Hi Nick,
good morning,

some brotherhood matches will occur, as a natural result of the Swiss tournament.

Already in round 3 there are 5 matches facing the same participant with different Elo setting:
Honey X5i 1800 vs 1600, and 1000 vs 2000
Chiron 5 1200 vs 1000
Arasan 24.2.1 2000 vs 1800 and 1200 vs 1000

Cheers,
Eric
