Objective self-criticism is the foundation of chess improvement.
Emotional detachment & chess improvement.
Just a random thought to put out there.
People who fight in MMA says the same thing.
A thought that already came to fruition: Computer chess.
A computer is a marvel of un-emotional.
I see people with dogs. Dogs have all of our emotions, none of our intellect.
The computer has all of our intellect, none of our emotions.
I don't know which way to go. People have thought about it forever.
Computers can be frustrating, they play super well positonally, which stresses you out, but then they make some tactical blunder like hanging a piece or not pushing their advantage.
F that hideous advice.
I learn from chess, in life (and sports), what matter is who is ahead on the scores, it doesn't matter how.
True story.
I know a lady who is on disability (compensation). She has 3 dogs. She is really on disability. She's not faking it. She cannot deal with the cold hard world of work.
Like her dogs, she is emotional and domesticated.
It's a hard cold world out there, just like playing chess with a computer.
I'm VERY logical, so much that I just don't get 98% filtering EVERY single thought through an emotional lens any more than others get my indifferent lack of emotion constantly, but it does NOTHING to help me understand positional concepts at all. FOUR different books were unable to teach me a simple pawn ending, and it's OTHERS that refuse to accept my abstraction allergy. If I can't VISUALIZE a problem like I can tactics and targets, I can't solve it.
When I've faced a dozen lower rated players I can't beat... oh, I emote. LOL.
It's always been the same
It's Just a complicated game
I definitely play better when I'm a bit cold and detached. More objective, more flexible when it comes to changing plans and ideas.
Being too emotional, on the other hand, is a sure path to tilting. Being too emotional can also lead to playing in a stubborn way, determined to make something work at all costs.
Still, you ideally want to have some emotional investment. Otherwise ... what's the point?
I am by no means a psychology expert, but for me, it helps when I am emotionally neutral during a game. That's when good critical thinking skills are at their best, it seems for me. Just a random thought to put out there.
