Today I share a beautiful endgame study/mate-in-4 that I have come across in a couple of books. Carel Christiaan Wilhelm Mann has placed black in zugzwang (1…f5 2.Qh4# or 1…Kf5 2.Qd5#) but has white to move. The resulting solution is sure to entertain!
White to move and mate in 4 (Georges Legentil, Le Journal de Rouen, 1910).
White to move and win.
