Wait a minute, what about 1. Rc4?
Any Bishop move would follow my original line [edit: with Ke4 in place of Ke3], and any Queen move can be met with either Kg2# or Ke3# depending on the circumstances. Most importantly, if 1. ...Qxb5 2. Ke3# is checmate becasue the rook on c4 now blocks the delaying interposition.
Can anyone see a flaw in this?
hmm wait.. i think that works.. :)

Not two moves.
One move, right?
1. Ke3#
(am I wrong, cause I don't see it)
