For an interested Chess player, that has already asked in vain around 15 times in the CCCC chat, where is the PGN of all the stage 1 games?

Thanks for diggin' out that link. If someone is interested I will clean it up (e.g. 17 pgn headers are not necessary), add round tag numbers
and remove the pv comment for readability.

I wonder why they hadn't added the round tag number automatically?
BTW one mod said today they are thinking about a change from 'Arena' as GUI
to 'another solution'. (Arena is wellknown for problems and unterminated games)

Does someone still have the final table of stage 1
and how they counted the unterminated games?

If anyone with CuteChess experience wants to give us a hand, I'd love it! Just reach out to me at chesscom at gmail.

I'm looking to put together an easy email list of engine developers for the CCC so I can communicate with them about changes, receive updates, etc. I'm missing contact info for:

Crafty (I actually have it, but worried it will go to SPAM and can't include "Crafty" in every subject line )

Gull (maybe no longer being updated, so doesn't matter)

Ivanhoe (maybe no longer being updated, so doesn't matter)

Laser

Nemorino

Nirvana

Vajolet

If any of you are interested, please email me! chesscom &t gmail

Thanks!

All cleaned up and ready, but there is at least one game missing:

Rd 46. Laser-LC0 is not there!

Also Rd. 28 Crafty - Laser has only two unterminated games, while I thought the rules
require a replay until there is a result.
There was already a predecence for this, as Ivanhoe - LC0 was started three times
until there was a result.

So we have 569 games (including 19 unterminated games) = 550 (should be 552 terminated ones, 46*12)

Lc0 now has a training run using tablebase rescoring for training, rather soon we should be able to see improvements in endgame play from this.

And you still keep "0" in the name, what a joke...

Yes. They do that, to annoy you. And it's good.

But that's a side experiment, right?? The main nets better continue to be "0".

I see it's test30 that has TB cheating. If that goes over to the main net, it'll be a ridiculous decision totally against the written first goal of the Lc0 project.

I first goal of Lco to follow A0 was almost complete since 10xxxx series.( Simulation tests showed that Leela was very close to A0, within 50 elo level, A0 and SF 8 were history of 1 year ago anyway)

Second goal is to fight for No 1 and now she is among big 3 level in CCCC.

Series of 20xxx , and 30xxxx networks are aiming to be No 1. (Leela should be no 1 in 2019)

I disagree.

A0 was known to scale well and to be weak at blitz.
I read that it is the opposite with LC0 so LC0 has clearly something different from A0.

Edit:
I also disagree that Leela should be number 1 in 2019.
Other programs also improve and in any case I cannot define Leela to be number 1 based on unequal hardware competition.

Edit 2:I also disagree that now leela is among the big 3 level in CCCC.

I see
1)Stockfish 11/15
2)Houdini 10/15
3)Komodo 9/15
4)Lc0 9.5/16

I guess stockfish houdini and komodo are the big 3 and so far lc0 is lucky.

How can I download these CCC games in .pgn?

Disallowing update between stages will just show a similar result from stage 1.
