November 27, 2017 marked the 125th anniversary of the birth of Fedor Bohatirchuk, the Ukrainian-born Canadian chess master.
Bohatirchuk is probably best known for his excellent score against Botvinnik: +3 =1 -0. The second of those three wins was our previous Canadian Game of the Week: here.
While he never won the Canadian Closed Chess Championship -- he emigrated to Canada at the age of 56 and taught radiology at the University of Ottawa -- he did defeat players who did. The diagrams show positions from games between Fedor Bohatirchuk and four Canadian Chess Champions, including the two who won it the most:
