Re: 1.g4 opening is losing?

It's funny to see what's going on here.

I only wanted to mention I have 1.g4 down to -1.11 with LC0.
It's a draw.
And I have completely other variations.

Re: Lc0 node count and playing strength

With Stockfish or similar CPU engines it is easy to see how "deep" an engine has calculated, either by looking at the search depth or by looking at the total nodes calculated. In practice the search depth is the better indicator as the number is nicer and makes more sense for humans. One could day ...

Re: 83 nice Testpositions (Long and big post).

Interesting.
Maybe because I have a higher starting depth, due to 2x GPUs?

I have done a second run and it started with Rxf7.
I was waiting 1:41 minutes and nothing changed.

I have done a third run.
From 0 to 25 seconds Rxf7 was the move.
From 26 to 1:13 Nd6.
From 1:14 to the end Rxf7 was the move.

Re: 7 Man Syzygy and SSD

Use some 7-man syzygy with the SmallFish Chess for Stockfish app.

If someone has Cfish 11 or Asmfish 11 ready, please sent it to the SmallFish developer, he is waiting.

Re: 83 nice Testpositions (Long and big post).

Maybe you are using the wrong net or your GPUs are to weak. Running on my pc it doesn't switched and I have let it run up to depth 25. I'm sure it doesn't switched up to depth 21 and later to switch to Nd6 and back to Rxf7 doesn't make sense, because Nd6 needs to have better evaluation than +2.09, ...
