# Amateur Fuseki 4

Keywords: Opening

Could someone please comment on this fuseki? Above all I would be interested in general principles (e.g. the timing of making a shimari, length of extensions etc).

Moves 1 to 10

Andrew Grant: is premature. There is no need to invade this early. Better to make a second shimari at c. (It's possible that White should have played at c to prevent this.) Once is on the board I would like to play at d to deny Black a base. If Black jumps out to e, then White can extend to .

Double shimari, but....

Bill: makes a double shimari, but then is ideal for White.

Maybe it's wrong, but I hate to let my opponent make an ideal play. ;-)

Premature?

How about ? If , then and Black has prevented White's shimari. If is at a, then Black can be satisfied to have prevented White's ideal position on the right and can play .

Dieter: ... and amateur fuseki it is because no whole board matches this fuseki in a gobase search.

Comparable ?

So I did a right half board search and found 4 games, one of which has this composition. Notice that is not at 4-4 and not at 3-4. - followed. But there was one almost perfect match of the proposed diagram:

pro game

In this game, Black invaded with . The only difference here is the position of . Given it is in the opposite corner, a lot can be said for if is at 4-4, I guess. Still, one game is not enough a basis for proving ideas so we better think about it ourselves.

Double shimari, but....

I like a better than b because it is severer against the corner: I don't want b to end up lonely and weak as in Bill's diagram. I like c second best after a, because the continuation as in the first pro game White d, Black e would be better for Black if the left corner stone were at hoshi.

I think the "normal" reponse would now be "a" above but I wanted to experiment a little bit and played "b" - was that bad?

Isn't black in trouble when white plays at , since the ladder is bad for black?

Moves 11 to 20

Andrew Grant: Another way to play instead of above:

Moves 11 to 20

If Black plays the usual joseki he ends up highly overconcentrated because of the marked stone.

Moves 21 to 30

I was quite happy now for black - what do you think?
