Total: 19484 W: 3903 L: 4956 D: 10625
20000 @ 15+0.05 th 1 Test SwordFish against Master. Since the -34 ELO try, I have reverted a bad mobility tune, tuned the knight outposts and narrowed the focus of the project by restoring endgame PSQT (in simplified form). This time, the end ELO difference should be close to -15. NOTE: This will be the last test relating to SwordFish unless Marco gives me the go-ahead, but it is critical to know how far off this version truly is, especially for the ability to make informed decisions.
