Well, White moves first, so White has a slight edge at the beginning of the game. Also the opening book would be a factor, as would the horizon effect during engine calculations.
I did a quick 50-game demo with Stockfish DD versus itself. The result was 38 draws, 10 White wins, and 2 Black wins.
thx for the reactions!
what do you mean with 'the opening book would be a factor, as would the horizon effect during engine calculations.'
that white has an edge at the beginning,is that a mathematical fact, or is it just statistics?
And let's say we change some rules: white plays to win, and black just not to loose.
White has to move, but black can choose not to play a move, unless it would kill him.White wants blood, black's just a lazy guy. What would be the result?
Regarding the opening book - Some books try to gain an advantage, while others strive to be neutral (no advantage). So a neutral book would tend to produce more draws for an engine playing against itself.
Regarding the horizon effect, I guess what I was trying to say is that there is some randomness in the engine's strength due to the fact that the engine can only look so deep in a given amount of time. After the engine makes its move and the opponent starts calculating its response, the opponent will be able to look 1 ply (a half-move) deeper, so it might see something (either good or bad) that the other side didn't see.
"that white has an edge at the beginning,is that a mathematical fact, or is it just statistics?"
I'm not a mathematician, so I don't know if it's a mathematical fact. But I do know, "It's a fact, Jack!"
Regarding changing the rules - I don't like changing the rules...Let's please not do that. But I will say that I think you're asking two different questions here. If Black is not trying to make the strongest move, then obviously it will play weaker. However, if Black IS trying to make the strongest move, AND you also allow Black to "pass" on a move if desired (in computer chess this is called null-move), then I think this would increase Black's strength.
It depends on:
1). which colour it makes a bad mistake (or a "sufficiently big" aggregate of small mistakes) with first
2). whether it spots this as the other colour
Allowing a null-move would radically change the nature of Chess as anything that related to zugswang would be thrown out of the window...

Agreed. To clarify, I interpreted the question as allowing Black the option of null-move, but not allowing this for White.
You would need to focus on one opening or position to get a concrete result. Lumping Sicilian games in with Ruy Lopez games by itself would have too much variance. TCEC limits its games to commonly played games (no grob games or sodium attacks from what I saw).
What is your goal in playing computer against computer?
Hi all chess-lovers. A litlle question, the most of us probably did it once or two, playing against him/her self. What is the result if a computer plays against itself? Shouldn't that be remise?
