Chess Engines Diary

Dara opening book series is prepared by the user named "Alisyadara". Book - BIN format ( Used by chess GUIs Arena, Banksia and Droidfish) Binary books have some important advantages, especially for computer chess engines: space-efficient, fast on accessing and searching, more useful information.  At the most simple form, they are just a conversion of above text-opening books into binary, in the ready form for software and save text-binary converting steps. However, the major number of top books is built and worked with hash values from transpositions. Often each position is stored as a hash value (8 bytes) and some extra information such as the number of times occurred, number of games won by white/black / drawn with this position, average/maximum Elo of players playing to this opening position, chess program's success with the position. To save space those extra information typically about 2-8 bytes.  Dara 141024 (bin) download

While we usually focus on testing the most powerful chess engines, we occasionally evaluate amateur engines as well. This was the case in a recent tournament where the Sapling 1.1.1 engine emerged victorious. Since then, multiple new versions of Sapling have been released, with the latest being version 1.2.1.

  Sapling , a  strong dotnet UCI Chess engine [BETA].  Author: Tim Jones Sapling is still in active development so expect certain features to be missing or experimental. Also the current release is using a NNUE net trained from self play starting with random weights and is only 13 iterations deep, expect the engine to be much stronger in the coming days as the training does takes a while. Requirements - Sapling makes use of hardware intrinsics to improve performance. Currently your CPU must support: `Avx2`, `Bmi1`, `Bmi2`, `Popcnt`, `Sse`. Most modern hardware shipped after 2013 should be supported. - The releases come with a bundled version of the dotnet runtime, however if you want to run from source you'll need the dotnet 8 SDK installed. v.1.2.1: -> New network trained on 1.6bn positions -> Supports Chess 960 Sapling 1.2.1 download     for MacOS
