Hi Mike,

I feel like I should disclose that I looked at the empty board for quite a while on this move.
3. We may not ever look at the game on a board. We may only visualize the board from moves written in text
Rule 3 was ambiguous about looking at an empty board. It's appropriate to let Telegraph know, so he can agree or disagree about looking at an empty board. Obviously, an empty board helps.

Good point. Thanks

I had a good look at the empty board diagram before. It felt a bit like cheating. Not sure if it's undermining the spirit of the game a little. Perhaps we should decide if that needs to be a rule?

Trigger accepted. W hane, B connect, and after W 14-5,
I play:
16-6
Q6

Oh and I haven't been looking at the empty board, but I don't mind if you do. I'll just include a note in my comment if it gets to that point for me.

9-7
J7

Hane over top.

Given that he made a comment before his move, I presume he was reading hard before playing this move. The good news is that he decided to start with a somewhat crude move first, where I don't have to think very hard. Also, I'm not sure that this is the right timing at all - his stones on the O-line are going to be liability to die quickly, as opposed to helping exploit my weaknesses in the center. I think coming out with O7 attachment first was called for.

When you get attached in the most valuable area, the only candidates are hane or extend in some direction. In this case, if I extend I'm going to be further weakening my large knight's on the left for no apparent reason - I should, at least at first, only consider hane over top or cutting with the hane underneath.

If I hane under, he will cut, and then I can capture his cutting stone with a ladder at J7. The problem is that he would then atari at 11-6 and connect at 11-5, and my shape would be horribly broken, and I'd have lost initiative on the right. Cutting is committing too hard to the left large knight's jump.

So it only took me about a minute to verify that hane is the only basic candidate and at least a very reasonable answer. If there were no AI to potentially prove me wrong, I'd just go ahead and say it's the best move without further analysis. Having easy good moves like this means that my position can certainly be no worse than it was last move, so I'll just wait for him to show me what his plan is, and start reading seriously then. I can't imagine a sequence where I'm going to wish I had responded to this attachment in some other way.

What will he do next? Maybe crosscut at K7 (10-7). I think I have a decent sequence planned out for that. If he pushes along at 8-6 then he's bumping his head into my large knight and making me look like a genius joseki-innovator, but if he tenuki's entirely then this was a bad exchange for W. Maybe he wants to clamp at 11-6? I should just be able to cut it. He might descend down at J5, in which case I'm probably going to kill him gently by securing my outside weaknesses. This is not the time to play heavy shapes. I think if I were white, I would crosscut at K7, it looks like the most promising use of this aji.

13-2
N2

Atari, and connection underneath.

Huh? He kicked? Why? Obviously, if I let him connect by playing tiger's mouth at 12-2 himself I'm going to have a bad time. So my only options are 13-2 to connect to my wall, 13-3 to make a weird defensive shape, and 12-2 to keep locally strong shape. If his move is a good move, I probably have to play 12-2 or he'll take advantage of my shape somehow.

The only reason he could have played this move is if he's looking for aji to play out a sequence somewhere else and wants a good exchange first. The key is to give him as little of use as possible here. I think he might be looking at the crosscut at 6-4, 7-4, 7-3, and trying to ensure himself life on the bottom? I think I'm just going to respond passively over there at the point, giving him a large corner in order to take the bottom strongly.

13-3 I can't really see a good reason for. It seems to just give him another nice forcing move by descending at 11-2, threatening again to play 13-2 to connect himself.

My first instinct was 13-2, but then the shape looked a little suspicious and I thought there might be some small trap. If he wedges, I atari, and he connects with an empty triangle, then I'd like to connect on top to help with the knight's move weakness. I thought at first that he would then play atari from his two stones at 13-3. I totally forgot that his two stones right now have barely any liberties, so that if he does such a thing, it's self atari. All he could do is double atari with 12-2, and when I connect, he'd be out of forcing moves. If he connects that back and hopes I respond, I certainly don't have to locally to maintain my capture of his first line stone. I'll note here that this is my first misread that I can say is almost certainly caused by not looking at the board

Overall, though, that's looking really promising for 13-2 over 12-2. If there's not immediate tactical reason not to, it will make me so much stronger in the potential fight at the center to connect while disconnecting. He needs some other order of moves to exploit my shape locally. Maybe the clamp again at 11-6? My plan was to play 11-5 cutting it, and it doesn't seem by my reading that this exchange will help him exploit that. The center crosscut seems to go much better when I don't have to worry so much about my 12-th line stones, because they're connected to my wall. I can't read anywhere he can take advantage, then, so I'm just going take my connection and claim a good exchange.

Next move I expect he will get to the point and define a shape for these middle stones somewhere. The white stones on the 14-th line are basically toast for him after my move, so I'm expecting something to do with my large knight on the left. I don't think there's anything that good to do there, so I think he's about to crash and burn. This has become a very difficult position for white.
