Ultra-Bullet Placement Cup - First Edition

[goni-K26]

Ultra-Bullet Placement Cup - First Edition

32 engines, 5 rounds, every place from 1 to 32 decided over the board

The idea

In a normal knockout cup half of the field goes home after the first round, and we never learn who was really 9th or 23rd.
In this cup nobody is eliminated. Every engine plays all 5 rounds:

• the winners of each round go on to play for the upper half of their places, the losers for the lower half;
• after round 1 there are two groups (places 1-16 and 17-32), after round 2 four groups, and so on;
• in round 5 every pair plays its own "final" for two places: 1-2, 3-4 ... 31-32.

So every engine plays exactly 5 matches and finishes with an exact place from 1 to 32.

Format

• Fixed bracket, tennis style: seeds 1 and 2 can only meet in the final for 1st place.
• The matches get longer every round, because the engines get closer to each other:

R5 (Finals)         |         100 |      16 |  1600 |       50 | Sicilian Defense (20) + 30 lines of other families
Total               |         222 |      16 |  3552 |      111 | 5 main families + 30 lines of other families
--------------------+-------------+---------+-------+----------+---------------------------------------------------

• Each opening is played twice, colours reversed (opening k = games 2k-1 and 2k).
• The higher seed has White in game 1, then the colours alternate.
• A new round starts only when the whole previous round is finished.

Tied matches

1. Tiebreak: 10 games at 2s + 0.02s, with openings 1-5 of the round.
2. Penalties: pairs of 2 games at 2s + 0.02s (openings 6, 7 ... and then again from 1), until one engine wins a pair (2-0 or 1.5-0.5).

No replays

Time forfeits, illegal moves and quick draws all count as they are: the best one wins.
Only a game that did not really happen (no result) is played again, up to 3 times.

Openings: the classical games of Magnus Carlsen

• Source: Carlsen's classical games from 2001 to July 2026 (rapid and blitz games filtered out).
• Each round uses one opening family, from his most played families. Round 5 adds lines from the families not used in any other round.
• All openings are 8 moves (16 plies) long, and every line is Carlsen's own most played line in that group.
• No position and no line is repeated in two rounds.

Stories of the round

• The only upset: Igel. Astra (seed 12, Premier) and Igel (seed 21, First Division) drew 15 games out of 16. The only decisive game was game 4, a win for Igel with White in opening 2 (E55). One game was enough: Igel goes on to play for places 1-16, Astra for places 17-32.
• Reckless at full speed: 14.5 - 1.5 against Koivisto, 13 wins and 3 draws, the biggest score of the round.
• Alexandria with only one win: 8.5 - 7.5 against Uralochka (seed 30), 1 win and 15 draws.
• No replays: PZChessBot lost game 3 against PlentyChess on time, and the game counts as it is. 14 quick draws also stand.
• The most drawish opening was opening 1 (E37, Classical Variation): 29 draws in 32 games. The most decisive was opening 8 (E30, Leningrad Variation): 14 decisive games, and 8 of them were won by Black.

Ultra-Bullet Placement Cup - 1st Edition

Round 2 - Round of 16 (24 games per match)

Round 2 brought no surprise at the top: the eight highest seeds - exactly the top 8 of the Premier Division - all reached the quarter-finals. It also brought the first tiebreaks of the cup. Pawnocchio and Caissa drew 12-12, and Pawnocchio won the tiebreak 5.5-4.5. Horsie and Tarnished drew 12-12 and then 5-5 in the tiebreak, and Horsie won the penalties 2-0.

The biggest score of the round: Alexandria 18.5-5.5 Komodo Dragon, 13 wins and not a single loss. In the lower half four engines beat a higher seed: Halogen (over Motor), Tcheran (over Starzix), Quanticade (over Minke) and Uralochka (over Renegade).

Openings
12 lines from Magnus Carlsen's games, each played with both colours (opening k = games 2k-1 and 2k).
