Actually, I see now that I was wrong on the stalemate: Kxf2 would be legal, because it captures the Knight that was checking Kh1. Initially I hd that Knight on g3, but then it was not possible to pin the Hoplite on f2, so I moved it. An old-style General (R+N) on g3 would have done both the check and pin, but with G=B+K that does not work anymore. I guess a position that does what I intended is:
8 . . . . . R . .
7 . . . . . . . .

The fastest Spartan mate I could come up with, btw, it:
1. e4 Hfe6 2. Qf3 Cd6 3. Qxf8 Cb6 4. Qxe8# {White mates} 1-0
