Thanks mate!

I've just tried it and it works. But do you know why it needs LeelaGTP to run?

P.S. How strong is this Zen? Is it the same version as ZenithGo 6? 11.4?

The engine is basically 11.4 with several optimisations, so it is slightly stronger. One of those optimisations is that it also considers Leela's value network winrate, which is why it needs LeelaGTP to run.

Does this work without a license key for Zen? If so, this should be considered a copyright violation.

Does this Zen version use area scoring, like Leela?

I hope to buy the newest Zen version for my pc:
Amd threadripper(16 cores) and 2x nvidia geforce gtx 1080 ti 11gb.

Does it make sense to buy 2 more gpus?
How big would be the strength increase?

No one knows the hardware support detail of the upcoming version but according to Computer Go Server, Zen never test with 2 or more GPU (0g or not mention g = no GPU, 1g = 1 GPU)
But are you sure that Zen support 16 cores? We all know that Zenith Go 5 support up to 8 cores (from AlphaGo paper), I don't own Zenith Go 6 personally so I'm not sure if it support more than 8 or not. In buying CPU, I might go with 8 cores or 10 cores that have higher frequency.

Is there somebody in touch with Zen's author(s) here?

Because let's face it, as Satorian mentioned it, if this is really Zen, then this is probably a copyright violation.
But on the other hand, it may very well not be Zen, considering the very small size of the *.exe

As for myself, I would be really happy to add support for Zen into my game review program.

Yes, it might be violation, Hideki mentioned in some KGS game chat that he didn't know about it, but... it is not pure Zen, it's more like a mix of Zen and Leela (which is weaker than Leela itself).

Imagine this scenario: Zen is thinking what to play next:
D15 (MC: 65.5%)
D14 (MC: 64.0%)
D13 (MC: 63.7%)
...but then Leela comes in and says "hey wait, I have different opinion" and shares its opinion:
D15 (VN: 55.5%)
D14 (VN: 75.0%)
D13 (VN: 60.7%)
Now, two of those merge together to form a third evalution, which is actually some kind of average... Then this mixed program plays the highest value, which is D14 is this case. That's how I see it :)
