The aim of X-Zugzwang -- where X can be mate, stalemate, check, capture, etc. – is achieved when the side on-move:
- has one or more legal moves that achieve X; AND
- has no legal moves that fail to achieve X; AND
- is NOT in check
You could then go on to explain the abbreviated terms MateZugStalemateZugCheckZug and CapZug, and their corresponding stipulations: #z=z+z, and xz(Author)

Thank you Paul for this explanation of the interesting stipulation which you use in your fantastic fairy original with very long maneuvers by the wK! (Diyan Kostadinov)

67 could be extended with one move. +wPb3, -bPc4, solution: 1.- 82. as in first version then 83.b7-b8=B 84.Bb8-a7=R 85.Ra7-a2=Q Ba1-b2=R +
+2 #2 Alex 2012-11-18 11:47
Diyan, Patrol Chess and KOKO (used in problems 71 and 72) are not explained yet in "Definitions" section of the site...
+2 #3 Diyan Kostadinov 2012-11-18 12:17
Thank you Alex, Patrol Chess and KOKO (and Anti Take & Make too) are included now.
Paul, which version of your problem n.67 you prefere? The original one is with two Rook promotions, but the new one is with one move extended (if you need it for some task).
+3 #4 Pierre 2012-11-22 09:31
64 : it should be noted that priority is given to Anti Take & Make by WinChloe
+2 #5 Diyan Kostadinov 2012-11-22 19:45
Pierre, actually the question about the priority of using fairy conditions is very important, but there is not official answer.
In my opinion will be the best if the author have option to select which of the used fairy conditions should be considered first, second etc. This can be indicated with the order of the conditions under the diagrams. What is the opinion of the other composers about that?
But this will be very difficult (and probably impossible?) for the programmers to include this option into the chess programs.
So we should test our problems with the default parameters. For example: in the combination Take & Make and Anti Take & Make the second one is considered first by default in WinChloe (as we seen in n.64); in the combination of Circe and Anti Take & Make the Circe condition is considered first etc.

No.70. I think the name should be "Grushko"
+2 #7 Diyan Kostadinov 2012-11-23 03:04
Quoting seetharaman:
No.70. I think the name should be "Grushko"

Thanks Ram, corrected.
+3 #8 paul 2012-11-24 14:28
@ Diyan: I prefer the version in 85 moves (because b4 and d4 are guarded by Chameleon c5 only).
+2 #9 paul 2012-12-10 21:04
67 used a matrix from ... 1955:
Charles E.Kemp
The Fairy Chess Review, 1955
White Ba8 Sb8 Qc8 Ra6 Pc6 Pd6 Pg6 Pa5 Pe5 Rb4 Bd4 Pe4 Pg4 Sb3 Kf3 Pf2
Black Kd8
This is the oldest standing series-mover length record.
