Naraku is a free UCI engine. It uses many of the most diffuse algorithms used in modern chess engines: alpha-beta and null move pruning, bitboard, etc. It is in an early stage of development, but already has opening book support and ponder mode.Naraku is written in C++ and it is very fast (about 1-1.5 MNodes/s on a single CPU). The current rating estimates of the engine are at about 2600-2630 points.

The author of Naraku is Michele Tumbarello. The most important releases so far have been Naraku 1.01 (book support), Naraku 1.1 (better evaluation function, better material weight), Naraku 1.2 (adaptive deep reazoning, futility pruning), and the current Naraku 1.31 (better pgo compile, late move reduction, better evaluation function, etc.)

Right after the end of Division F will start Division E, with engines ranked above 2600 ELO points performance, including Gaviota, Redqueen, Daydreamer, Scorpio, Deuterium, and Tornado.
