Chess Engines Are Wrong About These Positions

Join NM Sam Copeland ( @The Best Of Chess Channel ) as he breaks down 5 chess positions that chess engines don't understand. Despite the clear superiority of engines, there ARE positions which chess engines don't (and possibly can't) understand that are quite comprehensible for human players. Typically these positions showcase the human ability to think creatively and formulate plans and understand long-term factors in the position.

    @Utsav Joshi I have checked this myself also. The Giri game was the only one SF did not find the "right move" since it went for a more complicated longer approach. But the rest it found all the right moves, but *crucially* the eval was wrong for 2 of the puzzles... (meaning it wouldn't have gone for the drawn positions in a real game)

    stockfish held as white in the last position until 50 move rule although it thought the position was +4 for most of the game. Then it pushed the pawn and the eval was 0. Stockfish was able to solve every single puzzle.

    That first one was just asking too much. Stockfish normaly checks 18 moves into the future. You need to tell it to keep going and it should find it. Chess AIs aren't wrong about positions that require 20+ moves, they just arent allowed to look far enough ahead.

It'd be a much cleaner move for black to play, stop the past pawn and force black to move it's rook to the b file or surrender it, making black's victory nearly inevitable, no?

    Sam, you've taught me you don't know how to understand the output from a chess engine. Here's what I recommend to you. First, understand that stockfish doesn't display 0.0 for every drawn position. This should be easy, you have examples in this video. Second, learn how stockfish communicates that it sees a blockade. This should be easy, look at what stockfish displays for the first position in this video; a complete inability to make progress by moving. Third, teach people something useful for a change.

    After that en passant capture, white can free his position up because his own a-pawn isn't blocked anymore. For example, after axb3 en passant, white could play Rxa2. Then after ...bxa2 Kb2, no matter what black does next, white will eventually be able either push a4 and get his N out via a3, or get his remaining R out via the now open b-file, after which winning is trivial.

    Stockfish 13 understands position #1. Rooks on E1 and C2, King on C1, plays Qa2, which is captured, then b4. Depth 39, in 1 second: 1.Kd1 Kc6 2.Rg2 Kd5 3.Re2 Ke6 4.Rg1 Kf7 5.Ke1 Ke7 6.Kf2 Kf7 7.Re1 Ke6 8.Rg2 Kf6 9.Rc1 Ke7 10.Ke1 Kf7 11.Re2 Ke7 12.Kd1 Ke6 13.Re1 Kf6 14.Rc2 Ke7 15.Kc1 Kf6 16.Qa2 bxa2 17.b4 ... Afterwards, Black sacs the Queen for the Rook, to capture the passed pawn. White announces Mate in 23 (which will likely improved if I let it continue to think over a few minutes).

    I have never understood the overrated enthusiasm for chess engines, because people fail to see how limited they actually are, including Alpha Zero. The total number of possible chess games is an estimated 10^140 (the so called Shannon number). When you compare this to the estimated number of atoms in the universe, which is 10^80, you might realize that chess engines will never be able to process a game in full depth. They are actually just scratching the surface, just like we are, only a little deeper.

    They think because they are computers and the far exceed the skills of many of our capabilities as humans, that makes it seem like the computers are playing optimally. But as you said, that is not the case. The current engines we have are indeed powerful, but by no means optimal. We could see, in the near(?) future, even more powerful computers that can crush AlphaZero like AlphaZero crushes us.

    The only position I couldn't see a plan. Although I've analysed a couple of these positions before. I found the plan in the first one, since it's basically the only plan and it just involves understanding that Qa2 is the only way to break the position, and conceptualising how to defend. Once you understand that black cannot take a rook, the rest is easy.

    But in that case you play d2-d3 instead of d2-d4 to make sure the position opens up ...

    8:15 promoting the a-pawn to queen or rook leads to stalemate as the black bishop is pinned and the black king has nowhere to go... i would rather underpromote to a bishop instead and force the black rook to defend the back-rank... but in this position, moves like b4 or Ra6 makes more sense than underpromoting the a-pawn to bishop or knight.

    After b4 or Ra6, there's Rc8 and Ra8.

    Engines are not designed to cope with these specific positions, especially the blocked ones, but to deal with positions in general. Reprogramming an engine to deal just with these would actually make the engine weaker overall. It's not worth it.

    It does not necessarily make the engine weaker. With Stockfish 13 NNUE, they have figured out a way to solve these closed positions while making the engine stronger on my PC, Stockfish 13 NNUE on arena GUI was able to solve all of these positions.

    Nah, they pretend not to understand so that we don’t feel inferior
