Clover led the table after Matchdays 2, 3, 4, 5, 6 and 7 - and lost its first and only game on the last night. From first to sixth in one game. The engine that beat it: Viridithas, who had started the league phase with a defeat and now takes the last direct ticket to the round of 16. PlentyChess (Paris) beat Eleanor (Galatasaray) and wins the league phase.

2026 - Chess Engine Champions League (Knockout Phase Play-off)

Post by goni-K26 »

2026 - Chess Engine Champions League (UEFA Champions League Mirror)

Knockout Phase Play-off

Sixteen engines, eight ties, one ticket each to the round of 16. The draw (seeded within the UEFA pairs 9/10-23/24, 11/12-21/22, 13/14-19/20, 15/16-17/18) produced eight ties - and the Modern Defense turned the second leg into a home fortress: six of the eight ties were decided by the seeded engine winning with White.
Spotlight: Astra (Roma) 1-0 Starzix (Real Betis)
The only unseeded engine to go through in normal time. Astra won the first leg with White and held the return leg level after 300 plies. And in extra time Alexandria (Atleti) was merciless: 5-0 against Motor (Aston Villa), five wins in ten bullet games.
Format: Two legs, one game per leg, Modern Defense (opening 3) in both legs. Leg 1: unseeded engine White - leg 2: seeded engine White (the return leg at home). Level after two legs: extra time, 10 games at 9s + 0.1s (5 openings x 2 colours, the extra-time openings of the 2026-CENL); still level: penalties, 10 games at 2s + 0.1s, then sudden-death pairs.

2026 - Chess Engine Champions League (Round of 16)

Post by goni-K26 »

2026 - Chess Engine Champions League (UEFA Champions League Mirror)

Round of 16

The top 8 of the league phase enter the stage - and two of them leave at once. The draw followed the fixed UEFA bracket: places 1/2 against the winners of the 15/16-17/18 play-off ties, 3/4 against 13/14-19/20, 5/6 against 11/12-21/22, 7/8 against 9/10-23/24.
Spotlight: Alexandria (Atleti) 3-2 PlentyChess (Paris) after extra time
The winner of the league phase is out. Two goalless legs, then a bullet thriller: Alexandria led 1-0, 2-1 and 3-2, PlentyChess equalised twice, and Alexandria's third win came with White in ET9. Caissa (Inter) beat Clover (Sporting CP) 3-2 after extra time as well, Obsidian (Arsenal) knocked out Stormphrax (Barcelona) with a 37-move win, and Renegade (Porto) beat RubiChess (Club Brugge) - still unbeaten in the whole competition.
Format: Two legs, one game per leg, Modern Defense (opening 3) in both legs. Leg 1: unseeded engine White - leg 2: seeded engine White (the return leg at home). Level after two legs: extra time, 10 games at 9s + 0.1s (5 openings x 2 colours, the extra-time openings of the 2026-CENL); still level: penalties, 10 games at 2s + 0.1s, then sudden-death pairs.

Chess Engine Champions League (Quarter-finals)

Post by goni-K26 »

2026 - Chess Engine Champions League (UEFA Champions League Mirror)

Quarter-finals

Four ties, no extra time - and three times the seeded engine went through by winning the return leg with White.
Spotlight: Obsidian (Arsenal) 1-0 Pawnocchio (Real Madrid)
The 2026-CENL champion is out. Obsidian won the first leg with White in 198 plies and survived 240 plies in the return leg - its second knockout of a big favourite after Stormphrax. Viridithas (Man City) beat Alexandria (Atleti), Reckless (Bayern) beat Caissa (Inter) and Integral (Liverpool) ended Renegade's (Porto) unbeaten run.
Format: Two legs, one game per leg, Modern Defense (opening 3) in both legs. Leg 1: unseeded engine White - leg 2: seeded engine White (the return leg at home). Level after two legs: extra time, 10 games at 9s + 0.1s (5 openings x 2 colours, the extra-time openings of the 2026-CENL); still level: penalties, 10 games at 2s + 0.1s, then sudden-death pairs.

One semi-final decided in normal time, one in extra time.
Spotlight: Viridithas (Man City) 2-1 Reckless (Bayern) after extra time
Viridithas won the first leg with White, Reckless answered with White in the return leg. Four draws opened the extra time, then Viridithas scored in ET5, Reckless equalised in ET8 with a 33-move win, and Viridithas struck again in ET9. The number 1 on the rating list is out. In the other semi-final Obsidian (Arsenal) held Integral (Liverpool) for 142 moves with White, but Integral won the return leg - promoting on g8 and mating.
Format: Two legs, one game per leg, Modern Defense (opening 3) in both legs. Leg 1: unseeded engine White - leg 2: seeded engine White (the return leg at home). Level after two legs: extra time, 10 games at 9s + 0.1s (5 openings x 2 colours, the extra-time openings of the 2026-CENL); still level: penalties, 10 games at 2s + 0.1s, then sudden-death pairs.

How the final was won
Viridithas won all three of its first White games - Owen, Modern and the Queen's Pawn with ...b6 - and led 3-1 in goals after six games. A draw with White in game 7 was enough: the title was secure before the last game. Integral's win in game 8 only made it 4.5 - 3.5. Game 1 was Integral's first defeat of the whole competition, after 8 league games and 6 knockout games without a loss.
