When the pin doesn't pin
In the following game, Black forgets that a pin against the queen is only a relative pin. Thus, unlike an absolute pin (a pin against the king), the pinned player can ignore the pin if it is advantageous to do so. Compare the Légal Trap and Imbaud-Strumilo, corr. 1922.

Parr-Wheatcroft, London 1938
White to play and win
