Award of KoBulChess TT 2012

 logo 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.

   Very good play with battery creation and ODT, but the idea is not original. This thematic complex is shown for the first time by Kostas Prentos in his 1-3rd Prize winner of the 1st Bulgarian Wine Tourney, WCCC Crete 2010.

   5th Commendation (Martin):

   1.Bd1 R:d1(bK=rB) 2.rBd5 B:e4(brB=K)#, 1.Rd1 B:d1(bK=rR) 2.rRa4 R:a2(brR=K)#

   b) 1.Kh6! Ke7 2.Rg8 Kf7 3.Re6 K:g8(wK=rR) 4.Rf6 Kg7#

   Another fantastic problem: chameleon echo mates in Rex Solus and only 5 pieces on the board!

   3rd Prize (Argirakopoulos):

 1.g1B b8R 2.Bb6 R:b6(bK=rB) 3.c5 Rb7#, 1.g1S b8Q+ 2.K:b8(wK=rQ) rQ:g1(bK=rS) 3.c6 rQa7#

   Durbar and chameleon echo mates on 2 corners of the board with only 3 pieces – great!

   1st Hon. mention (Vysotska):

   1.S:a6(wK=rR) Bd3 2.Ka3 rR:a6(bK=rS)#, 1.S:b5(wK=rB) rBe3 2.Sa3 R:a3(bK=rS)#

   Ideal mates, aristocrat and interesting change of functions.

   2nd Hon. mention (Argirakopoulos):

 a) 1.Kh7 rS:h2(bK=rB) 2.b1B rSg4 3.Bg6 rSf6#, b) 1.Ka8 rS:d4(bK=rR) 2.b1R rSe6 3.Rb8 rSc7#

   Phoenix, Durbar, model mates, self blocks.


   Commendation (Balasubramanian & Seetharaman):

   a) 1.e1S Kb4 2.Sc2+ S:c2(bK=rS)# [3.rS:c2(wK=rS)?? self-check]

   b) 1.e1B+ Bb4 2.Bc3 B:c3(bK=rB)# [3.rB:c3(wK=rB)?? self-check]

   Commendation (Manolas):

 1.Re2 K:e2(bK=rR) 2.rRb3 Kd1 3.rRd3+ Kc2#, 1.Re3 S:e3(bK=rR) 2.rRh7 Sf5 3.rRh1+ S:g3(bK=rB)#

   Another masterpiece by the current world champion of the fairy genre! Four corners play – all pieces on a1, h1, a8, h8 changes their phases or leave their places! Sacrifices of the white Queen follow to change of phase by the wKa1 and creation of two systems of Dentist mechanisms – diagonal and orthogonal, where the black forward pieces of masked batteries (B and R) execute a double function – unpin of white N and self-unpin on the mating move through change of phase by the white KoBul King in N-status. Black self-blocks on c8 and b7, model mates and good position - Meredith.

   A rich thematic complex: Zilahi, diagonal-orthogonal play, reciprocal captures, creation of batteries. I hope that in the future will be possible to see it realized without zero-position.


Many thanks to all participants and congratulations to the awarded composers!

Excellent problems. Award finalised in record time (just 22 days)!
+3 #2 seetharaman 2012-04-23 05:17
Problem 20 (Second prize in the Miniature section) is wonderful. But does it qualify ... being in four moves ?
+6 #3 Manolas Emmanuel 2012-04-23 07:41
Thanks to IJ Diyan Kostadinov for amazingly fast decision.
Congratulation to all composers!
+6 #4 dkostadinov 2012-04-23 16:02
Thank you Ram for your remark about problem No 20. In beginning I really thought to announce the tourney for 2-4 moves because it looks very promising in fairies (for example as the Alaikov MT which is also organized by KoBulChess website, or even WCCT Fairy theme is in 2-4 moves), but in the period of announcement (the middle of 2011) the computer check of KoBul Kings still was not deeply tested, so I decided to make it in 2-3 moves. It looks like 2-4 moves are really somehow wrongly remembered so Crisan, also I during preparing the award or anybody else - all we aren't saw this mistake. But I believe that this wonderful composition deserve a Prize and I hope that all participants will be agree that it can be accepted for the competition...
+5 #5 dkostadinov 2012-04-23 16:06
Thank you all for your comments here and via emails. The judges of fairy tourneys know that this is difficult task especially when the entries are so many, but I believe that the people deserve to receive an awards as soon as possible, so I tried to do the best of me to prepare and publish it without delaying.
+1 #6 Diyan Kostadinov 2012-12-10 14:07
Paul Raican pointed out that the basic thematic content of problem n.29 can be realised without KoBul Kings fairy condition in following way:
white: Royal Leo d5, Rd7, Bf7, Pa4, b5, d2, f4, g5, h3
black: Royal Leo g2, Rb6, Se2, Pa7, b4, b7, e7, g6
H#2,5 2 sol (9+8)
1...Bg8 2.rLEe4 rLEf7 3.rLEe6 rLEh7#
1...Rd8 2.rLE:d2 rLEd7 3.rLEd6 rLE:a7#

Well, Paul is right that now the problem is without using of fairy condition, but in my opinion using of KoBul Kings in the original problem n.29 is better, because the play is more dinamic and the position is more clear.
+2 #7 R. Ganapathi 2013-06-13 09:56
Playing thr' some of the awarded problems I found Black pieces idle in one solution. eg
Pr.3 (3rd Prz) Sol.a)Sb7,Rf3 b) Re5,Bf7 and
Pr.8 (2nd HM) Sol.a)Ra5,Be1 b) Re8,Sb8
So, I would want to know the criteria in deciding what is economy in a Fairy composition as I am only keen to improve my composing skill.
+2 #8 Diyan Kostadinov 2013-06-14 03:41
Dear Ganapathi, thank you for your interest and your questions. Of course the useless black pieces in some phase is a weakness, and it should be avoid if is possible, but unfortunatelly sometimes it can not be happens and can be accepted. Even in orthodox helpmates we can see many problems with idle black pieces in some phase.
The idle white piece is even more bad weakness and usually the problem of this type should be not accepted (awarded). In both problems you mentioned the thematic complex is very nice and in my opinion they deserve to be awarded even with this weakness. Till to the date of the tourney pr.n.3 was one of very few composed KoBul Kings problems with all moves as thematic captures. This is difficult and beautiful.
But I repeat - even if sometimes the idle black piece in some phase is acceptable, it is unpleasant and you should try to avoid it. By the way - the idle pawns in some phase usually are something normal and can be completely accept.
+2 #9 Ganapathi 2013-06-15 05:25
I get it now.Thanks a lot giving your time for the explanation.
