Changes in Arasan 23.1:
1) Disable book when running the "bench" command. Ensure tablebases and NNUE are initialized before it runs.
2) Support SIMD on older Intel/AMD chips. Default builds now assume at least SSE2 is available.
3) Fix #34 - specify C++17 for clang.
4) Various fixes to selfplay utility
5) New network, based on reinforcement learning from 280m positions
6) Singular extension changes. Allow some pre-search pruning during a singular search.
7) Some code cleanup and refactoring.
8) Fixes and cleanup to Makefiles, VC++ projects and CMakeLists.txt.
9) Output error messages related to intialization to stdout not stderr, and use the appropriate prefix (e.g. "info" for UCI).

Test run against 23.0.1, 2:0+1 time control:
5 141 551 276 27
2000 games, score: 54.48%%
ELO: 31.18 +-7.8 (95%)
LOS: 100.0%
Thank you! :)

Best regards, Alex

Hi Jon, that's not a quite healthy place for announcing your release ;-)

Thank you again Jon, your contribute is very appreciated and I add right now all the infos also in Promising 3000+ engines since it isn't a Stockfish derivative (I use your engine since much time before SF was released :wink: , together with Dr. Robert M. Hyatt's Crafty and other chess myths , so you are a CONFIRMATION of programming quality, not a promise :P )

Redfish is a very strong Stockfish MCTS derivative by Bookmaker ELO 3700 (USA)

(While Bluefish NN forum3/viewtopic.php?f=2&t=78112&start=20#p907430 is a Stockfish NN version,
so there are a blue and a red option like in Matrix, and it isn't based on MikeB's Bluefish 13.1a)

Stop using server resources to post chess engines that everyone is aware of.
