The diagram to the right shows a nine stone handicap game where White has played just one stone. How does this effect the nearby framework stones and links?
The corner framework stone is the weakest because it has only two ways of connecting to another adjacent framework stone and each of these routes is under threat. White 1 gives the added strength needed to legitimately invade at least one of these links. The symmetry of the situation is such that both links must be considered as equally weak.
A symmetrical reply at A appears the most logical. First it strengthens the weakest framework stone. Second it helps the framework connection equally to either side. However it does still leave the possibility of disconnection on either side.
A reply at B or C is perhaps the best tactic. Again the weakest framework stone is strengthened but this time giving a strong framework connection in one direction. This anticipates that White will dive into the large gap on the other wing. This is OK because, with the added strength, Black can anticipate attacking the invading stone and/or white 1 on a large scale and thus connect by slicing through or killing the white invaders en masse.
Although D and E are not bad moves per se, neither are they in the full spirit of GCS. The reason being that they give equal emphasis to the side framework stone as to the corner which is at odds with the correct framework evaluation.
