I was reading this article https://en.chessbase.com/post/why-chess-players-blunder and curiously I set up the position they were talking about - Carlsen-Aronian, 6th Norway Blitz, 2018 (8)
[d]8/6p1/8/7p/3kP1p1/5P1P/2K2P2/8 w - - 0 1 and all the engines I have pick 52.hxg4?? which is the move Carlsen used and it's completely losing as you can't stop the passer. WHY are the chess engines doing this?
Why do the engines pick this losing move?

Re: Why do the engines pick this losing move?
If you take an engine rated close to Carlsen and Aronian it will NOT pick the Wrong move. Here is Dumb 2.1 rated around 2850 like Carlsen.reflectionofpower wrote: ↑Tue Apr 16, 2024 3:31 pm I was reading this article https://en.chessbase.com/post/why-chess-players-blunder and curiously I set up the position they were talking about - Carlsen-Aronian, 6th Norway Blitz, 2018 (8)

NOTE: In my Opinion this Dumb engine can easy beat Carlsen

Re: Why do the engines pick this losing move?
Dumb 2.1 is still Dumb and so are the Smart engines. 52...hg4?? is losing instantly as it allows the passer as it allows the winning move h4. All my engines pick h4 after the howler 52...hg4??

Re: Why do the engines pick this losing move?
... means black move and after the correct 52.fxg4 that engines suggest the move 52...hxg4 that is not losing.reflectionofpower wrote: ↑Tue Apr 16, 2024 3:51 pm Dumb 2.1 is still Dumb and so are the Smart engines. 52...hg4?? is losing instantly as it allows the passer as it allows the winning move h4.

Engines do not play the losing move 52.hxg4 that allow for black 52...h4

Re: Why do the engines pick this losing move?
I think it's the Lonnie Brain engine v.1.0 because I just woke up and thought I found a sleeper. My mistake and apologies.

Hello:
52.- hxg4?? is a disgrace, being gentle. Huntsman sees a checkmate in 15 moves after 52.- hxg4??, h4:
