How to read scoring

Sort:
Alex201807

My son recently did two tournaments, I wonder who can explain to me how to read the scoring:

The scoring for the final is like below:

What I don't understand is the B- and U-, and what's the meaning of the last two columns, how are they generated? How the pairing is determined for each round?

Thank you.

I think the “B” means a player took a bye round. No idea about the “U” though.., Unrated maybe??

The last two columns look like some sort of rating. I dont know what the B and the U are for, maybe a bye. It looks like player 3, the U, lost to player 11, the B.

U is unplayed, perhaps a late entrant. B is a full point bye for a player unable to be matched, since there was an odd number of players.

The last two columns are tiebreaking info.  Tbrk (H) is head to head tiebreaks. (See link below.) The last column is the player's performance rating.

Assuming a swiss system, pairings for the first round match the top rated player against someone halfway down the table.  So 1 versus 7 in a 12 player tournament. The second highest against the next player further down the list. 2 versus 8 and so on. In the next round, players are grouped by round 1 results.  Let's say 4 winners; 4 draws and 4 losers. Winner 1 plays winner 3. 2 plays 4 and so on.  Next round those with 2 points are matched, etc. Players should not be matched twice. Colors should be alternated.

By the end, a clear winner is determined.

Thank you all for the replies. How the earned score is determined then? for example, after a tournament, a player's score can be up or down, any formula I can calculate myself?

 

Thanks.

Do you mean score or do you mean rating? If you mean score, then it's simply 1 point for a win, 0.5 for a draw, and 0 for a loss. So 3 wins, 1 draw, 1 loss, would be 3.5/5. If you're talking about the rating adjustment after the tournament, then that's something else, and it would depend on the opponent's ratings not only the results.

Thank you, James, yes I meant rating, I understand it must depend also on the opponent's rating, an the result, I am thinking there should be some rule that a tournament can refer to in order to calculate the new rating, right?

I believe "u" means "unpaired." In many tournaments, you can arrange a 1/2-point bye in advance if you know you won't be able to play that round. But is you wait to long to say you won't be playing, you will be unpaired and get a zero but not a loss!) for that round

The tie breaking columns are too hard for me!

and I am pretty sure h means you took a bye because you wanted to
