Engine match

[rigao]

Is it posible to play an engine match from a set of positions using xboard?

If so, how exactly?

thanks

xboard -mg 10 -lpf STARTPOS.fen

would play a match of 10 games from the start position in the file. If there are more positions in the file you can specify you want to play from number N with -lpi N. If you specify -lpi -1 it would start at position 1, and play every game from a new position. With -lpi -2 you would play every two games from a new position. If you add -rewindIndex M you would start at game 1 after having used the first M positions. (For if you ask for more games than you have positions in the file.)

The same works if you want to play from openings given as PGN; in that case you have to use

xboard -mg 100 -lgf OPENING.pgn -lgi -2 -rewindIndex 10

to play the first 10 openings of the file 10 times (in 5 pairs of white and black).

Of course you would have to specify engines as well, if you don't want Fairy-Max to play itself. Plus things like time control and other parameters, if you don't use XBoard 4.20100118, which loads them from the settings file.
