I have. I always test the newest version vs 16.19, 17.14, 18.15.

19.20 scored 20% better against 16.19 (the best known version to date) than all
the previous versions. 19.19 lost all it's matches against the "big three".

I also ran a 25 game match at 60 10 between Gandalf 6.03 and Crafty 19.20. The
result was +11 =5 -9 in favour of Crafty 19.20.

Overall I am quite impressed with this new version. I can't say I thought the
same about the 19.xx series as a whole.
