How well is your derusting going, topazg?

Have a good game, both.


Let me guess. Was this the widest path?

I'll take this point, for the same reason. I wondered whether to go high to mix things up a bit and come up with a more interesting plan when he deals with the lower right corner later, but I have no real need to do so and don't know what he'd choose down there. I don't think I've ever played this opening before!

I'm going to have to think about this a bit, but I think this might be the sequence I play:

followed by a reduction in the hazy area.

I like this because:
1. He gets about 30 points, and I get about 10, but up to now he has invested 3 moves to my 0, so it is good for me.
2. white feels a little over concentrated
3. influence is less useful because we are playing cross, and because he has a 33 corner

Isn't the double low extension from the 4-4 point just a bit inferior?

@hyperpape: Yes, it's a bad shape and the 3-3 is a good answer. Shame that speedchase intends to make the mistake of not pushing at s6 first. White can probably punish by turning there instead of hanging connection. If he plays the correct sequence I like black's position a lot: 2 shimaris, and a corner and white overconcentrated thickness. But that order mistake is huge, might swing the game back in white's favour.

Also his plan to then immediately reduce is greedy and bad. Let white have those points, don't give yourself a weak group. It's better to just play some big fuseki point, such as h3.

Beware of triggers: think about each move you play!

Either block side is as good. I'll compare between the two double hane josekis and the standard extension joseki if/when we get there.

I'm also pretty unsatisfied with the position. I'm wondering whether R10 @ R6 would have been a bit less uncomfortable.

Hmmm. topazg wonders whether R-10 should have been at R-06, while I wonder whether it would have been better at R-11. ;)
