Helpmate in 10 (Black to move and white's 10th mates with black's help)

Agreed!

Quite impressive! Helpmate is one of the puzzle types you cannot solve on chess.com as you can only play moves for one side. In helpmates you really really really have to play the white and the black pieces. As a solver you do not identify with one of the sides but you represent both!
