Keys "s"=save "l"=load "b"=back once
Shatra -- Chess from the Altai region of Siberia. Captures are by jumping.
I had all pawns promote to queens.
I have not implemented all the fine points yet. Reserves still in the fortress can capture, to squares inside and outside the fortress, and I waived the requirement that they be placed at the next opportunity. I found this didn't make much difference.
There are bugs in the program. If it locks, hit "restart".
These are simple illustrations rather than strong opponents.
Bug reports? -- Thank you! Keep them coming!
