at 3:08, the knight on b7 doesn't have to go back to c5, it can also go to d6 right? Which will then fork the two rooks, and the queen can't capture it because the pawn is protecting it? And there is no other piece which can trade off the knight safely... what am I missing here? Since two engines and Agad himself can't have missed something this obvious edit: for those of you who might not be as good at the game such as myself, I went ahead and loaded it on an engine, to see what exactly the computer would play as black to this. It is the brilliant knight captures pawn on e5, and when I captured one of the rooks (it didn't really matter), the computer plays knight captures knight on f3 with check. You either capture back and completely mess up the defense for the king, or you move your king and lose your own rook. And capturing back is horrible enough for the engine to give it a score (idk what you call that bar which gauges which side is winning) of -2.5 or something. Pretty interesting (I am like 800 elo btw, sorry if any higher rated player gets a stroke reading this lol :p)

The incredible thing is that 2 years later, Stockfish still doesn't understand the queen sacrifice. It will at first claim the position is lost for *white*, and then it will say the position is drawn. Stockfish gives many "drawing" lines by black. However, if you actually play out the moves it will realize that white is in fact winning in all of them!

[@eriklarsen9118]

Put into Stockfish on Lichess right before queen sac, Stockfish recommends Qxb4 with an evaluation of 0.0. Obviously this is not the same stockfish as in the game so perhaps improved or stockfish in the game actually was anticipating the queen sac but not worried about it. Second move by Stockfish today is Qxd4 with essentially same evaluation of -0.1. Next best move is Nf6+ but considered losing with eval of -1.5. Continuing stockfish evaluation: After bishop capture, axb4 recommended as in the game The interesting things happen when the dance of the engines stops using white's pawn push to f4; Stockfish does not recommend this move at all in that position and has the game evaluated at 0.0. AFTER the f4 pawn push Stockfish churns for a while and then decides it is +2.1 so now totally winning for white. That was the move Stockfish did not see coming! After that it is a clear win for white according to the engine.

This demonstrates why I absolutely love the engine matches of Stockfish and Leela. When a human player plays a brilliant move like a queen sacrifice in what seems like a normal position, you can pull out the engine and go "the more precise refutation of this idea was to go X to Y followed by this and that" but when even the engine can't find the idea, what do you do then? You can only stare in sheer disbelief and awe as Leela converts a seemingly terrible move into a stunning victory without either player making a mistake the whole way.

@7:41"You are doing well, don't mess it up!"

[@gregorymorse8423]

Dance of the engines is just seeing lots of winning lines if the opponent makes a mistake. But the 3 move repetition limits the mistake offerings. Obviously engine vs. engine makes mistakes extremely unlikely. Finally it procedes down a line slightly less winning. Remember engines dont assume best play by the opponent, they consider all opponent moves. So in certain circumstances this can happen. Someone mentioned it could buy time using these occassions but AFAIK this is not done yet anywhere. It's a narrow special case really where it's possible. Redundant moves are mostly common in some parts of engine vs. engine games because of near perfect play leading to positions where waiting and hoping for a mistake by the opponent is the best idea until it's not because it stops leading to a win but to a draw

The Stockfish level on lichess are intentionally designed to make mistakes to keep the games interesting. They aren't great at making "human-like" mistakes, but it's useless to use them to analyze the playing style of full-strength SF.

[@harleykf1]

On the contrary, I find those levels just give pawns away. Unfortunately for me lichess level 7 often gives away poisoned pawns. Once it sacced its queen leela style and checkmated me with knights and bishops.

[@GeraldM_inNC]

@@harleykf1 I give you credit for daring Level 7 -- I'm sticking to Level 5 until (if ever) I can get 50% wins or draws. I only play white. Even on Level 5 it's just ferocious, attacks relentlessly and always plays to win. Most of my wins come because it has pushed a drawn position and tried to force a win out of it. But I think Agadmator's videos are helping me, my percentage of wins and draws has gone up quite a bit (from almost never) over the months I've been watching his videos.

[@GeraldM_inNC]

@@harleykf1 One thing that bothers me about Level 5 Lichess is that now and then Stockfish just pushes all of its pawns like Pickett's Charge, not attempting to castle or to develop its pieces.

[@AlcyonEldara]

The engines have the "feeling" that they have an advantage but they cannot see the winning path yet. In some positions, you need to give up some of your advantage to progress, and the engines don't have any reasons to play it ASAP and they don't want to maximize their advantage, so they don't mind to "shuffle", like "as if" they are waiting for a blunder. Of course, when the 3-fold repetitions or the 50 moves rule kicks in, the engines play something different, and progress can be made. Lc0's dev created a new patch "MLH", but without going into full details, it reduces the "dance of the engines". For SF, this is a lot more difficult to patch, and there isn't any reason to do so (they want the strongest engine, this kind of behavior doesn't reduce SF's strength).

[@DanielGomes-sw2fd]

SF engages in "high-level shuffling" as well but it is mitigated by human code that punishes shuffling.

This easily allowed white to have a nice knight outpost on f6 and a bishop outpost on h6 which was very decisive.

Jesus what a game this was!!! Queen sacrifice for mate in 114 moves force mate 😂😂

[@DjVortex-w]

That queen sacrifice might be something that traditional bruteforce/AB engines just cannot see, because they can't look far enough to see whether it works or not, and the positional knowledge needed to know that it works is too much for this kind of engine (because these engines are based on searching as many billions of moves as possible, which precludes them from slow deep positional analysis). Only a neural network based engine like Leela can have the positional "understanding" to see that the sacrifice will work in the long run, even when it cannot read even nearly as far ahead as Stockfish can. I think this really shows the difference between traditional techniques and neural network techniques.

Let's go through it step-by-step until the endgame. If you move there, black knxe5. Best response for white is Rookxd4 (if Knxe5 again, black queen captures undefended first knight you moved and it's downhill from there) After rook takes, best move for black is knightxf3 with check Best move for white is to recapture with the pawn from g2 Queen c5 is best response from black, hitting the now unprotected rook, and if knxe8, queen wont be attacked. (White can't respond by moving the rook and capturing the undefended bishop on h4, because then the queen could just capture the knight, and after rook f4 best move and black defends, white has absolutely nothing and black has pushing pawn up to e5, attacking the rook and opening up the white diagonal for your bishop in which the white queen is placed.) So white has to bring the other rook to e4 Black responds with f6 getting the bishop out of the way and also attacking the rook on e4 with the black queen White Queen would have to go to d2 to defend it Black queen to h5, this opens up the rook to be attacking the lightsquared bishop on c4 being defended by two rooks to its right now, and also to attack the dark square bishop on h6 White queen has to go to f4 to get behind the rooks defending the bishop on c4, while still defending the bishop.on h6 After blacks darks squared bishop on f6 bxRd4 And the other white rook on e4 recaptures to d4 You have to be careful of white queen capturing undefended pawn on f7 which would assuredly lead to a forced checkmate. Black pushes pawn to g5 to defend f7 by a discovery with their queen White queen takes up f6 Black queen has to go g6 offering a trade White instead would obviously take the undefended pawn on g5 Black wants to trade material now so rook captures bishop c4 White captures back with knight c4 Black has a nice square on d5 for the knight, defened by the pawn on e6 and attacking whites queen White is forced to trade queens on g6 Black h pawn would capture White Knight to E3 to double attack the knight, Blacks dark bishop to c6 defending White has nothing to do especially compared to blacks powerful knight so they would trade Bishop recaptures to d5 White wouldn't want to give up the rook this lategame having doubled pawns so first bishop to f6 to prevent the king from coming in, which would at that point be more important than protecting the doubled pawn and letting black get it's rook in on the C-file Black bxf3 White Rook h4 trying to checkmate Black bishop to h5 defending And after white rook to a4 attacking blacks pawn still on a7 and blacks rook to a8 defending it, theres nothing to do for both sides but move the king up in an opposite bishop and rook endgame where stockfish would be ahead a pawn. -- I think agadmator is rubbing off on me

You can really see the similarities between leela and alpha zero, both love sacrificing pieces if it means paralysing your opponent movement. And while i am a big fan of A0's play style, i have to give the 'flare' award to leela in this game. A0 loves to sacrifice pawns but leela took it to the next level with a queen sacrifice with no *immediate* return on investment which is something i haven't quite seen A0 do against stockfish (correct me if i'm wrong), Also while i've seen A0 restrict the enemy movement a lot, i've never quite seen stockfish have to repeat so many moves due to the sheer lack of choice. I'd love to see a match between A0 and Leela, i think leela's designed was based off of A0 so could you argue that this would be a match between the Student and the Master? Or maybe even between a father and his daughter xd

What version of stockfish is this?

[@gunnerjohnson5445]

I made up a rule to get more interesting practise games: "If u get two pieces for the queen, u have to give it up." (A long time ago I did this) But Morphy and Tal did things like this, so I had to do it. (My rating is only 1725 so don't worry) Anyway, besides follow ups, which are great u must consider the following: "After this you must be consolidated." "1. You go after the opponents queen." "2.You go after rooks " Basic stuff and if u are completely solid it is going to work out. So it's a good training strategy bcoz you have to find the best moves. And often u have to defend. Like Fishers opponent said: "How many ppl can really defend?" What happened to Stockfish here is what you will find in your games as well, if all is defended. You have options, your opponent dont. Typical way of ending such a game is queening your pawns.

The rule doesn’t always work. As always it depends on the position

[@gm2407]

I think the "dance of the engines" is LcZ giving the oponent a chance to try something else and blunder before LcZ decided to go to the next plan as Stockfish had nothing else it would do in that situation and would be willing to draw.

What happens if the starting mooves are not predetermined ? Was there ever such an occasion ? #suggestion

How do I get better at chess, I have been playing for 2 years, but am rated 1200 blitz. I have done tons of tactics training, and consistently get 18-22 puzzles on puzzle rush, but I don't seem to be improving. I know basic endgames and openings. Is this normal or am I just intellectually disabled

[@vymahesh]

At 10:49 after the white king takes the rook, why doesn't black take the knight at g5 with the king? Doesn't it protect the rook at f4?

Thanks for Sharing Aaron's song. Very talented guy! Beautiful song...

[@samkachar]

What is that noise I heard toward the end? I've been hearing that sound alot lately during podcasts. It happened twice during this podcast.

[@craxanshards3139]

I was wondering as well

[@vinith8669]

It's a twitch sound: When someone donates with bits. Idk maybe he was streaming or had a stream open

[@robologo]

It's cool that they can sacrifice because they know exactly what will happen after. I imagine stockfish's eval bar going from -7 to -3 to -1
