Changed position letter theme
One could say this theme demonstrates that there is no
conceptual difference between threat and variant.
(The "Böhmer" always knew :-)
As always I'm to lazy (and vain) to search for somebody
elses problem...
(= 10+8 )
2# (v) a) diagram b) Nd4-e6
1.X! (2.A) 1...u moves to v 2.B#
Move u to v:
1.X!(or X?, or Y!) (2.B) 1...v moves to u 2.A#
You see that if the piece (here N) stands on u, A is the threat and B the mate,
and if we move it, it's of course the other way round. (Here it's a bit more
complicated, as the thematic parade is already 2nd degree.)
