Strategy and Thoughts

Tactics and Variations

Normally extending is correct, but there's the following:

I'm certain "a" is supposed to work in some situations, but I can't quite remember how, and if I play it out, get it wrong (or find that this is a situation where it doesn't work!) I lose out badly.

If extends, so will I, if he captures, I'm going to connect solidly, aiming at the following:

Edit: No, I'm not, that's silly. If I was going to let him connect, why play the corner probe in the first place. I don't like playing for the ko because he can cut instead of fight a ko, but how about:

It's that or "a" probably. I should have gone for the corner

Bleh, that's a nonsense move too, it doesn't work. I'm going to ko it.

Further thoughts:

I'm such a numpty. The next move should be the key point, and the whole purpose of playing on this side in the first place:

Now I may be able to rescue those stones to kill the top edge with "a", or if Black plays to stay safe, I can get "b" instead. If I manage to get "c" as well, I've made another 50 or so points in the middle. That gives me about 130 points, so as long as I can keep Black below 60, I'll be fine. When this middle fuseki-ish-thing has finished playing out, I'll count.

This seems better for black, but probably white is still okay (at least white can live: 7 takes, and then white has an eye at 'a' and miai for an eye at P18 and at 'b').

Tactics and Variations

I either extend or take the stone in atari. The second diagram feels more favorable, but I think taking the atari is proper-er. But I was really 51%/49% on this.

I've swapped around the prisoner counts because they were confusing me (I think the other Malkovich games had the number as the number of prisoners that side has managed to capture, not had captured - that way it can be easily just viewed as "bonus points for that colour" I guess)

Score and Counting

So making up some borders, and counting the top left as equal to komi, white's central moyo is worth about 35 points.

My right side is worth 28 points. Bottom left is worth 11. White's bottom is worth 8. I'm not counting the top for either side since it's not really resolved yet. And counting the center black stones as mostly dead.

So given these boundaries, white wins by 4 points (give or take). That doesn't count getting raped in the end game, of course. So these boundaries are not something I want to aim for.

Strategy and Thoughts

So these are the points which I considered.

'a' aims to split the white stones on the left from the white stones on the right. Really a key weakness of this white shape.
'b' looks to solidly connect to the black stones on the top.

'c' destroys any white territory on the side. But I don't think that's an issue anyway. So probably not a necessary move at this point in the game.
'd' expands my territory while cramping any hope white has of making territory on the side. It does everything 'c' does and more.
'e' attempts to force white into a family feud. But if the group doesn't escape very well it just becomes heavy.

'f' tries to break in to white's moyo a bit, but it isn't doing so from a position that is all that strong to begin with.

Of these, 'a', 'd', and 'e' are the only ones I think merit further inspection.

Okay, but not as good as the one above (less big move).

My weakness in the corner prevents me from really capitalizing on this one.

So 'a' seems like the best move.

This is the game sequence. I agree with daniel_the_smith and feel that white unnecessarily gave away all the aji in the corner just to play :w7:

in sente. I would recommend :b8:

as shown over a; it is honte and makes the corner absolutely secure.

I say that :w5:

must extend at :b6:

. While prokofiev's proposal may be slightly better for black, I still prefer white to extend rather than counter atari.

If white's intention is to play :w1:

in sente, white could have played it directly. It's pretty much sente anyway, because there isn't many big areas remaining on the board.

129 at 130 instead works for Black, so I'll be playing 128 somewhere else, probably at "a", "b", or "c". If "d" is a threat to kill the corner, I'll probably play that then "a", otherwise I'll probably just play "a".
