A well-timed problem, in CoVID19 times

We present today a well-timed problem by Nikos Mendrinos, awarded Greek solver, champion and new composer.

Condition: Because of the corona virus CoVID19 … the pieces must be kept in a distance from each other!
The condition is known as Anti-ContactChess or Anti-koko.

Problem-839


FEN: 4k3/b7/4S3/2q4s/K7/2p2Q2/8/1R6
#2, (4+5)
Nikos Mendrinos (GRE)
original

White plays and mates in two moves

Fairy condition:
Anti-koko


Condition Anti-koko: The moves, where one piece goes near another piece as in 1.Ka4-b3 or 1.Qf3-a8+ or 1...Qc5-a5+ or 1…Ba7-b6, are not legal and are prohibited.
The capture of a piece, as 1.Qf3xh5+, is allowed.

Tries:
{1.Qh1? / Qg2? Sg7!}, {1.Qxh5+? Qxh5!}, {1.Rg1? Sg7!}, {1.Re1? Bb8!}

Key: 1.Qe4! (waiting)
1…Sg7 2.Sc7#, 1…Sg3 2.Qg6#
1…Qc8 / Qc7 2.Sg7#, 1…Qc6+ / Qg1 / Qf2 2.Q(x)c6#
1…Bb8 2.Rxb8#

The white battery, constructed with wQ and wS with the key, can be opened giving double check. The defence of the black pieces is very limited by the Anti-koko condition.
