Second, the winrate plot is super useful, but as I play through my game, sometimes the top choices are not shown. Is this a bug? Did I not let it analyze long enough? (sorry if this info is right in front of my eyes)


I must admit that this point isn't entirely clear for us.

Perhaps this answers your question:

The chart is a plot of the winning percentage (always from black's perspective) according to LeeLa Zero.
The Y-axis shows the winrate, and the X-axis shows the move number.

Each node in the tree however could have 0, 1 or multiple proposed moves by LeeLa Zero, which one is used to draw the chart ? LeeLa Zero will prefer to play the variation with most playouts. For that reason, that is also the move for which the winrate will be shown in the chart.

Well, what if there are branches ? For which of the selected nodes does ZBaduk plot the winrate?
Zbaduk always shows the winrate of the TOP branch. (the main/first line of play).
That means, if there are multiple moves played out not all of them will be plotted as charts.
The variations (branching) will not be displayed at all, only the main line.

Well, that's not entirely true. On top of that also the selected node will be displayed.
So, when you move through a variation which is not the main line, then also that variation will be plotted in the chart as a yellow color, but only for the selected node and the path that leads to it. At that point 2 lines will be plotted, the black line is still the main line, and the yellow line represents the selected variation. So, that you can see visually in the chart whether this is an improvement to the main line or not.

I use this chart especially to quickly detect where the game was decided (i.e. a big fluctuation of the winrate).

The moves which are actually shown on top of the goban, are the ones which are also shown in the table with stats.
The winrate and playouts is displayed on the board. But the colors (green, yellow, red) indicate which move has most playouts.
Again, because that would be the choice of LeeLa Zero.

I hope this helps, but please ask away if there are more questions.

ZBaduk now support LeeLa Zero version 0.17.
I also updated the weights to the most current "best network".

Just installed an update which should result in a more fluent experience for the "Analyze full game" button.

Enjoy.

How do I stop zooming-in the moves when I'm on laptop?

@johnsmith sorry for the inconveniences of this.
ZBaduk switches to a kind of "mobile" mode based on the resolution of your computer and the size of the goban.
It is real convenient for mobile phones, but it can be annoying for laptops.

A better way would be to look at the "user agent" of your webbrowser.
And that's exactly what we will do in the next release.
I promise you that I will make this a priority for our next build.

As for now, an easy workaround is to use the zoom-features of your webbrowser.
i.e. if you put your webbrowser in 80% zoom that could be enough.
For most webbrowsers the zoom can be altered with key combination: "Ctrl +/-"

I hope this helps.

(PS: In mean time, I added this information to the manual as well)

Just installed a new version with lots of small changes:

There's been a lot of discussion in LZ forums about the definition of "the best move". Apparently many tools (and so did ZBaduk) just take the move with the highest playouts. But actually that's not entirely correct. LeeLa Zero actually sends us an "order" property which should be closer to the truth. To determine this "order", it will often rely on the "LCB" winrate.

So, from now on, our statistics table will be ordered by that "order", and we added and renamed the columns as well.
    Intuition = the output of the policy network. (new column)
    Playouts = used to be "visits" (renamed)
    Winrate = winrate (no changes here)
    Decision = the LCB value (new column)

While going through this we added several small performance tweaks, bug fixes, reconnection improvements which will surely make a difference if you have a weak wifi signal on your phone,

Added just a little transparency to the numbered stones, in case you select a sequence in the stats table. Which makes it a little more beautiful.

For @johnsmith better resizing/autozoom decisions: takes your useragent in account in its choice.

Added contact info on several pages.

And a lot more ...

Enjoy ! :)
