Tournament tie breakers

  I am fairly new to organised chess, and joined a couple tournaments for the first time. I am curious about the tie break rules.

  I won all 10 games in my first round, as did an opponent in the second round.  We are both doing well, and tho I beat him once, he is looking good in the second match.  Supposing we split our 2 games, and win all others (way too early to tell realy) we will be equal in games, and equal in tie-break points!  ( 15th Chess.com Quick Knockouts (1201-1400) - Round 2).

  How will the win be decided?

Thanks for any input; TAHU
