In this game, I am unbeatable. The reason?

Isaac Asimov wrote:A robot may not injure a human being, or, through inaction, allow a human being to come to harm.

Obviously, any hide tags in this game, on my side, are only to condense information. If my comments are short-ish, I'll refrain from hiding. Here, playing normally to see how things go. I'll allow cross fuseki, on a whim. Also, if my fiery opponent has an opening book, it seems in my best interest to play the most uncommon reasonable opening I can. I'm sure the bot will have plenty of pre-recorded cross fusekis, but one step at a time. It's not worth playing 5-2 just to confuse it... though I did adopt 6-4 openings for a while, at club...

doesn't your bot have debugging info (like gnugo) to see what other moves it considers/values.

gnugo expected white to play C16 (or would have played it itself), but in response to white's Q16, it plays the same move as Fuego, C4 (but when I run it multiple times, each time it seems to randomly choose a different move, usually D4 now, but once it picked D17)

Here, I strongly considered C15, because it gives me a great followup (the enclosure) if black played anywhere else. However, on consideration, I couldn't figure out the best way to make it work for me if black played C17 or D17, so I'm going to stick with straightforward and basic. Weird moves are well and good, but only if you're sure you know why you're making them.

@xed_over: yes, it has the ability to print move values & sequences and such. But it doesn't start doing any evaluations until we hit a move it doesn't know. Don't worry though, we're almost out of the book, I think this is the last trigger in this line:

Hmmm, this one threw me for a loop. I'd seen everything up to this shoulder hit. I almost played counter to the 'when shoulder-hit, play up or sideways' rule of thumb, by jumping to K3. However, I turned that down when I thought about how black could just play on top and lean on my stones to further expand the left side. So I'll stand up first to limit that a bit, and see how it goes. I'm used to playing Kobayashi, not having it played against me, so his shapes look better to me than mine do. I want to claim K17 as soon as possible, so I'd love to get sente out of this...

First move with actual thinking! I'm excited! (also komi is 6.5, correct?)

Unhidden:

I gave Fuego 30 mins for this. It believes its win probability is 0.494, so it actually feels slightly behind at this point, but very slightly.

Here's the full sequence Fuego predicts (only hidden for brevity):

This is a long sequence, and I wouldn't put too much stock in it, esp. after the first few moves. I do think the W2 it predicts is interesting, I doubt Chew (or I) would play this move, but I actually like the idea of it: a very loose multi-purpose move, threatening to make a base on the bottom, and also making the right side more urgent (white 4 is a followup that stresses the right stone). About E5 itself, there isn't much to say, I think it's solid. At the beginning it was favoring this sequence:

But it decided on the more solid play instead of the double hane.

Out of curiosity, fuego proabably has some routines to select the next move at least.
Do you know how far they go and how many "rule based candidate" it is considering ?
meaning, did it just select n candidate and evaluate them directly or does its rule engine also construct a few W answers move before turning to MC evaluation of each ?

It's bad that I feel like I'm already behind, but we'll see how long it lasts. It is urgent to get a base for those two stones, so here it is. I would've loved to approach the bottom right, but I feel like almost any approach would get pincered immediately. Better to not approach at all than to let both sides get split. After this, my stones will be stable enough that I can tenuki, even if black denies me that extension. Or I can take the extension and be developing almost as fast as black.

Mnem: I don't like that move for the same reason I didn't jump three spaces: if black takes F4 or G5, its wall is formidable, and I'm only getting third-line territory. Additionally, with that move, I don't even get assured the corner (because of bB2). Because the left side is biggest in the current equation, I did the move that has the most impact on that region.

Mnemonic's suggested move is (to my knowledge) a very common move when faced with the Kobayashi Fuseki.

Hidden because it discusses Kobayashi strategy, may have an impact on Chew's thoughts:

@Chew

You should not get to be unhappy with Kobayashi continuations after responding at F16. It (or a delayed Chinese or something) is (as you well know) expected after black :b2:

and

.
The one space low pincer is a good alternative, if you weren't sure.
