This quote dates from last moves at chessgames.com by Chrilly Donninger the
programmer of Hydra about why they have Hydra book at 20ply. I posted this a few
weeks back ;)

"Opening preperation is certainly a critical point. We use a very short opening
book. Maximum 10 moves, sound main variations. Then we leave Hydra from the
lash. I think it is difficult to find within the first 10 moves in
main-variations killing-novelties. It is possible to find something afterwards.
But Hydra is difficult to predict and it has already refuted some lines. Testing
the novelty with Fritz is no real guaranntee. If the GM deviates quite early
from theory, he has less time per move and has to do much more calculations."
