Some of the defaults are specified in:

They are defined in the file engine/utils.c:

#define DEPTH                16
#define BRANCH_DEPTH         13
#define BACKFILL_DEPTH       12
#define BACKFILL2_DEPTH       5
#define BREAK_CHAIN_DEPTH     7
#define FOURLIB_DEPTH         7
#define KO_DEPTH              8

Of course the faster you run it the weaker it will be. There's
some other depths set in utils.c that you could try playing
with. I don't think everything can be set with a command line
option, so you may have to rebuild to change some things.
