Another day, another helpmate to solve!
Here's a really complicated one!
The Black pawn on Black's first rank moves like a normal Black pawn. It's White to move first.
Given that White moves to help Black checkmate themselves, find the quickest mates such that Black mates:
-With a queen
-With a rook
-With a bishop
-With a knight
-With capturing only four pieces
-With the king moving to c6 to support a queen giving mate
This is made to challenge your brain to think some more!
The fifth challenge is possible-I have tested it myself. It's all possible!
Good luck solvers!
