Temo: double capture of grab the 5 position ?
whats more important ? capture 2 pieces (and leaving a single on the 5 position) or secure the 5 position ?

example

i chose to secure the 5 position as you can see (and hope to capture the piece on 7 with my next move)

(i hope basplund doesnt mind me posting this here as i already made the move, if anyone thinks i should not post this yet i will remove it)

grenv: i would love an analysis as well :)
i think you are right .. i tend to play too defensive lately .. trying to turn around again :)

6-6 i would play 13/7*/1* with 1 piece and 13/7 with 2 other piece (i think)

grenv 
Temo: Re: 7th spot
Hrqls: I think the move you suggest is a huge blunder and would love to try a computer analysis at some point. Your opponent has a great chance of running or blocking your 7 point etc etc.

I'm sure with that particular roll you must hit the opponent on your 7 point. In fact even with 6-4 you should play 13/7 24/20 and with 6-5 I would hit both (13/7 6/1).

Interesting problem: If you roll 6-6 do you play 13/7*/1* or 13/7* 24/18 ?

grenv: if my opponent went 24/18, 13/10 with his 6+3

and i would roll a 6+2 after that, i think i would go 1/9 or 1/7,1/3 (i think the second because i like to advance my last piece at least a little bit, i somehow like the 3 spot)

30. Marto 2006, 20:05:03
grenv 
Temo: Re: 7th spot
Hrqls: I'm sure in the situation I described there is no better move than the 2 I siggested. I think 24/22 is slightly better than 13/11 unless you really need a gammon.

What would you play? Anyone else have a theory?

30. Marto 2006, 19:43:19
Hrqls 
Temo: Re: 7th spot
grenv: hehe thats exaqctly what has happened a few times the last weeks :)

if i would go 13/7* then i would go 13/11 as well ... if i were taking the risk then i would take it well and provide with enough options to secure the position

i still wont do it myself though .. i think the risk is too high .. although i might do it when i am in a weird mood (just as taking the 5 spot while leaving a single there :))

30. Marto 2006, 16:55:27
grenv 
Temo: Re: 7th spot
Hrqls: If you don't hit and they block the 7 spot it's very good for them. High risk high return.

For example if you started with a 6-3 and moved 24/18 13/10, then your opponent rolled 6-2, his best move is to hit you with 13/7* 24/22 or 13/7* 13/11

Temo: 7th spot
lately i see a lot of players hit my single piece on the 7th position (close to their home) leaving a single piece of their own there

they even do this at the start of the game

isnt this too dangerous ? as its quite easy to hit it back (7 with 2 dice, or a single die for a piece still in their home) and they will lose a lot more than i lost when i hit them back ?

or is their some secret reason for this ? :)

alanback: I would agree if the universe of players was larger, however with a limited number of players who have that level of experience it doesn't seem too odd to me.
Thankfully the list includes the number of games, so we can easily look at it any way we want.

Temo: Last rant
I'm going to say this one more time and then shut up. There is a basic flaw in the ratings system as applied to backgammon games. It simply should not be possible for a player to rise to the top of the ratings in fewer than 100 games. Yet the top 3 rated hypergammon players and 2 of the top 3 backgammon players have fewer than 100 games behind them. Any system that allows this is broken and needs to be fixed.

23. Marto 2006, 20:01:45
alanback 
grenv: If this were a game of backgammon, I would probably agree with you. But I think in Crowded it takes a bit longer to bear off fully after opening the 6 point, so I thought the chance of a gammon was negligible. It is always necessary to consider the risk that I could be forced to leave a shot during the bearoff, a risk I prefer to avoid!

grenv: *nod* but when he was bearing off i had a little chance ... not big enough to worry about though

but i wonder if that chance is lower than the chance of me winning 2 more matches (as the first is the crawford game)

so far alan won 6 out of 6 games against me, so him winning at least 1 game in the next 2 is about ... hmm 100% *fear* ;)

23. Marto 2006, 19:09:56
grenv 
Hrqls: You had almost no chance to hit back, all he needed was a 7 or 8 on 2 dice, or a 1 or a 3 to block you entirely.

23. Marto 2006, 17:52:20
Hrqls 
Hrqls: hmm on the other hand .. if i had accepted i would have had the option to double back making this the final game in the match

argh! doubling questions at the end of the match are tougher than at the start :)

23. Marto 2006, 17:50:32
Hrqls 
Hrqls: on the other hand though ... i still had a chance to hit alan back .. and by taking this 1 point we entered the crawford game in his advantage

so i think it was a nice thing to do double after all :)

23. Marto 2006, 17:42:49
Hrqls 
BIG BAD WOLF: hehe *nod* somehow i forgot the fact that i still have to come off from the bar first ... i was thinking 'can he send me back to the bar' and 'do i think i can hit his single piece there' :)

now i realize he could easily close it down i am glad i didnt ponder too long and declined quickly :)

grenv: do you really think he could have gammoned me ? how far away does someone have to be to have a chance to be gammoned ?
i would have 5 pieces out, 4 which i could move in with 2 moves, 1 piece which could take longer. i suppose i would be out when there are 2 positions free, leaving my opponent with at least 8 pieces, which means about 5 rolls .. hmm .. calculating out loud now ... 5 rolls .. thats about what i would need to get my pieces in my home and 1 out :)

i think i could have been gammoned indeed with just a little luck for my opponent, but not as much as i thought it would take :)

Seriously, it was a dead drop, I only cashed because I didn't see a serious gammon possibility.

Hrqls: I don't know any stats about a position like that or not, but in my opinion - I would not have taken the double either.

Your opponent could easly close up your only opening (even with a 7 - which as I understand the most common dice roll) - or at the very least, moved his piece so you could not land on him.

You would have needed luck, too much lunk in my opinion to accept it.

Temo: Re: no double?
Hrqls: You should have been able to offer a double - up until the time you hit "roll dice", which after that you would not be able to - but before that, you should have had the option.

15. Marto 2006, 17:16:23
Hrqls 
i am not sure if i want to double, i am just missing the option

is there a reason why i am not allowed to offer a double in this position ?

Temo: Re: a draw??
Marfitalu: I believe the question was "why is this a draw and not a win and a loss?".

I think this is a question of definition on this site. A match is considered a single game no matter how many games are involved, dubious but probably easier to implement?

Temo: a draw??
I just recently noticed while looking at my finished games, that I am showing 2 draws in anti-backgammon...
I have neither offered a draw or accepted a draw, so I looked a little further... the games in question were part of a stairs match that my opponent and I split( a win, and a lose)...so why does it count as a draw? because it is part of a 2 game match? ...seems a win and a lose would be sufficient for the record books(bkr ratings) ...I think a draw would only count in a game where there is no clear winner...

...pardon to the powers that be if they feel this should be posted on the stairs board :o) ...it was perplexing to decide where to ask a gammon-stairs question...

GnuBg also says that you made two very bad moves, two bad moves and two questionable moves while pgt made only two bad moves. Moreover, GnuBG evaluated the luck factor in the following way: pgt: None, Czech Chuckers: Go to Las Vegas immediately.

Temo: Re: Single-elimination tourney seeding
playBunny: I dont know the true rational, but in all of my sporting experience it is the most common bracketing that I have encountered. Generally in these situations though, the teams get their ranking by playing each other as part of a league or conference or the like.

For example NCAA college basketball tournament getting ready to start soon here, takes the top 64 ranked teams (basically) and pits #1 ranked vs #64 and so on down the line. Tennis is international and does similar in their tournaments. It seems to be quite common, and the ratioonaol seems to be that if you have earned the highest ranking to begin with you deserve to play in the finals against the number two ranked payer unles someone is able to upset someone along the way.

One point, in college basketball for example, your ranking is not in jepardy if you get upset as it is the last game of the season for you. In backgammon tournament here, your ranking is effected by an upset from a lower ranked player.

I think for a backgammon tournament here, set up likie this, it should be a 7 or 9 game match to make it more likely that the better player will not get upset.

Temo: Re: Single-elimination tourney seeding
pentejr: "In a tournament where one loss puts you out of it, those with higher ratings should be protected against one another in the early rounds."

I've never heard of (noticed) this bracketing method, let alone the rationale, so this in a new idea. You're saying it's about protection and the top half are the ones who are getting protected and the bottom half pay the price, as it were. #1 gets the most protection by playing #8, and the #4, being the least important of the protected, therefore gets the least protection by playing #5.

If that's the aim then it makes sense to me. Certainly it would work in my favour in tournaments, lolol.

"I think we have different definitions of "fair."

I wouldn't call it "fair" at all because it's deliberately designed to ease the passage of some at the expense of others. Nothing fair about that as I see it (showing lack of favoritism; in an evenhanded manner; free from favoritism or self-interest or bias). But if that's not a priority, that's, er, fair enough.
