15:14 The fact that the estimation bar found that this position was mate in 40 is astonishing.
It's because after queen takes queen there are only 7 pieces left and stockfish probably had access to an endgame tablebase for 7 pieces.

That mate is easy. Like you just need to take queen and all horses and then Queen mate hoping that it would not be draw by 50- move rule. Only if White played best move it would take 40 moves but no computer other than few can play best move for 40 moves straight.

Suggestion: since both engines are playing the worst moves based on standard evaluation, they are blundering mates but the opponent is not checkmating them. This is because they still evaluate under the assumption that, in the future, both will play the best moves. Instead, we could also change the evaluation algorithm, so that they do indeed assume both sides will always play the worst move possible. This way, instead of playing moves that make no progress for either side, they will actively be trying to lose, making moves that force their opponent to play something good. For example, a queen chasing a king around the board trying to force him to take her or other similar things would be hilarious
Isn't that just a bot that's really good at anti chess then?
This is beautiful. AN anti-chess wizard bot
@@bernhardbrodowsky3261 But in anti-chess ALL captures are forced, in this that would not be the case
not yet an anti chess bot tho. Captures are forced in anti, so the "stockfish" of anti chess has to set up the best forced capture chain for the opponent to be trapped in.
That's what I was hoping for. I was wondering why white didn't say her queen with check and force black to take it.
I like how this game actually looks more like an actual battle than a chess game, what with all the chaos and pawns in No-man's land, essentially sending the game full circle back to what it was originally trying to replicate.

The actual game is the intense ping-pong match that's going on in the evaluation bar.
Would be interesting to find the worst possible move, knowing that the opponent was also trying to find the worst possible move. So, not just moves that hang pieces, but moves that force the opponent to make good moves. That would actually be anti-chess, and might even be an interesting game.

You should do one where you force stockfish at its highest to play 10 worst possible moves and then try to win.

I wonder how the calculations would change if Stockfish knew the opponent would try to play the worst move too. Like hanging your Queen is bad, but if you know the opponent isn't going to take it then is there a worse move?
The strategy would be to get into a position where you force the enemy king to capture your pieces
I thought about that too, moves like Qxb5+ at 6:43 are probably the worst since they force the queen to be lost
**HORSE FIESTA INTENSIFIES**
Conceptually, making stockfish do this would be very easy, just take the evaluation function (which gets the advantage score for each board) and just add a minus sign so that it just negates the score it gets. Because the same function is used for both stockfish and its opponent, this would mean that it should also simulate the opponent wanting to do the worst possible move. This honesty sounds like the easiest way to properly make a bad version of stockfish. (There is probably more to it than that, though)
We do not know exactly what was done to stockfish in the submitted game (it having solved any version of chess is clickbait), a bad-at-being-worst version would be if it just picked the worst evaluated move from a normal version of stockfish. If a move is evidently bad enough right-of-the-bat, normal stockfish would just stop looking through how a opponent could respond, meaning it wouldn't actually know which one of the worst moves is actually the worst one.
If this game was programmed by reversing minimax into maximin, stocktish does know the opponent will try to play the worst move. I dont think it was however, it looks like he took the list of moves stockfish generated from a standard minimax or negemax algorithm and just picked the worst one
The fact that you didn't show the eval graph for this match is absolutely criminal
I find it interesting that a capture would be the worst possible move this often. I know that there are many positions where capturing would be the worst move, but I had no idea that it would come up this often.
It's ultra-surprising that the "worst move" was sometimes to take a piece. It seems like just any waiting move would generally be worse than winning material.
a lot of those cases involved hanging a more valuable piece in the process. Like using a queen to capture a defended pawn.
You will eventually run out of waiting moves.
It's because it isn't just purely the "worst move" in a vacuum. It's the "worst move given the assumption (which is incorrect in this case) that your opponent will play their best move". If you programmed it to anticipate the opponent doing the same thing then it would find a different set of worst moves, since it would want to favor outcomes that limit the opponent's bad moves. That would probably involve a lot more waiting moves rather than taking pieces.
There are multiple worst moves sometimes, in case the enemy has mate in 1.
In these cases it's quite likely a random worst move gets chosen which can also be taking a piece since it doesn't make a difference for stockfish.
It werent actually the worst moves, because most of taking was made when both sides were hanging M1, so it didnt really matter what move will the stockfish make as long as it will still be M1.

@@sqrti8825 they are talking about making the worst moves that don't show a "M" in the eval
Interestingly, it always plays the worst move considering an opponent who plays to win, like how it takes pieces to allow checkmate when the opponent won't even play it. I wonder if it's possible to program or modificate an engine to play for a loss against another one who plays for a loss, that would be insane to watch
I did not consider how painful this would be to watch. This is art.

@@joefawcett2191you literally just need to negate the evaluation function.

MrBeast: Finally a worthy opponent
😂
Dang
Lol
True
Why you everywhere
The 5:00 is one of the more interesting parts of the game imo. With the queen already hanging the absolute worst thing to do is entomb your own pieces so they cannot join in the attack on the king, while weakening your light squares to ensure the king has the maximum number of escape routes. It is weirdly instructional in a way.
I also find it funny how in the lategame, it found promoting to a knight to be frequently one of the worst moves since it removes your ability to promote to a queen
"Not like that, not like.. that"
10:04 - eval bar be like: "YEET"
I’m sadistically wondering if you did this with mismatched engines what would happen. Would the stronger engine succeed in losing more efficiently?

6:43 is a perfect example of worstfish’s flaws. If it was a person who knew they were playing a bot told to loose and they wanted to play the move that would end with themselves in a worse position they would take b4 with the queen and force the king or bishop to take it
Yes! It's playing for the position that it's hardest to win from, rather than the position that it's easiest to force a loss from.
4:30 In a meta sort of way, an even worse move would be Qd4+. The only legal response is to take the queen, so it guarantees you lose your queen.
But you would only think of that if you weren't going purely by the evaluation the way a computer does, but also taking account of the fact that your opponent will avoid giving themselves an advantage as long as it's legal to do so.
I like the part when Levi explains that stockfish is playing the worst possible move instead of the best possible move
LITERALLY the worst possible move
Im unclear, is stockfish playin the best possible move here? Video should make it obvious
I like the part where he shows the next 13 moves each side can make after every single move
I had Mythbusters flashback.
This is an interesting idea but it would be better if stockfish could calculate knowing the opponent will choose the worst move himself!
This is what I was thinking!
Agreed, I think that the game would look quite different if both sides were trying to prevent the opponent from having any losing moves.
Ooh
I had the same idea but you explained it better than me. I was thinking to make it play to try to force the opponent to win with checkmate, if that's even possible
Yes there were times where white could force the black king to take it and same with the black Queen and white king
The bar is a rollercoaster
I could see this being a fun human game, where each player adds up their advantage/disadvantage for each move over the course of a set number of moves, and whoever has the cumulative worst total at the end wins.
I'd like to see an AI that chooses the most losing move with the assumption that the opponent is trying to lose first. They'd probably find ways to compel the opponent to mate them, such as by checking the opponent where their only valid move is to mate back
E
Or they would play the longest game ever (assuming that they would avoid position repetition)
"I'm not going to remind you every turn it's playing the worst move possible every turn" proceeds to do it every over turn
well he technically wasn't lying; he did indeed not do it every turn

I thought for a second for sure it was a 200 vs 200 elo

The fact that Levy can call every position with the pieces and with extreme accuracy it’s fascinating. If you watch a bit after that he does it all again but faster. My god this man is disciplined.
It is interesting how all the pieces avoid the center proving it is where you want to be.
There should be another edition of this where stockfish knows the opponent is going to pick the worst response, and picks the worst move with that in mind.
Instead of attempting to blunder the game assuming the opponent is going to be reasonable, each side will be trying to force the opponent to win against their will.
I think it can be even better: Currently it chooses the move that gives the opponent the biggest advantage, but the advantage is calculated given the opponent's best move. We should program stockfish to choose the worst move given that the opponent *also* plays the worst move. e.g. a great move would be to *force* the opponent to take a piece or get closer to mating you.

As a mathematician, I can't call this having "solved" anti-chess. We don't say Stockfish playing well is having solved regular chess.
Solving a game is much more of a claim than being able to do well at it. It is knowing the entire game front to back. It is knowing, from the beginning, how the game will end if both players play optimally. It is a game between 2 players/bots that can see infinite moves into the future. This is not it.
