I think you just push the king around on white squares, hope all three bishops eventually blunder off the same diagonal (come on), and promote that c6 pawn to a queen. That's not a very satisfying "mate" solution but I don't see anything more clever. Reading other comments, I see you'd also need to use the white king to guard the white pawn at c7 - I missed that - but even with that, you'd still need to hope that all three black bishops would go off that diagonal. Anyway, this seemed mostly about visual pattern recognition and thinking geometrically, visualizing vectors, seeing unblocked pathways. That's not how computers do it.

There's sort of a silly argument as to how you could get mate. If a computer is playing black, it reads the board as greatly to its advantage. So when it's coming up on the 50-move draw, it might offer you a bishop to take to prolong the game. It has such a material advantage, a draw "feels like" a bad outcome, so it's worth giving up some material to continue the game and go for the win. Which is a very computer way of "thinking". Once you take all 3 bishops in this manner, you promote the pawn and get checkmate.

  Once you take all 3 bishops it is a draw as black can't move any pieces.
