At ply 19 the score is 16.6 and at ply 20 crafty fails high again. IMHO >Ke6! is even easier to see from a human perspective. > >Kind regards >B. Bauer >sc Can you give me the line please. At the moment I have only draw with Kd6 and Ke6: 44.Ke6 Kd4 45.Kc6 Ke5 46.Kb7 Kd6 with 47.Kxa7 Kc7 draw. Same motive with 44.Kd6. Another idea 44.Ke6 Kd4 45.Kf7 Ke5 46.Kxg7 Kxf5 47.Kxh7 Kg4 48.Kg6 Kh3 49.Kf5 Kxh2 50.Ke5 Kg3 51.Kd6 Kf4 52.Kc7 Ke5 53.Kb7 Kd6 and so on.
