Chess engine: Seawall , Rating CEDR=2827   Author - Patrick Heck This is an [UCI] chess engine. It started as an attempt to build a minimal program that was able to play chess. Over  time, it has gained features to make it stronger, but it still implements only a subset of UCI necessary to play  games, and there's almost no evaluation. Some ideas have been borrowed more directly than others; the obstruction difference algorithm is based on the version  from [Chess Movegen], while the use of a low pass filter and capture history for move ordering were borrowed from  [Stockfish].

BlueBetaFish - UCI chess engine Author: Sourashis Mondal Bluebetafish - UCI Chess engine in C++ Overview: Bluebetafish is a chess engine with an approximate rating of 1900. It evaluates chess positions and determines the best moves using minimax search algorithm with alpha-beta pruning. It supports integration with UCI (Universal Chess Interface Protocol) compatible GUIs. Jim Ablet compiles: BlueBetaFish Dev. b3b8603 JA download

  Gravy - UCI chess engine Author: Sammy Humphreys Gravy is a C# UCI-compliant chess engine. Gravy uses a negamax algorithim with alpha-beta pruning. We will start testing the engine on Monday, the first results will be published by the end of the week. Jim Ablett compiles: Gravy 1.0 JA download

  Victoria - UCI chess engine Author: Gaetan Serre ViCTORIA is a UCI chess engine built from scratch using C++ 20. It performs an in-depth analysis and uses a handcrafted evaluation function to evaluate each chess board. It can perform an analysis in reasonable (10-25 seconds) time between depth 6 and 10+, depending on the number of possible moves. Its elo rating is 1694 in blitz (February 2021). ViCTORIA is not a complete chess program and requires a UCI-compatible graphical user interface (GUI) (e.g. XBoard with PolyGlot, Scid, Cute Chess, eboard, Arena, Sigma Chess, Shredder, Chess Partner or Fritz) in order to be used comfortably.
