Leela Zero + Sabaki had really transformed into a fantastic analyzing tool!


#1

When I discovered Leela Zero, it was eye opening. It’s not proprietary, it’s not charging any fee, and it’s mighty strong. It’s like Sai in Hikaru no Go only in that it does not teach, only tells you a cold number - winrate percentage.

But for a long time, there’s no good interface for analyzing games.

Lizzie was good but I always find it not quite user friendly. Like when I hover mouse over the best move, the variation appears but keeps changing and I have to pause the “pondering” for it to stabilize in there. And I cannot save the variation. And there’s no command line telling me what LZ is doing or thinking. And the move tree is always confusing as it appears to be not moving and I do not know which move I am at. etc etc.

I have been using Sabaki to write sgf and edit sgf and it’s been great. The navigation tree is very very clear. However it lacks realtime analysis like Lizzie so I have been using both… Until recently…

the most recent Leela zero release adds analysis features, like lz-genmove_analyze, and Thank You yichuanshen! the author of Sabaki responded very quickly and added a lot of useful tools into Sabaki. It suddenly become a much better analyzing tool together with Leela zero. It can show better moves just like Lizzie and it can save those variations. And it could save out all the edits, winrates, variations, etc onto a new sgf but the realtime analysis alone is good enough for all I wanted and needed.

It took him three releases to get the things he wanted 0.40.0 -> 0.40.1 -> 0.41.0 but he did so quickly and so wonderfully. I don’t know him and don’t know if he reads posts here but again Thank You!

I really think Leela Zero has helped me a lot and I am glad I discovered this combo. I strongly recommend trying them and kudos to both writers!

(BTW, I run the 192 weight against 157 weight today and both times 157 won as black. And it wins in the late mid game when 192 has blunders. My PC is relatively good with E7 64GB RAM and 1080 GTX. Very weird.)

Thanks for sharing @ksnqx. Are there specific instructions to get the right combo on Windows?

What I liked about Lizzie was how easy it was to install. And it always pulls the latest LZ version!

It may look intimidating first as there are all those -g -w -d -m parameters but what you really needed is to download Sabaki installation file - an exe - for windows x64, install it. Download Leela Zero - the exactly same folder called “leela zero” that appears in the latest Lizzie 0.6 release, so you could use that folder too. And in Sabaki manage engine section, write in the link to leelaz.exe and some initial settings like weight file, playout limits, time management etc, and that’s it. It’s actually pretty fun looking into all the parameters and know what they do exactly.

FYI, I just found this:
https://deepleela.com/

“Review SGF” option there allows us to get heatmap and winrate without installing anything.
