Internet Composing Tourney: Netanya 1999



Netanya 1999


An orthodox twomover is required, where a thematic
try has one threat and two black refutations. These refutations reappear
in the solution as black defences. The first defence allows the try’s key
as mate (Vladimirov effect) while the second defence allows the try’s threat
as mate (Dombrovskis effect).


    Try: 1.A? threatens 2.B#
    Black refutations: 1…a! and 1…b!

    Solution: 1.X! (threat or zugzwang)
    1…a 2.A#
    1…b 2.B#

Doubling the theme and/or a combining it with
other ideas is allowed and welcome.
