s<depth> | "selective" search to <depth> in midgame; higher in endgame. This is the most common setting for Ntest (and the setting used by NBoard) |
f<depth> | "fixed depth" (sort of) |
t<depth> | "turbo endgame" - same as s in midgame but with deeper searches in the endgame |
a<seconds>
[;<WLD depth>] |
spend <seconds> each search on 'a'verage.Optionally force WLD solve at a given depth |
m<minutes> | take a maximum of <minutes> per game ('m'atch time) |
Each <search params> gets its own book. You can rename the books (e.g. rename the book, play a game at match time, then rename the book back). If you rename a fixed-ply book and make it deeper, the program will reevaluate all book positions at the deeper depth next time it starts up. So I never do this, except from/to match time.
