FGRL, 60 sec + 0.6 sec - 2. Dragon by Komodo Chess 1.0, 7. Komodo 14.1 MCTS, 10. SlowChess Blitz Classic 2.4

The result with Slow 2.4 slightly below 2.3 and 2.2 does come as a surprise even knowing the gains might not show up so much against weaker opponents. In SPCC and in the CEGT forum I see a 20+ elo gain for 2.4 vs 2.3, and versus the older 2.2 I got +42 elo standard, +51 FRC in my own testing. Not having AVX2 should only matter slightly since it's just endgame nets will be about 30% slower, which even without AVX2 was still stronger than no nets. Will see how it does in the other tests. (Just in case : Slow64-noAvx.exe should be the one to use, the Slow64-noPop.exe is like 6-8% slower overall for me, and the Slow64.exe I assume would crash. Also with 2.4 it expects the data files in the same dir as the exe now but the zip has been arranged this way so still just a straight extract.)

Thanks for your explanations.
I took as usual the Slow64.exe without the endgame nets!
So I will repeat the games with the Slow64-noAvx.exe and the included endgame nets.

Thanks for re-testing, at least it inched in the right direction this time. Hopefully will make more difference against stronger opponents.
2.4 is mostly just 2.3 with the endgame nets added. (I guess maybe had worse luck than 2.3 first test.)
