It’s Your Move: daily chess puzzle #149

White to play and win

Uhlmann v Bronstein, Szombathely 1966

Solution

Examine all biffs, leads, as so often it does, to the solution: 1 Rb6! clears the f6 square for the N fork, and Black has no rescue check. So, for instance, 1…ab 2 Nf6+ Kf8 and rather than the prosaic 3 Ne8, 3. Qd6+! mates.
