You think so?

In many blitz tests at 40/5 time control against version 2.00, I got a 70 ELO
improvement (according to ELOStat) and in 40/30 time control, I got around a 40
ELO improvement. But then again, most of the changes I made were in the search
and not the eval so it may not "look" like it is playing better but it solves
most tactical (and very few positional) tests faster than 2.00.
