Been a tough go for HIARCS so far. Here was a round 3 loss, starting from a tablebase draw:[White "HIARCS 13.2"][Black "Junior 12"][Event "TCEC B"][Round "3.1"][FEN "8/5p2/7k/8/1p4K1/3B4/8/4b3 w - - 0 77"][Result "0-1"]

Seem rather clear the King should stand close to the f-pawn.

Cheers for Zappa. Amazing the old engine can still hold its own.

Crunch time for HIARCS, needing a last-round victory over Spike to avoid relegation. Enter the Cunningham Gambit:
[White "HIARCS"][Black "Spike"][Event "TCEC B"][Round "10.3"][Result "*"]
1. e4 e5 2. f4 exf4 3. Nf3 Be7 4. Nc3 Bh4+ 5. Ke2 d5 6. Nxd5 Nf6 7. Nxf6+ Qxf6 8. d4 Bg4 9. Qd2 Nc6 10. c3 g5 11. Kd1 Bxf3+ 12. gxf3 O-O-O 13. Kc2 Rhe8 14. Qg2 Qd6 15. Bd2 f5 16. Be1 Bxe1 17. Rxe1 Nxd4+ 18. cxd4 Qxd4 19. a3 h5 20. Kb1 g4 21. Rc1 gxf3 22. Qc2 Qxe4 23. Bh3 Rd5Seems that Black didn't play this too well for a few moves there, and the piece sac has gone down the drain with only the isolated tripled pawns to show for it. Spike took an hour for the first 6 non-book moves, while HIARCS took about 15-20 minutes.

Congratulations to Spark (& Allard Siemelink!) for winning
this in style being the only undefeated engine.

See you all in 3 days for TCEC A with the strongest engines on the planet.

Best,
