Ah, so black can't win that liberty race, even with a tenuki? Thanks, I didn't think of that, and if I had, I probably couldn't read it =). I'll have to keep my eyes out for that sort of thing.

Strategy and Thoughts

Well, I'm getting lucky here, that was another slack move by Black I think. If I'm wrong, I'll have to resign, so I've tried to read that out as well as I can, but this isn't a local L+D problem, it's a liberty race, and I'm at least one liberty ahead I think. Which means I can play to seal in, and ideally to kill outright.

Sealing in comes first though, because it works so powerfully with my thickness in the lower middle, and if I force him to live on the left in gote, that's fine be me. If he dies, I think I'd consider myself 90% caught up and the rest of the game should be possible to handle without some of the complicated overplays I had up my sleeve in the lower left and upper right.


Tactics and Variations

The key is to not respond directly to any of the hanes. Regardless of which one Black plays, White must respond with 66 below, and then connect out:

However, something like this I'm still very happy with, killing those stones and increasing my thickness further. We'll see what he does, I haven't read it out all that thoroughly as the key point was being able to tenuki the corner, but I feel confident that I'm 10 points better off again.


Fundamental Principles

In capturing races, always play the outside liberties of the opponent's group first, never start with shared liberties. 1 eye is a lot, especially near the edge when liberties can be created, so the reading for this corner was relatively simple. If Black tries to make his eye directly, I live locally and his group is still dead. Therefore he must reduce my liberties. The next move must be an eye-stealing tesuji, and then taking the liberties off the outside on the top edge. The rest is virtually unbranched.


Score and Counting

I wanted 1 point per 30 moves to catch up the game, and I should have 21 points by here (63 moves). I think it's more like 35+ after this latest move, and half way before the end of the fuseki is much better than I'd hoped, so it's all going well.

This way is a ko again. 3 liberties vs. 3+. (+ meaning ko). Black takes first when it gets that far (fill outside liberties before inside, esp. when the inside is a ko).

So I dunno. Maybe white just doesn't see this? Or he thinks he can do the ko in his favor? Or there's a variation that gives him an extra liberty and makes it work for him.

I just want to express, that topazg is doing an awesome job in these Malkovich Games. His explanations are well written, easy to understand and not overburdening with variations and thoughts.
Everything seems very clear and good structured. I hope, I can learn some structure for my own thoughts on my games from him =)

Really great, you must indeed be a good teacher!

Strategy and Thoughts

This is frustrating, I make another reading blunder. The two key points Black mustn't get both of are E18 (making an eye), and B19 (I will never be able to play A19 without dying in the corner due to liberties, and if he makes an internal eye I need to). For some reason, I had ignored the possibility of bE18 last move, and that would lead to a complicated internal seki. What's more annoying, is he's got it this way instead now.

However, luckily, move 64 may inadvertently save the day. It's only seki if his group on the left lives, and I think it might struggle to do so - if it dies, everything dies for Black and there is no seki.


Tactics and Variations

If he connects, he dies:

EDIT:

More Tactics and Variations

Originally I wanted to play E18, but of course, the reason it was one of Black's key points was that it created an eye. If I take it now, he gets both his eye and the key point at B19, so I simply must play B19:

I'm going to need to play "a" and "b" to kill the group if it has an internal eye, and that's going to a) take me two moves to get them, and b) mean my stones are already down to 3 liberties. Not only that, but his group at the top has outside liberties - this is deader than a very dead thing for White.

If it's so important, why didn't Black play it last move?

Because then Black's misses his first priority - that internal eye - his only way of getting it is to let me capture, which means he lost the important B19 point instead:

Maybe he sees something I don't. But I can't second guess myself like that. I still don't see a way for him to unconditionally live. If I get at least a ko out of it, I'll be happy. With that ladder I have plenty of ko threats.

I read, that - generally speaking - a ladder is not good as a Ko-threat, because you will reach a point, where the stones in the ladder and the resulting thickness out of the capture will be bigger than the actual Ko. So in the end, maybe you are going to lose more than you can win.

For topazg:
Please do post it. :) I'd like to see what you were thinking of.

topazg: sorry, still thinking.

Arg, so I did not see that white could just not defend and instead force me to lose some liberties. White is ahead in the capture race. And I don't see a way to force ko. Still, the sequence only cost me ko threats and essentially a wasted move. Not the end of the world.

Though the black group on the edge is now in a bit of trouble. Losing it, too, would really dent that 70 point reverse komi. I need to escape or things start looking grim.

For Marcus and other observers that want to see my overthinking craziness:

The top left

Ok, well, I assumed he'd connect to make his eye, leaving me with a ko I must capture. If he did, I wanted to take the time to remove a lot of the bad aji from the left group by sealing it in completely. Sadly, this gets awkward. If I don't, I can create a permanent seki due to shortage of liberties, which I can then use to attack that middle group - provided the aji isn't too severe, as follows:

This may initially look favourable, but Black's virtually ko monster, because all he has to do is keep running with that group on the left, and he's got at least 10 ko threats. I simply don't have many, and if he ignores one he turns it into about a 60 point direct ko in the corner with "a" or "b". Which means I'm in a lot of trouble - he's going to escape. What's worse, he has a liberty trick up his sleeve too, playable pretty early on:

Here, he manages to prevent me from getting "a" because of a shortage of liberties, which forces me to capture the laddered stones first, allowing him to play 79 inside, turning the whole thing into a horrible horrible direct ko. So, my response is to capture with 74 instead:

Here, if he fills the ko, I can play at "a" and return it to the two move approach ko, and it looks like the best I can do. However, more and more it looks like I can't kill outright, which is really annoying. Originally, I thought this double ko worked, but the shortage of liberties issue at the top means all it does is prevent the even more icky direct ko, but still doesn't fix things completely.

However, now I have an easier time of things - now, there's no real liberty race any more:

Even with the shortage of liberties play at the top, I'm still one ahead. I also don't have to worry about "a" creating the two stage ko on the left, because I can respond to it with "b" as it doesn't take away any of my liberties. So, what's the bad middle aji left? (see next hide tag)

If Black can't get out, this is the sensible way to sacrifice for thickness I think, and is some compensation for the loss. However, if Black tries to save everything, it's complicated:

"a" is now a working ladder for Black, and White can't play "b" without "c" causing a shortage of liberties. White wants to play "d", but again that doesn't affect the ladder. This just looks like an impossible task. What else can White do?

I think the hane here for White works. If Black "a", White "b", if Black "b", White "a". If Black "d", White "b", if Black "c", White can extend without dying. Something like:

That thickness is intolerable, and may give Black a really good top right. So instead I must respond, and we still have a funny double ladder thingy going on that I can't completely ignore (a-g):

There's just so many reasons I wanted to kill that aji on the left firmly! Maybe I should actually connect at E12 instead thinking about it. Bleh. Let's see how the game goes first ;)

Thanks topazg ... it's interesting to see how you think about the position. I have to admit, in situations like this I'm more likely to play like Magicwand (whatever feels best), only I don't quite have his intuition. :D
