Black all the way ....

I had the black pieces in 6 from 8 games now, thats just too much.

that's not abnormal yet, and it hardly matters for blitz anyway

It doesn't matter when you play 2100+ players all the time? It feels as if it matters I can tell you.

it is not martingale on roulette that you were playing...

Advantage in white at standard is +0.3. That means nothing in blitz and at 2100 elo.

"Good luck to everyone, enjoy the games! I usually don't play a rematch. One opponent, one game, no matter if I win or lose or draw."

You already said it in your profile.
- Enjoy the games!
- One opponent, one game, no matter...

What if your opponents got black in several games?

I personally love playing with black, but that's just me...

Have fun anyway and enjoy the game!

Playing white or black doesn't matter.

Go to the analysis board, play a couple moves in an opening.

Watch how it hovers around 0.0.

An advantage of +0.3 as white while starting means absolutely nothing.

Your total score is:
White 2,052 games
Black 2,039 games

The pairing system tries to balance it, therefore you get black with a higher chance.

You have to go in tournaments to play people differently rated than yourself.
