RubiChess - the New Chess Engine on Chessify

Another UCI-compliant chess engine, RubiChess, is now available on Chessify and can be used at up to 130 MN/s speed! 

We've added RubiChess at the request of our recent survey participants and Discord community members. To share your suggestions and feature requests with us, please join our Discord channel.

About RubiChess

In development since 2016, RubiChess is currently ranked number 9 in the CCRL 40/15 Rating List and participates in most big chess engine tournaments.

Starting with version 1.9 released in November 2020, RubiChess has supported evaluation using NNUE weight files. With the latest 2.0 version, however, NNUE evaluation became the default. Chessify offers both versions of RubiChess on its Analysis Dashboard. Although we recommend you use the NNUE version, you may still use the standard version without NNUE for the so-called handcrafted evaluation.

RubiChess is an open-source engine developed by Andreas Matthies. You may find the detailed feature list of each development version in the engine's ChangeLog on GitHub.
