This week's problem takes us back to orthodox two-movers, with a brilliant
exploitation of the star-flight theme.
White has three tries:
1. Sc5+? Kd6/Kf6/Kf4/Kd4 2.Sb7/Qc6/Qb8/Sb3#, but 1...Be4!
1. Sxg3+? Kd6/Kf6/Kd4 2.Sf5/Sh5/Bf2#, but 1...Kf4!
1.Sxc3+? Kd6/Kf6/Kf4 2.Qxd5/Sxd5/Bxd2# but 1...Kd4!
Finally, there is the key, which changes all the mates yet again! 1.Sxg5+ Kd6/Kf6/Kf4/Be4 2.Sxf7/Sh7/Sh3/Sf3/Rxe4#
A Zagoruiko, with a total of 14 (!) changed mates! The fact that the key and
tries all involve checks probably explains why the problem received only a
commendation, but it remains a splendid achievement.
