Cordingley puzzle 77

White to play and win

Solution

One of the most straightforward puzzles. The first move is obvious, or, if it were not, following the routine of 'examining all checks' would find it, since 1 Bh7+ is the only check. Then 2 Nf7+, 3 Ng6+, 4 Qh7+, and the only somewhat hard thing to do is to visualise that with his King on f8, Rf7, Be7, then 5 Qh8 is not check, but mate.

A single line, forced, combination.
