My 50 most epic checkmates. Part 2. (11-20 / 50)

oops sorry 19 was fantasy. - There is a forced mate there after allowing Queen to promote.

17 !!

horse: holds f1.

1. doesn't let the other queen move leftwards, so queen can't take pawn.
2. supports the pawn and horse, so king can't take neither of them.

supporting 2 pieces and at the same time prevening an enemy piece (of equal strength) from moving horizontally.

Puzzles of mine:

Epic horse!
