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.

i was boutta comment this

I was going to comment this!

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.

16:18 mate in 45

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.

Antichess is already a variant on Lichess. The premise is that if you CAN capture you MUST capture. First player to run out of moves wins.

😀

@@rage2904 well then we call it something else

chess needs a version where you gain points for losing each piece and you win by getting checkmated

As a kid I used to play poddavki with my father, it was basically anti-checkers, trying to be first to give all the pieces away

I guess that was the worst possible move by Levy 😁

When a chess game is that bad, it's hard to not mention it. At least it went faster than my chess games, at one move every 2 minutes.

​@@drenz1523 bro doesn't know how 50 move rule works

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.

​@@whoknows1520r/woooosh

​@@aashd9245get out.

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

They'd call it Magnusfish.

If you play the worst possible moves against a normal opponent you are checkmated in 2 moves

any player can win against worstfish in 3 moves since it enables you to make fools mate

I say we post Magnus-Stockfish under each and every video until it happens!

It would be fools mate

That happens in normal games too! I’ve seen some wacky back and forth bars lol

@@devdecker7812 skill issue

@@aspect359 not gonna happen as much with people though, stockfish is a computer and you can guarantee each move will do that if it’s programmed to

@@aspect359 I’m rated 712 and still going up I’m not too bad better than the average person right now

​@@devdecker7812 skill issue

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.

It doesn't seem to know the opponent wants the same thing though. It should play to force the opponent to take its queen

@@lukasg4807 would literally take an entire reprogramming of everything thats been done so far

@@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.

jokes on you I set that up without even trying

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

it would just be a draw

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

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.

True

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
