This one is rather simple logic.

...and he is off and running, certain to connect southward or westward.

Moves 'b' and 'c' have the same problem, for if I play one, he plays the other, and I am running from behind, pushing the cart where it wants to go.

Move 'd' has no obvious ill effects. It looks like this

( Moves 3 and 5 probably would not be played. They are shown here just to demonstrate that black's connection is solid. Regardless, 8 gets out. )


For beginners:
Note that in the seven variations considered above, a major concern was not getting behind in a pushing fight, also known as not 'pushing the cart before the horse". See http://senseis.xmp.net/?PushingTheCartFromBehind for a description of this.

Also, note that a secondary concern has been the possible formation of new eye space. See http://senseis.xmp.net/?PlayAtTheCentreOfThreeStones

You can reject the trigger if you want, but I figured it's unlikely.


Hard not to point out the irony of this comment. After giving up the two cutting stones below, yet he recognizes that Joaz is "unlikely" to do the same in his trigger.

There are probably other options for Chew than Joaz's triggers. For example:

Letting him have 85 is out of the question. It is not one of the moves that I expected, for it rushes toward my wall and leaves gaps behind, both of which look good for me.

MHO provides new possibilities with his latest move. He is playing so fast and loose that it is possible to threaten to split him. Previously, it was a binary situation: either his group would be alive or dead. Now we have the third possibility of me threatening to split his group, and him accepting the offer, allowing me to kill part while the rest runs.

I'm tending toward '1' above because letting him have that point with '2 and '4' below looks bad for me.

As noted previously, if he gets this point, he is very close to two eyes. I'll settle for capturing 2/3 of his group and letting the rest run. I can still chase them.

Okay, I feel like I can't save all of that, and the three stones that look easiest to save might not be big enough. Regardless, this is huge for points, and just might be sente. I'm not happy with how I've been playing this game for a while, so I'd like to turn things on its head a bit. If I can, I intend to try to begin an attack on the bottom group. I don't know yet if I'll have to trade something for it, or if I can manage to stabilize the bottom middle stones with other threats. When it comes down to it though, I think I may need these points.

I'm going to take it before he notices that it is sente for him.
Now sente is uncertain. I'm threatening 'a'. He is threatening 'b', but I can live, and if I get too strong around 'c' while defending, he is in trouble in the middle.

For beginners:
There is a proverb that says 'A play on the border of two territories is worth twice as much.' My move not only encompasses territory for me, but it threatens to invade his. It has value as an offensive move that enlarges my territory, and as a defensive move that reduces his. So it is worth twice as much.
If he had played there himself, he would have gotten the double benefit - in sente.

Decided I should start my attack from the outside. This threatens to make a base with my other weak group, as well as threatening to enclose the bottom white group. White will probably start running, most likely with something like K6. If W tries to just live locally, I have nasty moves like H2 and monkey jumps from the left, so it will not necessarily be easy. If white DOES run, I will have to decide whether to enclose, live, or try to separate, based on which running move he chooses.

My first inclination was to run out with a move like 1. The problem is that he then replies with 2. Now 'a' and 'b' are starting to look weak:

...so I have to reply with 3. He will play 4 without thinking twice. I probably will have to play 5 so that he does not. He will not miss the natural move at 6.

At this point I am in serious trouble on the lower side. I can almost certainly live in gote starting with 'c', but then 'a' is still a boatload of bad aji.

Looking at that and similar positions, I come to the conclusion that my upper side is not absolutely safe, and that I must prevent M8.
So I'm going to come in from the top, securing my northern territory, and sacrifice K3. ( It still has some aji left, especially if the play in the lower right corner results in me getting 'd' or 'e' )

He has little choice but to push westward with something like 'f' or 'g'. I'll expand westward also from 1, playing something around 'h'. He will swallow K3, and I'll try to connect to E5. If I can, I'll get more in the center than he gets on the lower side. If I can't connect, and get deflected northward as I push westward, I can get a rather deep invasion around 'i', plus a big center.
