I Invented A Chess Opening. It Beat Stockfish. 

she says the engine made a mistake but how and it is in depth 42??? i really don't believe her at all this opening is like "if you don't know what you are doing then your opponent won't know what you are doing"

@@mohammedalkhodairy I believe the engine is on depth 14. She is probably using a stronger engine to determine if stockfish made a mistake. She is just making the point that it is good to get your opponent out of theory and we are doing that with this opening and the opening is not bad.

She's nearly a GM and plays her mom who is a GM all the time. Sorry, Muhammed, I trust her way more then you. Plus I believe the more opening concepts you understand, the more positions you can understand mid-late game outside of the opening.

@@hatefulcrab8515 meh alright she is very good but you gotta admit the opening is not that great for advanced player

@@hatefulcrab8515 not even nearly an IM

😂😂👌🏾

I think she likes cows though, so she might not want a meat-based name

😂😅

@@sashaboydcom ah yes, you’re right, she didn’t like the steak variation for this reason . Hmmmm, is there a noun for an old cow? Heifer is a younger cow but I don’t know of an equivalent for older. Maybe old daisy variation instead?!

Bro that was a good pawn

And also to see how Stockfish holds up with the cow opening as black

gotta see if higher depth stockfish would make different mooves

Your comment really rooks. 🤟

What a knightmare of a comment section is this!

Took me a second but I get it haha... Nice 😇🙏

ya

What is official opening?

​@@ArthurvanH0udt Wow. That's interesting. It's now almost impossible to make meaningful innovation in the openings.

@@archivist17 It is. Everything will be a variation of an existing opening. I did find some room in the QPO and invented the Grasshopper opening. It's almost a London variation but I can make a case that it stands on its own - and it also technically isn't a London. So yes, it is still possible to innovate. And to be fair, calling all 1.e3 openings a Van 't Kruijs is giving the Dutch man a bit too much credit. In my book, this cow opening also stands on its own.

​@@ralphzoontjens agreed, this isnt the Van't Krujis. Opening explorers will give that label to any e3 opening but this doesnt have to always be the case--e4 can become a multitude of things of course so the Cow can definitely be its own unique opening

I agree. It's really fun to see how often the opposite sacrifies it's bishop, confused by the position of knight. 😂

yeah so far every person I played just pushes every pawn and end up losing them to the knights

It’s fun seeing no one know how to react. Since it’s not tested there’s no perfect lines either. I’m only playing like 1400ish so quite different from higher elo games I’m sure.

I won a 5 game cow opening streak, and then on the sixth game, black mirrored my opening and then sent me a "mooo" in chat. I lost, but it was worth the laugh.

@@bonolio Ha ha awesome!

If Someone tries this on Me; what's a good line to refute?

We could call the refutation the Ground Beef Defense

I tried SF 15.1 playing with SF 15.1, 30 seconds time to think 12 games with white (2 wins, 6 draws, 4 loses) 12 games with black (0 wins, 7 draws, 5 loses)

that's just because stockfish doesn't have enough experience. Bet you it can beat it now.@@ondra_vro

I think they have disowned her after realising the disgrace to the chess community their daughter has brought them!

Lol

they wanted to call this the donkey opening, but their daughther likes cows that smell flowers in the morning with little birds flying around and pig dancing with gooses

Her dad invented the Bellon gambit!

Her dad said he would at least try it. Her mom said "oh anna....."

The exquisite opening for prof. Chessplayers! 🥰

Pawn to A5!

Leather jacket variation

A4 A5 variation

Cringe

I would’ve played it differently

Also her dad reacting, too. Just to see if he says "you play like this?" again.

"hmm, that's an interesting move"

Ok she did it

Mom doesn't like it lol

What is your ELO?

@@bingley_music Losing 35% does not sound bad, unless you also draw 50% :D

And how many draws? If you’re winning 60% to 65% vs people at your level with this opening, you’re already a beast!

I think this is it. It's a fun opening, and I get to see/play positions I don't normally see.

Black Cow? Black Cow Defense?

Sure u did

sure you did

Isn’t it too passive for white? I don’t think it’s too bad

Yes and Ferdinand was a bull

Enabling multiple lines reduces the engine strength **significantly** if the depth is unlimited (and involving a human in the process of choosing a line probably reduces it even more).

@@-zelda- Any proofs on the "significantly" part? I remember watching some tournament with Magnus and there is a guy that runs a site with either supercomputer or just a strong PC analysis, it runs in two modes, one is usual single line, and second PC one runs in multiple PV, that calculates every (!) move, and even when calculating 20-30 variations the second pc gave the same best moves every time that I looked.

​@@_APV_ The data can be found in the Stockfish wiki > Useful data. In general, it shows that enabling a 2nd line has a -100 elo impact and every addicional line reduces it by another 50 elo. Enabling multipv means that resources are shared between lines so you get a wider search but you also get a less deep one. The site you're thinking of is Sesse. It is expected for the main analysis and multipv to agree on most moves, just as Stockfish agrees with other weak engines it competes with on which is the best move most of the time. But most of the time is not _all_ the time, and in chess you have to choose a single move to play and sometimes there are some moves that even if they seem close in evaluation compared to other suboptimal moves they are the difference between winning or not in the long term. In the site, you can currently see that for example in the "analysis after 16… a5", the main analysis evaluation is -0.51 and the best move is 17. Nd2 while in multipv the evaluation is -0.38 and top move is 17. Bd2.
