It’s Your Move: daily chess puzzle #268

White to play and win

Klundt v Kestler, Volklingen 1970

Solution

For the second day running, I failed. I played 1 Rf7! thinking it was winning, but it loses; whereas 1 Nf7!! as played in game wins, but only by computer analysis.

White won in the game, because Black’s defence wasn’t the strongest, and Teschner’s analysis were human, not computer aided, so erroneous. I have posted my present analysis here.
