Perhaps G3 was not as sente as I thought :oops: Still it was very big for both sides and I do have some nice followups that I think are my privilege.

I think that the most important thing to do now is make a base for my lower stone on the right, especially since otherwise R8 is a beautiful multi-purpose move for Black. There are also long-range thoughts of connecting R7 to K4 if Black doesn't pay enough attention, though I imagine he will. I think that R14 still has some flexibility (e.g., invading at 3-3).

Needless to say, Black is still much better; all I can do is keep trying to play good moves and wait for an opportunity to turn things around.

I don't understand the tenuki. Now I can attack his stone.

Prevent white from connecting underneath. Planning to attack white and moving out to the center to reduce white's potential at the same time.

In case you players need any encouragement, I'm finding this game very interesting and glad it is still active.

Thanks for sharing it.

Well, this doesn't look good at all. I come back to this thread every once a week or so and then immediately close it in disgust. But I need to either resign or keep playing, and it's not over yet.

This move attempts to either connect to my stones below or support a 3-3 invasion.

If he takes the corner now, his three stones on the outside will become very weak.

Black's last move looks like rather odd shape to me. He certainly doesn't want to play at R11 now, and at some point in the future I may be able to, threatening a cut on either side. But not yet.

I feel like my main strategic choice now is what to do with my three stones in the upper right. My first instinct was to invade at R17, but although taking Black's corner away is big, it would probably effectively sacrifice those three stones. Even though they still have some aji, that seems like a lot to give away, especially given my (not totally intentionally) influence-based strategy.

Plan B is to start a big running fight, which is what I should be doing with influence anyway. Generally one of my weaknesses is to recognize when my opponent's stones are weak, and it took me an embarrassingly long time to realize that Black's three stones on the right side are not too strong!

One concern is that Black could end up fencing off the upper side during this fight, but 1) it seems just as likely that I will be the one to get in there first if Black has to spend time looking after his right-side group; 2) even if Black does do that, I still have R17; and 3) if we make side-by-side walls across the top, mine may actually make a good deal of territory in the center.

We'll see what happens, but increasing the variance of results by getting into a fight is probably what I need to do now.

Not sure I understand the comment about playing R11 and threatening a cut. Black would just connect on top, then there's no cut. Not sure what further moves would help make this a real threat.
