Young test shows AMAZING Stockfish progress

[Jouni]

Current version is with one thread much stronger than SF8 with 64 threads! Current score 12 - 0 for one thread. And note how much higher depth 1 core has. 60 moves / 60 minutes:

1. Stockfish dev 18 (1 CPU) depth 68.6
2. Stockfish 8 (64 CPU) depth 52.4

Sure !
1 thread vs 1 thread is about +400 to +450 Elo for SF 2025-2
