See the Github release page for the new shortcut commands when using McBrain from the command line.

McBrain is a Stockfish chess engine with a few tweaks and features.

It uses the Cerebellum book and code created by Thomas Zipproth. With the Cerebellum book enabled , it will play about 30 ELO stronger than standard Stockfish. Other features/option include fast play when mate is found ( once McBrain sees mate, it will play very fast , convenient if you're testing). it includes UCI_Limit_Strength and UCI_ELO, a delay option when using UCI_ELO so it will not play instanteously. It includes some Matefinder code (not all) by Joe Ellis and other tweaks to assist in analysis, finding strong moves and mates. And of course, it includes the latest updates from the Stockfish development team which I am deeply grateful for.

Be sure to grab the latest Cerebellum book from Tom's site. It is updated on a regular basis. http://www.zipproth.de

The Github link above has been updated with 4 flavors of Linux exe's, 3 flavors of Win 64 bit exe's and two flavors of Win 32 bit exe's, all flavors are contained in zip files. Enjoy!

Try again - apparently, two of the uploads failed, but they should be good now.

It's Stockfish with the the cerebellum book , minus play by elo and some of the matefinder code and other changes , which makes it a clone of Brainfish more or less . The source identifies it as Stockfish code, the fact that it is named something else is probably preferable so at least users know it's not the official source. I did not check to see what if any changes he made , but at quick glance he had not cloned McBrain - but if he did that was his right to do so .

This month a hacked version of the Botvinnik-Markoff extension was added for maybe a couple of ELO in addition to the normal UCI tweaks, features and SF commits or soon to be commits. Testing above was with the Cerebellum book off - the Cerebellum book by Thomas Zipproth (Brainfish Author) typically adds about another 30 ELO when using widely played openings. Note : My GitHub page does not have the current source.
