On 19x19 I agree with Magnus and I would add that it's almost impossible to "stay in book" very long as the number of reasonable plays of the first 6 moves (for instance) is already enormous.
Even in chess you can quickly move out of book with non-standard moves that do not lose and chess is ridiculously simpler than go with respect to the branching factor.
