Hello champions and welcome to the ChessMood team!
We all are from different countries, different ages, have different professions... But one thing bounds us - the passion for chess.
Champions, we'll grow together and keep a warm relationship in our team.
Please tell a bit about yourself in this post.
Here you can find sparring partners.
You can write, for example,
"Hey guys, my name is Bob, I'm from the USA, my rating is 2000 I'm looking for a sparring partner."
Or even more specific like "I just finished the Caro-Kann course and I'm looking someone to play a friendly sparring games".
Hopefully, you'll find good friends too.
I've added around 1-hour material in the "Nightmare of Rossolimo" course.
Both are adv. sections, but this one I absolutely recommend to watch.
There are included model games, and after watching these sections, you'll have a much better understanding of the Rossolimo positions.
If I read this right, Stockfish now has a NN version. (That means it's now LC0-like). There has been no update to normal Stockfish for a while now and it appears all the work is now on the NN. When they tested it, instead of normal +2.3 rating point improvements, they got something like +90 !!!

Add NNUE evaluation
This patch ports the efficiently updatable neural network (NNUE) evaluation to Stockfish.
Both the NNUE and the classical evaluations are available, and can be used to
assign a value to a position that is later used in alpha-beta (PVS) search to find the
best move. The classical evaluation computes this value as a function of various chess
concepts, handcrafted by experts, tested and tuned using fishtest. The NNUE evaluation
computes this value with a neural network based on basic inputs. The network is optimized
and trained on the evalutions of millions of positions at moderate search depth.
The NNUE evaluation was first introduced in shogi, and ported to Stockfish afterward.
It can be evaluated efficiently on CPUs, and exploits the fact that only parts
of the neural network need to be updated after a typical chess move.
[The nodchip repository](https://github.com/nodchip/Stockfish) provides additional
tools to train and develop the NNUE networks.
This patch is the result of contributions of various authors, from various communities,
including: nodchip, ynasu87, yaneurao (initial port and NNUE authors), domschl, FireFather,
rqs, xXH4CKST3RXx, tttak, zz4032, joergoster, mstembera, nguyenpham, erbsenzaehler,
dorzechowski, and vondele.
This new evaluation needed various changes to fishtest and the corresponding infrastructure,
for which tomtor, ppigazzini, noobpwnftw, daylen, and vondele are gratefully acknowledged.
The first networks have been provided by gekkehenker and sergiovieri, with the latter
net (nn-97f742aaefcd.nnue) being the current default.
The evaluation function can be selected at run time with the `Use NNUE` (true/false) UCI option,
provided the `EvalFile` option points the the network file (depending on the GUI, with full path).
The performance of the NNUE evaluation relative to the classical evaluation depends somewhat on
the hardware, and is expected to improve quickly, but is currently on > 80 Elo on fishtest:
60000 @ 10+0.1 th 1
ELO: 92.77 +-2.1 (95%) LOS: 100.0%
Total: 60000 W: 24193 L: 8543 D: 27264 Elo +92.77
Ptnml(0-2): 609, 3850, 9708, 10948, 4885
40000 @ 20+0.2 th 8
ELO: 89.47 +-2.0 (95%) LOS: 100.0%
Total: 40000 W: 12756 L: 2677 D: 24567 Elo +89.47
Ptnml(0-2): 74, 1583, 8550, 7776, 2017
*************END OF CUT/PASTE*************
Right now it is being tested on https://tcec-chess.com/#/ and it is tearing up the field. Get ready to switch over to $1400 video cards, but there is a new sheriff in town and it is taking names and kicking butts.
Note this timeframe. Chess engines just took a giant leap. Aug 2020.
HOW I CAME ACROSS IT
Hey guys! The day I saw that Stockfish NNUE was out, I downloaded it! :) Developers claim that it has a 90 (!) ELO point deference then the previous version (Stockfish 11) I wanted to put it to test straight away! I downloaded Stockfish 11 so that I can make the engines play against each other! As I knew that it won't be easy to make the engines play each other in ChessBase (as if I wanted to, I would have to make the top moves of engines manually! I wanted a software that makes the engine's top move after a certain period of time...) I then came across this software : Arena chess GUI It is a very nice software to make engines play against one another! (here is the link to download it : http://www.playwitharena.de/) Then I loaded the engines!
I first made the engines play a 10+5 game and the result was not very much of fun.... It was a draw :(
P.S. If you want to download the software I used, then here is the link : http://www.playwitharena.de/
Hello friends. How do you study? Specifically, how do you work with the course materials?
- Do you use the PGN files? What's your process?
- Do you memorize everything? Just the key moves?
- Is there software you use that's helpful?
- Is there something very important missing from existing software that would help you study?
Sir, after the prophylactic H3, and castle, your suggestion is to go Bc7, Qd6 and attack the h2 square.
What if I go Be6 first?
If Bxe6 then we undouble our F pawns, if not, then we can activate our a8 rook first by bringing it to c8 and then go Bb8 and Qd6. What do you think about this line, sir?
Please let me know.
Champions, today we added around 1.5 hours of material in the French Defense course, covering Black's rare 3rd moves and 3...Nc6 in the advanced section.
Check it out, should be very useful not only for improving your opening.
