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
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.

My favorite part was when Levy said that he wasn't going to reiterate that this was the worst possible move every move then proceeded to reiterate that this was the worst possible move every move.
well actually, with 7 or less pieces on the board its mathmatically solved so stockfish just has to check the database and run the position, that means and position with 7 or less pieces has been solved including this one and it just memorizes the forced mates.
For anyone wondering the game had these White - 0 Brilliant - 0 Great - 1 Best - 2 Excellent - 0 Good - 1 Book - 0 Inaccuracy - 2 Mistakes - 76 Misses - 30 Blunders Black - 0 Brilliant - 0 Great - 1 Best - 1 Excellent - 0 Good - 1 Book - 2 Inaccuracy - 1 Mistake - 64 Miss - 42 Blunders
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.
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.
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?
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
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.
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.
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.
@@joefawcett2191 Not necessarily. If you negate all leaf values from the search(i.e. a mate in the future gets counted as a loss, being mated counts as a win, winning a queen is losing, etc.) then all you really need to change is the evaluation function.
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
Amazing content as always. But... is worth noting 1. Stockfish strength relies on in great measure to its aggressive pruning. Avoiding the analysis of bad moves (supposed bad moves) from both sides. To play worse that pruning should be reversed. 2. Chess engines evaluate the position supposing that the opponent will make the best move... it should be rewritten to suppose the other side will make the worst move. 3. I guess the "principles", the parameters the software uses to evaluate a position (a leaf, a position that will not be "advanced) should be rewritten too. It should be reprogrammed to lose, not to play the worst he can find. I am writing this supposing that you do not know about decision /game trees (I mean in a programming sense, in the chess... it is just what you mean when you say "calculate a move"). It is very probable that you know what I am saying far better than me... in that case my apologies. Forgive my English.
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
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
Levy: “i am not going to remind you every move that this is the WORST possible move” *continues to say every move that this is the worst possible move*
This should be a part of game review along with Great moves and Brilliant moves, like a triple question mark that says you played the worst possible move in that position.
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.
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.
Took me until the very end of the video to figure out the premise that Stockfish was LITERALLY programmed to make the worst move possible!. Really wish you'd said it 140 more times so that I hadn't missed that :(
you know there's a problem with this, when calculating the worst move the engines are still assuming that the opponent will play the best move he's given, it would be perfectly bad if the engine calculated according to the knowledge that opponent will play the worst move he's given
Levy: I'm not gonna remind you that stockfish will play the worst possible move Also Levy after every move : bEcAuSe iT's PrOhRaMeD tO pLaY tHe WoRsT pOsSiBlE mOvE
It would be really cool to see if the objective was TO LOSE and not to just make the worst move each move. That way Stockfish would find a way to force the opponent to take his pieces and possibly even a way to force the opponent to checkmate. Would be interesting
It would be even more interesting if they both stockfish know that the opponent will play the worst move (it doesn't seem like that now, for example in the opening Qe1 with the intent of Qh4 to lose the queen wouldn't make sense)
@@dasMoschustier impossible in the sense that "play the worst move possible on each turn" with the goal of "losing the game" is not compatible. In this video, they just had to play the objectively worst move on each turn, they weren't trying to lose. Otherwise it is like saying, I am trying to reach somewhere by walking away from there.
I’ve been wondering about this for so long. It seems like ability to checkmate was inversely proportional to material advantage. In the beginning black was hanging mate over and over, but when white took some pieces it started to be the other way around.
Playing moves that give the biggest advantage to the opponent is really interesting! I wonder if you can get someone to program stockfish try and force itself into checkmate, rather than just offer it.
I'm actually unsure if a player can checkmate themself in Chess. Maybe a few very specific positions where a queen has to block a check that just happens to be checkmate, moreso probably capture a checking knight? Generally, the other player must manually make the final move as you can't move a king into a position to be in check.
@@mastermewtwo5503 Yeah it'd be really interesting, almost every 5 or less piece end game could not result in a forced checkmate on yourself. But perhaps tooling a bot for that purpose would yield a really interesting game. Or possibly you could set up a non-FIDE rule set, wherein if a player makes a move that repeats a position for the third time they lose. Thus I think you could force yourself into checkmate without the 50 move rule in play. though the games would be infinite.

This is because they still evaluate under the assumption that, in the future, both will play the best moves.

Levy: “i am not going to remind you every move that this is the WORST possible move”
*continues to say every move that this is the worst possible move*
This should be a part of game review along with Great moves and Brilliant moves, like a triple question mark that says you played the worst possible move in that position.
(?!?) Throw
Ever heard of a.......blunder?
@@Shilpa_Kujur not every blunder is the worst possible move he’s saying a blunder so bad you couldn’t make a move that was worse
@@boaz5898 That I get, but the triple question mark is literally the symbol of a blunder.
@@Shilpa_Kujur no, the symbol of blunder is double question mark
"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 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.
Antichess is already a thing, and I hear it's already been solved
@@lightlysal is there any videos on antichess
@@lightlysal This is not the same as antichess. Because in antichess capturing is compulsory and there are a few more special rules.
@@yetischwein oh u right u right
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.
Took me until the very end of the video to figure out the premise that Stockfish was LITERALLY programmed to make the worst move possible!. Really wish you'd said it 140 more times so that I hadn't missed that :(

My thoughts exactly
you know there's a problem with this, when calculating the worst move the engines are still assuming that the opponent will play the best move he's given, it would be perfectly bad if the engine calculated according to the knowledge that opponent will play the worst move he's given
Right? Like anti forcing moves, like checks that give up material
Levy: I'm not gonna remind you that stockfish will play the worst possible move

His commentary made this video unbearable
i would love a worstfish+martin vs worstfish+martin each one taking turns playing a move.
It would be really cool to see if the objective was TO LOSE and not to just make the worst move each move. That way Stockfish would find a way to force the opponent to take his pieces and possibly even a way to force the opponent to checkmate. Would be interesting
this is what my brain cells are doing when I need them to work
“I think drunk stockfish when programmed to lose, just really likes ponies.” Dude that line made me laugh hysterically.
Another great example of how chess played perfectly is a draw.
But white got checkmated wdym...
@@TheChosenOne20100 the bots were programmed to end the game in endgame so that a draw doesnt happen
@@TheChosenOne20100 yes but he said that if they continued to play the worst moves it would be adraw obviously
15:14 can we just talk about the stockfish normal version found a mate in 40 for black?
Dam 🦫
Init don't know how he didn't mention that
Mate in 40? I can barely solve Mate in 4 😭😭
Whith all the knight promotions the board basically turned into Mongolia
I’m already dying after the queen tries to hang itself but black just moves it’s king all throughout the center 😂
17:07 should’ve played Qe6 stalemate if stockfish was doing the worst moves
It would be even more interesting if they both stockfish know that the opponent will play the worst move (it doesn't seem like that now, for example in the opening Qe1 with the intent of Qh4 to lose the queen wouldn't make sense)
I though this would be the rule
@@pinadesecada2585 That's impossible.
@@jake8217 It's not impossible. Although it would not change a whole lot.
@@dasMoschustierit would actually change a lot
@@dasMoschustier impossible in the sense that "play the worst move possible on each turn" with the goal of "losing the game" is not compatible. In this video, they just had to play the objectively worst move on each turn, they weren't trying to lose. Otherwise it is like saying, I am trying to reach somewhere by walking away from there.

Were you imitating one of the horses? Or was there really a spider on your wall? 🤔
The eval bar in the whole video: 📈📉📈📉📈📉
I love how Levi skill-fully ignores how much of an existential crisis the eval is having.
In a high level game the eval bar is unmoving, in this it is like banging a child against 2 walls
@@jnmarshmello2728 why would you bang a child?
It'd be great to see a version of this where the goal is to force the opponent to checkmate your king and take your pieces.
antichess and self-mate puzzles are the closest you can get to that
14:32 I love how he calmly says “Oh, there is a spider on my wall.”
I’ve been wondering about this for so long.
It seems like ability to checkmate was inversely proportional to material advantage. In the beginning black was hanging mate over and over, but when white took some pieces it started to be the other way around.
Yeah. I found this pattern too and now I give away at least 2 pieces before move 15.
Levy is like an alternate universe Josh Weissman who got really into chess instead of cooking.

I feel like knowing the worst move each turn is just as valuable as knowing what exactly to do each turn.
It sounds like the most useless superpower
This could become a chess variant
Chess but you have to lose and check when ever you can
The fact that you didn't show the eval graph for this match is absolutely criminal
Playing moves that give the biggest advantage to the opponent is really interesting! I wonder if you can get someone to program stockfish try and force itself into checkmate, rather than just offer it.
I was really hoping to see one side force the other to checkmate 😅
I'm actually unsure if a player can checkmate themself in Chess. Maybe a few very specific positions where a queen has to block a check that just happens to be checkmate, moreso probably capture a checking knight? Generally, the other player must manually make the final move as you can't move a king into a position to be in check.
@@mastermewtwo5503 Yeah it'd be really interesting, almost every 5 or less piece end game could not result in a forced checkmate on yourself. But perhaps tooling a bot for that purpose would yield a really interesting game. Or possibly you could set up a non-FIDE rule set, wherein if a player makes a move that repeats a position for the third time they lose. Thus I think you could force yourself into checkmate without the 50 move rule in play. though the games would be infinite.
Martin is like "finally a worthy opponent"
