CHESS PUZZLE. MATE IN 2.

Its a clever puzzle. The black rook/bishop combinations mean any move he makes is bad news. If he moves one of them one square it blocks the other. If he moves a bishop all the way in or moves the pawn forward that blocks an escape square for his King and he can be checkmated. Finally the king cant move and neither can the knight.
So all white needs to do is make a move which changes nothing (there are a few of these in fact) and then win after blacks move.
Thats if I understand it right.

BLACK MOVE.........e5.
or rather e6.

BLACK MOVE.........e5.
or rather e6.
or ...........Bc6+
1...Bc6+ refutes my move, but 1...e5 is impossible, and 1...f5 (if that's what you meant) fails to 2.Qd6#. And 1...f6 (if that is what you meant by 1...e6) does nothing to prevent the mate, so still 2.Nc7#.

If, 1. Rxa7..e6 2. Nc7+..Rh7xc7 no mate in 2.
If, 1. Rxa7..e62. Qd6+..Kf6 no mate in 2.
If, 1. Rxa7..Bc6+ impossible mate in 2.
Hope this answers your question.
The key move there is Bc3. No other possible solution.


if ..Bxc6+, then Rxc6 is checkmate!
If you look at the position carefully, you will find that the only White piece that can make the first move is the bishop. Good puzzle.
