If you had a Java-capable browser, you could play Siberian Chess here. Chess from the Altai region of Siberia.
Captures are by jumping.
Clink on the link for the rules. 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.
