White to play and win

K Dreyer v M Blieden 1940

Solution

Black has just played Qa6-f6, taking a bishop on f6, whereas gf would have been equal. Now, the pin is decisive: 1 Qc2 and if necessary 2 b4 win, fairly simply.

In the game, white accepted the draw offer that black made after Q*f6: Reitstein says white was short of time, and probably only saw that the natural 1 Rfc1 is nowhere near as good, since 1…Rcd8[] biffs the queen and unpins.
