Emne: Re: Pieces on the bar in Crowded Backgammon with the double cube being used
Aganju: Hmm, it seems some of what you say is true. I've known that he is less interested in Backgammon, or at least appears to me to be.

I think the pieces on the bar at the start of the game in Crowded Backgammon and I suppose Backgammon Race, though I've not played that game, that do not have to be brought in on the next turn should be marked or segregated in some manner so as to differentiate them from pieces hit later in the game. This would facilitate playing the game as it would be obvious when returning to a game that you have a piece hit, instead clicking to move and wondering what's wrong with the site or game.

And a piece on the bar no matter how it got there should give you a backgammon if you can bear off all your pieces and your opponent has not taken one off.

Emne: Backgammon Tourneys
Modifisert av Aganju (27. desember 2013, 04:26:11)
It seems the majority of people create Backgammon tournaments with the setting '1 win match', be it in round-robin or 1-1 play. That may be the best way for most games, but for BG I think the better choice would be at least '5 points with doubling cube' or even higher.
The reason is that BG has a significant factor of luck, and even as the world champion, you could lose a match against Joe Schmoe if the dice roll unlucky - but not so easily a match for 5. Whatever, anyone who seriously plays BG, knows what I talk about.
For me, this discourages me from joining any of those tournaments, especially when they are 1-on-1, as it is mostly luck deciding who wins the tourney.

Here my question: Am I alone with that opinion, and all others are happy with how they are offered?
if yes, then fine. I can always make tourneys the way I prefer them if I want. No hard feelings.
If no, then I wanted the tournament creators to know that; so they can create them as '5 point with doubling' (or more) and get more players. Maybe they are just not aware of it?

Emne: Re: Backgammon Tourneys
Aganju: Not only do one pointers have a large luck element, the rating system grossly penalises the stronger player. Players who value their rating should avoid them unless they are the underdog.

As for whether you're alone in the opinion, here's one player who agrees and takes it to the other extreme. ;-)

Emne: Re: Backgammon Tourneys
Aganju: You are right about the match length. There is a reason why serious BG tournaments go for, typically, 21 points.

But the dice rolling of BK is questionable, to say the least. Serious play of Backgammon - or any other game with dice - is not possible here.

Thom27: 'Serious play of Backgammon - or any other game with dice - is not possible here'
Why is that, in your opinion?

29. desember 2013, 16:03:09
Thom27 
Emne: Re: Backgammon Tourneys
moistfinger: The first reason is: there seemingly is still the bug causing to repeat the same dice roll with too high probability, when you go from one Backgammon game directly to another (with "submit and go to next game of this type").

Second reason: many players have the impression that the dice "just feel wrong" on this site. Me too. (That can be mistaken, of course; it is difficult to tell without statistical analysis.)

Third reason: there have been other bugs in the past, concerning dice rolling. At least one was proven by statistics: the first and second roll in a game have too often been equal. This bug is removed, however, but it shows that the implementation of the dice was erroneous from the beginning, and it still is not ok yet (see first point above). That thing seems overly complicated or inherently bad and therefore difficult to fix.

Fourth and most important reason: the random number generation is not documented, so that the players don't know what they are using. It is as if someone brought a bag full of self-made dice to the Backgammon world championship and claims these are better than any other existing dice (or at least not worse), and the tournament director decides to use them without testing. I think you agree that this would be a bad idea.
It is possible (and not very difficult) to create a cryptographically secure random number generator to roll the dice, that uses for every game a secret key which can be published after the game is over, and the generator code can also be public, so the players know the mechanism and can test it for it's general quality and as well for it's correct implementation, because once the key is known, the dice rolls can be re-calculated with own implementation of the generator. The rolls are however not predictable as long as the key is secret.
Such a method would IMO be required for serious online play of games with random.

Aganju 
Emne: Re: The terrible RNG
playBunny: You are right of course. It does not make it easier to win, if you cannot predict the 'bad' rolls. However, if the randomness is not good, it slowly makes a different game out of Backgammon - for example, if there are less doubles, or incorrectly often two doubles in a row, you can adjust your strategy to take advantage of it. It is still a fair game, but it is not 'standard' Backgammon anymore.

However, I found a high chance of reproducing your opponent's roll by clicking in specific sequences. So when the game comes up, and he had a 5-5, and I want one too, I do that sequence of clicks, and have a higher-than-1/36 chance to get it too (it does not work all the time, but maybe 1:3; still, pretty useful feature); whereas if he has 1-2, I will not do that typically.

I suspect that any such effect would have to be quite sizeable for it to change people's strategy. Their strategy can be highly resistant to change even when you teach them to improve their game.

I'd say that if you're doing that then it's still standard backgammon but it's no longer a fair game. :-/

Thom27: i always am fond of your second reason :) ... but you probably also know that humans tend to remember bad things more than good things .. therefore there always seem to be more bad rolls than good rolls

your third reason: i think i was the one who came up with that, and i did come up with it by counting all games and record in which the bug happened and also in which games it didnt seem to happen, after that i let some friends on here know about it to verify my thoughts, and after that i posted it on the board to ask for more statistics ...

to claim any random number generator is bad you need to collect statistics, without statistics you will only have your second reason and that one doesnt really count

so, could you please write down your games and keep the statistics (all games on this site remain here forever, so you can show it at any point in the future to everyone) .. once your have the right statistics we can discuss it for real

Emne: Re: Backgammon Tourneys
moistfinger: I have played on Dailygammon for some time, and didn't notice any strange or unnatural behaviour of the dice. Also, they have documented their dice rolling, and this method, if implemented correctly (bugs are always possible of course) should give fair and statistically correct rolls.

Thom27 
Emne: Re: Backgammon Tourneys
Hrqls: You are of course right that statistics is required, but it is a) considerable work, and I don't want to bother if fencer seemingly is not interested anyway, and b) it is not always possible. One can't tell afterwards in which order the dice in different games have been rolled. So there is no way but recording during play. I once tried to create a tally sheet counting the equal and the different rolls when going from one BG game to the next, but I quickly lost track ... and see point a) above.

Ananju mentioned there is a way to reproduce the opponent's roll with higher probability than normal. This might be proven by analysing many old games, but if only few players know about this method and use it only in few situations, the statistical effect is very small and difficult to detect.

It seems we just have to accept the questionable dice rolling here. We may play here for fun, but for serious play one should go elsewhere.

That's not so. You have to accept it or go elsewhere. I, we don't have to do anything of the sort until you prove your case. It's like someone saying that they've see seen the Yeti but have no tissue sample, no photo, not even a map showing how to get to where you saw it. The Yeti may exist but it can only be treated as an interesting but unconfirmed story. Aganju claims to have met the Yeti and had a chat with it . That makes it more interesting but the story still needs more to become real.

Emne: Fevga rule
Modifisert av Carpe Diem (14. mars 2014, 08:47:42)
There was some discussion a few weeks ago on the main Brainking board about this rule that isn't software enforced:

  • It is allowed to build a prime (six consecutive blocked points) anywhere else (not in the player's starting quarter), but if opponent has collected all his checkers onto the one point behind player's prime, the player must unblock a point in his prime to allow the opponent a chance to move.

I'm involved in a game where all of my stones but one are behind a prime - the other stone is on my 1 spot, so also can't be moved. I would think the spirit of the rule would mean that my opponent should unblock, but since I haven't collected ALL of my checkers behind his prime, I can see how a literal translation would suggest that he doesn't need to unblock. Does anyone know with certainty how this should be handled? I'm not especially concerned with this game in particular - I'm well behind and thus unlikely to win, and he can't block me for much longer anyway. I'm mostly curious as to how the rule should be interpreted.

14. mars 2014, 19:21:36
Aganju 
Emne: Re: Fevga rule
Carpe Diem: i think it should be interpreted 'if you cannot move any more with any dice roll, he needs to open up'. But I have never played Fevga over a real board, so maybe someone who has should answer this.

Emne: Re: fevga rule
Pedro Martínez: Again, it is the interpretation of the rule. I have one checker that was able to pass her prime (6 consecutive pieces) and has moved as far as possible, to the "1" on the bottom of the board. All other checkers are stacked on the 2... there are no possible moves to make at this point.

I think what you are getting at is that one checker was allowed to move as far as possible so now it is ok to block the rest, because the rule does not state "collected all [REMAINING] checkers..." so this is where different interpretations come into play.

Does anyone know with certainty how this should be handled?

The same rule is given on Backgammon Galore as "Limitation on primes: You may not build a prime (six consecutive blocks) in front of all of the opponent's checkers; at least one opposing checker must be in front of your prime".

The rule is about building a prime. So if a certain move would inappropriately complete the prime then it is illegal. The rule prevents the move in question.

The rule whose spirit you're suggesting would be about forcing a player to break a prime that's already been made. That's a very different thing and may not actually be possible at the point at which it becomes applicable.

The rule would be have to be something like "If your opponent cannot move and all their pieces behind the prime are stacked on the single point immediately behind then you must open a point within the prime at the first opportunity". This rule would force the given move or small set of moves that break the prime.

This is unlike the prevention rule in several important ways, as can be seen above. The similarity is that they are both concerned with not allowing a prime in their respective contexts.

To be honest I'm not sure what the spirit of the original rule is unless it's to give the trailing player more chances to prevent the prime happening in the first place. Each turn that the leading player cannot close the prime is an opportunity for the trailer to claim that point themself and retain a link, however tenuous, to the forward territory. Once the prime has been made then it's tough buns, they didn't make it.

I think a rule that extended the spirit of the rule as it appears to me would have to ban primes altogether - and that's quite a game changer.

cd power: Are the "official" rules for the game somewhere on the internet? Just kind of curious on the different "interpretations" of that rule.

For example, in the game - lets say that ALL your pieces except for 1 is already past the prime on the "1" space on the bottom of the board, and only ONE piece is trapped by the prime - would you still interpret the rule the same way?

".... but if opponent has collected all his checkers onto the one point behind player's prime, the player must unblock a point in his prime to allow the opponent a chance to move."

Hi
i'm the meaning this is an error. in the game bellow the system wants me to move 1-6 and 5-7. But I wan't to move bar-5 and 5-2 but the system forces me to move 1-6 / 5-7.... Is this an error?

I'm asking 'cause usualy when a game has an error i only need to contact fencer and he deletes the last roll or whatever, but i didn't get an answer since 2-3 days... so am I maybe wrong and it is not an error?

~~ As for points - it always seems to me that in a simple game, you get the same points whether you just win, or win with a gammon, or win with a backgammon. That's rubbish.

That's how it works with proper backgammon, ie. the version of the Elo formula that FIBS, DailyGammon and various other sites use. It's getting to the match length and the win that matters./ How you do it doesn't count. Same as in tennis or other sports. You may get a pat on the back for winning by a country mile but you don't get any more of a win.

~~ As for "match", in super-rugby, the losing team can still get bonus points for scoring 4 tries, or for losing by less than 7 points.

Ah, that's interesting. Sounds like we need super-backgammon! :-D

I had been going to say that rating points aren't in any way a reward, even if it's nice to get them, but that they contribute to a rating which is intended to be predictive - that is two ratings will give you each player's winning chances in a match between them.

That's still true (for the proper formula but not for the BrainKing version) but I was then going to say that it's match wins that go into the formula and give you those percentages and the games don't matter. However, I had second thoughts. Why, indeed, shouldn't 11-10 count as less of a win than 11-0? After all, it's reasonable to at least suspect that the player who scored 10 knows a bit more about the game than the one who scored nothing.

I think the answer is that the backgammon formula, based on matches, is nice and concise as it is but could become rather complicated if it tried to take into account the games as well. I'm no mathematician so I don't know what would be required but it would certainly be more complicated with both scores involved rather than just the binary won/lost. It's not even certain that it would be more predictive. Mind you, once you had such a game-based formula (and a large number of matches), it would be straightforward to test.

It's certainly an interesting idea.

.

Getting back to that win/gammon/backgammon. It really depends on whether you're playing a money game (where the final score actually matters because it multiplies the stake; so a backgammon win in a $10 game would therefore be worth $30) or whether you're playing a 1-point match, in which case the extra 2 points are superfluous.

It matters because if you win a gammon or backgammon in a 1-pointer then you've possibly played badly. Gammons and backgammons are usually achieved through taking risks that reduce your winning chances. As such they get flagged as errors by analysis. If you only need 1 point then you should play to win 1 point and not more. (If it happens by chance that's fine but no extra risks should be taken). I therefore wouldn't give credit for exceeding the match length, whether it's a 1-pointer or a 25-pointer. But a money game is arguably worth more. That rating formula that takes games into account might also be able to treat money games differently rather than as 1-pointers.

playBunny: quote "The real question is: why do the same points apply when you win or lose an 11-point match or 1-point match???"

I have wondered about this. As I used to only play single games, the rating system here would discourage people with higher ratings than myself from playing me. When I started to play matches, I noticed that higher rated players were more likely to play me, but only if we played longer matches. I presume this was in part to account for the skill supposedly shown by the higher rating and the rating awarded for winning the match.

So I got to thinking, why doesn't Fencer have a weighting system for the matches? With a single game being lessened the most and then a steep curve that begins to level off as the number of games in a match increases?

An example; It seems like a 100 point difference in rating has the rating change 11 for the person with the lower rating if he wins and 5 if he loses. Seeing how even the world champion can be beaten in a single game it is obvious that such odds are ridiculous for a single game, but certainly seem fair enough in a 15 game match. How hard can it be to devise a scale for the odds and ratings to make it worthwhile to play with anyone?

As I only play on this site, I have to wonder if the other sites you've mentioned playbunny already do something along these lines?

playBunny: In your example, what would a single game be worth and also a fifteen game match with these same two players?

What does 4 * Sqrt mean? Four times the square root of something? The match length? Yes 4 × √5 = 8.94. OK, so for a single game it'd be 4 rating points divided up by a formula figured out from the players' ratings? Since 4 × √1 = 4? And for a 15 game match, 15.49 ratings points 4 × √15 = 15.49? Interesting, and this is a weighting scheme. I am thinking that the difference in the players' ratings is a fairly accurate way to determine the percentage of points awarded from the match weighting as it is used here, though without the match weighting. This is not quite how I was thinking of weighting it, but it seems like a good plan and is lots better than what we have now.

This method seems to make the length of a match much less important to the higher rated player than the method used here. Or am I imagining this?
