This game has been adjourned. We'll hopefully continue in the autumn.

Okay, I'm back to continue what may turn out to be the longest Malkovich game... ever. But it survived a server move, I can't let a little thing like life stand in the way of its completion. Go has taken a bit of a detour in my life recently. I'm still playing through games on Dragon, but at a pretty slow pace. Malkovich moves are a little more costly to make than a move made with the same consideration on Dragon. :P

I will be moving everynight until the game is done.

That being said, this first move back will have no commentary from me except this open comment... Anything else I look at gets me cut up into ribbons (starting with O9 directly or something else disruptive like O10 for white) or doesn't affect white in any interesting way. If anyone asks I will enumerate the ways in further moves! I'll count again when this fight is over, and as always continue to read out some of the more worrisome spots on the board.

Hmm, I see some improvements to the forum, I will look around, but is anyone using the eido-go plugin to show their Malkovich "thinking"?

Anyway, the move ...

It is nice to see sumiyaka return, but... When I looked at the board, I first noticed I had forgotten everything about this game. Now things are returning slowly to my mind, and I see I have to do a lot of reading and judging (I decided not to cheat by looking my old thoughts :) ).

But that means I'll not be able to move today. I hope I'll be able to do that tomorrow.

No hurry, but I'll post to keep in the habit ;)

My suggestion for your move... you put down a stone, I put down a stone, and we both try to kill each other like civilized people... ( Yes, I've watched too much Princess Bride in my lifetime )

OK. So, perhaps I will not read very deeply now, anyway.

The point is - I may be a bit behind in area. But the white group on the right side will live. And the top corner is white. Black group on the top side is weak, but white cannot attack, because of the weakness of the top white group. So it needs reinforcement. Now - the moves

"A" tries to connect the running groups, but does not actually succeed, methinks. It also tries to seal black in, and does not totally succeed. But it should strengthen the top white group, together with the earlier forcing move.

"B" is a move that threatens to cut black in two. White gets something out of it, so there might be not so many points for black there as it first looks like:

"C" is one start of an attack towards the black group on the top. That would need a stronger white group on the top, and further consideration: should white seal black in or set black running.

Due to the white stones on the centre, white can probably reduce black on the lower left side pretty well.

So, this move first, then let's see what black will start, as this fight comes to a pause.

Fight is over for the most part, my opponent chose to keep the top protected with his move, and my groups are safe. There is potential for me to get some points in the small pocket around q11. I think if black plays r11 about 8 points are made in gote. I think white can take away 4 points in sente with a similar move. Since its only worth 4 points to me either way, I'm not going to play there now.

My count

Black:
(provided its safe) lower right about 6
upper right 17 ( includes the 4 point "pocket" I mentioned above.
N17 group I will grant 8
lower left 9
and my side will grant 5

Total 45 (unless I added wrong) [ and has sente -- or is at least taking it rightly or wrongly ]

White:
upper left 22
Q17 group (top to bottom) group 14
Q3 group 6
komi 6.5

White 48.5

Seems like a close game.

The question becomes how many points can either side make in the F7 area. White has a bit strength in the middle. There is also the move of C12 to consider. Both sides benefit a lot by it, but its gote for black, sente for white.

My moves to consider:

Both moves are gote. I like 'a' a little better because it makes the fight during the inevitable invasion a little more in black's favor, and seems to "secure" the same amount of points as 'b'. It also makes white's potential side extension gote. It also helps cast a shadow over the area of the board that holds the most unclaimed dots.

This 3 threatens to cut the black stones, so even if black ataris first, black needs to come back, and choose, to give the stones or to risk a tradeoff with the white stones on the top.

The nasty thing on the white's viewpoint is that the last black move also helps the black group on the top. I think reducing the black framework is the most urgent thing to do, anyway.

I even considered invasion:

After this, black no longer has good prospects for expanding towards the top left corner, but on the other hand, the white group on the lower middle becomes a bit weak :(

My opponent is playing like he is way ahead. Perhaps I should revisit my counting, or the status of the corner ;) In any event, I don't think this is deep enough -- if my counting was correct. However, if my counting is incorrect and white is way ahead, this is an excellent approach.

This allows me to double the amount of points I count this side, and attack the white stone. The center has two areas to push on, and C13 is still a large move for black.

I'm not sure where white will go next. Maybe attach to my stone?

OK. First this big point, then I can try reducing the side a bit more, or attacking the top group. Black has initiative again, let's see how he uses it.

I chose here instead of point 'a' because I don't think I can contain
the white stone easily. And it becomes an all or nothing scenario.

Doing this, especially option two, should allow me to abandon the
stones and use them from the outside if needed. Or I could keep
extending my group and white needs to think about connecting.

Plus it just feels unexpected, and not completely stupid -- maybe just a little ;)

I think gain white got on the side and my gain on the side keep the
score roughly the
same as the last time I counted.

This move felt pretty weird, so I had to take a break and look around.

Black simply comes too far, and I can cut:

Because I was worried about the cut. But I did not like that, it feels it forces black to strengthen the corner more.

But this allows black to squeze and secure the side in sente. So it must be dismissed.

And, as I thought before; this should still work :scratch:

Continuing cut first think later


The following sequence looks not so good. So there must be a something else. I'll jump out and give myself some more fighting options. Perhaps something like below will be workable in the future. Or I die. Either way, its all good.

Ah. Naturally. This did not come to my mind. As I thought in the previous move, the connection on the lower side is weakish, and depends on the lack of liberties on the black group. This move adds those liberties while threatening to weaken the white group on the left of it. I need to strengthen the white stones there while keeping the white stones on the side safe.
