A new name to me, and already two quite good problems!
(483) An economical realization of a very Patrol-specific idea: Black gives his K access to a square by capturing the observer of a white guarding piece; White mates by re-observing that piece.
I suppose you must call both mates models (wSe4 does not guard d2/f2) even though two pieces are observing Rd2 after 3.Kd3? etc. The concept of model mate is not clearly defined in all fairy forms.
(484) I like it that both white pieces restricting the mobility of Black’s piece are also used to guard flights thanks to the attacks from that black piece; a very harmonious concept.
Yes.. two clear cut ideas realized with harmony and a light touch..
The idea of 483 – the WS and WB mutually activating each other has possibilities for extending into a cycle..
btw.. Bxc2 and Bxf5.. not Bc2 and Bf5..
As far as the white King plays no role (in both problems), I wonder if it would not be simpler to delete it (and of course to add “No white King” in the stipulation). Saying otherwise, is economy a stronger requirement than the traditional attendance of both Kings?
Hmm… an old question..
We just keep the WK in any odd corner.. so that it’s out of the way and doesn’t make a nuisance of itself..
Sometimes, we need to surround it with pawns and such..
Something like the vermiform appendix, i suppose.. more trouble trying to get rid of it..
Of course, the obvious solution is to find a use for it.. so that it earns it’s keep.. 😀
I remember our Parthasarathy ‘s a two part article (in our good old magazine “Crosscheck”) on the non-thematic uses of the White King ! (
Just a short note (because I am very busy right now):
I have discussed Nicolas’s question about superfluous kings in my paper
“Wozu eine Doppelmonarchie?”, feenschach: Zeitschrift für Märchenschach, Heft 151, Band XXVIII (April-Juni 2003), S. 74.
Two nice problems. Provacation is an interesting condition. Hope it might be implemented in Popeye in future.
It is implemented! But as many others is not included in the manual. I know it from Thomas – you can use “Provoc” for Provocation. I’ve tried, it works, and Popeye writes ProvocationChess under diagram.
Yes, you are right. I was APWin. It was not listed in it. But there is option to write the unlisted conditions also. Thanks.
