> If you aced question 4, and most of the rest of the test also, yes, it would be easy to explain. Especially right after it happened, even if you're tired. If an answer is obviously correct to you, you should be able to explain how.
You clearly have never been through a four hours math exam with open questions.
There is no obviously correct answer. There is the way you tackled the problem and the myriad of other ways you could have done which might be more or less obvious, easy or correct.
It’s the same with chess. There is the line you played, the line your opponent played, the other lines you could have played which you did or didn’t consider, same with your opponent. Some of them you considered seriously, other you didn’t. Plus all the things you missed but didn’t matter because your opponent didn’t go there.
Also, you seem to believe chess players are doing post-game interviews because they want to. It’s not the case. It’s a mandatory part of participating in the tournament. Most of them would decline them if they could.
And yes Niemann is infamous for hating post-game interviews and always giving poor answers which is why I’m surprised people actually base their argument on this.
