FRC / Chess960 Engine with "Divided" Command

[Steve Maughan]

I'm trying to add FRC / Chess960 capabilities to Maverick. It's proving to be a more complex than I anticipated.

I'm currently debugging my move generator using a FRC perft routine. It looks as if I still have some errors.

Here's my question - does anyone know of a FRC engine which supports the "divide" commands i.e. prints out the nodes searched under each possible move?

I used Sharper when I was debugging the regular move generator but it doesn't support FRC.

Thanks - Steve

Seems Hermann engine by Volker Annuss supports "divide":

Stockfish?

Supports FRC and has command named perft that takes a single depth parameter and gives "divided" output.

Sjaak has this.

Simply give

Code: Select all

variant fischerandom
setboard <fen>
perft N 1

to perform perft N on the given position and print out the number of nodes under each move at depth 1.

Sjaak II accepts "chess960" and ""fischerrandom" as alternative names. In fact, setting "variant fischerandom" is optional, since Sjaak always plays FRC when it claims to be playing Chess.

Awesome - I'll take a look!
