Is it psychology?

Most of the chess players choose whites. Why? Is it psychological or something else?

It's the allure of the first move. White can have an eentsy teentsy advantage, if he plays his game aggressively. It won't necessarily win, but he gets to determine a lot of the tone of the game.

Racists imo

Also, since a lot of computer programs use white as the default color, probably there are a lot more people (especially in the lower ranks) who are more comfortable with white.

Yes, it is psychology.

Take this as another example: most men are like servants mentally. Hence in tennis if they win the toss, they like to serve.

I believe it is based upon how strong players dictate the moves of those having to keep up with their forceful attacks. The idea behind the black pieces in such an event, is to counterattack, thus making the white attack become more reflective. From there, it appears to be mathematical calculation, though mathematical calculation may be of the most subtle variety. Extreme concentration, and familiarity of position(intuition), under the pressure of time constraints, may be decisive in drawing an error large enough to influence the course of the game.

It is because white pieces are lighter and therefore less taxing on our energy to move.

 Yes, I think this is the real reason. I take back my tennis example and agreeing to psychology.

But as an after thought, on a PC players have to only move and click the mouse - using same energy for black and white. So then, why the difference? Perhaps my agreeing to psychology was correct and the tennis example should hold.

The same psychology that makes people buy overpriced shiny white Macs makes people choose white. People like white.

I always used to prefer Black.  Still do, slightly.  I like feeling like the other person is more aggressive.  It makes the game more balanced for me.  I feel more comfortable with a Dutch than a Bird, in most instances.  

That doesn't make sense.  You serve because you get first hit.  Would choosing White make you a servant too?  

 It's a complex and difficult concept to undertand, BirdBrain.

I understand the concept, but I also understand the concept of power and control.  I can see one person interpreting it as a servant, but I see one person interpreting it as power and control.  Accepting to serve in tennis means you get to dictate initial power.  Just like White in chess, or choosing to receive the football if you win the coin toss.  But that being said - beauty is in the eye of the beholder :-)

I really don't care which I play. I will play not to lose. Of course I'd rather win.

I have a friend of a relative that shows up at family functions. He likes to play chess but he must have BLACK all the time. He feels he never loses a game that way.

At a birthday party before Thanksgiving he asked me to play a game. We went into the kids bedroom and set up the chess board. Of course he took black, he insisted. As we played and it was a see saw game. Almost at the end game he made a move with a piece and left his queen to be taken. As I reached to take it with a smile on my face.

He said, "Oh no, that is not what I meant to do." and reached over to take the move back.

"Hey, you know it's touch move, besides you let go of the piece, you can't re_take the move," I said.

"You want to win that way. Go ahead take my Queen and F*** Bobby Fischer." He knows that I love Fischer and he used his name instead of the word "YOU".

 I took his queen and we spoke nary a word after that. I had a mate in several moves and then we heard., "Come and get it, dinner is on!"

Immediately he got up and left the room. We didn't play at Thanksgiving, Christmas or New Years. I know we will never ask to play again.

I thought Fischer loved playing white because he liked open, aggressive chess.

I like playing white only for about eight moves hoping I can spring a trap or something but after that I hate that I have to use my knowledge to play the game and I try not to lose.

When I play black I just respond to whatever white moves, hoping I can take the initiative. There is an advantage playing white since it has the first move.

               It's also Psychological.

Denver - LOL - sorry he was a sore loser.

Agreed !
