Another problem for an easy Reitstein day

White to play and win

M Hebden v T Andersson 2013

Solution

This took me longer than it should. I knew that the solution couldn't be 1 Bd5- too simple for someone to select it as a puzzle- and yet tried to make it work, then tried bad moves like 1 Rf3, and moves such as 1 Rg3.

Fairly random process really, shame to say.

Eventually I refocused, and applied Purdy principles. Examine all biffs means 1 Rc3+, 1 Rh8+, 1 Bd5 and 1 Bf5+! As soon as I saw the latter, I knew the problem was cracked, with 1…Kd8! being black's best, to prevent 2 Re8 mate, but, then examine all biffs again 2 Rd7+!, which is visually hard to see, but wins of course with 2…Kc8[] 3 Re8 mate.
