Dominique Forlot found a bug in the beta version of Natch. Some
solution where not found in a special case. Here is a SPG that is not
solved by natch-3.0-beta.
1.a4 b5 2.axb5 Bb7 3.Rxa7 Bc6 4.Ra1 Ra2 5.b3 Rb2 6.Ra8
The bug involved:
- the conflict of trajectories of the rooks.
- the capture of the pawn at its home square.
- the presence of a spare move (because Natch doesn't find that the rook
must make a switchback to open the column to the other rook).
The bug is now corrected in the version Natch-3.0-beta1, which is
available at the usual place: http://Natch.free.fr/Natch.html
Have fun composing !
