Cfish is back!

Cfish 11a- 8 cores 2048 MB Hash:
44/64 13:45 6.094.447.028 7.384.049 +1,59 Dd2-e3 Ta8-b8

This is the official popcntn windows version from the github page.

i doubled the cores and the result is clearly worse against the old version with only 4 cores.

Not so nice.

Please run each search with 1 thread. Then compare.

Your "old" version of 6 July is a lot more recent than Cfish 11a, which is now (hopefully) functionally identical to Stockfish 11 (at least for single-threaded searches).

Same version Cfish 11a with 2048 MB Hash and just 1 core:

Testing on one or a few positions is meaningless.

Gentleman, i repeated the test only doubling the hashsize from 1028 to 2048 MB:

Once again, the latest version of Stockfish didn´t make me happy.
