Reminder: Stockfish is best with 2 cores

I have zero interest in doing your work for you or convincing you. I work with the others who have done the testing and understand this.

I've done my own testing and continuing to do so. I'm not asking you to do work for me, I'm asking you to share some positions from the work you've supposedly already done. But there's nothing! You've provided zero evidence in this forum - not a single position to back up your hollow claim. You want to make claims with secretive proof. It's not about whether you want to convince or not; it about whether you actually can or not.

I done testing previously and more recently:

2 threads: 112, 68, 50, 343, 3874, 756, 17, 26, 51, 250, 508, 235 (time in seconds to solve)
16 threads: 22, 17, 14, 464, 28, 44, 10, 3, 0, 15, 134, 50

I'll repeat these runs multiple times but so far the 16 threads was faster on 11/12 positions.

Another run:

2 threads: 48, 81, 47, 619, 4114, 1351, 18, 3, 15, 21, 308, 180
16 threads: 28, 12, 7, 125, 2812, 114, 5, 0, 8, 63, 60, 16

Again, 16 threads faster for 11/12 - and the slower position is different from the 1st run. I realise that only using 12 positions is such a small sample but I'm prepared to see only a small amount of positions that show 2 threads being as good as 16 threads. And my 12 positions are from public test suites or test positions posted previously in the forum.

I looked at the discussion on Discord - interesting to see what was actually said.

I downloaded some HTC file with 115 positions and it seems at least all the first 4 positions have more than one winning move so the test suite is bad.

No idea what you downloaded.
The original HTC114 test is here in the forum.
