I think the protection would be better like this:

I like either P15 or SOMETHING in the bottom left quadrant =/. Can't figure out the right point for the latter, for the life of me.

Black is pretty solid everywhere. I think this would be a good time for O8, maybe? It strikes me as a good way to continue to reduce the White central framework. Again, just my gut instinct.

The contest now has become about who can get center territory. There are two groups with no definite eyes, and they will give both side a little leverage to make territory while attacking.

There are four major points in the center which both sides want:
H11 or nearby: The two eyeless groups would like to lean on each other. It is sente for both. The first one to do it gets influence in the center.
G7: Sente for white to invade the beginnings of black's moyo, and threaten the black dragon. Gote for black, but good for territory.
O8 or nearby: The juncture of two impending moyos. Gote for both, but big for both.
P15: Maybe sente for white to hurt the corner, good for white territory. Gote for black but provides nice anchor for reducing white territory in the middle or the right.

Of those four spots, I count 2.5 sente moves for white, one sente move for black. So it seems that black's short-term strategy should be to take the sente move, then play his best gote.

I'm not sure what that best gote is for move :b87:

, but my prediction for :b85:

is this sente move:

If true, it means that it is a good time to attack something.
If both are solid everywhere, them maybe it is time for territory grabbing.

BTW, at first glance, turning at N17 may look like sente. It is not:

It is a 10-point gote move on the second rank. White now has all kinds of forcing plays in the center.

If I were white, I'd start with this one:

It secures about as many points as dfa/H/H/Hblack's last move and it is sente.

Next time I should totally say "during the game I will make one fake move and you have to figure out which it is."

Posted: **Thu Oct 07, 2010 11:18 am**

I wonder if the move helps to blunt white's potential invasions of the corner?

Now I'd really want to connect like below. Even though it's going to earn me the "slowest move ever" award, it just gets so much nasty aji out of the way, any other move would feel like a half measure to me. After black plays there, he has his hands free to destroy white's center.

Still... isn't it amazing that we're already talking about black having to destroy white's center?
