Arasan 26 - new version chess engine (Windows, Android, Linux)

on

A new version of one of the longest-developed chess engines has been released - Arasan 25.4. The engine plays very strongly and is ranked high at 22th place in the CEDR ranking. We will start the first tests of this engine soon. 

Arasan - UCI engines Author: Jon Dart
Rating Chess Engines Diary CEDR=3668

Arasan has both a native user interface (for Windows only) and a console-based chess engine for use with Winboard or xboard. Arasan also works with Arena, another free chess interface, and with UCI-compatible programs like Fritz and Chessbase.

Arasan includes an opening "book" with over 900,000 moves.
