what is a direct reflexmate?


reflex mate, got that...semi reflex mate, got that too...

I chanced upon Michel Caillaud's G190 (dr#3)in the 2001-3 FIDE Album. After a little investigation, this is a direct reflexmate noir(black). It has the feel of a H#2.5 1.2.1.1.1. What is the exact definition of a dr#? Are there other examples? When was this condition first shown?

Your first question is answered in the same Fide-album on page 617.

thanks, that helps!! I get it...pardon the humor...it's a direct reflexmate! I'm trying to reason out how/why selected the conditions for his problem. He uses a lot of Einstein and Alsatian together to rule out a lot of moves along the way and afterwards. throw in the cavalier majeur and dr#3 you have a lot of square pegs and round holes...but it looks like it's all needed to form the correct batteries and arrange the correct blocks or guards around the king.

Thanks for interest, Eugene.
The goal of the problem was to honour the memory of Jean Zeller. He was an Alsatian (Alsace is a region in France).
The idea was to pack in a single problem all 4 fairy inventions by him, that he presented in articles published in diagrammes and feenschach.
That is how the "variations" were selected.

What a fascinating story about this problem Michel! Quite an evolution...and you truly combined these all in a very clever way. Alsatian and Einstein marry beautifully together. I know that Zeller created Alsatian but not the others...
