Tournament State:
We are halfway through the first rotation (1.300/2.600 games). In this 8-engine Round-Robin, the hierarchy is becoming crystal clear. Stockfish 18 and Stockfish 17.1 are currently in a league of their own, occupying the top two spots with 65.3% and 62.1% respectively.

The TCEC Opening Massacre:
The biggest story of this RR so far is the extreme opening bias.
  • [] White Wins: 49.77%
    [] Black Wins: 1.54%
  • Draws: 48.69%
With only 20 Black wins in 1300 games, the engines are fighting an uphill battle from move one. In a Round-Robin format, this puts immense pressure on the top seeds to convert their White games, as a single slip-up is impossible to recover with Black.

Key Head-to-Head Findings:
  • [] Stockfish 18 vs. The Field: SF18 is steamrolling the lower half. The 95.45% score against Obsidian and 91.30% against Komodo Dragon are devastating results for a Round-Robin of this level.
    [] The Mid-Tier Battle: Reckless 0.9.0 is performing admirably at 55.5%, successfully distancing itself from its predecessor (Reckless 0.8.0) and showing significant Elo gains (+18.3).
  • Dragon in Distress: Komodo Dragon 3.3 is struggling significantly in this rotation, sitting at the bottom with only 36.1%. It has failed to reach a 30% score against 6 out of the 7 opponents.
Current Trajectory:
As we move into the second half of Rotation, the gap between the "Stockfish Tier" and the rest of the field continues to widen. The S-B (Sonneborn-Berger) scores already indicate a massive lead for the top two seeds, making this a race for 3rd place for the rest of the participants.
