It’s Your Move: daily chess puzzle # 22

White to play and win

Olsson v Buskenström, Dalarna 1962

Solution

The solution is almost forced upon white, since black has copious threats against the white's king. All white must do is make the most of the threat of back rank mate: so, specifically, the Re8 is tied to the eighth rank, so that 1 Ne7+! forces a king move.

If black moves his king to the f file, white takes on g6, and then checks away with his bishop or rook to improve his pieces, eventually closing the e file. So instead 1…Kh8 2 Ng6+ hg 3 Bg2!

White is able to keep control. There are some further minors tactics: 3…Bc4! 4 bc Re1+ 5 Bf1 Rf1+ 6 Kg2

and White wins: he is a passed pawn up, with the better minor piece.
