From the Shishida/Nariyama book where they talk about the historical Aiki
"The examples of Aiki include: "A situation in which two people stand facing each other", "When facing an enemy, this gets to the point of Aiki, waiting and seeing how one beats the other", "It is important to avoid fighting directly with an opponent's ki"."
This was actually from an older source. I think it was presented as the first usage of 'aiki' in a Japanese document.
Too bad I don't know where I saw that, but it was not considered a favorable situation, as I recall.
