Three more games to go, and the score between humans vs. Fritz 19 is now 1.5 to 1.5, after Robert Ris conquered the aggressive bull. Svitlana Demchenko's opponent is the turtle, an endgame aficionado. This animal is considered one of the more challenging Fritz 19 characters, and difficult to break. In the Sicilian Kan Variation, the Canadian WIM cannot really advance, until a material imbalance shows up out of nowhere! But things aren't getting easier .
