It may be better to get Tiger out of book in 2 moves and if your engine is strong enough it is going to win the game. I do not believe in big books. I believe that if your engine is good enough to outsearch Fritz7 by some plies then even 1.e4 a5 2.d4 h6 is practically enough for at least a draw and there are better ways to gets the opponent out of book in a few moves.
