I'm not sure. It seems that has holes in unusual continuations, like
1.Nf3 c5 2.e4 d6 3.d4 cxd4 4.Nxd4 e5
1.e4 c5 2.Nc3 e6 3.g3 d5 4.exd5
1.c4 e5 2.Nc3 d6 3.g3 Be6
whereafter Ruffian is out of book (for example; I could find more from a 50
games match played with a special 6 plies-book against Ruffian 1.0.1 with it's
original book.)
Probably the relatively small R.book has a chance to be competitive in engine
matches, because (almost) everybody uses "optimal" or tournament book settings,
which basically limit the variety to main variants. I guess the R.book has a
good content for main variants (as it looks like), but maybe not for more seldom
variants like the examples above.
(If those are seldom... I'm no theory expert.)
