Yochanan Afek, International Grandmaster of chess composition, has been providing us with articles for decades. He lives in Amsterdam, where Sagar Shah caught up with him and conducted a 90-minute interview, discussing some of the great problem compositions that we have from him. We have the puzzles in a replay board, where you can follow the discussion, using the built-in engine to answer residual questions you might have. Very entertaining and instructive.
