This is in mint shape. Just have to wipe off the wax powder on the sides. Won't be taking this to the laundromat but probably set it up at my girl's place. Alaskan Spruce. The wax gives it a super smooth feel on the sides and doesn't look like this has seen much use.

I encourage anyone who has wanted a traditional board like this to pull the plug--the market is good for these right now. It's really beautiful.

go news Shin Jin Seo defeats Byun Sangil 2-0 in the Lanke Cup finals

16 Upvotes

Shin is now only 1.5 rating points away from hitting 3900 rating according to goratings.
The first game was very shocking with Byun Sangil losing with 73% Katago correspondence rate to Shin's 79%.

The second game Byun Sangil had no chance after an early game mistake and that advantage persisted through the end of the game.
This marks his 10th (or 9th) major world championship title, passing Ke Jie.

Looking for DDK Lessons

5 Upvotes

I’ve been playing Go casually for about a year and have just joined a very small local club that meets once a week, but am just on a crazy losing streak. I want to get better because I enjoy it so much, and would love to find someone to take lessons with. I checked out OGS and a lot of the other sites and don’t think I necessarily need to spring $50/hr for a dan-level teacher (no offense, I’m simply not that good). Best I can figure is I’m around 15kyu and would appreciate any recommendations!

Can you recommend an app for online, free-form play with friends

5 Upvotes

I want to play unusual variants of Go with my friends (Atari Go, White to live, 3+ colors, Zen Go, Miai Go, Bannegi, etc), do tsumego together, etc.

Right now, I use Tabletop Simulator, because it's very straightforward to use. Make a lobby, load up a Go board, and join. Anyone can grab any stone of any color, move them around on the board as we please, and even recolor the stones. There are no systems in place, you are just playing with the assets, the way you'd do whatever you like with physical stones & board in person.

However, not all of my friends want to buy Tabletop Sim just for Go. And the Go board in Tabletop Sim is kind of low quality.

Most free websites are only designed for straightforward matches, with turns, codified rules, set board sizes, timers, and require an account.

Is there an existing app that does this better? It would have to support:

  • Online board with friends
  • Unrestricted placing & removing of stones by whoever
  • Free, or low-price

Even better if it supports:

  • Importing SGF files
  • More than 2 players in an instance
  • More than 2 colors of stones
  • Custom sizes + shapes of boards
  • Multiple boards in one instance

Any recommendations would be wonderful! (regardless if it has extra bells 'n' whistles, or not) Thank you <3

promotional Go now on Boardbattle.io

Hello,

We have recently added Go to our collection of games over at https://boardbattle.io/go, so it would be good if we could get some people to try it out and give us their thoughts, all feedback welcome! We currently only have a small (but growing!) player base, so if you can't find a game, DM me and I'll hop on for a game. We're eventually looking to run some small tournaments, but we only currently have enough regular players for Four in a Row tournaments, but it would be good if we could do the same for Go also!

Thanks!

joseki Why doesn't White atari with 3?

Post image
8 Upvotes

I'm reading Kato Masao's book on the Chinese opening, but I don't understand this joseki. The book says that White should save 1 for later because Black can kill with the a-b-c sequence if White doesn't protect the corner after 4, but I think White can preemptively remove the aji by playing 3 to the right of 2, atari, and then playing 5 at 3.

If I'm reading correctly, the extra atari allows White to extend to the right of 4 if Black tries a-b-c. If Black then ataris to the right of c, White captures next to 1 and Black can't play on 19-6 to prevent the second eye (without getting captured). If Black simply turns to the right of 4 before a-b-c, White plays c and lives.

So, why would White leave behind this aji? If Black's going to play 4 anyways, can't White get something out of it?

go.eiajus.lt: play on OGS and Dragon Go Server, 9 practice bots from 30k to pro, KataGo analysis in your browser, lessons and puzzles. Free, no account needed to start.

0 Upvotes

Here is a clean, polished version with all markdown formatting and extra symbols (like asterisks, extra colons, etc.) removed:

Hi r/baduk. I have been building a Go client that runs entirely in the browser (it installs as an app on phones too), and it is at the point where I would like more players on it:https://go.eiajus.lt

The idea: no new server, no new rating, no new community to rebuild. You play real people through your existing OGS account (live games, challenges, correspondence, spectating, friends) and turn-based games on Dragon Go Server. Everything else happens on your device.

What is in it:

  • Play people: OGS login, the OGS lobby with matchmaking and challenges, live games over the socket, correspondence, and spectate. DGS turn-based games in the same Lobby, with the waiting room and invitations.
  • Practice bots: 9 opponents on one rank scale, from a random 30k to a searched pro, and you can switch bot or strength mid-game. "Human-like" uses KataGo human-style network to play like a 20k, a 5k, a 2d... rather than a crippled engine. A "Pro" bot plays in the style of the professionals of a given year (1850 to 2023). Automatic handicap from the rank gap.
  • KataGo analysis in the browser: real KataGo networks running on WebAssembly in a worker. Nothing is uploaded, no queue, and no credits. Variations on the analysis board, moves judged by rank, saved reviews, SGF in and out.
  • Learn: 32 interactive lessons from the rules to dan-level ideas, where you play the moves on the board instead of reading about them.
  • Puzzles: 214 solver-checked puzzles from 30k to 2d, a puzzle rank that moves as you solve, spaced review of the ones you missed, a skill tree, and you can import your own SGF problem collections (they stay on your device).
  • Demo board: a game with all its variations as a tree, which you can show live on OGS so everyone with the link follows your moves.
  • Dark theme, stone sounds, works offline once loaded, no tracking of your games.

What it is not: there is no account system and no database. Progress, puzzles, and settings live on your device; games live on OGS or DGS. If you are looking for Fox or Tygem, this is not that (yet).

Videos:

It is free. If anything breaks or feels wrong, the Feedback button in the app goes straight to me, and I read every message. I am especially interested in hearing from people who play on phones and from DDK players trying the bots: are the ranks honest?

scoring question Question about points

Post image
12 Upvotes

I have a question about this exercise. The answer says that this move is worth 6 points, but I only count 4.

If white plays here, the group is obviously alive, made 1 capture and has 5 points of territory, so 6 points in total. If black plays here, it's a seki and the left part of the corner is neutral territory, but the two inside liberties on the right should be considered white territory isn't it ? So 2 points for white, and a difference in outcome of 4 points.

Am i wrong for considering the inside liberties of a group in seki as points ?

newbie question How many correspondos y'all got going at once?

7 Upvotes

Hello Reddit badukkists. I never used to play correspondence games, because someone told me it's not as good for you as live games, but life is busy, and I was having trouble finding time to sit at the computer. So I started a few correspondos on OGS.

Then I found out about "tournaments", which basically finds you a bunch of correspondence opponents at once, and now I have like 20 games. Is that too many?

How many y'all rock? 🤘

Game Review Request Full-rules Go with scoring and dead-stone estimation on a $10 touchscreen board, free and open source

9 Upvotes

I have been building a small handheld console on a cheap ESP32 touchscreen

board, and Go is one of the games on it. Posting here because Go on tiny

hardware is usually a toy, and I tried not to make one.

What is actually implemented: full rules including ko, suicide prevention and

passing; territory scoring with captures; and a dead-stone estimate at the end

so a game can be scored without the players adjudicating it by hand. The rules

and the scoring are plain C++ with no hardware dependencies, and they are

tested on a desktop rather than only on the board.

Two levels for the computer opponent. Two boards can also play each other over

Bluetooth with no pairing, the moves carried in a 31-byte advertisement.

I would genuinely value a strong player's view on where the rules or the

dead-stone estimate fall short. That is the part most likely to be wrong and

the code is right there.

It runs on a $10 to $15 board, flashes from a Chrome tab in about a minute,

and Go is one of 40 games on it. Free, GPL-3.0.

promotional ZBaduk - VR client

Thumbnail
gallery
14 Upvotes

If you don't know zBaduk, have a look at https://www.zbaduk.com . It's a website to do AI reviews, has been around since around ~2018. I must admit that in recent years ZBaduk development slowed down.

But since about half a year now, I've actually worked on a lot of different things again, and most of it remained hidden from public. I don't often find the time to actually post about what I am doing.

Now, for some time I considered to release a VR client of ZBaduk. And this evening, I released a demo of this. It comes in 2 versions:

If you just want to play stones on a board, (without any statistics, no katago), you can find a simple version here: https://deepz.io/vr

But the real project is on https://vr.zbaduk.com which has a list of saved games, allows you to play with a bot, and to review your game with projected statistics, and has a move tree. However, it requires a premium zbaduk account to actually get access to the GPU statistics.

Even though both websites are made for VR devices (recommended for Meta Quest 3), you can actually also use all of this on your desktop computer. But obviously, it's a 3d environment, made primarily for VR devices. If you just want to study go on desktop without fancyness: visit zbaduk.com

Enjoy!

Which pro players/games should I study

8 Upvotes

Hi everyone,

I'm around 7k on Fox and 10k on Pandanet. I'd like to start replaying pro games on a real board, guessing the pro's move before playing it, but I'm not sure where to start.

I am mostly interested in the fuseki up to middle game. My current level is 7k fox/10k pandanet.

Thanks !
