Not counting the two spots where we each have a single stone touching, this is my last weak "group". Now the aim will be to make the little weaknesses in joppon's positions dangerous for him.

I wonder how I'll do that?

@Loons

Loons, when I play thhe crosscut in certain situations I get a (small) feeling of unease because of the difficulty of determining likely outcomes. In situations like this I simply wait to to see what my opponents do and then say: This is what I want from this position. And then I try to find a sequence that best approximates my desire.

Are there such things as crosscut joseki? Or perhaps you refer to joseki which feature such cuts. In the former case, it depends upon where they are played on the board, the positions of nearby stones etc.

To actually answer your question: I'm not sure that E5 is sente. But that probably has to do with my never having studied the concept. E5's relevance to my mind, is its effect on the centre. In taking the bottom left, Marcus has gained about 20pts. And is about 30pts ahead overall. However, black has so much influence that white will probably spend much of the rest of the game on the run, trying to live. My cutting stone, because of Marcus' choosing to take the corner has simply allowed me to take sente. From this point of view W78 was overplay? If something like below occurs and I was white, I would not be happy.

Aphelion:

now i wonder how to continue with black to gain most... i agree with Loons that white center stones are probably too heavy to be worth an effort to save them

diagram 120-1 shows what i consider a nice sequence for black. once white takes gote for settle his floating group, black stakes out a big territory with 'a'

i also considered playing 1 at 2, driving white the other way and finishing the sequence with 5, claiming the right side. i am eager to see how will white solve the situation
