I have been thinking a bit on how to handle early invasions as in the situation here (just for showcase, not a real game):
One could imagine that josekis have been played around other corners etc. The important point being that there are no other white stones close to the local area.
I have a few questions:
1/ Is this invasion legitimate at this early stage of a game? Or is there a way to punish it drastically?
2/ On forums and books (e.g. In the beginning), the upper attachment is usually recommended. However I don’t see a really good follow up for black after white hane. Consider for instance the first variation in my showcase review where white gets a ponnuki in the center : to me this result is at least even, or maybe better for white. Am I missing something?
3/ To me, the connection under (not shown in the review) which leads to a white ponnuki under, is even better as black gets strength towards the center and encloses white.
4/ After studying the 5 main variations presented in the review, I find the shoulder hit much more satisfactory. Black pushes white towards the wall and doesn’t leave cutting points behind. What do you think?
Any help and comments appreciated! Thank you very much in advance.
