce he is reborn on his initial square and may castle. If the capture is by a King which is in the form of some Royal piece, he is reborn on the initial square of that piece.

   Participants: Pierre Tritten, Petko Petkov, Velko Aleksandrov, Juraj Lorinc, Vlaicu Crisan, Eric Huber, Kostas Prentos, Emmanuel Manolas, Themis Argirakopoulos, Ioannis Garoufalidis, Manfred Rittirsch, Julia Vysotska, Luis Miguel Martin, Jacques Rotenberg, S.K.Balasubramanian, K.Seetharaman, Cornel Pacurar.

Kangaroo or Lion ?

Kangaroo or Lion ?

This post is an anwer to the comment on The Main Accent: BATTERY-PLAY:

seetharaman says: April 22, 2012 at 5:35 pm Excellent imagination to show different effects with the similar settings of Nos.4 and 6. Can No.4 be more economical if Lions are used instead of Kangaroo.?

First of all – thank you very much for your deep analysis and your ideas! I appreciate your comments a lot! About the Lions: Yes, I can take off the white pawns (e5, g5) in case of Lions, but at the same time I won’t need to block the squares e2/d2 on the blacks’ second move. So, have to find some other idea for this move. For now I’ve composed 2 versions of the problem No.4 – with Lions (4.1) and with neutrals: Bishop-Lion and Rook-Lion (4.2). Of course, some more motivations are possible to the black knights on the 2nd move.

2 variations of problem No.4 from the “Battery Play” post:

No.4.1
Julia Vysotska
Version 4.1
h#2 2 solutions (5+7)
Lions: d5,e5
I. 1.Sxd5 LIe8 2.Sd8 Be7 #
II. 1.Sxe5 LIg8 2.Sc8 f7 #
Here the black knights on the 2nd move don’t block the King (as in No.4), but close the line of Ra8. The other thematic is the same.
No.4.2
Julia Vysotska
Version 4.2
h#2 2 solutions (4+6+2)
Neutrals: Bishop-Lion e2, Rook-Lion f2

II. 1.Sxf2 nBLh5 2.Sg6 g4 #
Here the black knights on the 2nd move don’t block the King (as in No.4), close the lines for neutral BL/RL so these pieces can’t go away on the mating move. The other thematic is the same.

The Main Accent: BATTERY-PLAY

The Main Accent: BATTERY-PLAY

I’d like to present you my another 7 problems, published at the end of 2011 – beginning of 2012. These problems are helpmates and fairies (h# and hs#) – my preferable genres for now. It’s possible to say, that the main accent of this seria is a battery-play, which is shown in all the problems in different modifications.

Some comments about the battery-play in the problems below

Helpmates:
No.1 – the indirect white battery, which plays along the 4th horizontal
No.2 – the creation and play of the white batteries B-R and R-B
Fairies:
No.3 – the black battery plays along the 8th horizontal and transforms
No.4-7 – the anti-batteries, which are possible only in the fairy problems
The interesting ideas in fairies:
No.6 – non-standard theme with the self-blocks of the neutral piece, which is used in the anti-battery creation;
No.7 – another rare theme – the preventive anti-battery, where the whites can’t prevent the mate as they can’t play on the thematic line – if they do, it would create a black anti-battery with the illegal self-check for whites.

In the future posts I’ll write more about these and some other non-standard themes and ideas which figure in my unobtrusive fairy-repertoire..

And now – to the problems…..

The non-standard Chameleon

Julia

April, 2012

My start in composition

I want to dedicate the first post on my site to the very first fairy piece I’ve got to know – the Chameleon (type Q-S-B-R-Q). I’d call this piece – my start in composition, as the first problem I’ve composed and even got a Special Prize, was h#2 with Chameleons for The 2nd BULGARIAN WINE Tourney in Jesi, summer-2011.

The current year, 2012, is also a special year for the Chameleon piece, as this year it celebrates the 50 years anniversary (the first definition of Chameleon with contemporary rules is published in Feenschach, 1962 by Petko A.Petkov, who has developed an old idea). I’m happy to congratulate the inventor of this peace in a way we see it nowadays, famous composer IGM Petko Petkov, with this great date!

I like this piece, a long time known, but still not so much used and studied, as it gives some interesting and non-standard opportunities.

And now – to some of my published problems…. with Chameleons, of course!
