Add Another One And Then Abandon Both Of Them
This is a proverb nobody ever explained to me, so I'm not sure that it doesn't apply to something altogether different. But I use it to remember the sequence below, so this is at least one possible interpretation. Consider the following sequence (discussed by Sakata Eio in his book "The middle game of go").
Black has just played the crosscut at 1. Sakata calls White 1 vulgar style in the context of the discussed game, but that is another matter. There's plenty of occasions where this sequence is perfectly OK.
It is clear that the marked black stone is going to be captured. Nevertheless Black adds another one, in accordance with the proverb. White answers at 2 to keep the stones captured.
The thinking behind Black's line of play becomes clear in this diagram. Black has sente forcing moves at 1, 3 and 5. Compare this with an atari at 1 without adding the extra stone: White would capture and make a ponnuki, and that would be the end of it. Adding the extra stone increases the liberties of the black group. As White needs more moves to capture it, Black gets more kikashi moves. To note that Black must play 5 fairly soon, even though it smells like aji-keshi. This kikashi slows White down by a whole move, i.e. changes a white move at 'a' from sente to gote.
