Thank you so much ❤

Can I set new network in stockfish for best performance ??

This network is by default in the android versions, if there is a network

If there is no network, then of course you need to use this version, it is the most relevant.

Thank brother

Which one is better default or new network ??

In your knowledge which is best default or new for cfish android ?

I do not like one thing. Stockfish doesnt accept other nnue, only default.

waldemar the nnue of stockfish is built in.. It depends how it is compiled, mostly built in nneu.. If u can find stockfish that no built-in nnue by default u can import other nnue.. Stockfish with built-in nnue at the moment.. Other nnue in stockfish test didn't passed, u can see a highlighted nnue color green, which is I believe strong.. If u can learn how to compile stockfish u can create ur own build, built-in nnue or not built in.. Hopefully this will help you 😁. Sorry my English not good. Okay 👍

Better code for hash table generation

This patch removes some magic numbers in TT bit management and introduce proper
constants in the code, to improve documentation and ease further modifications.

PV-Nodes likely to fail low

Do not decrease reduction at pv-nodes which are likely to fail low.

The idea of this patch can be described as following: during the search, if a node
on the principal variation was re-searched in non-pv search and this re-search got
a value which was much lower than alpha, then we can assume that this pv-node is
likely to fail low again, and we can reduce more aggressively at this node.

Distilled Maia Net

Download this instead of the previous nets as the past ones have issues with low evals. This one has more reasonable evaluations. Trained with 30m positions of the maia1900 leela network (self-play at 1 node).

About equal to ~2200 elo. When nodestime is set to 1, it's about ~1200 elo.

Best used with Cfish set to pure=yes.
