Fiendish Moves #2

 Kupper – Leepin

Basel, 1954

White to play

 

Black has nothing to fear from 27 Qd8+ Kh7 28 Nf8+ Kh6 29 Qd4 Re2 when the position is equal.

     27 Nf8!

A brilliant move, and the only decisive one.

Richard Forster’s The Zurich Chess Club, 1809–2009 (McFarland, 2011) sparkles with such little-known jewels.

Zurich Chess Club

 

Dr Josef Kupper (1932–) is a Swiss master who retired from active play in the 1960s to pursue a banking career.  He won the Swiss Championship in 1954.

Here he dispatches a former world champion with another conclusive (but easier to find) knight-to-the-side move:

Euwe – Kupper

Mont Chaumont, 1958

Black to play

 

A curious position where the rooks and knight threaten to mate both kings.

Black strikes first:

     41…Nd1+ 0-1

It’s mate after 42 Kc1 Ra1+ 43 Kd2 Rb2+, because the knight covers the c3 escape square.
