I think that op should understand that their is different between normal reasoning and skill as per say, what I want you to understand from my own understanding concerning chess game is that it's a game that deals with reasoning while trading is a skill you acquired from someone else.
I do agree with that, but I'm sure OP's writing is from another perspective where he might be trying to indicate that when a healthy mind practices the panic moves, recurrent decisions in a game this exercise really assist in the efficiency of the decision-making kind of similar scenarios in the trading as well. I've said what I think in my first impression of Chess vs trading.
So saying that chess game will enhance someone who is a trader to do well in trading I think is not a cogent reason, in every section they have their own strategy and if their strategies is a welcomed development we can dance to the tone as much as we can, but primarily a chess game don't have anything to do with trading skill as you point out.
Chess and trading may seem unrelated, but they share a common thread in mindset, adaptability, and strategy adoption. While the specific moves and fields differ, the pressure of emotions remains similar.
