YABS - an easy chess problem

[borogovio]

This is a rather easy chess problem - however, many chess programs that defeat me easily can't solve it, so I've used it to test them.

Black plays and wins.
Note: the board is in normal position: the white's side is down - the pawn's movement is upward

Well, its not mate in 1, or even 2.

Right for the moment

That is one of the accepted notations (except for a '-' instead of a '->', but it is easily understandable.
You should provide the movements of both sides. If black starts with c3-b5, white has to move necesarily a5-a6. Then c8-b8 is not a valid movement ...

Ok, sorry I deleted my post quickly realizing my mistake, lets try it again:
c3-d5, a5-a4, d5-c7, a8-a7, c7-a6, a7-a8(?) & c8-b8?

Arg no worky either!
Ok I give up.
