King wandered too far, now there's mate in 3 in the middle of the board. Can you find it?
Just a correction about notation: Turns are always counted starting with white. If it is black's turn, you have to indicate it with 1... (or the turn number if you know it), and the next white's move is 2.
The correct notation would be
1... c5+ 2. Kd3 Re2 3. c4 R8e3#
Huh, hadn't seen that before. TIL
which Rook is able to go to d2? and how does it block d4, d2 & c2
Whoops, had a typo there.
