Neat game. The early-mid game where you keep leapfrogging all over the middle was pretty incomprehensible to me. I love your terror of ko fights.

Here's my guess as to what's going on (I didn't bother to read it out): It's sente when it's played (g1 followup), and forces White to play additional teire (reinforcing moves inside his territory) when dame are filled.

It's an endgame thing. Depending on how White answers it, Black will have some small sente moves against that group later. It's a little too subtle for me to understand exactly how much it gains, but it's a point or so.

I think when White answers this way it makes F1 sente later, for instance (or would have, if White hadn't ended up connecting underneath), while if he answered any other way, then L1 would be sente immediately.

Strong bots are weird because, when you're winning, they'll start playing in your territory trying to create weaknesses when there are none. Oh, that cut point looks dodgy! No, no it isn't. I could only find a 3d 9x9 bot right now because there were no 19x19, and unsuprisingly, I lost by exactly komi.

I would expects bots touted as 3d+ to realise how something just does not work. As in even an 18k can realise it does not work.

The way Go AI typically work is using something called a Monte Carlo simulation, which basically means they play out a large number of possible games from the current board state and then choose whichever next move leads to the best chance of winning. There are often times where the only way to really win is if your opponent makes a large mistake, which is when the pointless invasions that can be stopped by a DDK start happening.

AI doesn't think like humans, so while you might look at an invasion and use whatever heuristics to realize it will not work, the AI doesn't do that. There is a fundamentally different decision making process going on.

Today I learned the reason to o6 instead of o5 is that W q6 makes good shape.

Where should Black play now?

Bizarro Buddha
Feb 11, 2007
Ideas from a DDK:

Since W is pretty strong on the right maybe B should be worried about the aji at F3?
Other than that I'd be worried about W playing on the right to make B small, so maybe something like R9 so as not to get sealed in.
5 threatened to take the corner and 6 said "ok then" so maybe B should play R2 and R4 to take the corner and be solid.

No idea whatsoever but probably Q2, S2, O2. Who knows probably F4, its another problem that nobody knows the answer too cause its too vague. gently caress go

If you're going to play locally, R8 is probably better than R9 as it discourages the Q6 attachment to make shape - in response, Black can then bulge at Q7 and make a powerful shape himself.

Kosumi at Q7 is also an option.

But probably you just tenuki most of the time. The Black group is already alive and doesn't need an extension.

Seconding that. There's not much profit in it for white to mess with that black group - he can do something in sente, or he can do something worth a few points, but at this stage of the game he can't do both. Odds are it will sit until late midgame, if white finds that pushing the black group further into the corner has some added value in another fight.

But by that logic we should open at 3-3 and then just make a series of two space jumps along the third line for as long as our opponent lets us.

I like R4 becauce I would either Q3 if white played a stone above, or I would Q5 if my opponent played Q3. My moves are probably actually super bad though.

R4-Q3-Q5 is gote and strengthens White as much as it does you. Admittedly, you get pretty nice shape, but you also fix White's weakness at P2.

It can be worth losing sente to fix your weaknesses if you're aiming at weaknesses in your opponent's position in the process... but if you're going to play moves that fix both your shapes, they'd better be sente, otherwise you're just doing your opponent favors.

EDIT: Actually, in posting this, I realize that if you want to continue locally, playing P2 immediately, as a probe, is not the worst idea in the world.

What do you mean punishing? What's wrong with it? Black gets a wall, you get profit, and your approach stone is left as aji.

I think e3 is overplay by black, he has to extend and you get into standard joseki. http://eidogo.com/#ytTRXxAV

E3 is an overplay - if white replies with B3, then black is boned. If he connects at E4, white connects underneath to his pincer stone and B's direction is wrong. If black plays B4 to cut white off from the black stone, white can cut at E4 and black loses one of the groups. Try it and see if you can figure it out, e5 is one of the Great Classic Overplays.

Black's pincer itself isn't really something you can punish, but E3 absolutely is.

You're right, punishing is way too optimistic. What I wanted to know is how to best use the good aji from the stone on the outside. I just feel like there should be a way to push black into overconcentrating while building something at the top.

That's not what aji means or how it works.

Aji is by definition something you aim at later, not something you try to leverage immediately.

EDIT: Here, look at this. Obviously the moves on the right side are not to be taken literally, but as a visual "..." to show you that stuff is going on elsewhere before we come back to the position.
