This expert bot just made Martin look like a Chess grandmaster 6/9/24: After playing Martin in his Gen Martin version, this comment aged like a fine wine.
Missing mate in 4 must have something to do with the evaluation function. Some chess programmers purposely change the evaluation function for various chess bot "elos". For example, Martin. The programmers intentionally tweaked the piece square tables, material, and other evaluation factors such as pawn structure and mobility. In this case, it could be a lack of search depth, or errors in alpha-beta pruning, or a defective evaluation function. 🤓 (P.S: Yes I made a chess bot and did all the research)
@@scorpiece1765 1:30 1. Ka1 Nc2+ 2. Kb1 Na3+ 3. Ka1 Qb1+ 4. Rxb1 Nc3# 1. Knight checks, no piece can take the knight | 2. White's king is forced to move to b1. The knight checks again, with a discovered check coming from the queen. | 3. White can't stop two attackers at the same time, so it must move. c1 would result in Qc2#, the queen is defended by the knight. King moves to a1 instead. The queen checks, moving in front of the King. King can't take the queen because she's defended by the knight on a3 | 4. White is forced to take the queen with the rook. Knight moves to c2 and it's checkmate. A knight checkmate with the king trapped is called "Smoothered Mate" And sorry if I told you anything you already knew, I just wanted to write this in a way everyone can understand.
@@officialcappoI can correct it Bot: Lets play book moves! (Makes a blunder) (starts playing like a maxed elo bot) (Realizes the bot was playing good) Bot: Lets do a queen trade) This isnt 100% accurate but i got most of it
Weaker bots are normally just stronger bots programmed to make worse moves and occasionally blunder on purpose, so it giving up the queen was just it deciding to blunder (or a bug)
for the record, if white would've taken the queen with a rook it would've been a smothered mate, they just simply overlooked the fact that the king could capture it as well. I could kinda see a human make a blunder like that.
Simple and correct answer, bots and AI are nowadays mainly when it comes to games being trained by others of themselves, that is, they are trained against bots which makes them extremely technical.
maybe that chess bot is made to be a rollwr coaster instead of trying its best ,it beats you up then freaks up or sometimes make it almost like a mistake to contrast how close you were to losing,like it wanted to do smothered bu in the wrong order
while I was watching this I was like "Take the queen with the pawn" to realize the pawn is defended by the bishop... this is why I always blunder my queen
Bots that, in any game, are able to completely dominate players but have to choose to make bad decisions are always gonna be unfun to play against, especially when its just random.
Yes, these bots can be quite predictable. I found moves that very often leads to winning position on hardest difficulty, because for some reason bot do not always play optimal moves. Playing as black, if you manage to do 1. e4 e5 2. Nf3 Nf6 3. d4 (hardest part because of low chanches of bot playing that), you can get a better position with 99% chance after: 3. Nxe4 4. dxe5 c5 5. Qe2? Bxf2+ 6. Kd1 d5 7. exd6 Qxd6 8. Nbd2? f5 9. Ng5? O-O 10. Qc4+ Kh8 11. Nf7+ Rxf7 12. Qxf7 Bd7 13. Bd3 Nc6. Here you already have big advantage, but position is hard, and bot have various move to play next: 14. Nxe4 (most common move) 14. Nc4 , 14. Rf1 or even 14. Qb3. If knight takes e4: 14. fxe4 15. Qxf2 Bg4+ 16. Kd2?? (Ke1 is best, but played not often) exd3 17. Qg3?! Ne5 18. cxd3 Rd8 19. Re1 Nf3!! 20. Ke2 Qxd3+ 21. Kf2 Nxe1 22. Qxd3 Nxd3+ 23. Kg3. Here you can play Nxc1 or move bishop, but you still entering endgame with extra piece, so its easy win. Engine says theres mate in 20+ on 18 move, after cxd3, but continuation is hard to remember, so I prefer to exange some pieces.
I believe theres similar tactics for every difficulty, which most likely forces win, but I haven't found it, bot playing randomly. But theres few things, which can help. For 1-level bot difficulty (the easiest one) scholars mate works fine. For 2, 3 levels Danish Gambit works fine, because after 1. e4 e5 2. d5 exd4 3. c3 Bc4 4. cxb2 Bxb2 5. d5 Bxd5 6. Bxf7+ Kxf7 7. Qxd8 Bb4+ 8. Qd2 bot will not always recapture queen, since its first move out of theory and bot have to play bad, so you have huge advantage. Of course, on these levels you can play whatever you want, computer makes a lot of stupid mistakes, and you can easily win even if you bad at chess. For levels 4,5 I recommend play Alekhine Defence (you play as white, bot move knight on first move). I analysed a lot of theory and turns out, alekhine defence have hightest advantage for white (+0.7). Pretty solid opening for white, also, if you playing second main line: 1. e4 Nf6 2. d4 d6 3. Nf3 Bg4 4. Be2 e6. 5. h3, theres a high chance of bot playing 5. Bxf3 6. Bxf3 and after that very often bot hanging both rook and pawn by moving knight on d5, or you can use your c2 pawn to help with that, leads you to easy game. But if not, it still very easy to win, because at this level computer blundering pieces a lot. For levels 6,7 you struggle with first problems, because beating bot is not that easy now. Usually I play variation of Rubenstein Counter Gambit as it called: 1. e4 e5 2. Nf3 Nc6 3. Nc3 Nf6 4. Bb5 Nd4 5. Nxe5 Qe7 6. Nf3 Nxb5 7. Nxb5 Qxe4 8. Qe2 Qxe2 9. Ke2 (and yes, this is all theory) Nd5 10. Re1 a6 or Be7 (other moves are very annoying, especially f6, which leads to slightly advantage for black) 11. Kf1 Be7 or a6 12. Nc3 Nb4 (computer playing Nb4 more often that Nxc3, so thats okay) 13. d3 Nc2?! (looks like a fork, but actually innacuracy) 14. Bg5 f6 15. Nd5 Nxe1 16. Rxe1 and here you have your full army ready to attack your kings, so small step in the wrong way leads to disaster for bot, and since its middle level, bot will do terrible mistakes. You can win a rook, two rooks or even a king. The knights is very strong since they can do different forks or help with invasion of your rook to 7 rank. So, what about 8 and 9 level bots. I have no idea. I did a lot of tries, but I think the 9 level bot is true the hightest difficulty, not 10. 10 level bot play usually play same moves over and over, so you can easy predict and make a strategy. But 9 level bot combines best moves from 10 level bot and little part of random, which destroys everything. I think to beat him, you really have to be good at chess, unlike me. Speaking of 8 level, only good tactic i found is trying to trade every piece on board and play safe, draw openings. 8 levels is a little worse than 9, so it have a chance to make mistake, and this chance increases with every move, so in endgame bot can make one wrong move, which leads you to win, and since you both have not to much pieces, theres no too much things to mess up.
Fue un sacrificio tonto e inteligente. Tonto porque comiendo con el rey no pasa nada; pero en cambio si capturabas con la torre el te daba un mate con el caballo. Realmente es increible como piensan los modulos
I remember my brother told me to play the hard bot in this same chess android app and won against him. He was impressed but I told him that he is just stupid. Idk man maybe this app plays random moves on every difficulty idk
