Unbalanced Human Openings V2.00 released

[Werner]

Hi Larry,
why do you think so?
Does this happen too allthough each opening is played with black and white ?
My ideas is there are less draw games when using unbalanced openings.

Yes, it reduces draws a lot. This is fine if all testers in a group use it, but if some testers use it and others use normal (drawish) openings, the elo differences will pretty much just depend on the relative number of games played by the two book types. Just for example, if you are testing a new top level engine like SF or Dragon, it will get a much higher rating if a high percentage of games are played with UHO than otherwise. Of course if all engines were tested with say half UHO and half normal openings that would be fine, but that is unrealistic given that each tester makes his own choice.
