Judge Ivan Soroka 07/2023:
"A problem of a logical character, in view of the try 1.Qb4? axb4+ 2.Ka2! It is clear that White must occupy the a2-square with his bishop; but after 1.Ba2? Black is stalemated. 1.Qf1! Kd2 2.Rd1+ Kc2 3.Sd4+ Kc3. Now Black has the move 4... b5 at his disposal, which enables White to block a2. 4.Ba2! b5 5.Sxb5+ Kc2 6.Ra1 (rook switchback) Kd2 7.Qe1+ (queen switchback) Kc2 8.Qb4 axb4#. An elegant problem with double Bristol and switchback of three white pieces presented in a technically skilful way."
