| | (1) Posted by Hauke Reddmann [Thursday, Oct 13, 2022 22:42] | Please improve my problem From the Morse task book (German notation, too lazy :-):
J. Morse, The Tablet 1965
(= 10+6 )
1.Ld5! (2.Kc4#,Kc5#,Sd3#)
1...Da4+/Da5+/Da6+/Dxc6+/Dxa1/Dxh8
2.Kxa4#/Kxa5#/Kxa6#/Kxc6#/Kxc5#/Kc4#
(1...Da7 2.Sd3# etc.)
Maximum duel bD/wK. The disadvantages are obvious.
Here is a new matrix I found without the *thematic*
disadvantages, but it has even more disadvantages:
H. Reddmann, Augsburger Allgemeine 2021
(= 7+8 )
1.Ta8! (2.Txa7#) Dxf6/Dxb6/Dc3+/Db3+/Db4+/Dd4+
2.Kc5#/Kd5#/Kxc3#/Kxb3#/Kxb4#/Kxd4#
(1...Db5+ 2.axb5#)
A version where White at least has to think
about how to fire a half battery:
(= 10+9 )
But there is still no try with only one refutation.
I'm dabbling with the matrix since decades, but
I don't find a decent setting. I entice you to
dabble too; you'll soon find out how many side
conditions the matrix forces. (Especially
annoying is that LxD may not be a dual mate.)
Can you do it better than me? A version with
no uncovered checks (like Morse's problem
achieves) I'd see as sensational. | | (2) Posted by Kevin Begley [Friday, Oct 14, 2022 20:22] | Looks like a job for...
