cheaters: use engine to gain advantage Leko: "That's a blunder."

[@cinegraphics]

I showed the position to my engine, 1.3L turbo diesel. It wasn't strong enough.

[@ConsciousExpression]

In case anyone is wondering how an engine can miss a move like this but see how powerful it is afterwards, I'm something of an expert in chess engines. It's due to something called pruning, which is difficult to describe succinctly, but I'll try. (Edit: due to a lot of feedback I'm editing this slightly to remove some terminology that is triggering to people who are rightly pointing out that there's a technical error in this analysis. I don't think it's a very consequential error, but I want to head-off further objections that are technically correct, but IMO miss the point.) A chess engine searches for moves using something called a move tree. Basically if you pick a move, then try all the moves that result, then try all the moves that result from those moves, etc, you end up with something that looks like a tree, this is called the search tree. With each move that is tried, the search tree grows exponentially. This means no matter how fast the computer, as the search tree gets large, it becomes impossible to check every move. So to search to a greater depth (deeper into the tree) it is necessary to "prune" the tree, meaning we cut off branches that are "obviously" bad, and don't search them at all! How can a move be so obviously bad that we decide to ignore its entire branch in the tree? This is where pruning comes in. Let's say it's blacks turn, and we check a branch and it leads to a plus 3 evaluation for white (i.e. white would get a piece up). If we already found a branch that leads to an even score for black, we cut off the branch a soon as we find the moves that lead to plus three for white, and we no longer have to check anything in that branch. This technique would be fine in theory if it weren't for the fact that engines have a dirty little secret. Engines ABSOLUTELY SUCK at evaluating a board position. If this is true how can they beat the best player in the world? The answer is by looking so far ahead that the crappy board evaluation routine becomes less relevant. If we find a branch that leads to utter domination 20 moves later, it doesn't really matter that our evaluation is off by a point or two. In practice this means engines can miss great moves for a variety of reasons, but it almost certainly comes down to a bad pruning at some point, leading to the engine not even checking the move or even the branch the move is on. As I said this is difficult to explain for non programmers but hopefully this gives you the big idea. Feel free to ask questions for anything that was unclear! I love this stuff and I'd be happy to explain further.

[@jadreaidy2969]

Actually that was very well explained, well done! You are an excellent explainer of chess engine magic

[@edoson01]

That's a great explanation, thank you :)

[@ConsciousExpression]

You're both quite welcome. Here are a couple more interesting observations. Imagine if the computer could perfectly evaluate a board position (determine who is winning and by how much). Then there would be no need for a search! You could just try each move and pick the one with the best score for the current player. Every other move would lead to an "alpha beta" cutoff (a type of pruning)! So the better you order the moves, trying the best moves first, the smaller (narrower) the tree. This is why alpha zero searches far fewer moves than stockfish but still crushes stockfish. It uses a traditional search, but the neural network is much much better at evaluating a board position than stockfish, because it learned through experience rather than by simply being told that a queen is worth 9 points, rook 5, etc. In fact, alpha zero doesn't even know the point value of pieces! Or at least it never was explicitly programmed to know them. It's simply better at evaluating a given board position. Reverse engineering how alpha zero valuates a position is sadly not possible, any more than we could look at your neurons firing and figure out how you value things. We can gain some insights by looking at the neural network but it's a bit like trying to read music by looking at the grooves on a vinyl record. To really hear the music you have to play the album. This is why alpha zero makes brilliant sacrifices and plays like Tal or Morphy. Nobody ever told it about the value of material. Everything it knows about chess it learned by experience rather than preprogrammed values.

I actually found this move, I didn’t know exactly why it’s so strong, but I figured it’s the only move for black. I doubt I would have found this move in an actual game as there wouldn’t be agadmator warning me that there’s 1 brilliant move that I could make but I’m still quite proud of myself.

[@compulsoryevacuationdevice]

The queen move was also my first guess but only because agadmator told me that the pawn capture was the wrong answer. I would have taken the pawn any day of the week in that position, it's such an obvious move.

[@natknowles3153]

I found this move as well, but only because like for you, to me it seemed the only possible move for black. However, I didn't even think of the knight moves afterwards, which were genius.

Deep Rybka on 6 cpus found the move at a depth of 13 after less than 30 seconds. i7 6700K under Wine on OpenSUSE.

Stockfish8 found it immediately, also

Stockfish 7 found Qd3 in few seconds with -4.5 eval

[@andrewkiefte376]

I come back and watch this video every now and then and each time I watch that move gets even more impressive

[@Sheep.]

I found the move and was instantly like: wait, it can't be this because it doesn't achieve anything and the passed pawn will become a queen. Oh boy was I wrong.

[@anderfiori7003]

Same i found the moves but not all the prosecution of the games

[@xDMrGarrison]

If you don't see the point of it or at least part of the ideas and continuations behind it, you didn't really "find" the move. You just made a random move that happened to be the first one of a whole combination of moves and possibilities.

[@Jaxyndamere]

@@xDMrGarrison I found the moves till the knight sacrifice move. At that moment I was lost and didn't know how to continue so I guess im half genius? xd

@Don Lorenzo he needs to find the whole series of moves not just the first idiot.

[@enzorocha2977]

Not to start anything, agadmator, but I got curious and interested when you said we try if our engines might guess this invisible move, so I fired up my years-dormant Scidformac with Stockfish 9.64, setup the board similar to the pause point and let it solve for the next move. Yes, the first suggestions were Bxa6 but after a few seconds, Qd3 started popping up all through to the end of the list, with the final Qd3 having a score of +72.0! So, going with that, I was sure glad to see the engine's suggestion proven the right one once going forward with the video :)

[@JDoucette]

Thanks for your videos. Just a comment re: @7:55 "every engine I tried gives Bxh6": Stockfish 9 finds Qd3 in 6 seconds at a higher score, and at 7 seconds with winning score. (I have an 8-core machine with 6-piece EGTB with 8 GB of memory allocated for the engine.) Without the 6-piece EGTB, it finds it even faster: 1 second to even more significantly winning score (and yes, I cleared the cache and restarted the engine).

[@urex1717]

Leko's high voice drives me crazy but after seeing this, he will have my eternal respect.

[@chrisdooley6468]

Tried my two simulators and neither showed that move. But once the queen was there Aha!! Black was clearly winning lol. Not sure why it’s invisible but it’s an amazing move

[@callum5855]

I think engines disregard this line as at a first glance, the pawn will queen. However this is not so.

[@sd_jay7399]

8:36 "I haven't found an engine that can solve this position" Stockfish 13, in 2021, solves it in 5 seconds. But yeah, it's 2021.

[@mangonicusmaximus369]

maybe because they adapted the move from leko. Engines are artificial intelligence for a reason.

[@andrewc4606]

Stockfish 1.6.3 from 2010 solves this position with ease.

@Structure Agency interpret it how you wish, for your opinion means little to ne

[@rileysinclair5980]

@Structure Agency my boi, I love agadmator and would never compare him to stalin. However, he asked which chess commentator played that match, and attached a picture of a man that bore resemblance to stalin. As you see, I was not calling agadmator stalin, but I was joking by saying it about the other man

[@rileysinclair5980]

@Structure Agency totally understandable. I apologize for not making myself more clear

[@anybody314]

I saw this game on-line and Knaack - a former GDR chess champion, who was commentating it - could not understand Qd3 either on the spot, he held it for a blunder -, but later he said it is a move that marches in into chess history! Kramnik congratulated Leko as well after the match but he said, Peter shouldn't think he has already won, he (=Kramnik) can play chess as well... (Unfortunately he showed his abilities in the last game, really) I was so proud as a Hungarian that I was laughing for a week. I had tried to make engines search for the move many years ago - when the engines were much weaker than today - of course nothing was found they did not have the slightest idea about it If an Oscar prize could be given in chess for anything, I would vote for Qd3.... By the way, the Arabic subtitle is very disturbing, the last row of the board is covered.

[@hydra9267]

Kramnik pure class unlike Kasparov. And young Yasser Seirawan looks like a south american drug lord.

Yeah, kasparov uses deep theory.

Haha yeah, that made me chuckle a bit :D

[@Stop_being_younger_than_me]

I didn't see the thumbnail that well before I clicked the video, it was just in my peripheral vision.. Idk how its genius Im a 500 in blitz, 800 in classical on chess.com and I found it in 10 seconds. This just shows that genius moves aren't just for grandmasters to find, but gms need to keep making them whilst we make bad moves in between our good moves at my level. Im clearly not flexing im terrible at chess.

When someone moves their queen into a meaningless square in the middle of a complicated position you can guess you're in worse trouble than you thought you were. It's the one step sideways by the queen that's hard to see, not expecting her to move as cumbersome as a king.

[@visharadrawat977]

It's quite surprising how Kramnik and his team couldn't see the Qd3. Chess is a Game of Beauty.❤️

Here we are, five years later and Stockfish 7 finds Qd3. I think it's because I'm running AMD 7000 with 16 cores...
