    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

      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.

      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.

    • @finn5568
      @finn5568 Рік тому +18

      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.

    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.

    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 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.

    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’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.

      @mastermewtwo5503 Рік тому

      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.
