The Problemist, March, 2013
Written by Michael McDowell
The March issue contained reports on two solving events, the ISC and
the Winton Capital British Chess Solving Final, won for the second
year running by Colin McNab. Awards included fairies for 2009
(judges Thomas Brand, Hans Gruber and Ulrich Ring), selfmates and
reflexmates for 2011 (judge Diyan Kostadinov) and the Norman Macleod
Award for 2010-11. Michael McDowell presented a selection from Eric
Zepler’s years in charge of the Selected More-movers column and
Browsing in the library covered the 1983 collection of problems by
Dr. Meindert Neimeijer, Honderd en één nacht. In the
Supplement Paul Valois discussed selfmates in two with reciprocal
change, and Geoff Foster showed a number of Shinkman two-move
miniatures. David Shire’s problem alphabet reached W for White
Correction, and David was himself the subject of Chris Feather’s
latest article on British helpmate composers.

Mate in 6
White’s knight is, paradoxically, a hindrance, preventing
a mate in two by 1.b8Q, so White spends four moves
1.d8S (>2.Sf7) Sd6
3.Se3 (>4.Sf5) Sd6
5.b8Q (>6.Qf4) Sd6
2nd Prize, Europe Echecs, 1976
Mate in 2
A vacation of e6 will threaten mate by the rook, and no
less than 8 tries by the bishop fail to self-obstruction. An impressive piece of construction.
1.Ba2? Ba1! (2.Qxa1?)
1.Bb3? Bc3! (2.Qxc3?)
1.Bc4? Qh3! (2.Sc4?)
1.Bd5? Bxc5! (2.Qxc5?)
1.Bd7? Sxc6! (2.Sd7?)
1.Bf7? Rg6! (2.Sf7?)
1.Bf5? e6! (2.Bf6?)
1.Bg4? Bb3! (2.Sg4?)
1.Bh3! (>2.Re6) and the mates obstructed in the try play now work.
1st Prize, Wola Gulowska, 2009
Selfmate in 2
A knight move will threaten 2.Be5+ fxe5.
Try 1.Sb6? (>2.Be5+ fxe5)
1...Bxf3 2.Qd5+ Bxd5
1...Rb2 2.Qc6+ Kxc6
1...Sc5! giving the king a flight at c6.
Key 1.Sb8! (>2.Be5+ fxe5)
1...Bxf3 2.Qc6+ Bxc6
1...Rb2 2.Qd5+ Kxd5
A very clear example of reciprocal change.
