Group B – h#2 ,
Helpmate in two moves
Judge: Borislav Gadjanski
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
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.

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
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).
