  • Published on Feb 16, 2019
  • This is a round 63 game between AI Leela Chess Zero v20.2-32930 and Stockfish 190203. It was from the Season 14 Superfinal of the Top Chess Engine Championship 2019. Both Leela Chess Zero and Stockfish earned their way to this final 100 game match. The featured game's key middlegame decision, and its beautiful endgame play make it highly instructional. The opening was a French Defense, MacCutcheon, Janowski variation. The pop quiz in the middlegame position is likely to make even a most experienced player struggle some in determining the optimal path. Instead of counting pawns, let's see which pawns really count!

  • elijah covey
    elijah covey 3 months ago

    Cuz at the end of the game Leela chess sacrificed its Rook on purpose yeah they may resign because they're behind in the game and they're going to lose if they sacrifice of peace at the end it's a blunder then I think it is a learning AI chess engine fascinates me I have intelligent and plays with barely thinking any moves

  • elijah covey
    elijah covey 3 months ago

    There is proof that Leela chess is an AI and anybody can plan on a computer stockfish in Leela chess zero faced against each other Leela chess only two moves second while stockfish thinks 1 million moves a second the one question I have to ask is does it chess engine sacrifice pieces when they're behind in a game or do they fight till the end

  • krishna kishor bhat

    Leela is frugal in promotion of the pawn to a rook, which most likely be taken out in later moves by stockfish.
    Was Leela fishing stockfish with that move? 😁

    You should have mentioned that the outer space pawn (aka fawn pawn) is Leela's most characteristic stylistic feature. She uses it much more often then any other person or engine.

    I really could tell that f7 was a weakness for black in the position. So I said to myself “I guess I would keep the light asqueare Bishop and attack that point”. I am ashamed I wasn’t at the level of that beauty.

    13:57 - I thought Re8 was interesting for Black, but I guess White plays f5? Still seems like a better try than Bxa4 but I must be missing something

  • mtgxerxes
    mtgxerxes 6 months ago

    Can you explain Black's move 7? Blocks in that eventual clown rook? Why would Black choose this over Castling, pushing the pawn, or moving the Clown?
    The pivotal Bishop move to g6 I thought of, but I had no understanding of why it might be a good move and couldn't follow it up, but I at least thought of it!

    11:55 Why does black has to take? Can't the king position be improved instead?

  • Vigil Ante
    Vigil Ante 6 months ago

    The main advantage of a rook underpromotion is there are fewer possible moves for it to calculate per ply--LC0 can go a little deeper for the same amount of time spent thinking. If it sees that a rook is a win, there's no need to spend any additional time checking that a queen is also a win (could be a stalemate lurking somewhere.)

  • Steven Wolfe
    Steven Wolfe 6 months ago

    While I do like the idea of the rook under promotion acting as a taunt, or being an optimization for computational power, or a simple roll of the dice, I think it had a purpose. If the game had continued, the piece would have guaranteed been traded. Leela chose to promote to rook since it put the same pressure on the board as a queen (particularly on both the rooks in the 8 row) and since it was worth less points. By accepting the trade (with little other choice), Stockfish would gain less points than if Leela had promoted to a Queen. The optimization wasn't in computation power (less decisions to make for a rook), but rather of the number of points Stockfish gains.
    However, the sentient move to me was Stockfish's final move before surrendering (Kc6). To me, this move is a pseudo "tipping of the King" programmers probably added in for Stockfish. Poor Stockfish. ;')

    To be perfectly HONEST with you Jerry, I found bishop g6 straightaway but my idea was pretty much that was it. Take my bishop by messing up your pawn structure.

  • EdLena
    EdLena 6 months ago +2

    I accidentally left stockfish analyzing move 20 for white over night. It worked it's way through 53 ply! The result being 20. Bg6 += (0.75) to 20. Bxc4 += (0.47). I don't know what computer was used during the match but it would have been greatly superior to my old dual processor and may have reached the same conclusion that Leela did.

    What if 14...Nxd4 immediately? The f pawn would still be on f2 instead of f4, preventing a bishop retreat to f2, and the kingside pawns would be a turn slower.

    Stockfish 10, 20181206:
    Hash = 16 GB, Overhead = 30, PV = 3, even number of plies > 26:
    {[28] 7.55:} 41. f8=R Rdxf8 42. Rxf8 Rxf8 43. Bxf8 {etc.}
    {[28] 7.37:} 41. f8=Q Rdxf8 42. Rxf8 Rxf8 43. Bxf8 {etc.}
    {[28] 4.87:} 41. Rf4 Bd5 42. f8=Q Re8+ 43. Kd2 c3+ 44. Kxc3 Re3+
    45. Kd2 Rxf8 46. Rxf8 Rb3 47. Rf7+ Kc6 48. Rc1+ Bc4 49. Bc5 Kd5
    50. Re1 b4 51. Rd7+ Kc6 52. Ree7 Rd3+ 53. Ke1 Bb3 54. Kf2 Kb5
    55. Rb7+ Kc4 56. Rxb4+ Kc3
    Thus Stockfish would be joking, too!

    At 6:09 I really wanted to play c3 and retake on d4, put the king on e3,a rook on b1 ressembling a game from the 10 original AlphaZero Stockfish match and eventually break on f5, when I saw the pawn on g6 I completely realized why I was wrong.

  • Jiro Conwi
    Jiro Conwi 6 months ago

    In game theory, when you expect the opponent to play in the most optimal way and you only base winning via probability, there are cases when having the 'weaker' choice becomes a better option to make the opponent move in the optimal-predictable way. Therefore AI does underpromotion.

    Man I'm learning to be aggressive with all these Leela videos, I actually saw the Bg6 move. Although I had the direction of the black squared bishop wrong, I thought about going Bb2 to have the a3-f8 diagonal

  • Theo Birkholz
    Theo Birkholz 6 months ago

    I have a question about black's 7th move, 7. ... Kf8. wouldn't Nxc3 be much better here? you pick up the knight and you have a discovered check right around the corner. Also if white recaptures with 8. bxc3 black can play Bxc3 and fork the king and the rook.

    Also, why kf8 and not O-O, or Rg8?

      tun nay 6 months ago

      Most SF win (won by AB engines) are due to deep tactical lines where the positions are too complicated to be visually access by human calculation ability or practically impossible for human to calculate and follow.. For comparison, Leela calculate x1000 times faster than human, Stockfish calucate X 1,000,000 times faster than human

  • EdLena
    EdLena 6 months ago +1

    Actually according to my Stockfish version it was split on it's choice for white's move 20. It had Bxc4 += (0.39) or Bg6 += (0.37). I find there's a general bias toward AI chess software because it's more 'human like' than the purely machine calculators. That's why we always see AI wins and rarely an AI loss.

    It took a few moments but I also thought Bg6 would be good... if you gotta give up a piece may as well break down the opponents pawn defense and get a pawn of your own one step closer to his king while you're at it.
