He will probably live in the middle easily enough by pressing me low. I'll pursue him by extending my right side group into the middle. As it gets stronger, then his lower right corner becomes a potential target.

If I'm strong enough in the middle, I can poke at it from below, and make territory at the bottom.

Implicit within that strategy was the unexpressed idea that the cutting stone at Q14 would become meaningless, and therefore expendable if he attacked:

...and that if he attacked, I would form a wall supporting an attack to the south, and steal sente while doing it.


But he played it much faster and looser up top, and now I'm rethinking that strategy. Instead of complicitly allowing him to live easily, I might be able to kill. But the problem with that is that my right side group could come under attack, particularly with the cutting sequence that I showed last post which catures - at least - the cutting stone at q14. So I want to be able to strengthen my right side group against that sequence - and similar attacks - before I go after his top side group.

If I had some exchanges like this:

...then I can play something like 'a', knowing that he can't hack through at 'b'.

However, what if his plans for his lower right group are more southern oriented? Like this:

...in which case I would do better with the previous plan of making territory at the bottom, making a token attack up top with the safer 'b' rather than the risky 'a'.


In summary, the long extension of his last move has opened up new possibilities. I need to know what he intends to do with his lower right group before I choose a new strategy or stay with the old one. There seems to be only one obvious eye-attacking move, so it costs me almost nothing to play it. Maybe I can get him to divulge something.

I'm either going to attack up top - and probably bet the game on the success of that attack - or I'm going to go for territory at the bottom. He gets to decide which.

Yeah, this was a pretty obvious threat before. However, MHO is playing with fire. I could definitely die here. However, if not, my group will get extra strength with which to threaten the middle white group, which isn't yet safe. Actually, because of this, I expect a play at 'a', to try to fix some weak spots. I'm bettting he's just leaning on my group to get a bit of stability in sente. Playing safe for the moment.

I'd like to extract my stone and leave him with no eyes, but it does not go well for me:

...I think that I can hold it all together.

So I'm going to delay the choice, and stake out sixth rank territory ( If I can get in a move like J6 or K 6 it could become real territory. ) It ups the ante considerably, for it threatens to deprive him of all of his eye space. It is too serious to ignore, and he has to strengthen his group. Will he choose to push north or south?

i have no idea why he choose to play this move.
black's only answer to this move is "a" and it will only hurt unstable white group.

This seems like the very least I could get here, and it gives me more of the corner than I would get, otherwise. I'm going to take the direction he blocks under consideration, and probably save the aji for later. That said, I could play something like this and not play 7, just to stabilize my group in sente.

I tenuki from the play in the upper middle ( where it is his maybe-one-eye group up top vs my maybe-one-eye group on the right ) to play a probe to discern his intentions in the lower right, and he replies with a probe that appears to test my intentions. So we are leaving many issues unresolved.
We are also rapidly increasing the number of semi-alive groups. This could come to a very precipitous end for someone.
I hope that it is not me.

But then, this is the kind of game that I want. I came out of the fuseki badly, with him getting way too much on the left side. Playing conservatively will not help me catch up. Playing winner-takes-all on the right gives me at least a 50-50 chance.

Am I the only one who thinks Joaz's sequences range from decent to normal to completely insane?

All other replies end up losing my threat to extract R7.

So blocking the to the east is needed, and it doesn't get him much:

Okay, gauging the best I can: I think this sacrifice and reduction is worth the possibility of losing my second eye on the right. If something has this much influence and one eye, it's going to be darned hard to kill. I'm not entirely alive or safe on the top, but all this influence will let me mess around with the bottom and right nastily. If I can seal my corner, I'll have 60 points on the left, which is probably enough to dance. If I can play somewhere like Q11, I may be able to set the right side running and turn Joaz's attack on its head. So the game is surely playable for both sides.

It is with fighting spirit that I offer my opponent... a 10-move trigger!

I'm not really strong enough to judge, but he seems to have a habit of posting sequences that trigger my "this can't possibly be right"-senses.

Me too.

i think it is ..can't understand - eye hurting - normal - insane - bad - decent in that sequence.
right after your posted he played decent move

Seriously, I doubt he passed. Can someone please look in his hidden section and see if he has the move there? Thanks.

As an aside, can anyone get O16 P17 O18 to work for any value of "working"?

(Edit; seems O18 directly is likely to just be a different move order)
