Daily chess puzzle: Check Mate #224

Another puzzle from Dragoslav Andric’s 1981 book “Matni Udar”.

White to play and win

Eggenberger v Schulmacher, Basel 1959

Solution

Quite nice today: combining various Purdy themes, like Black’s king being in a net, and Black’s queen being tied to defending e7, with John Nunn’s LPDO acronym, leads to 1 Qd2! and 1-0.

If 1…Qd2 2 Ne7+ and 3 Nf7 mate; Black is helpless. If 1…Nd5 2 Qb4 and now the N is tied to e7.
