My test for Koivisto_4.0-x64-popcnt-avx

[Sylwy]

Test conditions:
-TC=4'+2"
-Hash=256 MB
-GUI: Arena 3.5.1
-Books: Perfect_2010.abk (Koivisto 2.0 x64 bmi2) and RanomiV16.bin (Gogobello x64 bmi2)
-default settings for both engines
-1 thread-CPU=Intel i5-7400-3GHz (Kaby Lake)
-6-men Syzygy bases for both engines
-OS: Windows 10 Home.







Gogobello 2.2 x64 has 2991 Elo points (CCRL Blitz).
Koivisto 4.0 x64 popcnt-avx has around 3060 Elo points in my test.
Koivisto 3.0 x64 popcnt-avx has around 3055 Elo points in my test.
Koivisto 3.0 x64 has 3023 Elo points (CCRL Blitz).

Of course, my tests using a single engine are not statistically relevants. It's just a clue. Let's see the results of CCRL &
CEGT.

Very disappointing results indeed. Hopefully its just a fluke
