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.

    Well, I took the time to download the latest version of Stockfish and let it run through these positions and, as surprising as it is, it did come up with the right ideas in every puzzle except for the first one (I was too lazy to wait for it). In some puzzles it is true that it evaluated the position as losing, or with an advantage for black, when it was a draw, but even in those cases its best move was the one showed in the video

    After b4 and either axb3/cxb3 is done (doesn't matter which) you get Rxa2, bxa3, Kb2 will stop the promotion of the queen, and white can now advance to either a4/c4 depending on which pawn captured enpassent, allowing them to move their knight to either a3 or c3 and allowing the rook to escape via the b file

    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.

    in the first position, why couldn't the black A or C pawns just en pessant the B pawn and be protecting the A2 pawn while attacking the rook? 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.
