To use it on 64bit Windows immediately

Just download the all-in-one package (LizGoban-*_win_*.zip), unzip it, and double-click LizGoban *.exe. You do not need installation, configuration, additional downloads, and so on. Its file size is due to the built-in engine:

• KataGo 1.11.0 (eigen, eigenavx2, opencl) + 15 block network (g170e-b15c192-s1672 from KataGo 1.4.5)

You can switch KataGo versions (CPU, modern CPU, GPU) by [Preset] menu in LizGoban. The first run of the GPU version may take a long time (1 hour on a low-spec machine, for example) for its initial tuning.

To customize it on 64bit Windows

If you want to use other engines, network files, options, ...

1. Prepare engines (Leela Zero and/or KataGo) and their network files (aka. weights, models) by yourself, if necessary.
2. Download and unzip the same all-in-one package as above.
3. Copy sample/config.json to the same folder as LizGoban *.exe and edit it. See README for its format.

To use it on other platforms (Mac, Linux, ...) or Windows with more flexible configuration

Download the source code and see README.md.

LizGoban 0.7.0-pre4

• Tune the behavior of "AI persona".
• Officially support movesOwnership in KataGo 1.11.0.
• Add auto-adjustment for [SGF from Image].
• Add items to the pull down menu of AI strategy and delete the corresponding keyboard shortcuts "1" to "9" instead.
  • "pass": AI plays "pass" if there is room.
  • "swap n": AI swaps engines for black and white randomly with probability 10n%. (You need to set engines with different configurations, e.g. LZ38 and LZ157, for black and white beforehand from "Engine" menu or "Preset" menu.)
• Use change of ownership in addition to ownership itself for facial stones.
• (Remove 3n opening method for handicap games.)

If you are willing to help developments, please try new weak bots for matches vs. AI (work in progress). This is a step toward ideal bots that have a wide variety of playing styles and auto-adjusted strength without unnaturally stupid moves.

1. Click "File > Match vs. AI".
2. Click the pull down menu beside "vs." and select "persona".
3. Click the board to play a game.

You can play against bots with randomly generated characteristics from "..." button. You can also adjust "sanity" slider anytime, or check "auto" for auto-adjusting.

In addition, there is a new system of virtual opponent characters. When you input any name from "..." button, LizGoban generates a bot with the parameters based on its name. For example, "jowa" prefers to capture stones, "alex" likes positional plays, etc. Try various names to find your favorite opponents. Note that unreasonable strategies are still tough if you set high "sanity" because the moves are selected only in major suggestions by AI.

LizGoban 0.7.0-pre3

• Slightly improve ladder continuation.
• (Bonus) 3n opening method for handicap games in Tool > Experimental. This is just a temporary trial and will be removed in the next release. See #75.

solve tsumego pictures

• Add import of diagram images.

This is very low-tech. You may need parameter tuning or manual correction for photographic/reflective images and marked/numbered/glossy stones. But it is still usable for many tsumego pictures on the Internet and many YouTube screenshots. You can also try [Online version of "SGF from Image"].

• Fix minor bugs.
