It's too late now, but I wonder if I missed the vital point/direction with :w22:

This way, B takes the UR corner, but W cuts off B's center stones (in sente?).

EdLee's next move is what I am curious about. He could consider "a" or "b," for example.

Initially, I thought that I would first make the following exchange before responding to :w28:

. However, I decided to leave this aji in place for the moment, waiting to see what EdLee plays first. Besides, I am not entirely convinced that White would have to connect at :w2:

. A response at "a" might follow instead.

This push might be too much from EdLee. Here are the moves I am currently considering:

White's last move is designed to gain even more strength against the Black group on the right in exchange for pushing Black along the 6th-line and for significantly stabilizing Black's position on the bottom. If Black simply responds at "a," "b," or "c," White would have to prove that the attack he could generate above would adequately compensate him for Black gains below. I am not convinced that White could do that. However, Black can also decide to tenuki, reinforcing the right group and attacking White's moyo on top. This would entail a local loss on the bottom for Black. If Black tenuki-ed a move ago, the loss would be very large. However, this might not be the case now.

Let's look at "a" through "f" in more detail:

1. "a"

B . . . . . . X . . . | $$ . . . . . . . . . . . . | $$ . . . . . . . . . . . . | $$ ------------------------[/go]

This move works well with :bc:

. It also essentially eliminates various reductions White could try, such as at "g."

2. "b"

This move is greedier than "a" but leaves more aji for White to try to exploit.

3. "c"

B . . . . . . X . . . | $$ . . . . . . . . . . . . | $$ . . . . . . . . . . . . | $$ ------------------------[/go]

This is the standard reply to White's push. However, it does not work particularly well with :bc:

, leaving White with a reduction at "g" and possibly even at "h."

4. "d"

This move is the aggressive response. White could cut, as indicated below, resulting in a chaotic fight. Here is how a related pro game continued:

Notice that Black would have greatly benefited from having a stone at "i" as in the present game. However, also note that Black has a stone at 4-4 in the bottom-left corner which is preferable to a stone at 3-3 for the purpose of attacking White's group.

This type of play is completely antithetical to my initial plan of playing this game. However, if I can prove to myself that White would suffer losses from such a fight, I might go for this move.

5. "e"

The extension from the right group at one of the points at "e" would completely stabilize the Black group and would also make White's influence in the center useless. If I were to play like this, I would first need to make sure that the damage I would suffer on the bottom of the board would not be too great. Here is a possible variation:

This does not look too bad, especially since Black gets sente. Maybe White can play better, though.

6. "f"

The idea behind this move is to remove aji at "k" after which Black can most likely get two eyes locally. A possible sequence to demonstrate:

White stones cannot escape.

As can be seen from the above, I have many options to consider and much reading to undertake. I'll have to sleep on it.

I believe Black group on the right not to be in any serious danger at the moment. Therefore, there is no need to take a loss on the bottom to reinforce that group.

As for how to respond to White's previous move, perhaps all the options I mentioned in my previous post are good. In the end, I decided on the most ambitions of them. Although I will need to be constantly on the lookout for White cutting at L6, my move expanded Black moyo greatly and it increased Black's influence in the center.

I do not believe White can cut at L6 right now, as this leads to a clearly unfavorable fight for White:

Black can next decide between "a" and "b," but White would be in trouble in either case. The marked stone helps Black a great deal in this fight.

Hmm...

is very difficult for me.
I don't know how to judge the following continuation:

I also don't know how to judge the following... seems it's even better for B?

I was also considering the following move:

However, this would leave behind a great deal of aji associated with the cut at "a," letting White play moves such as "b" in sente.

I am curious to see what EdLee's plan is. Does he intend to follow up his last move with the following sequence?

This way, White would get greater influence in the center. However, the sequence is gote and leaves behind cutting points at "c" and "d." Moreover, thanks to the marked Black group, White's influence in the center has a limited value--as long as I don't let the marked Black group become too weak, of course. Thus, at least for the moment, I am unafraid of the indicted sequence.
