I just tested it with Spike 0.9a making moves for both sides (by repeatedly pressing the space bar; no Fritz book was loaded). The book produced variants 16 moves (31 plies) long, after 1.e4 and 1.d4. See below. The book depth seems to be ok. I guess in your test, unusual moves were played early. I don't know if the Spike book is a narrow or wide repertoire. When you post some of your short book variants, other users could check this. 1. e4 c5 2. Nf3 Nc6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 d6 6.
