I've been playing through one position(diagram)/day. Now at #33.
In diagram 5 Colle-Grunfeld Carlsbad 1929 the following position is reached White has Kf4,a4,and h4. Black has Ke2,a5,and h5. Sources say Grunfeld resigned here. Book says it's drawn after 1...Kd3 2.Kg5 Ke4 3.Kxh5 Kf5. Book says Grunfeld likely saw that but probably missed 4.Kh6 Kf6 5.h5 Kf7 6.Kh7 now 6...Kf8 falls to 7.Kg6
book says Black draws via 6...Kf6 7.h6 Kf7 (7.Kg8 Kg5). I offer 6.Kg5 wins. I tried contacting newinchess.com without success. Feel free to try it yourself .
