I think 16-personality Types can be used to define a chess player's style

If you see characteristics of a person with a certain personality Personality Type, then chess players should have a playing style based on 16-personality test too. This is how:
E and I.
Extroverted people are often social and often like to talk to other people. In chess style traits, they are risk-takers. Extroverted people are risk-takers.
Introverted ones display quiet energy. They don't want to socialize that much and they focus their attention to themselves. In chess styles, they prefer calmer approach than risky approach.

N and S
iNtuitive chess players have good imagination and prefer to look at the big picture rather than calculate and sense. They infer more than they observe.
Sensing cps are calculators. Sensors observe more than they infer.
Many iNtuitive chess players are good at calculation.
Many Sensing chess players are good at intuiting.

T and F
Thinkers do what they think is correct. Feelers do what they feel is correct.
Thinkers assess positions differently than feelers. Thinkers use either their sense/intuition to assess positions. Feelers assess by looking if the position is inside or outside their comfort zone.

J and P
Judgers are planners. They go with the plan instead of going with the flow.
Perceivers are open to ideas. They go with the flow instead of going with the plan.

(Turbulent types are more likely to be self-conscious perfectionists, concerned about their abilities or about how others perceive them.)-https://www.16personalities.com/articles/the-turbulent-personality-dont-worry-be-happy

 
Assertive ones tend to be calm, relaxed, and free from worry according to https://www.16personalities.com/articles/the-turbulent-personality-dont-worry-be-happy


Now, we may group these personalities into four, but this must be very hard. What two traits determine general styles?

I think it must be related to the first two traits, EI and NS.

• ES are sensing attackers
• EN are Intuitive attackers
• IS are positional sensors
• IN are positional intuitors.
  
  Or first-third traits?
  
  ExTx
  ExFx
  IxTx
  IxFx
  
  I feel IxFx's are the calmest players.
  
  What do you think so? Am I right?

It feels a bit wrong to say "you play like X" because "you are P or J" I found my self going full berserk mode in some positions and very very slowly positional on others does this make me a "universal player"? probably not. Most likely the chess personalities test is just not good enough, or just using common sense and not real "facts"

Even if the Myers-Briggs personality types were real (a pretty dubious proposition) correlating these with chess play--at least good chess play--probably doesn't work so well. Although it is true that some famous players have been identified as "aggressive", "tactical", "positional", and so on, most have not. And at any rate, this is far too simplistic. To be good, and certainly to be great, you need to play well in all contexts. Petrosian, for example is commonly known--and rightly so--as cautious and defensive. But he could still launch some brilliantly tactical attacks.

Too, good play involves planning and intuition, understanding the entire board and calculating specific lines.
