Marmorosh - Kniazer Match, 1931

This match, played in Haifa, was drawn (+4 -4 =2). Marmorosh gives 'the most interesting game' in his chess column (see source below). If the previous games made it seem that Marmorosh only publishes his victories, here he shows how he didn't win a won position, due to the Kniazer's resourcefulness. It is a nice lesson in back-rank mating threats (for both sides).
