THE GREATEST THING SINCE BOBBY FISCHER!
Here is a have that could be played:
e4 k4 e5?? k5 Bc4 Qxf7 and black is mated.
It is true black could have played d4 instead then move his king to d7, but, like with scholars mate, it would be way too easy to beat beginners.
@sacrificedStoat black can simply play kf7 and brown plays qf2, if white takes blacks king, brown takes whites', (or maybe even qf2 taking whites' bishop. If green had played m4 on move 3 and black, qe8, then brown is now threatening ql1 and green's king is gone.) The rules are that each color still plays on with all their pieces so long their aliies' king is alive, so the game would be interesting.
On the contrary, in this format there is no scholars' mate, since both kings must be killed to win.
