CCCC rounds 43,44 and 45. First stage is over!




1st stage is almost over, 1 round remains but the top 8 engines that will participate in stage 2 are known.
Stockfish, Komodo, Houdini, Leela, Fire, Ethereal, Andscacs and Boot promote to next round.
Next round, unlike this round, would be without pondering and every engines will play every other 10 times so we would have a total of 70 games per engine.

Andscacs won Arasan in the final round so Shredder has no hope to promote.



ROUND 43
 In this round Leela destroyed Shredder's hopes for promotion by winning him after a superb game where it completely outplayed Shredder with a startling exchange sacrifice that Shredder(as also other engines like the mighty Stockfish) had no idea about it. The defense that would lead to draw was very thin and Shredder didn't manage to find it. To him as also to other engines most moves drew easily. But that was not the case as the genius Leela knew in this game!


505 Andscacs vs Ethereal 1/2-1/2
506 Fire vs Crafty 1-0
507 Booot vs Fizbo 1-0
508 Fritz vs Arasan 1/2-1/2

Not judging from this game but generally, Leela's eval is so much superior to all other engines, Stockfish included, that in some positions shine so much, like here. She knows this must be winning. But it's not :) The drawing line though, is very hard to find and one has to dig incredibly deep to dismiss countless other moves that seem to hold but in fact are losing for just one tempo most of the times. But there is a line that seems to lead to a draw. But judging for over the board play, in real game time play, the move deserves 2 exclamation marks for creating a situation impossible not just for Shredder, but for most engines or humans to handle over the board since white is winning in most variations creating startling zugzwang situations.

ROUND 44
Komodo won against Shredder making things worse for its promotion chances.
While Leela in a complicated game with semi closed position and many pieces on the board, outplayed Pedone as it was expected and reached a winning position. Yet she blundered throwing away the win with 63...Bxd5?
But once again afterwards analysis showed that if Leela was using its Lc0 binary of now, that is with support for endgame tablebases, it would avoid the blunder in less than a second and would win.

Here follows the analysis of the position with Lc0 11089 net but with 3,4,5,6 syzygy TBs where we can see Leela avoids the drawing move in 1 second.
In the game analysis below we can see and the test game of this Leela against Stockfish where it wins easily when she uses tablebases.

So now along with the game against again Pedone with Leela having white, the game Leela-Komodo and the current game, Leela has lost 1.5 points that if she were using tablebases she would have won them.
She also drew a won game against Crafty because of a blunder but Leela with TBs would not have found. So 2 points thrown because off bad endgame play.

ROUND 45
Leela won an easy game against Nemorino that didn't provide any resistance.
Shredder had its 3rd loss in the last 3 games and didn't manage to welcome the gift of Booot that won against Andscacs, so its hopes for promotion are based on Arasan to draw the game with Andscacs.

Booot is the pleasant surprise of this tournament so far since no one believed it has chances to promote!


529 Andscacs vs Booot 0-1
530 Crafty vs Arasan 1/2-1/2
531 Xiphos vs Ethereal 0-1
532 Fire vs Wasp 1-0

  1. Thanks for the further analysis of the Shredder game -- there was a lot of fun trying to understand the positions following ...Rxc3 before and after ...Rxd5, and yeah it does seem to be a draw after all with best play. But still, the exchange sac was wonderful vision and made for a superb game!
