Summertop: This is because it was a double round robin. *For each game you won* (as there was no draw), add the number of points of your opponent (that means, count twice the points of the opponents that you beated twice) and you will get 29.
Probably the explanations were thought with a simple round robin tournament in mind.
What counts is the total number of points earned by the opponents you beat. You and Uil had the same record except that you won both games from grafzahl while Uil went 1-1 against him; and Uil won both games from Seravajan, while you split with him. Grafzahl finished with 5 points, and Seravajan finished with 7. You earned 17 S-B points for your games against these two, while Uil earned 19 S-B points. That is why he has 2 more S-B points than you do.
Of course, it's not your points that matter, but the ones of the opponents you beat in the tournament. So, if you won those 3 games to opponents that ended up with 2, 3 and 4 points respectively and the draw was to a player who has 1 points, your final SB will be 2 + 3 + 4 + 1/2 = 9,5. Hope it's better explained now
Summertop: The "points" are the points you end the tournament with. If you win 3 games and draw another, you'll have 3 and a half points. These are the points that are used to calculate SB score.
harley: Yes and no...I understand the concept. But what "points" are added to get the actual S-B score? In my tournament, I didn't readily see anything that added up.
S-B is an abbreviation for Sonneborn-Berger system. It is used to specify an order of players with the same number of points and is based on a theory that points earned with a stronger opponent are more valuable than with a weaker one. The S-B value is a total sum of points of opponents who lost the tournament game with the player and half points of opponents who drawn the tournament game with the player. Only if two or more players have the same number of "normal" and S-B points, they share the same final order.
Summertop: Oh, wait...it has nothing to do with losses. He beat a higher ranked player. Whereas, I beat a lower ranked player. But then again, playing each other...didn't offset the other games. I would still like to know what "points" are added up, though.
Can someone explain the Sonneborn-Berger system as implemented in Tournaments? It basically says it is the sum of points of the players that I beat (1/2 points if drawn). And, points earned with stronger players are more valuable than those from weaker players. What "points" are actually used to calculate it?
In the link provided for a tournament I am in, I and Uil tied in points. We played each other twice and split the games. Since he is ranked higher (better player), shouldn't I have I higher S-B score? Also, we each lost one more game. The opponent I lost too had a higher rating (better player) than the one Uil lost to. So again, shouldn't I have a higher S-B score? After that we each beat the same opponents... Uil, is a great player and I don't really care about the outcome. I would just like to know how it is calculated.
Maybe simplify...if we both beat every other player, but split the two games (we each won one). Who would have the higher S-B score? and why?
Bry: No. What you buy, you get. It's up to you how you use it. You can spend Brains to extend your membership or purchase a membership for another user. You can save them for a later use. Or you can pay a tournament entry fee with them and hope you will be one of the winners and win a thousand or two. But, as I always say, it's just an option and everyone can use all advantages and features of BrainKing without any Brains.
Fencer: So, in theory, if I buy 150 Brains at 5 Euro, I am only actually buying 105 Brains for 5 Euro, because 30% of them will "disappear" if I use them?
Thank you playBunny, Vikings, Pedro Martinez, Pythagoras, and fubster! I have had trouble understanding this but with all your versions of explaning it, I think I finally get it! :) I appreciate your help! I have to do some reevaluating of those tournaments I sign up for when I'm needing to do silly things like SLEEP! lol
Mary Jo: In that kind of game the 1 day is the total amount of time in which you can play moves. Let's ignore the bonuses for now and just imagine a couple of those sand-filled timers. There's one for each player. If the sand runs out then that player lose the match. Unlike the ordinary sand timers, though, these ones don't get turned over. Rather they get switched on and off. Yours is losing sand all the time that it's your turn. When you move yours stops and your opponent's starts losing sand. So, there's not a heap of sand per move but for the whole game.
Now let's consider the bonuses. This has the efect of topping up your sand each time you move, by 3 hours-worth in this case.
Looking at your game it says that you played 9 moves. Your timer will have lost the sand between each move - the period from when your opponent moved to when you did. If you add all that time up then that's more sand than there was available.
So how much sand did you have? 24 hours (the initial 1 day) plus 9 bonuses of 3 hours, giving 51 hours in total. At the point that your opponent made his last move you must have had only 4.5 hours of sand left .. and hence the timeout.
Mary Jo: it is using a fisher clock which means that you have 1 day total to play the whole game with a 3 hour bonus, to make it simple for example if you wait 8 hours to make your move you would have 16 hours left plus 3 hours for your bonus for a total of 19 hours to make your next move, if you wait 5 hours when it is your next turn to move you ould have 14 hours left plus 3 for a total of 17 hours to make your next turn,. these games can catch up with you when you have to work or sleep so its a good idea to play these games first when you are on-line to add up the bonus time
Mary Jo: If you moved 1.5 hours before the "deadline" on your last move, you had only 4.5 hours left after your opponent moved. If you moved in the last second before you'd time out, you'd have only 3 hours for your next move. I think it's quite simple.

Mary Jo:
When a game has:
Time for game : Time: 1 day, Bonus: 3 hours, Limit: 10 days, no days off
Then it means that:
You have 1 day = 24hours to play the whole game and not the move.
That means: if your opponent plays a move and then 2 hours later you play your response, you will then have 24-2 = 22 hours to play the game.
If your opponent makes another move later and you play after 8 hours(from his response), then you will have 22-8 = 14 hours left to play the whole game.
But that with bonus = 0. With bonus = 3 hours like here, after your move you will have 3 hours added to your time left for the whole game....
Limit = 10 days, just declares that if you play many moves quickly and the bonus is not 0, so your time for the whole game increases, this value can't go above 10 days....
Mary Jo: I'm finding it difficult to keep up in this set of tournements too. You have one day to start with and 3 hours gets added on if you move within a certain time. but its not necessarily one day a move as i found out lol.
it's a game that has a 1 day time limit. I last played on 2/3 @ 1748 and my opponent played 2/4 @ 0237....then I got a message that I lost my game and timed out on 2/4 @ 0709. That was only about 13.5 hours since my last move and only 4.5 hours since my opponents last move. What am I not understanding here? lol Help!

Stevie: It was just the Reversi games! If you have another case or even sign or even any other small evidence then just give it or stop throwing things in the air....! But i don't care anyway if you accuse me or not because i know the truth and i only care about non-weakies statements....

Stevie: No, i used my program at Reversi 8x8 because i was beta testing it.....You can't just understand/believe it right?
After the game you said: Do you use Zebra?
I replied: No i use my own written program that is trying to solve the game with 28, bla,bla,bla....
Do you think that, i would tell you that if i wanted to cheat? Also i proposed you and Fencer to delete my game against you and actually against all my other opponents.....
Once again my honesty(by telling you the truth) had the opposite result as i expected.....
Pythagoras: for sure, and Im sure Filip would get more people willing to fork out 280euro for that black/gold topped rook than would fork out for a maharajah..... especially as neither gives you anything extra other than a diferent iconic status..
BTW, aint you the guy who used programmes cos you didnt like to lose?
