Defenchess

Overview

Defenchess is a free, open source UCI chess engine written in C++. This project has been created purely as a hobby and a challenge for ourselves to create a strong chess engine. It is meant to be used with a UCI compatible chess GUI.

Parameters

• Hash

  The size of the transposition table in megabytes. (default 16)

• Threads

  The number of threads used while searching. (default 1)

• SyzygyPath

  The path to the Syzygy Tablebase WDL/DTZ files. (default empty)

• MoveOverhead

  The minimum amount of time in milliseconds to be left on the clock while moving. Should be increased if the engine is losing on time. (default 100)

• Ponder

  This parameter is just to tell GUIs that the engine is capable of pondering. The engine will respond to the "go ponder" command regardless of it being set to true or false.

• UCI_Chess960

  This parameter will let the engine play Chess960 (FRC) when set to true.
