Felix Sonnenfeld Centenary Tourney
Felix Sonnenfeld Centenary Tourney
To commemorate the 100th birthday of the great Brazilian composer Felix Alexander
Sonnenfeld (March 18th 1910 – Feb 12th 1993) a theme-tourney is announced:
A Helpmate in 2 is required showing the following theme:
A white or black piece 'A' stands, at a certain stage, on the intersection square ('x') of
two line pieces 'B' and 'C'. 'B' and 'C' can be both white, both black, or mixed colours
(black & white). In both phases 'A' moves away from square 'x', opening the lines of
'B' and 'C' simultaneously and landing on different squares in each phase. Then, in
phase 1 the thematic line of 'B' (only!) is closed again by any move of White or Black,
whereas in phase 2 the same happens to 'C'.
Remarks:
a) Acceptable are set-play, multi-solutions, variations (e.g., 1.2.1.1), duplex and any
kind of twinning except zeroposition. No fairy pieces/conditions.
b) Pawns are allowed as thematic pieces.
c) The opening and closing of the thematic lines may occur on any move.
d) 'B' is not supposed to close the thematic line of 'C' on square 'x' and vice-versa.
e) An anticipatory closing of any line to be opened later is permitted.
f) A cyclic execution with more than two phases is allowed. When the lines of n
(thematic) pieces are simultaneously opened then at least one of these lines must
be closed again in each phase.
g) Doubling (or multiplying) of the theme is allowed.
