Round 1 Pairings 2018

Should there be a tie-break if the ending result is 1-1?
Maybe an armageddon were who is white is forced to win if it is draw black wins.

I won't be able to play on Saturday. I am at an otb tournament. for Friday, Saturday, and Sunday, and Monday. How do I do this?

I've literally tried so hard to get on at the same time that my opponent does but it never happens (sent a few messages only responded once)... so I honestly don't know what to do...
