Borislav_Gadjanski





Judge: Borislav Gadjanski

The thematic condition was the display of „antagonistic pairs“ of solutions in an h#2. This sort of theme contains elements of paradox in its basic definition, so it was interesting to see what would be the composers’ creative answer to this challenge.
The package that I got on the 20th May from the neutral judge, Marko Ložajić, blew me away. Twenty high-quality compositions represent a reponse beyond all expectations and a confirmation that the choice of theme hit the jackpot. In such a situation and tight deadlines it is never easy to make a choice and rank the compositions in a way that causes the fewest possible negative comments. When faced with a wealth of compositions that completely satisfy the theme, the taste, personal inclinations and prejudices of the judge gain in importance, and this is precisely what happened here. I had to eliminate a composition which I had long considered for one of the top spots, that is B-6 (Kg1/Kd5). The reason is the existence of a complete ideal predecessor (see Annex A, in the right column).
I gave advantage to those compositions, in which the antagonism in the strategy is clear and easily noticeable. The commendations are unordered.
Many thanks to Marko Ložajić for translation into English!

Thematic condition


Antagonistic pairs:

Two pairs of solutions in h#2 present some kind of opposite tactical effects. Composers are free to use their imagination with a help of following examples.


Example 1:
Fadil Abdurahmanović

3.Pr. Sakkélet 1997

white Ph3 Kf8 Re8 Bh4b1 black Pg6g5d4f2 Kf4 Bc4c1

h#2 4.1.1.1

1.Kf4-f3 Re8-e1 2.Bc1-f4 Bb1-e4 # 1.f2-f1=R Bb1*g6 2.Rf1-f3 Re8-e4 # 1.Bc4-e2 Bb1-e4 2.Kf4-e3 Bh4*g5 # 1.g5-g4 Re8-e4 + 2.Kf4-f5 h3*g4 #

In the 1st pair wR & wB support each other to allow mates on e4. In the 2nd pair wR & wB interfere with each other on the critical square e4.


Example 2:
Fadil Abdurahmanović
Živko Janevski

2.Pr. Problemist Ukraini 2015

white Ph5g4 Kd7 Rd6 Bd4 black Bg7 Kg5 Qb4 Pc7c5f5h3e2 Sc4c2 Rh7d2

h#2 4.1.1.1

1.f5-f4 Bd4-f2 2.Sc2-d4 Rd6-g6 # 1.Kg5-h4 Rd6-g6 2.Sc4-d6 Bd4-f2 # 1.c7*d6 Bd4-e5 2.Kg5-h6 Be5-f4 # 1.c5*d4 Rd6-d5 2.Kg5-f6 Rd5*f5 #

In the 1st pair of solutions black “liquidates” thematic white pieces. In the 2nd pair black “revives” the same white pieces through unpinning.


Example 3:
Fadil Abdurahmanović

1.Pr. J. Elbaz 60 JT 2017

white Qd2 Pa5d5 Kh6 Bg5 black Pa6b5c3 Kc4 Bf3c1 Sb2 Rg2

h#2 4.1.1.1

1.Kc4-b4 Qd2-f4+ 2.Kb4*a5 Bg5-d8 # 1.Bf3-d1 Bg5-e3 2.Bd1-b3 Qd2-d4 # 1.Kc4-c5 Qd2-d3 2.Rg2-d2 Bg5-e7 # 1.Bf3*d5 Bg5-f6 2.Rg2-g5 Qd2*c3 #

White avoids self-pin (see dual-avoidance moves) in the 1st pair. In the 2nd pair white allows self-pin (counting on unpinning by black).
