Round 7, Black vs Jonny

Some tactical blindness cropped up today. Leela dropped a queen to discovered attack. It happens. Although Leela had some mate threats even material down, Jonny was able to make progress and the team decided to resign.

Hopefully the 20b network will allow better communication between different parts of the board and these kinds of blunders will be a thing of the past.

Round 5, Black vs Shredder

The devs tinkered with a tiny opening book, so we got 1. e4 c5. Leela sans opening book proceeded to blunder into a sharp line in the Najdorf Opocensky variation after 11. f5! Shredder ran out of gas on it’s kingside attack and Leela rallied. Play was sharp for a while until it ended quietly in a TB draw. Imagine what Leela could have done with an equal or better position. Right now she is no match for theory.

Round 1

Leela had white with Komodo (12 I assume). The game ended up in a TB draw (and there may have been a few opportunities to claim a 3-fold around move 93), but the flag fell. 0-1.

More on the WCCC

First off a warm thank you to our Cyril Guyot (@Cyril on discord) who paid the late entry fee and convinced his employer, Western Digital, Research, to provide a monster machine with 8xV100’s to run leela. Cyril will be operating leela during the tournament. Hopefully some other community members will be there so he can take a bathroom break.

Down Goes Stockfish! Down Goes Stockfish!

Leela Beats Stockfish

It’s happened before, but when it happens on a big stage at a longer time control against a Stockfish on TCEC’s beefy 43 core setup, you have to sit up and take note.

King Crusher was at the scene in record time with a video.

Note that Leela was running on a remote machine with two 1080’s (ti?). A rough estimate puts the Leela Ratio at around 0.5.

A Little Mini-Update on TCEC

TCEC

Maybe

Like most TCEC posts, this one comes with many caveats. This is through a back channel, first off. Apparently, GPU is not off the table, even if it involves delaying season 13 for a while.

Again, take with a huge grain of salt.
