Hello,
I am going to make a speech at my club about curiosities of computer chess and about making the people to know the pros and cons of analizing with an engine. I need material for the speech. Would anyone here like to share with me :
- Positions where engine does not evaluate correctly the position
- Fortress
- Sac that are incorrect acording to engine, but could be a very practical choice in OTB human games
- or any position that serves to a teaching porpose for the speech.
Thank you very much in advance.
Fermin

There should be quite some games by Tal as he was known for exactly that style of play.Kempelen wrote:- Sac that are incorrect acording to engine, but could be a very practical choice in OTB human games

Re: Need material for a speech
Probably the most famous game of 2016 was Caruana vs Nakamura, where we see a queen sacrifice that Caruana had prepared and Nakamura had missed in preparation because of incorrect computer analysis: https://www.youtube.com/watch?v=mQ8Qe5O7Qcw
A quote from Caruana:
A quote from Caruana:
https://chess24.com/en/read/news/london ... brilliancyIt is possible to overlook if you’re not going deeply into the position and you’re more or less making the computer’s first line. I think if he played this over the board as White he’d play Nf5 very quickly. I think this is just over-reliance on the computer.

Re: Need material for a speech
I originally posted this position, because I think it is a very good illustration that even top engines are not perfect, and that deep analysis is no substitute for actually playing out the position.hgm wrote:[d]nnnnknnn/pppppppp/8/8/8/8/PPPPPPPP/1Q1QK1Q1 w
Score around +8.5 in a lost position.
It gave rise to discussion that hijacked the thread, however. So I now moved that discussion to a separate thread about Queens vs Knights.
I won't tolerate any further discussion on this position in this thread.
