I thought winboard's "default_book.bin" would work in the online tourney. It works in local matches. I saved the settings. But "Nameless" searched right from move #1.

What additional step is needed?

I think the comments tell most of the story.

Your first mistake is playing the Scandinavian. White's 7. Bd3 looks like a novelty. But 7. c5 here scores very well for White. Black should not go into this line IMO.

39. .. Rg6 is much better than the played move Rg3+.

On move 43, Black had .. b6, which Stockfish scores as over +5.

On move 44, .. b6 throws away all Black's advantage. I think though Black could still have drawn with best play.

You must make sure the option "First has own book" is unticked in the Common Engine Settings. Or use the command-line option -firstXBook. This is a volatile option (since it is engine-specific).
