what ways can you win a chess game with psychology?

No way(s) to win  ...  with psychology.      Just move pawns and pieces.

Yes, there is psychology involved  ...  and hundreds of books are written on this subject.

When you are serious, please make your question more clear, give examples.

Obvious example would be high rated vs low rated player.

High rated player makes an harmless  move with the queen, but the lower rated imidiately receives that as act of war and he is thinking already in wrong way. Or for example OTB after he lands the pieces he moves it left-right like he cementing that piece on that square.

Simple, rough your opponent up and threaten to break their legs if they you don't win.

There is no way to win with mental tricks. The only way to win is with good moves. I didnt think my own people could be so dumb and ignorant when it came to chess. Havent you red Fischer's quote regarding your question? Look up for it, and vote for me.

Winning a chess game doesn't just hinge on your prowess with the pieces; it also deeply involves the psychological battleground. Employing psychology in chess can take various forms:

The Art of Deception: Your moves can craft a narrative or set a trap where your true intentions are masked. This strategy can unnerve your opponent, leading them to second-guess their strategy. Deception might involve making a seemingly weak move that conceals a potent threat, nudging your adversary into a false sense of security.
Time Pressure: Utilizing your time efficiently while putting your opponent under time pressure can cause them to make hasty and less optimal decisions. This doesn't mean playing rapidly without thought but maintaining a steady pace and making strong, confident moves that force your opponent to use more of their clock.
Maintaining Composure: Keeping a calm and composed demeanor regardless of the situation can be disconcerting for your opponent. Avoid showing any signs of frustration or satisfaction with the game's progress. An unwavering facade can make it harder for your opponent to read your state of mind and strategy.
Adapting Your Style: If you know your opponent well, adapting your play style to one that they find uncomfortable or difficult to deal with can give you a psychological edge. For instance, if they prefer slow, strategic games, increasing the pace and creating a complex, dynamic position could throw them off balance.
Psychological Endurance: Chess matches, especially in tournaments, can be lengthy and mentally draining. Preparing yourself to maintain high levels of concentration and stamina more effectively than your opponent can lead to them making errors as the game progresses.
Body Language and Gestures: Subtle cues through body language can sometimes lead your opponent to doubt their analysis or feel uncertain. However, this must be done subtly and should not cross into unsportsmanlike behavior.
Confidence and Attitude: Entering the game with confidence can psych out your opponent before the pieces even move. If you carry yourself as if you have a winning strategy, your opponent may become more cautious or second-guess their moves.

Psychology cannot directly affect the result of the game. Experienced opponents do not succumb to these psychology tricks.

Are you replying to the OP from 2016, or to the ChatGPT user guy?

"I don't believe in psychology. I believe in good moves." - Bobby Fischer

This depends on how good are you as a psycho student! If you are only an amateur the subject can go out of control or he can think the winning move and you will lose. If you are a psycho GM he never has a chance when you will use your tricks of eating a lemon during game play or using a very strong yellow color shirt etc...

You can slowly squeeze him - Karpov style, and there's the Kasparov rule:

I guess the squeeze works good on tactical players (no space --> no good position --> no good tactics), and the 10-threats in a row rule works good against positional players. But how to actually get to a situation of having 10 threats in a row is beyond me.

==&&==

I don't calculate better than my opponent, I understand the psychology of the average opponent, and what I normally do is provoking him to push his kingside pawns (who guard his king) forward, sac a piece (minor or rook) on the h and g pawns - who are already advanced and got far from the king. And then he technically doesn't have a defense, so when my pieces come (a queen, and a piece to support her majesty), it's all over.

The psychology here is, when you put a piece close to his pawn guardians, he HAS to move them - that's a psychological rule.

This post is older than 5 years why is it resurfacing now?Also is psychology really a factor in playing chess?

...You can even break the London System:

An example of the use of psychology that I once saw.

A local player was very good at five minute chess. Whenever, he played in tournaments, he was always in time trouble. Instead of taking their time and complicating the game, his opponents started playing fast, which was what he anticipated they would do. In essence, they put themselves in time trouble. Their reasoning, "I didn't want him thinking on my time." He won most of those games.

In my early chess learning, I used to play Black the following way:

Inviting them to play gambits, and knowing the refutation to those gambits, thus getting a better position.

But there are so many of them... I can't handle them all.

Nowadays I like Scandinavian Qa5, the fact my queen is free while their queen is not, drives them Mad.

One aspect of psychology is knowing your opponent's personality traits. I once played casual games against a club member who would only play the weaker members, and he would verbally humiliate them when they made a mistake. In our last game, I was behind and "hung" a piece. He grabbed it with delight and started his diatribe as I proceeded to draw the game by repetition.* To say that he was enraged is putting it mildly.

*Which his grabbing the "hung" piece allowed me to do.

If you have a queen and let's say your opponent has a rook. Then you can start a non-repetitive checking and moving cycle that will psychologically disintegrate your opponent. An example can be seen in this game from moves 28 to 166 :
