I like it due to the fact that you can adjust the engine strength.

strong engine

Strong engine, up there in competition with black mamaba 2.0. Makes slightly better or worse moves at times which I like about it, giving it it's own playing style, but tends to crash on auto play at end game. Hoping to see updates to this and performance and strength.

It does not work with my new phone and it still stops on 8 cores. Can the developers do something about it it crashes on auto play.

About this app

Chiron 3 is about 60 points stronger than Chiron 2, supports multiple processors, Polyglot and CTG opening books, several endgame tablebases formats (Syzygy, Gaviota, ...). If you want a chance to win against Chiron, you can limit its playing strength (feedbacks are welcome). If you have played Ubisoft's Watchdogs you might already have played against a much weaker version of Chiron.
Chiron comes in both Chessbase and Open Exchange formats.
