Stockfish - UCI chess engine, compiled by Stéphane Nicolet Rating JCER=3151 Timestamp: 1614365129 Introduce DistanceFromPV We introduce a metric for each internal node in search, called DistanceFromPV. This distance indicated how far the current node is from the principal variation. We then use this distance to search the nodes which are close to the PV a little deeper (up to 4 plies deeper than the PV): this improves the quality of the search at these nodes and bring better updates for the PV during search.

New chess engine: Fisherov 0.97 NNUE

Image
  Fisherov - UCI chess engine (NNUE) Rating JCER = 3169 (3 place) Fisherov is a chess engine derived from Stockfish. Code has been added in various parts to achieve a different style, which becomes more evident by deactivating his neural networks (although this would cause him to significantly lose his strength but he would gain in aggressiveness, which would be interesting for human training or to make him compete against other non-neural chess engines). For greater robustness and competitiveness, the use of a neural network must be left activated (as it already comes by default). The engine already has a network incorporated, although there is also the possibility of using another network from the UCI options. This engine was developed by Luis Damián Primo and Andres Ivan Primo residents of the province of Córdoba, Argentina.  Fisherov 0.97 download  -  Engine is not publicly available and is non-commercial "Due to a request from the Stockfish team in doubt about compliance wi

Chess engine: Lc0 0.27.0 (Windows and Android)

Image
Starting with this release, we are distributing two packages for windows with Nvidia GPUs: the cuda package and the cudnn package. The cudnn package is what we used to distribute so far (but we called it cuda), and comes with the same versions of cuda and cudnn dlls we were using for the last few months. The new cuda package comes with cuda 11.1 dlls and requires at least version 456.38 of the windows Nvidia drivers, and should give better performance on RTX cards and in particular the new RTX 30XX cards. Notes: The cudnn package will work as-is in existing setups, but for the cuda package you may have to replace cudnn with cuda (or cuda-auto or cuda-fp16) as a backend (if specified) - this will certainly be necessary for multi-gpu setups. Some testing indicates that cuda 11.1 may be slower for GTX 10XX cards, so owners of older cards may want to stay with the cudnn package. If your testing shows otherwise do let us know.
