Would be very interesting to see, how much the Elo-spreading increases and the draw-rate decreases, using one of my Anti Draw Openings sets...
Especially my new Drawkiller unbalanced openings produced extremly good results in my testings. The Drawkiller_unbalanced_V4_2mvs set would be very interesting. How much could it shrink this crazy draw-rate in your test of 92.3% ?!?

https://www.sp-cc.de/files/pohl_antidraw_openings.7z

Out of my testing-results:
Average result of 6 classical openings sets in my testings (6x 1000 games = 6000 games):
Score (SF 12 point of view): Score: 53.7% (=+26 Elo), Draws 86.6%
Compared to this:
Drawkiller_unbalanced_V4_2mvs: 1000 (+439,=407,-154), Score: 64.3% (=+102 Elo), Draws 40.7% (!!!)

More testing results and informations on my website:
https://www.sp-cc.de/anti-draw-openings.htm

Or, if you dont like the constructed Drawkiller openings, giving an Unbalanced Human Openings set a try would be also very interesting...

Accidentally I took the wrong openings. I have just started the test with Drawkiller_unbalanced_V4_2mvs.
Nevertheless an interesting testrun with my balanced Drawkiller openings. The Draw-rate is 86.1% here, this is better than the testrun with classical openings, you did first: 94.6%. But a little bit disappointing...SF vs another SF on strong hardware is a very drawish setup... But the really good news is, that the Elo-spreading is nearly doubled with balanced Drawkiller: From +20 Elo in the testrun with classical openings to +39 Elo with Drawkiller balanced. Now, I am curious, how much better (?) the results will be, using my new unbalanced Drawkiller openings!
Thanks for testing!
(Mention, that a doubled Elo-spreading means, only 25% amount of played games are needed to get results/rankings of engines out of the errorbar!)
