Dual avoidance in two main lines on second and third white move (1... Qe5: 2.Se6:+? / 3.Sb5+? and 1... Se5: 2.Sd7+? / 3.Sc4+) is an unusual concept. Also a good, rich by-play. [Milan Velimirovic]

Gallop of white horses and chameleon echo. [Author]

A wonderful selfmate with two analogous main lines and a full-length threat. Excellent and economical construction, especially the loose South-East corner. [Milan Velimirovic]

Precise building of white box around the WK while BK oscilates on d2 and d3. Not quite new, but always interesting for solving. This problem has not been computer tested - even on a 166 MHz Pentium I did not have the patience to wait the program to solve it. [Milan Velimirovic]

This problem has appeared, as original, in ST 6/1995, problem no. 886. Our solver did not cook it; I myself tried it with computer, too, but stopped after some hours. [Henry Tanner]
