A full night's sleep does wonders to a man's mind. I don't know why I was so greedy yesterday, desiring sente so much as to tenuki from a weak group, but my sanity has returned. I'm grateful it took Hades so long to make his last move.
A question one might ask is: would my group die if I tenuki'd right now. The answer is "no." Between what I have on the inside and what I have on the outside there is no doubt I could get two eyes. White cannot seal me in with one move and I have at least one eye on the inside. My group, for all intents and purposes, is alive.
However, I do not want my group to "just live." That is pointless. To have 20 stones live with 2 points between them is so sad. I fought with 13 and 15 to get out of the corner. Why should I forsake my stones now? Why should I allow white to seal me in on the outside?
I watched Nick Sibicky's lecture on the first game of the Lee Sedol vs. Gu Li series. He talked all about when to tenuki. And now I look at this board and the answer seems so obvious - do not tenuki from a weak group. Because I believe I can get something more valuable than sente. I get move 3 in the following diagram.

I am out. I am in the center. And I am aiming at 'a'. This move aims at 'a'.
And if white should be so kind as to let me have it then he can't stop me from taking away all the white points on the bottom with the wedge at
, because that move makes 'a' and 'b' miai.

When I read this out I laughed. It is perfectly placed. And I need not worry about the left yet. White's group at D7 is touching a group that is about to become strong. After I am out in the center I cannot easily be attacked. Whereas I can play a move around the 'z' area later to split white apart and take away his points.
How often I forget the proverb - "Invade the moyo one turn before it turns into territory." I was going to be way too hasty. So I apologize for being inconsistent with my words. But I would rather be totally inconsistent with my words than totally inconsistent with my go.

was not good, because it doesn't gain anything significant for black, and it induces white to fix his weakpoint by playing A or one space above it. If white wants to allow the invasion, however, things suddenly become rather dicey, as white is quite possibly letting himself be split into two weakish groups in an area of black strength. Black can even push at B and then follow up with A, since it would be pretty painful for white not to respond to B, and if he takes A, he's still not making a gigantic territory.
