Popeye bugs in the Fairy condition "Back to back" Those composing for the WCCC Japanese tourney please note that Popeye implementation has some bugs. Here are two I noticed:
Ex.1.
White : Kf8 Qg1 Black: Kh8, Be4 #1. Popeye gives single solution 1. Qg8#, but ignores 1.Qg7# !
Ex.2
white Pb2 Kc8 black Ka8 Ra1b1 #1 Popeye correctly gives 1.b2-a2 # If you replace Ra1 by black queen, Popeye gives ‘no solution’ even though the black queen cannot even now defend the mate (the queen cannot move as it has only pawn move after the available mate 1.b2-a2#). |

[EDIT: Oops, forgot to add 'cond backtob' to the file....]
The CVS version of Popeye seems to be working correctly, at least on Linux. I'll compile a new version later today.

pie whi kf8 qg1
bla kh8 be5

cond backtob
twin move e5 e4
end

Method I previously used on Windows to compile Popeye doesn't work anymore, and I can't get mingw32 working on my Linux laptop, so no windows binaries for 4.68 unfortunately.
[EDIT]: Well, I found out how mingw works after all. So here is a 32bit binary: http://sanguis.xs4all.nl/popeye |

Here's the windows binary i have compiled from CVS sources (input copied from Joost's post):

a)
b) bBe5-->e4
1.Qg1-g8 # !
1.Qg1-g7 # !
solution finished. Time = 0.212 s
It is an unofficial modified version, use at your own risk:
