I played 13 races against him (Chiryu007) yesterday:
Sebenco that he hosted himself: I quickly had a nice lead thanks to a turbo,
then he left the race on the 2nd lap... I found it strange but well.

Then I joined a 12 races tourney, with 8 players, he was also there.
I won the tournament (93), but he managed to win a race, and when he didn't,
then he was a close 2nd or 3rd most of the time.

Then he congratulated me saying that i was good, and i told him he was also
good, and to keep playing, so no problem here!
Looks like he's on my side
