30... Rg5?
Black should have tried to keep his counter-chances with 30...h5!

B) 31. Rd4 Rf6 32. Nh4 Rf2 with a double-edged game.

7.f4!
I have a slight lead in development, and the Black King is in the center. I go out of my way to blast open lines of attack so that I can take advantage of these factors.
7...Be6
Black places his Bishop on a nice square.
Playing 7...Nd7 would make it very hard to develop this piece in the future. And 7...exf4? 8.Bxf4 Be6 9.0-0-0+ Nd7 10.Nf3 would leave the Black King without a safe haven.
8.Nf3 Bxc4 9.Bh3! f5 10.b3!
I don't want to waste my time taking back that pawn on e5. Instead, I prepare to place my Bishop on b2, where it will create real threats along the a1-h8 diagonal.
10...Bb4 11.Bb2 Bd5 12.e4!
With 12.e4, I continue my strategy of ripping open the center to help my better-developed forces.
12...fxe4 13.0-0-0!
I seem to live for development, but this temporary piece sacrifice works because of the poor placement of the Black King and the vulnerability of the Black Rook on h8.
13...Bxc3!
Black stops me from taking on d5.
14.Bxc3 exf3 15.Bxe5 Nd7 16.Bxh8
I win the Exchange and use my material edge to win the game (Seirawan).

11...c5!
A farsighted pawn sacrifice. Bishops like open positions and Short immediately tries to open up the a1-h8 diagonal.
It was possible to prepare the ...c5 break with 11...Nd7 12.Bc2 Rc8 13.h4 c5 14.d5 but Black is somewhat more cramped compared to the game.
12.dxc5 Qe7 13.Ne4 Nd7 14.Bc2 Rfc8.

⚛️ #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.
