Hi Dom,

I noticed in Hydra's previous match with Shredder that its opening book was
indeed quite shallow. Worse yet, some lines that Hydra played into were lines
that it had previously played.

Therefore, I would think that if Hydra had experience in certian lines that its
team would do some post-game analysis of the opening. If the line played was
acceptable, then I'd expect the team to extend that specific line at least a few
ply further, with a net potential time gain for future games, not to mention
less calculating time for the opponent, who now can't calculate on Hydra's time.

All the best,
Steve
