The value of two moves in a row
Difficulty: Advanced Keywords: Opening, MiddleGame, Strategy
There is a pro game with an unusual situation in which for some time white can play two moves in a row and can choose any time during the game to do it.
Game featured in an article "The Value Of Two Moves In A Row" by Matthew Macfadyen in the British Go Journal, number 90, 1993. It's "one of (his) favourite professional games". I (Malcolm) don't know if we can reproduce Macfadyen's comments, but the game itself should be OK.
The game is Okumura Yasushi (Black I think) vs Omori Yasushi, in the final of the Shodan section of the 1987 Kisei.
Black has killed the white stones, but has the threat of two moves in a row to deal with. White ends up resigning at move 252.
