Historical notes
The 5-5 point has occasionally been used as the first play in the corner. The idea was experimented with during the New Fuseki era, often with the intention of forming a three-stone enclosure by adding further stones at the 3-5 and 5-3 points (pillbox). More recently, 5-5 point openings have been used with success by Yamashita Keigo (especially in the Gosei tournament -- a pun on the word go, which also means "5" in Japanese).
