71st Amateur Series Division 9

[Graham Banks]

Surprised I am, enormously.

A nice surprise though.

Perhaps 2.0.0 is stronger on 1CPU than 1.0.3. I'll run a gauntlet soon to find out.

I'm sorry but this can't be right
Are you sure Embla did not played with multiple threads? Definitely not.
Because that version you played with is in my own tests at least 120 elo weaker than dorpsgek:

Code: Select all

Rank Name                  Elo    +    - games score oppo. draws
   2 dorpsgek             2195    2    4 374418   62%  2108   28%
  56 4875                 2072   10   10  3569   33%  2195   27%

4875 is Embla, a bit more recent than 2.0.0 even.

Also: even with 4 cores and by cheating a little (Dorpsgek in a VM and Embla directly on hardware) it is still 20 elo weaker:

Code: Select all

Rank Name                  Elo    +    - games score oppo. draws 
   2 dorpsgek             2195    2    4 374506   62%  2108   28%

(neo-b is also Embla)

Not enough games to jump to conclusions yet of course.
Definitely a poor tourney for Dorpsgek so far, but less than 20 rounds played so far.

(neo-b is also Embla)

I had experiment myself some trouble playing against dorpsgek. One day Weini is equal (+/-20), the other day -100(+/-20). Last month I tracked a supposed regression for days based on that kind of match against dorpsgek and never really found it. I mainly use CT800 or Isa now when I do 1on1 test matches (and many engines for graunlet).
