3437 enclosure



There really ought to be a good reason for playing this way, rather than enclosing the corner conventionally. But this enclosure is more common than one might think: certainly in conjunction with the Chinese fuseki or mini-chinese, but also when the left side has special importance.

If White plays here next, there are a number of ideas.

Hosai's choice

W1 was played by Fujisawa Hosai. This is a special technique: but now White can push at a with quite a good feeling.

Not good?

White probably doesn't get away with playing W1 here; Black almost certainly chooses this enclosure in cases where W5 is too heavy. Of course Black could also pincer; but the question is where black+circle ends up (and White at a looks like a useful kikashi).



The other normal corner approaches are seen.
