I made an oversight in thinking that White would capture the stone. That's OK, though. We end up at essentially the same point as we were in before I tenuki-ed. I would really like to play on the left side now, but I need to assess just how much damage I stand to suffer on the right side if I don't reinforce my group there. Right now, I am reading the variations after White plays P14.

In EdLee's case, I would have played on the 3rd line, as indicated below. This would make White much safer from an invasion. Is EdLee worried that if he plays low I might get to build a moyo in the center or does he think he can play on the 4th line and keep the territory, too?

I am not absolutely certain of the way he plans to carry out this threat, though, so I may be mistaken.

The L17 option of The Intrepid seems rather slack, to be honest. It's quite gote and almost invites black to strengthen himself by poking at the gap. In addition, if white gets undercut, he can expand his eyespace with the atari at S16.

That looks amazing! Seeing the position in this form elevates the game to a whole new level.

Yea, it's a little more 3D.

I decided against playing at M10, as I previously intended, because I could not find any satisfactory way of dealing with WO10, which White could play at a later time.

Essentially, it is as if one of my hands were tied as long as that group is not secure. I could not safely invade the top and I would always be at risk of falling under a severe attack. Thus, I Lee-Changho-ed this one.

I'll think a bit first, but my plan was to invade at 3-3 in response to a wide extension down the left side as in the game or at "a."

In addition to the move in the game, I also considered invading at K17. However, the White structure is stronger than it would normally be in such positions due to the marked exchange, reducing the value of the invasion.

Finally, since my group in the center is strong now, I am not worried about giving EdLee influence. The value of territory should now be greater than the value of influence.

Takao Vol. 2 just arrived recently --
Size of Stones Post #52 -- with a small section on 3-3 under 4-4 (3 pages),
which I don't think was in Ishida. Perfect timing to study.
