After last week's blockbuster, a somewhat easier solving task, but a very elegant
This is an illustration of the Rukhlis theme, which requires that at least two mates in
the try- or set play phase are transferred to different defences after the key, whilst
the original defences acquire new mates. Thus, the try 1.cxd6? threatens 2.Qe5# The
defences 1...Sac3 and 1...Bb2 fail to the two corner mates 2.Qa8# and 2.Qh1#
respectively. However, 1...Sec3! defeats the try.
The key is 1.Qh8! this time threatening 2.Qh5 mate. Now the two unsuccessful defences
in the try phase both fail to new mates: 1...Sac3 2.Sb6# and 1...Bb2 2.Sxe3#.
Meanwhile, the corner mates seen in the try phase reappear after different defences:
1...Bxg6 2.Qa8# and 1...h1Q 2.Qxh1#. Finally, the defence which defeated the try fails
here to another new mate: 1...Sec3 2.Qd4#
Writing in the January 2003 issue of The Problemist, that great connoisseur of
two-movers, the late Lu Citeroni, described this problem as “A highly artistic,
crystal-clear rendering of the theme”.
