Alichess 4.06 by Anton Lindenmair (Germany) proved its supremacy
in this tournament garnering 7.5 points ahead of 2nd
and 3rd placer BBChess 1.01 and Anechka 0.08 both
with 7.0 ponts.
The next ranks
were shared respectively by Adam 3.0, Gibbon 2.13d and Monarch
1.7, each having 6.5 points. The results were well distributed
among the players on half-point differences.
On the
average, we could assume that half of the league is about
± 50
ELO points in range.
Of the top 5 engines, only Gibbon, Alichess and Anechka stood their ground. BBChess 1.01 was a truly better upgrade than previous (v0.99).
Madeleine 0.2 could only salvage 8th place with 6 points (not bad!) and was replaced by Adam 3.0 on the Magic 5 list.
Our guest engine Cheops 1.1UCI, a Linux based experimental AI chess engine by Tristan Miller (compiled for Windows for UCI support by Michael Yee),
succumbed to last place with a winless record. At least it played a smooth game of chess and following the protocol rules by the book.
Another interesting observation is the high percentage of white wins of 60% (blsck wins = 27%, draws = 13%)
and an even usage of opening lines from ECO A to ECO D of about 22 % to 25%. (with ECO E usage of only 7%). I
n the past leagues, using the Noomen Test Suite, engines usually avoid the ECO A lines.
