I don't think 3...c6 is the best move for Black at move 3, Black is not forced to move a pawn at move 3. I believe the engines aren't playing the best moves in your pgn.
The intended solution is checkmate in 89 moves:

Since Huntsman 1 is the best engine to solve this position, I will give 60 seconds per move to Huntsman 1 playing both sides.
