What is this thing called as tie breaker ????Im  having the highest tie breaker in my tournament ! is that a gud sign or a bad sign ?? plz help 

Hmmm, I think this one was asked recently.  Check here for your answer though.  The short version is that tie-breakers are exactly what they sound like - a way to break a tie between players with the same number of points.  The higher the tie-break, the better!

Thx, but how to earn tie breakers ??

If your tie is too long and knocks over the chess pieces they have a thing that breaks it for you.

U can't earn them. the best thing u can do is win as many games as possible. depending on what other ppl in ur group get, this will affect ur tiebreaker.

 I quote, from the linked help file:

If 2 players in a group have the same score then both will advance. Tournament Directors can choose to use an additional tie-break method (we use the Neustadtl score) which factors in the strength of the opponents. If two players have the same score and the same Tie Break score, both will advance.

Then Wikipedia goes on to describe the Neustadtl system:

The Neustadtl score is a scoring system often used to break ties in chess tournaments. It is named after Hermann Neustadtl, who proposed it in a letter published in Chess Monthly in 1882.  It is often called the Sonneborn-Berger score, though this is something of a misnomer, since William Sonneborn and Johann Berger were actually strong critics of the system; they proposed their own tie-breaking system which was never popular and is not used today.  A player's Neustadtl score is calculated by adding the sum of the conventional scores of the players they have defeated to half the sum of the conventional scores of those they have drawn against.
