In exceptional cases the organising committee has the right to permit a chessplayer to play in a higher tournament than his/her FIDE rating indicates.
In case of a tie of 2 or more participants, the prizes are divided according to the Hort system.

Explication of the Hort System for the prize distribution.

As mentioned in the regulations on Internet the prizes in cases of a tie of two or more participants will be divided according to the Hort system. The following example will explain this system.
Suppose 4 players share the same place. The four prizes are as follows1st $10000, 2nd $8000, 3rd $6000, 4th $4000
We have to split $28000. We split this amount in two equal parts, of each $14000.
The first part will be split equally. Each receives $3500.
The second part will be split according to the ranking after tiebreak.
#1 receives $3500 + $5000 = $8500
#2 receives $3500 + $4000 = $7500
#3 receives $3500 + $3000 = $6500
#4 receives $3500 + $2000 = $5500

In all tournaments the number of prizes is not more than that shown in the tables above.

Tiebreak systems:

For tournament A1, A2 and B:
1. The number of games played with Black. Byes and forfeited games will be considered as games played with White.
2. The average of the opponents' ratings minus the highest and the lowest rating.
For Tournament C:
1. The Buchholz score
2. The Median Buchholz score: it is the Buchholz score reduced by the highest and the lowest score of the opponents.

Seniors and Juniors:

A player will be considered a Senior when he was born before 1-1-1948.
A player will be considered a Junior when he was born after 31-12-1989.
Girls born after 31-12-1989 will be considered as Women players.

Special Prizes:

There will be also special prizes for the best performance among seniors, women and juniors in all tournaments (total 5000 USD).
This year, for the first time, there will also be a prize for the best result shown by an unrated player in section C.
Only one prize can be awarded to a player (the highest one).
The exact distribution of the special prizes shall be published after the second round of the tournament, when the numbers of seniors, women and juniors and the ratings of the payers in the festival are known.
Attention is called to the fact that for such prizes to be awarded there should be at least 3 players in each of the above categories.

In case of a tie a special prize is awarded to the player who has the best auxiliary score.
