To start off - due to my anxiety, I do not play any form of chess against other people (except some friends of mine, but that obviously doesn't matter for the context of this post).
I recently got really interested in how cheating in chess operates and how it's detected. Specifically, this post gave me a lot of ideas how cheating is detected in general.
However, I have been wondering about the following scenario: let's imagine somebody is playing online chess, and they can see the evaluation bar in real time, with no additional information. For example, after blundering a piece, the player would immediately see that his opponent is better off. The same would be true the other way around - the player could see that his opponent made a mistake immediately, but without knowing what mistake that was exactly, without seeing any engine moves or possible threats.
So now my questions are:
- How would something like this even be detected? Especially at lower rating, since the player would probably not be able to interpret the results correctly (most of the time anyway).
- How much of an advantage would this really give? I assume for lower-rated players this would barely do anything, but for more skilled players, would this really be a lot?
- How much would the time control affect the impact of this? Would fast chess benefit less than classical?
Do you know / have you heard about this method being used by players? Any insights are welcome, as this is a question asked out of pure curiousity.
