playBunny: I used to do that at ItsYourTurn. Compiled ELO ratings by collecting the results of all tournament matches. I wrote a script -- I think it was in Perl -- that did it all automatically. That got me banned from IYT for a short time for using too much of their bandwidth!

Hrqls: If you're familiar with Html then it's pretty easy. Fetch the page (using a browser control), find the table and extract the records (standard but possibly messy string handling). Now you've got the data and you're in familiar territory...

题目: Re: top 100 in all 6 types
TC: the easiest way to do it would be to determine how many players are in the top 30% for each type, then go to the list with the least ranked players, which would be anti-backgammon ... go through the top 30%, click on the players profiles and check if they are within the top 30% for each type .. if so .. then add the name and ranks to a spreadsheet ..

at least thats what i did with the top 100 (although i checked all the names in the crowded top 100 ... which was just a random type to start with :))

Hrqls: What you think for this hard work. Direct copy and paste the mentioned pages to the spreadsheet (like Excel) and then work for calculation, for the first samples?

Then we need update period and update place to fix them. If The Big Boss (Fencer) shows interest for it, our work may be lighter.

Hrqls: In that game you wouldn't care about gammons. It's such an overwhelming loser that you'd drop it like a smelly dead cat and be grateful for your opponent's mistake.

Your opponent should have kept the prime and hit you as soon as possible in the hope of being hit as you come off the bar and, in turn, hitting your blot on 4, or otherwise picking up a companion for your trapped man. That would increase his gammon chances considerably. Even without hitting you, it is, as grenv said, too good to double.

Hrqls:
Your study is good for the top 100 of all gammon types. But as you know, players of the gammon variants are not in the same quantities. (Click to http://brainking.com/en/Ratings for the latest members quantities.)

For example, today:
Backgammon: 895
Nackgammon: 251
Anti Backgammon: 61
Race Backgammon: 253
Crowded Backgammon: 209
Hyper Gammon: 521

The rating and BKRs self also goes up and down in some periods.

My offer is for the sampling method:

If we get the same percent for these games from their total players and then calculate the ratings and the BKRs for the players; we can get better performance results.

My offer is for the sample percent is: 20% enough good to be able to see the Masters of Gammon variants.

If this offer is acceptable generally, we can begin to calculate the following input numbers:

Backgammon: 895 x 0.2 = 189 players
Nackgammon: 251 x 0.2 = 50 players
Anti Backgammon: 61 x 0.2 = 12 players
Race Backgammon: 253 x 0.2 = 51 players
Crowded Backgammon: 209 x 0.2 = 42 players
Hyper Gammon: 521 x 0.2 = 104 players

题目: Re: 4&5 or 3&6
Hrqls: One way to find it out would be to go through the missing rolls and add up the misses for the roll after that, counting the misses after non-doubles twice. I'm sure someone has a quicker way to figure it out.

grenv 
题目: Re: cube action
Hrqls: What do you mean "you are not sure if you would have been gammoned" ? Of course not, it's a dice game.

There is, however, definitely a chance (probably a little under 10%) that you will be gammoned.


and yes, i agree 3&6 is better if you don't need to get out right away.

is 3&6 better or 4&5 when you might have more than 1 chance ?

frolind 
题目: Re: 4&5 or 3&6
Hrqls: Yes, you are correct. I was only thinking of when you have to get off in the next roll. If you have more than one chance, then 5&4 is not as good as 6&3. Sorry for the confusion. :)

Hrqls 
题目: Re: cube action
grenv: i am not sure if i would have been gammoned .. i had most of my pieces in my home .. i would have probably escaped when he opened his 5 and 6 position .. leaving me with an average number of about 5 or 6 rolls to bear 1 piece off

but there was still a chance

i wouldnt have doubled yet in his position .. as it would have wanted to see if i could be lucky for a gammon .. and i would not .. then i would double a bit later anyway

15. 十二月 2005, 21:03:20
grenv 
题目: Re: cube action
Hrqls: This was not a tough decision: Drop. If you accept you will probably lose and may get gammoned. I'd say if you played 10 games you would win once, be gammoned once and lose without being gammoned 8x.

In fact I wouldn't have doubled if I were your opponent and played for the gammon, I think his position was too good for a double.

15. 十二月 2005, 21:01:18
Hrqls 
题目: Re: 4&5 or 3&6
grenv: *nod* i looked at the dice
3&6 bear off with: 3+3,6 & 4+4,6 & 5+5,6 & 6+3,4,5,6
4&5 bear off with: 3+3 & 4+4,5,6 & 5+4,5,6 & 6+4,5,6

both have 10 rolls to bear off (out of 36 possible rolls)

but! there might be a difference with the left over in case one isnt able to bear off .. for example one rolls 1+2 .. then the position 3&6 will bear off the 3 piece leaving a single 6 piece .. where the 4&5 position cant bear any pieces off leaving 2 pieces on the board closer to the finish

so 3&6 might be better in case one doesnt bear off at the first roll ... but i am not sure about this one

any thoughts ? ;)

15. 十二月 2005, 20:49:05
grenv 
题目: Re: 4&5 or 3&6
Hrqls:

3&6: 27.8% chance of going out
4&5: 27.8% chance of going out

They are the same.

Not always the case. For instance let's say you have 7 pips left:

2&5: 52.8%
3&4: 47.2%
1&6: 41.7%

So 2&5 is much better.

题目: cube action
another cube action which i found rather tough .. i declined because accepting would make it a 4 point game in a 5 point match ... creating a crawford game if i would lose without being gammoned .. i didnt like that and think my chances are better by me needing 5 points and my opponent only 3

any thoughts ?

what simple rule do you use ? (if i dare ask ;))

(btw i lost the game because my opponent rolled double 4 for his last 3 pieces :))

题目: Re: 4&5 or 3&6

would you rather have your last 2 pieces at 4 & 5 or at 3 & 6 ?

each option has 10 out of 36 rolls to finish .. but which is the best ?

(btw it happened to me in a game, but i made the move already .. i went with 3 & 6)

pentejr: *nod* i am playing crowded with him now .. and told him about it ... he will soon be in the top with crowded as well (only needed 3 more games last night) and only needed 6 more games of anti (which takes a bit longer though :))

i know of the aversion of some players against anti ... its a great game though .. requires some different tactics and tricks ... but fun ones .. the disadvantage is the high number of moves thats needed to finish a game though
(with the cube it can be done faster ... but not always ;))

i will try to make a similar list without anti somewhere next week .. i am not sure if i will have time though

a better list would be to put everyone on it who is in the top 10% (or another %) of the list .. as there are a lot more people on the backgammon rankings than on the other types :)

i see the types as 4 groups :
back & nack
race & crowded
hyper
anti

题目: Re: Spacing in messages.
Hrqls: The workaround is to use underscores. (Dots don't work as they aren't a full character width).

Ideally you should be able to use &nbsp; to get additional spaces but there's a bug in the message code which (unpredictably) ruins the layout of anything long so &nbsp; is only useful when inserting a couple of additional spaces.
