[@ethanofalltrades8622]

@@RGC_animation The most interesting thing I think is how the Chess 100 AI seems to have a lot more awareness, but it chooses to make bad moves on purpose. It's most clear in the opening that black knows how to put it's pieces in good places. But on move 6 (pawn to d5), it suddenly makes a terrible move for no benefit and leaves a center square pawn unprotected and under attack. I think the chess 100 AI is a single algorithm for all levels, and they added a lot of mistakes to bring it down to level 1. This makes sense for a master chess program because you want the AI, even on level 1, to play like a human and use positional strategy and common openings, but it also needs to make enough mistakes that the human player has a chance. Another interesting thing is how CB is looking 4 moves ahead, but only for the best piece count. It doesn't have awareness of winning the game, so it just continues to take pieces until it can't anymore. It also doesn't have awareness of situations it must avoid, such as stalemate (but only if they are winning). I suspect that almost all games will end in stalemate. My biggest takeaway here was honestly how much is missing from a chess AI that can see 4 moves ahead, but nothing else. For anyone who's interested, here's the whole game in pgn: 1. h4 d6 2. b4 h6 3.

Dude your algorithm could have beaten Level 1 IF you had implemented check and checkmate.

If you were to add that checkmate equals like 10000 points then your algorithm could easily beat level 1 even more if you increase the depth

The AI also didn't seem to get any penalty for sacrificing the king nor reward for a checkmate. For example: around 9:25 it misses an easy mate in two, despite supposedly looking four moves ahead, meaning it must have prioritized capturing pawns over the checkmate, in turn letting the opposing AI play into a stalemate.

[@mementomori5580]

The biggest Problem with the AI is that it has the wrong goal. The AI tries to take a many pieces as possible while completely ignoring the not only the positioning, but also the King! the actual goal should be to place the enemy King into a checkmate. The other pieces are just a means to the end, but for the final goal they're all irrelevant. And quick fix might be to give the King a very high number so that putting the king in a checkmate would be a very valuable move to consider. In your value appointment for the pieces, you completely ignored the King, so I don't know wether or not it has any value and how high this value is. Try setting it to something like 40 (sum of value of all other pieces + 1) or so. That should make the AI try to go after the king much more. Of course, this could also backfire if it makes bad moves and sacrifices all of its pieces just to try to get to the king which it might never reach...

[@rompevuevitos222]

Well, the AI will probably learn that eventually, it wins once it captures the king so it will try to acomplish the same result once it figures that it can do that to win

[@mementomori5580]

How will it learn that? It's not a learning/evolving algorithm. If it were, it would play differently every iteration even if the enemy would play the same. But it doesn't, because the Algorithm that he uses simply doesn't support that kind of changing behaviour.

[@mementomori5580]

yeah, based on the minimax Algorithm he's using it should basically end up with the exakt same game with the only difference that, at the end, it will go for the king a little more if it has a chance (especially if there is a guaranteed checkmate, which often is the case... so unfortunately, it often takes more than just 4 steps to get to the guaranteed checkmate).

[@bestvitalic]

Wow, interesting concept! Since for you to be able to control squares, it would automatically be careful with pieces positioning and also material as well, since it wouldn't be able to control as much if it gives pieces away, however I think it would be possible to "cheat" the crap out of it, if you're careful enough to lock all your pieces and give all the mobility to your opponent, then you could then capture some of the AI pieces in a way that he would think he was still in advantage, but suddenly you would unlock all your pieces and exchange the remaining pieces, simplifying to an easy to win end game, but I really think it worth a try! :d

[@marouaneh175]

That's what chess AI do, given a position, they look at every piece and give it a score based on a heuristic, and compare the total scores for black and white. Different heuristics give rise to different styles. A checkmate is affected infinity, to make the AI sacrifice pieces to win the game if possible, or to avoid being checkmated. Specific score values differ from one AI to another, but they follow the same general ranking of importance more or less. A passed pawn is worth more than a pawn that hasn't moved, a pawn late game is worth more than a pawn in the early game, a double pawn is not worth as much, a knight's worth depends on its position, if there are too many pawns a knight is worth more than bishop, and vice versa, a piece's worth is affected by the number of peaces attacking it or defending it, and on whether it's pinned, etc. In the opening, the AI is usually given bonus score for castling ASAP and for developing pieces, some AI have an opening hand book that they pick the few first moves from, others like Stockfish compute from move 1.

[@XxConsolePlayerXx]

I hope that this comment can help you building the AI: in the scripting part you forgot some rules: the rule of castling, which "consists of moving the king two squares towards a rook on the player's first rank, then moving the rook to the square over which the king crossed. Castling may only be done if the king has never moved, the rook involved has never moved, the squares between the king and the rook involved are unoccupied, the king is not in check, and the king does not cross over or end on a square in which it would be in check." (quote from Wikipedia). Other rules are: when the king is in check, he has to move or a piece must defend him, and this means that king can't be captured, infact he doesn't have any "value"; when a piece is "pinned", "a situation brought on by an attacking piece in which a defending piece cannot move" (quote from Wikipedia) without exposing the king and therefore putting him in check. Other two rules are that pawns which reach the last rank can be promoted in any other pieces and the infamous en-passant rule that many chess beginners don't now about (some of them complain that it's a "bug" when they see it the first time ahahahaha). Last but no least, it's missing the rules of checkmate and stalemate (you noticed that when confronting the level 1), that are 2 ways that a game can end. The third way is resigning, which isn't necessary. As you stated in the end of the video, the minimax algorithm also takes in consideration many more variables when exstablishing the value of a position: i. e. if a position leads to a checkmate, a win, it has obviously a very high value. An other example - more complex but helps with the understanding - if you are in a very bad, loosing position and you can force or at least try to reach a stalemate, those moves have a higher value. You're a very good scripter! Keep up with the videos also, they're very interesting and you put a big effort behind them, explaining with simplicity and in an entertaining way a topic like coding!

You actually forgott 2 rules of chess: 1. Long and Short Castling. In which you move the King two spaces to the right or the left if you haven't moved the king before, and then move the Rook from the direction the king moved to on the same line but behind the king. 2. "en passent". If you move a pawn two spaces (first move for that pawn) and there is an enemy pawn that could have defeated that pawn if it only moved one one space instead of two, then the enemy pawn can still actually defeat the pawn by moving one field diagonally, as if the pawn only moved one field.

The A.I.'s understanding of chess is surpassed by first graders. Again, I understand that creating a good A.I. for chess is insanely hard, but Code Bullet failed to even make a functional A.I. His A.I. can't go a full game without making an illegal move.

Even though neutral network takes time to grow, personally I like to watch it grow for hours like a baby maturing.

[@L4Vo5]

So there's something called Leela chess zero, where they tried to replicate the chess AI Google made (AlphaZero, which defeated the top chess engine in a match with 10 wins, something like 60 draws, and 0 losses, after training with itself for 4 hours), but because they didn't have nearly as much processing power as Google they knew they couldn't get it done within a reasonable time, so they decided to make it into a project where anyone can help her train by running a program on their computer. Now, after like 8 months, it also managed to beat the top chess engine! ... In like one game of a 16 games match or something like that. Though, if I'm not mistaken, that level of play means no human can beat it, which is pretty cool. So, it'd seriously take too long for CodeBullet to do it alone, and a simple neural network approach would probably take much longer as well, but if you want you can search online and see all previous versions of Leela, to see it grow from something that plays almost randomly to something that can beat any human.

From what I understand this is actually essentially how deep blue kind of works by trying to get a high value to win. Where now most chess engines are fed data along with brute forcing options and then determines the path that will most likely lead then to a checkmate.

[@dihydrogenmonoxide2878]

I would love to see you improve on this, i for one love to play chess casually, and therefor have never worried about capturing as many pieces as possible, instead it's just about taking the king at all costs. i would love to see you make a smart AI that can actually win a game of chess. part of where i think you went wrong was your objective. in those games we saw of AI vs AI you're AI was excelling at earning points by taking pieces, which is what you told it chess was all about. in reality, a game of chess has 1 main objective, kill the opponents king, a concept that seemed to be foreign to your AI. please do revisit this, and maybe try to make it so the AI is made to win the game, rather then capture pieces. i know this would mean providing the AI with some form of strategy or thinking WAY ahead, but i believe in you and your coding skills. it would also be interesting to see the AI have a resign feature, and when the AI hits a point at which they can no longer win (Assuming the player makes the correct moves) and then, after waiting a certain number of moves, perhaps 3-5, and if this situation doesn't get better, it resigns. resignation is a feature i find is missing from most chess apps, and if the goal is to have the most points, wouldn't resignation be helpful at some point to preserve your own pieces, once you have taken a large number of the opponent's pieces. that's enough of my rambling, love the codes you make, keep up the great content bro.

[@sirrcrowe4081]

Actually, it's to capture the king. To immobilize it. To make sure it has no other moves AND it's in check.

[@dihydrogenmonoxide2878]

Call Me Cro well put, but I find it's easier to teach or explain the rules in that sense, so people understand that although you never actually capture the kind, it has to be set up so if there was 1 more turn, thats what would happen, as someone who has had to teach person after person, I've learned its 10X easier to say "kill the king" and then explain to them that the game is over when checkmate comes up, even though their/my kind is still standing. that being said, you are 100% correct.

Dihydrogen Monoxide If you teach chess that way it’s gonna make it harder for pupils to make the switch And a lot of stratagies are never introduced so Even if it’s easier you will loose more time with capturing pieces

[@nZifnab]

Give the king a point value of 100 or 200 and it should automatically seek to destroy the king when possible. It will assume the opponent will try to protect it's kings at all costs, so it will make moves that bring it into a checkmate automatically because it must trap the king

I'm autistic, so I may not approach things the way most people do. My shrink says I'm "Wired differently." Anyway, when I was 10, I taught myself chess and spent about three days doing lots of games, playing both sides. Then my Dad challenged me to a game. I beat him that first game. Then I beat him the next 4 games. Finally, he asked how many moves ahead I'm thinking. I told him I usually tried to think ten moves ahead. His jaw dropped open. He said most adults can do about three. I'm pretty sure we never played again, but seven years later, we got a TRS-80 computer and eventually coded a chess game in it (Using the built-in BASIC with Z-80 machine code subroutines packed into BASIC strings), which was to me, more fun than actually playing chess. Your project brings back fond memories! P.S. When the IBM PC came out, my gf had one and on her machine (Hey, Carol!) I beat Chessmaster 2000 in 57 moves. That was brutal, but I was so proud I never played it again. I didn't want to spoil my record!

Apart from implementing ALL the rules of the game, you could do some simple work on the evaluation function. Adding up the value of the pieces is one thing. You can then then add increments to each piece for every square it can get to. A knight on the edge and a knight in the middle are not equal in value. A trapped rook is worth less than one on an open file.

I would be interested in seeing if you can take an alpha 0 approach of itterative distillation. That is, taking a neural network, pit it against itself, and generate training data from its own evaluation function, extended from minimax. So, gets maximum reward from ente4ing a state where minimax predicts it has winning moves, minimum reward from entering a state where minimax predicts its opponents have a wining strategy, and it tries to predict what it's own move assessment from minimax would be. The idea is that it would first recognize checkmates and what moves immediately lead to them. Then, it would develop more abstract rules of thumb. Like taking material dosen’t automatically win you the game, but it does tend to give you a statistical edge to getting a checkmate. Then, it would look for other things to achive those ends, like good positioning. The most exciting thing is that there is no real sticking your finger in the wind. You can always just dump more neurons, training time, and deeper search at it, and it would, in theory, develop better and better strategies. When it levels out, increases the search depth, and when that doesn't work, bing bang boom, you've reached about the limit of good play your network can achive.
