⚛️ #about_Purdy
▪️ Cecil Purdy
▪️ Australian chess International Master
🔰 Cecil John Seddon Purdy was an Australian chess International Master, writer, and inaugural World Correspondence Chess champion. Purdy earned the Grandmaster of Correspondence Chess title in 1953.
🔘 Full name: Cecil John Seddon Purdy
🔘 Country: Australia Egypt
🔘 Born: 27 March 1906
Port Said, Egypt
🔘 Died: 6 November 1979 (aged 73)
Sydney, Australia
🔘 Title: International Master (1951)
🔘 ICCF Grandmaster: (1953)
🔘 ICCF World Champion: 1950–53
🔰 When Prudy was a child, he moved with his family from Egypt to New Zealand, and then to Tasmania, Australia, before they settled in Sydney when he was 12, where he was educated at Cranbrook School. While in Tasmania, one of his classmates was future film star Errol Flynn.
🔰 He began his chess career at the age of 16, and he soon decided to become a full-time chess writer and player. Initially an over-the-board (OTB) player, he soon began to mix OTB play with correspondence play. He was a four-time winner of the Australian Chess Championship, in 1935, 1937, 1949, and 1951. He won the first two Australian Correspondence Chess Championships, in 1938 and 1945. He also won the New Zealand Chess Championship in 1924/25. In Auckland of 1952, Purdy drew a hard-fought match with Ortvin Sarapu, at the time by far the best player in New Zealand. They were thus declared Australasian co-champions.

11.c4!
This looks rather anti-positional as Black can capture on c4 and secure the d5-square for his knight. If only chess was that simple! The text move is by far the most convincing way to open things up. 11.a4 b4 doesn't do quite the same job, as the queen cannot go to a4 and there still aren't any open lines.
11...bxc4 12.Ne5
Black now has difficulty preventing the queen check on a4. This checking idea, coupled with the bishop pinning the knight on f6, already leaves him in an uncomfortable position. The Ne5/Qa4+ combo (or even Ne5/Bb5+) is another useful theme to remember.
12...Be7 13.Qa4+ Nd7 14.dxc5!!
A great piece sacrifice to open the d-file and keep up the pressure. White could have retained the initiative with 14 Bxe7, but Nisipeanu spots that he has an even better way to proceed. Even if you see a good move, you should always be on the lookout for a better one!
14...Bxg5 15.Rad1 Bd5
Attempting to block the d-file. 15...Bc8 could hardly be considered as an alternative!
