I have added a few more things to this page that I found in Variant Chess magazine, issues 22 and 48. There is more information about the history, a note that the Bishop attacks the (4, 4) space by two different paths allowing it to issue double check by itself, and more information about endgames. I was thinking that a Bishop pair probably won't be able to mate but that is not correct. In fact, even if the orther side has a Knight, according to Variant Chess issue 48, the Bishop pair will still mate in at most 18 motes. I have not verified that move count, but I have verified that KBB forces mate against KN. The outcome of KBN vs. K is still unknown.
