Are there any moves from real, preferably reasonably well known games which humans agree are great moves, but which engines cannot see, or, at least, think are weak/average?

Here is an example that I know of (although probably not a great example) from a Kasparov-Topalov game called "Kasparov's Immortal" on chessgames.com. After Topalov played Qd6, Kasparov sacrificed the rook on d4, which Stockfish depth 71, as said in a video by the Chess Club and Scholastic Center of Atlanta, still thinks to be just an acceptable move. But it is a move which human players may consider to be extremely creative and very strong.

Are there any moves in well known games which engines don't recommend, but which the best human players would prefer?

    Actually for that specific position, SF 13 figures out that 24.Rxd4 is the best move at roughly depth 28-29. SF just doesn't say Rxd4 is winning, as 24...cxd4 allows Black to draw with perfect play, while 24...Kb6 even gives him a slight advantage. But SF still gives 24.Rxd4 as the best move since everything else is bad for White. Commented Jun 19, 2021 at 16:30
  • @InertialIgnorance interesting. In the video it says the engine (SF13) says Rxd4 is not the best move at depth 71. Are you able to test at greater depth (perhaps SF finds a better move between depth 29 and 71?)

    @stevec On chessbase's cloud evaluations, I can see someone let their SF 13 think to depth 53 on this position today (likely because of your question). Not sure if that was actually me unless I left my engine running for a while, but it looks like 1.Rxd4 is given as the top move (with a -0.13 evaluation). Earlier today I saw 1.Rxd4 given with a 0.00 evaluation at depth 71 on the cloud (someone generated it in april), but I no longer see it listed at the moment since chessbase only shows three evals.

    @stevec I'm guessing Finegold saw this same depth 71 evaluation that said 1.Rxd4 was "only" equal, and that's why he made the comments he did. But he's likely inaccurate in saying that the engine saw a better move. Commented Jun 19, 2021 at 23:06

You may be interested in the chess.com article 10 Positions Chess Engines Just Don't Understand, by NM Sam Copeland. If you don't like reading, there's a video by the author and another video of Hikaru reading through and giving his thoughts.

A frequent theme in these positions are setups with long-term factors that engines are not aware of, in particular closed positions where a human can see it is impossible to make progress, and lengthy maneuvering plans.

  • or it can be the opposite, not seeing the draw for spatial restriction unstable "equilibrium" combination of piece placement, that a human would know not to explore candidate moves in vain, and that the exhaustive search engine would keep wandering into, when lost of space, so not closed, but probably still confined region where such placement configurations can allow a fortress from the piece type mobility geometry or figure restriction union. Thinking corner, knight bishop mutual protection king sufficiently mobile in corner. opponent king and queen both unable to combine restriction.

I recall an amazing move made by Peter Leko against Vladimir Kramnik, as told by the YouTuber agadmator in a video, published on June 10th 2018, entitled "Invisible to Engines | One Of The Greatest Moves Ever Played". The game can be relayed chessgames.com with notes provided by Raymond Keene.

[Title "Vladimir Kramnik-Peter Leko, Classical World Championship Match, Brissago Switzerland, 10/7/2004"]
[FEN ""]
[startply "49"]

1. e4 e5 2. Nf3 Nc6 3. Bb5 a6 4. Ba4 Nf6 5. O-O Be7 6. Re1 b5 7. Bb3 O-O 8. c3 d5 9. exd5 Nxd5 10. Nxe5 Nxe5 11. Rxe5 c6 12. d4 Bd6 13. Re1 Qh4 14. g3 Qh3 15. Re4 g5 16. Qf1 Qh5 17. Nd2 Bf5 18. f3 Nf6 19. Re1 Rae8 20. Rxe8 Rxe8 21. a4 Qg6 22. axb5 Bd3 23. Qf2 Re2 24. Qxe2 Bxe2 25. bxa6 Qd3! 26.Kf2 Bxf3 27. Nxf3 Ne4+ 28. Ke1 Nxc3 29. bxc3 Qxc3+ 30. Kf2 Qxa1 31. a7 h6 32. h4 g4

The move in question is Leko's 25... Qd3! Keene's notes summarize it neatly: "The key move which Kramnik and his team had underestimated before the game."

I believe that agadmator's narration, starting at 7:13 on Kramnik's move 24th move, gives enough context for an answer. I have written a transcript.

"Kramnic immediately played queen captures on e2 and it seems like a winning move and in fact Kramnic had this position on the board before the game. He and his team decided that this was of course winning for White. It's okay, bishop captures on e2 and now b captures on a6. It seems that for the queen the only compensation Kramnic has is this rook, a rook and a nice passed pawn that is ready to go to a7 and a8. So you kind of don't want to allow pawn to a7 and a8 and this is the position I've been talking about. So here bishop captures on a6 is the idea and every engine I've tried give bishop captures on a6. But this is why this game is so famous and this is why this move by Peter Leko is so famous. It's one of the legendary moves played in chess history and I really do want you to pause the video here and try to find this move. Give it a minute or two and if you can afford more give it more. But even if you don't find it or don't really know what to find it then I also invite you to try out your engines. Maybe your engine can help you here because I haven't actually found an engine that can solve this position."

    To be fair, Stockfish 13 does see the move in a couple of seconds, although engines at the time did not. Commented Jun 19, 2021 at 5:23

    Another position Agadmator covered which engines (still?) cannot see: youtube.com/watch?v=8wCJalNkTEI. It's a puzzle rather than a real game though
