Square Hall the 1950 final moved to Blackpool Tower Circus. Fred Davis and Donaldson met in the final for the next two years, with Donaldson winning in 1950, 49–42, and Davis in 1951. Following a dispute between the Professional Billiards Players' Association (PBPA) and the Billiards Association and Control Council (BACC), members of the PBPA boycotted the 1952 championship. The BACC thought the championship should be primarily a matter of honour, and financial considerations should come second. As a consequence of the boycott there were only two entries, Lindrum and McConachy. McConachy had played in the recent News of the World Tournament but had performed badly, losing all eight of his matches. Although Lindrum did not play in the News of the World Tournament, he had been receiving more generous starts in recent handicap tournaments and had even withdrawn from the 1950 Sporting Record Masters' Snooker Tournament in 1950, complaining about his overly generous handicap. Lindrum won the championship, reaching a winning 73–37 position early on the tenth day. World Professional Match-play Championship (1952–1957) Having boycotted the official championship, the PBPA established their own championship called the PBPA Snooker Championship which attracted ten entries. Fred Davis and Donaldson were given byes to the semi-final stage, and met again in the final, held at the Blackpool Tower Circus, as Davis won 38–35. A second such championship was played the following year, referred to as the 1953 World Professional Match-play Championship, with the same finalists. Played at Leicester Square Hall, it was tied at 33–33 at the start of the final session but Davis won 37–34. The pair met in the 1954 final, held in Manchester, their eighth successive final. It was the most one-sided of the eight finals, Davis taking a winning 36–15 lead early on the fifth day. Fred Davis met John Pulman in the 1955 final at Blackpool Tower Circus, with Davis winning 38–35. Davis defeated Pulman again in the 1956 final, but did not enter the 1957 championship. Pulman defeated Jackie Rea in the final to win his first world title. Challenge matches (1964–1968) With the approval of the BACC, the championship was revived on a challenge basis in 1964. The first contest was played in Burroughes Hall, London in April 1964 between Pulman and Davis, with Pulman retaining the championship after winning 19–16. Pulman won two further challenge matches played at Burroughes Hall, beating Rex Williams in
