Is there a term for making a half-hearted attempt to capture an un-capturable group so you get some free forcing moves before playing submissively and going back to live locally? Here was a fight that occurred in a 1kyu game on KGS a couple hours ago:
I’m only a tiny bit stronger than the players in this game but taking the hane at O9 looks extremely beneficial for *white and negates the need to connect submissively on the second line if black doesn’t defend his two stones at O7 & O8. Here’s a link to move 41 where this local fight occurs:
I’m mainly interested if this concept has a name, since I can’t think of a good name for this concept in English other than “taking your forcing moves before connecting” which sounds clunky and doesn’t really capture the idea that if your opponent ignores your new threat, then his old threat was purposeless. (similar in theory to forcing your opponent to defend and further invest into a “sunk cost” of a previous bad move)
(Typo: I meant the hane is beneficial for white – I had originally written for black)
Yes, the concept you describe is called “kikashi before defending”. You make beneficial sente moves before defending because they might not be sente after defending. However in the example you show it doesn’t apply because o9 just works to break out and fight and there’s no need to defend.
I may mention an old book from Mattern (German champion in older times) in German “timing” , [der Zeitpunkt] aimed more to advanced players but really interesting.
