Hi Jeroen,

Take note of this game, the book is the native book of ChessTiger 2004.

[Event "15 Minutes/Game + 10 Seconds/Move"]
[Site "T2004-S8"]
[Date "2004.10.22"]
[Round "34"]
[White "Shredder 8"]
[Black "Chess Tiger 2004 Normal Style"]
[Result "1-0"]

1. e4 c5 2. Nf3 d6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 a6 6. Bg5
e6 7. f4 Nbd7 8. Qf3 Qc7 9. O-O-O b5 10. Bd3 Bb7 11. Rhe1

42. Qc7+ Ka6 43. Bf2 Bxc2+ 44. Kxc2 h5 45. Qc6# 1-0

Tiger shows 14...Re8 as book. Clearly this move losses to 15. Nxg7.

Tiger actually wants to play 14...Bd8 which it scores as +2.16 depth 15.
