Game 70 (7 komi, NZ rules) features an uncharacteristic large drop in winrate after move 159, and suddenly black is at least 8 points ahead. https://online-go.com/review/761790

In game 71 (7 komi, NZ rules), after 151. T2, white is ahead by at least six points. Black ends up dying on a massive scale and loses by 80 points. https://online-go.com/review/762760

In game 72 (7 komi, NZ rules) the entire sequence from move 46 - 82 felt like a giant "joseki on the side" (most of it playing out just the way Kata read it out at the beginning) with black getting a 36-point corner, whereas white makes a 12-point territory with thickness on the outside. https://online-go.com/review/764480

Re: My hand-crafted KataGo (+ AlphaGo Teach) self-play games

Post by Maharani »

Non-19-x-19 square boards are finally accessible on https://www.baduk.com/next/. I've played a 9 x 9 game in one go (about three hours) and am happy enough for this to be my only 9 x 9 high playout game (100,000 - 1,400,000 per move). From move 0 - 38, there wasn't a single move at which KataGo's second-favourite choice was close enough to its favourite move to qualify for my branching criteria. At move 39, we're already in the endgame with everything settled. https://online-go.com/review/767012

I've played three 13 x 13 games (all in the same file). The second game turned out a bit more complicated and exciting than the first one (30 moves longer, too). For a while it looked like a white win was in the cards. Move 53 was the highlight for this 10 kyu :D In the end, all three games ended as draws. Shoutout to game 3, move 66 as well. https://online-go.com/review/767121

Re: My hand-crafted KataGo (+ AlphaGo Teach) self-play games

Post by Maharani »

I asked high-playout KataGo to play two games from the Tibetan starting position on a 17 x 17 board. I still used NZ rules and 7 komi.

White won the first game, but the second (bottom variation in the same file) was a breathtaking draw. Here is my 10 kyu interpretation:

Moves 13 - 48 are an exciting early middle game.
Moves 49 - 69 black builds a ko factory.
Moves 70 - 90 white builds a ko factory of its own.
Moves 145 - 247 is the ko fight.

And Clydevil (~2d)'s interpretation:

49-69 for black is just a way to invade the white framework. You just have to see the whole maneuver as invading the whole top left. it's common when invading framework to play at several places and key points at the same time and deciding at some point what to sacrifice and what to make live. Here black discards the left and stabilizes the top part.
70-73 can be seen as probing exchanges, white makes black decide how he will kill it, thus deciding forcing moves in the vicinity.
74-75 can be seen as a first use of this white aji built in sente, white plays at the top 74, removing pbs in its shape and preparing an attack on the top group, black needs to answer to avoid things around K6 or H6 that could be large white reductions. So I guess here that white is just happy with 70-75 to play 74 in some kind of sente.
76-87 tries to recycle the white death into something useful, and it seems that what is mainly accomplished here is white huge yose at M2 followed by N2 (which is hard to see because in the game white changes it's mind and do not play N2, but locally white N2 instead of the game move 92 would be logical).

I also asked high-playout KataGo to play two games from the sunjang starting position (still with NZ rules and 7 komi). Black won the first game, the second (bottom variation in the same file) was a draw. Kata really likes the 6-2 point in these games. She played it once in the first game, twice in the second. https://online-go.com/review/818991

Game 77 (7 komi, NZ rules) sees some of the most bizarre endgame I've ever seen. White seems to play meaningless moves in black's territory from 154 - 175, then from 195 - 222 black seems to be returning the favour. After move 213, black is at least 2 points ahead. At move 248, white starts giving away points and ends up losing by 12. https://online-go.com/demo/view/880171

In game 78 (7 komi, NZ rules), black tries to build a center moyo. After move 43, white seems firmly ahead by 1 point and maintains a small lead throughout the game. There is a cool endgame trade in which white sacrifices its right-side group for a large bottom side. https://online-go.com/demo/view/884311
