Let’s consider this situation which is complex because for the black stones we have problems of connection, so the idea is to sacrifice some of them and save the others. Let’s start with the K2 and we’ll get an answer in G2 but the idea is to save the other ones so we go to G1 and after that of course to E1. So we have a position which allows the saving of the left stones because for the white it’s impossible to approach this from the right.
