"Attack and Defense" has a chapter on invasions into three-point extensions. In the introduction of that chapter, it confirms my suspicion held for quite a while, namely that 'for smaller frameworks there are standard josekis for invasion, cutting and making life' (quote approximately rendered from memory). In other words, there are standard sequences arising from attacking or defending keima, ogeima and nikken-tobi in places farther off from the corners. Some books have examples of such joseki, e.g. one volume of 'Learn to play go' shows the way to make life from a nikken-tobi on the third line. Question: where, if at all, can I find a dictionary of such non-corner joseki? Or is everyone supposed to figure them out for him/herself?

It is somewhat annoying when Many Faces of Go and GnuGo both respect me to the point of not even trying to invade such a framework, probably assuming that I could defend it anyway, while I am sure I would have at least a hard time doing so, supposing I would not just botch it altogether. I have noticed that I am becoming quite good in "imitating" proper Go play, making extensions I know the programs will respect and leave alone, even if I have no idea why do they work. I suppose this qualifies as forming bad habits.
