Re: Winboard.debug file missing.

Oh and also why Stockfish does not use syzygy tablebases in Winboard with this command? :cry:
"stockfishx64-modern.exe" -fd "C:\Program Files (x86)\WinBoard-AA\WinBoard\WinBoard\Stockfish" -fUCI -firstOptions "SyzygyPath=E:\syzygy"

Winboard.debug file missing.

I use the Winboard 4.9.191026 and as it seems i'm not able to create a Winboard.debug file! I try to put -debug in engine options e.g bihasa32.exe -debug /fd="C:\Program Files (x86)\WinBoard-AA\WinBoard\WinBoard\Bihasa32" /variant="gothic" as also in "Additional Options" in the start with /debug as ...

7-piece available in let's check, just not fully implemented. A winning position for white show up as "+1" and winning for black "-1".
Are you sure?
Try this:
[d] 8/2k5/3b4/7R/1P2n3/2P5/8/2K5 w - - 0 1

I get with "let's check":
Rh4 0.00
Rh3 0.00
Rh2 0.00

while white is winning with Kc2 or Kb2.

I'm considering another ASUS Rog RTX 2080 Super for black friday. How much gain can i expect over single 2080 Super?
Enhanced Leela performance.
About 20-30 % plus.
Much more. I think 85 % to 95 % is to be expected.

Can somebody show me how to find the 7 pieces with Lets Check?
I asked and they said the feature is not yet implemented.
Go figure :D
But they said very soon will be added via an update.

Re: NN Engine GPU Usage

OK, switching Leela to Multiplexing, since I have two GPUs, and 4 CPUs, but leaving BackendOptions blank, since it crashes when the recommended data is entered (see my other post) I now have Task Manager open exactly as you advised. Leaving backendoptions blank can never lead to a good end. :D And ...

Re: NN Engine GPU Usage

Hello All, I just purchased a new PC with dual NVIDIA GeForce RTX 2080 TI GPUs in order to maximize NN engine performance. However, when running Leela (Fritz 17 version) in Fritz GUI, Task Manager shows only 15%-16% GPU usage. Switching to Fat Fritz, the GPU usage drops to 12%. Is this normal or do...

Re: NNs seem to solve the Gusev Qxe5!! easily.

i have no access to a relevant analysis by any NN because i dont use a seperate grafics-card...imo its pretty easy to make (queen)-sacs without having "-9" in your head ;-) If you don't have the Q=+9 in your head and go for a sac, then you will end up making in more than 99.99% of cases a blunder t...

Re: Fat Fritz destroyed Stockfish!

Hello I have FatFritz but what is "FatFritz_v266" is that a newer version of the weights? If yes, where can I find it? Yes i think it's an updated one from the release of Chessbase. Albert gave it to me. I guess it will be in the official update of Fritz 17 in some weeks. In fact i think Albert sai...

Re: "The supervised learning brought little even style wise."
my impression is that fat fritz is clearly better than the average nn tactically and worse positionally.

I have no idea how this translates to games
My impression from seeing some 120+ games of Fat Fritz is exactly the same!!
