Walter and Eddie were both plain ball strikers. As Fred Davis said, "Walter avoided using side as if using it would give him some sort of disease".
Walter was an outstanding potter - "the best long potter ever" (was a view held by Joe, Fred and Pulman) but his reluctance to use side meant that he often forwent ideal position. According to Fred's autobiography, Walter would make 30, 40 or 50 always with the cue-ball slightly out of position but keeping going because of his brilliant potting. Then he'd run away for safety. His long potting, although extremely consistent was mostly restricted to shot to nothings. He would rarely take on a difficult pot where there was a danger of leaving his opponent in if he missed.
In 1947, Fred tried to force the issue by taking on risky pots himself and paid the penalty. Walter, who had locked himself away in a friends loft for months of solo practice, was extremely sharp and took full advantage.
Thereafter, Fred decided that the best way to beat Donaldson was to take him on at his own game. By taking no risks, and, because Fred was generally the more fluent scorer of the two, he'd force Donaldson into taking on a few risky pots to get in. This proved a highly astute game plan by Fred but the downside was that it led to long bouts of safety and fewer large breaks. In 1948, several six frame sessions were running into 3½ hours duration. Bearing in mind, these were best of 145 frame finals played over 24 sessions (two weeks), they were the ultimate test of snooker endurance.
Fred Davis and Walter Donaldson met in EIGHT consecutive World Championship finals, with Davis winning in 1948, 49, 51, 52, 53 and 54 and Donaldson in 1947 and 50.
