Stockfish
UCI chess engine
Stockfish is a free, powerful UCI chess engine derived from Glaurung 2.1. Stockfish 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. Read the documentation for your GUI of choice for information about how to use Stockfish with it. Stockfish is a 11-time winner of the Top Chess Engine Championship. Stockfish is open source (GPLv3 license). That means you can read the code, modify it, and contribute back. You can use Stockfish on your computer or on your iOS or Android device. So you can get world-class chess analysis, wherever you are. The Stockfish engine features two evaluation functions for chess, the classical evaluation based on handcrafted terms, and the NNUE evaluation based on efficiently updatable neural networks. -

Chess-gambiteer
Chess training program playing gambits
Program to train against gambit play (*) with the computer, with a strength adjustable chess engine (Danasah, currently set at approx 1400 EL0 when playing against it). Also included now are two options to watch an engine e.g. the 'aggressive' Patricia5 (with gambits) play against another engine (eg IM level). The engine gambit books are made in such a way that 1) real lousy gambits are not played, and 2) the book is choosing a gambit line as often as possible, so for Black it might go for e.g. a Benko gambit or so and if you let it play with White, a lot of 1.e4 gambits can be played. Thereby, if you try a gambit yourself, the program might try to a counter-gambit (or sometimes an unconventional line). It will play weak against other engines, and it not meant as to play very strong/perfectly, but for human opponents, the gambit lines will most often result in entertaining -not boring- games, and require quite some concentration to avoid tactical mistakes. -

Kenny
"Kenny" is an XBoard/WinBoard chess engine based on "Winglet"
Kenny is a Winboard/XBoard chess engine based on Winglet (http://www.sluijten.com/winglet/source/index.htm), an open source chess program. Winglet's full source code can be obtained from Winglet. Kenny is an advanced form of Winglet which plays better at some faster time levels like blitz chess or upto 20 minute games, but almost always loses against Winglet when the time controls are 40 minutes or more for each. These tests were run by setting up various tournamennts on the free Chess GUI Arena Version 3.0. Kenny uses modified values for evaluation of various parameters, thus introducing almost an entirely new engine, because the evaluation function is the heart of a chess engine.
