Daily chess puzzle: Check Mate #254

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

White to play and mate Black

Book v Kopenen, Finland 1961

Solution

Slightly harder than recent days, but not by much. 1 ef! is a move that begs to be analysed, even without Purdy’s mantra examine all biffs and after 1…Qe2, both 2 f7+ and 2 Rg7+ win, though 2 f7+ is cleaner.
