The position and solution (as it is now) are attributed to
Henri G.M. WEENINK
Op de Hoogte 1918
in WinChloe database.

I have amended the Puzzle Objective to "White to play and win" but cannot edit the (composition-only) Stipulation: White to play and mate.

However, I am not sure that we should leave this as a live puzzle in case Weenink's study was originally incorrect. It might have been better to replace it with one of the later "corrections" and thus give credit to the "true" composer.

Why delete the puzzle?
Puzzle ressurected with correct solution.

P.S.: I hope a 'senior' admin can change the stipulation...

I have deleted this puzzle. The position and solution are exactly as given in "Study database 2000" so I assume that either a rather big oversight was made when Weenink composed it (1918) or some error was introduced as it has been republished over the intervening years

Several "corrections" of this same position exist, and include the only winning move Rc5! (instead of Rc7?).

The diagram is ok but the stipulation and solution are not!
There is no forced mate in 4 so stipulation should be changed to White to play and win. Move 3 in the given solution is wrong, allowing Black to escape and draw with 3...Kb6
