I tried various logical options including yours, to no avail. Then looked into the executable and unfortunately a command-line option for fixed depth does not exist. Will have a look at Winboard then Wink


Obvious question: "Why fixed depth?" Are you SURE that the two programs have equivalent "plies"? Identical extensions and reductions and such, so that this is not a handicap match where the handicap is not obvious???

I am using cutechess-cli in the meantime. To test my eval I run fixed depth self-play matches controlled by a depth based flexible parameter. For instance when I set the following parameter [PLY = 8] as a base then:

1. midgame positions will be done 8 plies
2. midgame (minus queens) 10 plies
3. normal endgame 11 plies
4. rook endings 12 plies
5. minor endings 13 plies
6. pawn endings 14 plies
7. queen endings 10 plies

When I raise the parameter to 9 all depths increase with one and vice versa. When I have a handful of improvements I try them with regular time control.

I am indirectly using the system also to measure the impact of search changes. Say you add a static reduction which gives you a 10% speed-up but loses 20 elo points, it's likely a bad idea. Getting insight in the mysterious ways of the search is the keyword here.
