you know, if i saw someone rising that fast i would go and see for myself, but not bringing it up on a board like this. ZEROZERO resigned all those games when i wasn't even online, then i came online and asked him to stop, oke it was fun to be number one, but i play so much hypers, that in a few days i will probably go down fast, and i really don't care about those ratings, i just love playing those games, and that's it, but i rather prefer that if anything like that happens again, just send me a message and ask me what is going, so i can explain, rather that, then now, hearing that you were talking about it, about the games and me, and i have to find out trough other people.
I'm not mad or anything, and i will keep playing everybody, but next time, just send me a message, please, or if you wanna say it here, just let me know, and not like this.
Thanks, peter, and hope to see you all in some games, you can play me, and try to get my rating down, lol
ZEROZERO: some players show weird patterns, have a look at some of the top players of hyper gammon .. i dont think there are any weird ones up there now .. but now and then a new player (often pawns) shows up in there with very weird games (often a lot of resigns by his opponents, which are also pawns, in games which the opponent would have won) ... some people look at the top ratings to have a look who are moving up the ranks and who arent .. and to study their games to see if they can learn anything new from them and to challenge them for an interesting game themselves
i know both you and nobody from several games and know you arent cheating (at least i wouldnt expect you two to do :)) ... but curiousity is a characterstic of humans which cant be denied ... even though it wasnt cheating i was curious to what happened myself as well :)
not thats its a matter of life or death to me .. but something which can make one curious (and that doesnt have to be a bad suspicion)
alanback: wow ...I didn't know that you people were "spying" on players moves and profiles and stats and whatever ....feels like " Big Brother" LOL..maybe Peter and I better put our wabcams on when we are playing so everybody can watch us doing strange things ROFLOL
playBunny: indeed I wouldn't know how we could cheat on whatever by resigning a few games (read : a lot of games) and winning a lot of games a few days later
Pbarb2: It's a pity that you were sickened, Barb, as I had certainly had no thoughts that there was cheating going on. If I discover cheating then I'm "happy" to shout it out.
Good Job, Luc.. I have played these two..Luc and Peter for a couple years at another site. I even talk to them on my IM together. I was very sickened when I read this. Not everyone is a cheat if that is what was being thought here.
Just wanted my 2 cents as well. Thank you.
BARB
playBunny:
LOL...didn't know we were that interesting ...:) But let me take away all your suspicions or curiosity or whatever.
nobody25 and me are very very good personal friends since years. We play a lot together on this site .Sometimes we play at our own computers at home and sometimes we play on the same (my) computer cause we are togheter a lot of time.
We always play lots of games against one another but we choose for 30 or 40 days a move cause sometimes we don't feel like playing or sometimes we can't play for a couple of days because of my work or because of other reasons . We play safe lol.
Now, what happened that day when I resigned a lot of games ? Very simple ....I was in a losing week and lost almost every single hyper game against my good friend . I was a bit bored with the hyper games that evening and I thought (at that moment) we had too many games of hyper running . So I started to delete game after game after game ...till suddenly nobody25 called me on the phone and yelled :" STOP !What are you doing ???? Stop deleting those games" And so I did ....we now take a few days of rest and play a game from time to time .
That's what happened . ANd don't be surprised when you see our numbers of games rising again next couple of days , cause I'm ill for 5 days and have to stay at home . Nobody25 is at home as well this week so we got plenty of time to play games again :)))))
You know ...we are on this site to play our games and not to investigate what other players are doing here ... ...But oh well...everybody has the right to do here what he(she) thinks is fun .
If anyone got anymore questions about interactions against nobody25 and myself, please don't hesitate to contact me ...Have fun
basplund: ok, but bug or not there should be the option to offer what amount of points you wish to resign by, when the resignation offer is sent, like in live tournament play, then it is up to the opponent to decide whether to accept or decline.
basplund: in my opinion you should have got 3 points for that game, i assumed thats what you would have got when i resigned, i'll resign a gammon game next to put it right.
Does anybody know how many points you would get in Anti-Backgammon with the double cube if the opponent resigns early in the game? Doesn't it count as gammon or backgammon as in the standard backgammon variant!?

I can assure you that if we play together 30 games and finish them today, there is no chance you or i will beat the other 100% of the times!
But as i see here this is not the case since they both play a huuuuuuge number of games at the same time so this is somewhat possible although i see maaaany resigns.....?!?!?
Notice how many games they have playing against each other! !!!!!!ENORMOUS!!!!! value......
And 40 days per move.
Pythagoras: No suspicion, just curiosity. It's a long-standing playing partnership and maybe there was a falling out that day, for instance. It just struck me as an interesting snippet in the Backgammon soap opera.

I guess you are refering to the matches resigned from ZEROZERO at 1 February 2006 and at 29 January 2006 and at 26 January 2006, always against NOBODY25.....
But there was some ZEROZERO's massive wins at January 26 againt NOBODY25! Covering traces?
What is your suspicion.....?
Fencer: Sorry, but this board is way more active and I thought I would get a quicker result in here. I have posted on a line board and had zero responses before :(
Pythagoras: Thank you for your reply. I'll keep in mind what you have said and see if Reinhard is up for another game with the SMIRF and me. Perhaps I'll check over my 30 odd games against the SMIRF and see what went right or wrong in them against it and see how it applies when comparing your anti-computer play. Perhaps I did some of that just using my usual plan of always trying to make the best move no matter what the goal is, long term or short term. Thinking horizon, eh? Yes, us humans can see the big picture and miss all the details. It's an idea. That SMIRF sure is strong in the tactical department. Alway leaving bait or blazin' in with something that looks bad and then you've lost the game.
What you say seems to hold for Backgammon, and that explains a big difference in the nature of the two types of games. Alas, I've stopped playing Backgammon until a couple of features are added, but I'll keep it in mind if and when the time comes. playBunny has lots of Backgammon ideas and knows some of these programs quite well. I think he argues with them too! :) Backgammon isn't as cut and dried as Chess is.
Walter Montego: I saw that you did this. I can't beat the SMIRF any more and yet I can hold my own against you. I'm confused.
You should not! What i do perfect is to play with anti-computer style! That obviously doesn't work well against humans....:-)
What I want to know is, what is this anti-computer play you talk of?
Well it is just one rule that you have to find the way to make it work over the board! Play moves that would result in a favourable position for you that goes beyond their horizon! Easy to say yeah? Difficult to make of course....
What does this mean? Well my main strategy is to play Pawn moves at the opening and create a kind of position that limits the movement of the computer, WHILE i place at clever places and always in the side of the opponents King the more heavy pieces. At the same time there should be a closed center all the time! Most of the time i try to weak my other side(the side i don't place the heavy pieces)
and the computer tries to take advantage of it weakening it's King position and losing many tempo's for gaining material. That means if the development goes normally, (the computer can't attack my King since i preserve a good Pawn structure as i've said and a closed center) i would have a hidden attack. Hidden from the computer's search. Horizon effect! The rule i gave. Then i advance the Pawns on the opponents King side and the result is always the same.....
The games with Smirf was my too first Embassy Chess games so i didn't managed to understand the way to do it. My brain hasn't worked the patterns for this game for obtaining an anti-comp strategy. But even this way, i've managed to create with white something similar to what i have said. And i would win easily if i would be a little more patient and didn't played a bad move(move 20). If i've waited 2 more moves then result would be much easier.
In my black game i didn't followed the afementioned procedure of anti-comp but of course followed the basic rule. I had prepared from move 3 only a Queen sacrifice for an Archbishop that Smirf didn't accepted! I was impressed by Smirf at that point!
If Smirf accepted it would be positionally lost although i would have given my Queen for the Archbishop. But game have more surpises for Smirf.
After some clever manoeuvres by me, we resulted in an endgame where i had an Archbishop against a Rook. Every human knows that this is better for the Archbishop side....But it was not easy. I have found a way to make it easy giving my Bishop with 35...Ke6!! So how can one play such move?
You play againt a computer. You give it material for free at a first glance. But you know that after Ad2+ Axb3 you would get 2 passed Pawns. Computer can't see this as it is many plies beyond its horizon! Our rule. So play it.....2 horses are too far away from the passed Pawns so....No computer can see that Bishop sacrifice.....!
So my anti-comp system is to play Pawn moves at the start blocking the position and keeping a closed center, bring heavy pieces in the side of the opponents King and wait, wait, keep your King safe, give the computer the chance to prevail in the other side of the board and then start the attack with Pawn pushes. As long as the center is closed with no fear to open and you have 3-4 pieces attacking at the King by means of be in the same side with him, the success is guaranteed.....
Closed center is easy for me to achieve at Gothic Chess but i find it more difficult to achieve at Embassy Chess maybe because i didn't managed yet to understand he game....Closed center means that whatever Pawn move the opponent makes (D,E,F,G Pawns the others are not any disturbing for us)
the center can't open.....
Does it work against human players?
Of course not! It might work against weak players but against strong it doesn't....Actually it worked against Caissus and Mely and Matarilevich when i played as Chessmaster1000 Gothic Chess and i was surprised by that.....!
How come the computer programmers don't keep such plans in mind while designing their programs?
It's not that easy to make a workaround to prevent anti-comp play, as it may seem..... Reinhard(author of Smirf) after i offered him 2 new Embassy Chess matches after i won 2-0 Smirf, told that he must modify Smirf before he can play against me again. And that this would take much time before it happens if it happens at all. This is sad for 2 reasons. Of course because i think Smirf has the potential to become a very good program, even more than it is now, and second because i just wanted to play 2 more games while now i have to wait so long.....Greg Strong(author of ChessV) after i defeated his ChessV 2-0, was very interesting on how i'm doing this and i've given him my way of thinking. He said that he would try to create a new ocncept of thinking at ChessV to think more like me....I haven't had any news from then....Ed Trice(author of Gothic Vortex) often mentioned that he has added many improvements to its King safety from Vortex games against me.
BUT still i have the impression that i will be able to beat all these programs for the next 2-3 years....
Does this work against the Backgammon programs?
No! In a game where luck comes to play too, this can't work! And also remember: While at Chess-type games humans are better in the positional area while comps at the tactical area, at Backgammon the exact opposite happens! So you can't outplay them at positional decisions.....Only on some technical decisions....
These neuronets you speak of for Backgammon, why aren't they used for Chess type games?
They have been used in some projects but they have completely failed to give a strong Chess engine!
And what about Dark Chess?
What about it? Neural nets can't be used there also as there are many difficulties on that. Even if someone succeed the result would not be good.....
Dark Chess has to be programmed by the usual computer Chess type algorithms. Alpha-beta/transpositions/iterative deepening, etc... Well that's how i plan to do it....But only after i program a Chess program first. So i'm afraid that you have to wait a bit more....:-)
Pythagoras: I saw that you did this. I can't beat the SMIRF any more and yet I can hold my own against you. I'm confused. THough recently I had chance to win a game of Janus Chess against SMIRF. Perhaps my play has gotten better recently, but I can't say.
What I want to know is, what is this anti-computer play you talk of? IS it something that I could easily adopt and use? Does it work against human players? How come the computer programmers don't keep such plans in mind while designing their programs? Does this work against the Backgammon programs? Somehow I think not. These neuronets you speak of for Backgammon, why aren't they used for Chess type games? And what about Dark Chess?

Yes i haven't seen this Domino variant i was refering from the other known Domino Backgammon, but from somewhere else....I don't like the Domino as described at bkgm.com as it has some rules of "not move your back men until move 4, etc".
There can be of course many different variations and the proposed by me variant is just one that i remembered. I haven't really played this variant for the last 5-6 years so i don't remember if there was a better one Domino-variant....
As for the computer programs part, i see that many of you don't have a real idea of what computers can do and highly overestimate the abilities of them....
In the Chess game, human programmers needed around 70 years from the time they started their real and serious occupation with computer Chess, after Adriaan de Groot's and Claude Shannon's publications on computer Chess algorithms. Only recently (probably the win of Deeper Blue against Kasparov is the most known) computers started to show signs of equality or even superiority over humans at Chess. Before 3-4 years i could beat occasionaly and very seldom of course a top Chess program with some anti-comp play. Now i can't!
All this knowledge of course all this years, that came from Chess programming is used to produce for example Gothic Chess programs or Atni-Chess programs or Reversi, Checkers programs etc. Today no one can beat a Reversi 8x8 program indeed. They are invincible! They might solve the game in the next 7-8 years or sooner.
Checker programs have for a long time prevailed over humans in the game. After Marion Tinsleys' death computers have completely dominated at Checkers. The freeware and top Cake Manchester for example if inserted in a tournament with humans will dominate easily!
Gothic Chess type programs or to say CRC type programs, have yet a long way to travel before they can be like their Chess relatives....In this site i have beaten such a program at Embassy Chess with a humiliating way. I gave my Bishop and while the program thought it will clearly win i knew that its loss was obvious! That shows that at CRC type games humans can still beat computers. I have yet to lose from November from a computer at CRC type games. ChessV, Smirf, Vortex, Zillions are all losing. So CRC is still at humans hands!
Anti-Chess: Here computers again prevail but this is logical since this game has some long forced variations that computers with proof-number-search can find in a second while us have to be tortured to find....
Three Checks Chess, Atomic Chess, etc: I don't know another computer player for this game except Zillions and ChessV and are both very weak at it, so human is still above them....
Backgammon: Probably one of the first tries for a Backgammon program was made by Hans Berliner at 1979 with a program called BKG(and a version number i don't remember). Due to the brilliant mind of Berliner one would not expect anything else except BKG to be a good program even in 1979. And BKG in an exhibition match against the world champion of that time L.Villa, won the human with a 7-1 and a won a symbolic 4000$ prize.....Although BKG played well the mistakes that made were more than the mistake of Villa and it was obvious that it was far away from an expert level. It was until G.Tesauro created a neural net Backgammon program. A method that all todays top Backgammon programs (GNUBG,Jellyfish,Snowie,BGBlitz) use.... He first tried an approach in which the net used some Backgammon knowledge and the program was trained on games of expert players and with this way the program derived its weights....That was called NeuroGammon and was good eanough to win the computer Olympiad, but not good enough to become an expert. It was G.Tesauro's TD-Gammon that changed all. TD-Gammon used a neural network that was trained using temporal-difference learning. That means the program (networks) without having almost any knowledge at all played against itself some thousands of games became very strong. The networks using as starting weights the Neurogammon's and playing again thousants of games became the most strong bot ever at Backgammon until that time. Final TD-Gammon 2.0(or 2.1 i don't remember) used 1500000 games of training against itself and reached level of expert!
Todays programs are on the strength of top human players or even stronger....
Domino Backgammon. As Playbunny has said the branching factor is very big and the number of 36 dominoes or even 21 is big enough that no program could play it perfectly for the next AT LEAST 18-19 years! Consider this: 21 dominoes with for each domino to have around 3-5 possible plays. That means a branching factor of around 84 for the first move! Second move would have ~20·4=80 That means to be able a program to solve it should calculate (84·80·....·4)^2 which is a very big number.....!
Not even dedicated neural net with super computers could do it in less than 15 years and that may even be a huge underestimation.....
Walter: Good questions. I think some jolly discussion could be had about how the dice distribution should work. :-)
Backgammon Galore assumes a literal domino set and assigns the 21 dominos in a fixed pattern. Each player plays only their own dominos. When the dominos are exhausted the players swap sets to ensure fairness.
Pythagoras envisages 36 dominos to correspond with the 36 dice rolls and each player picks one from what's left in the set. Whether that's one set per player or a single set between them isn't perfectly clear, though I think he's saying one set each.
This program that I've just played gives each player twelve completely random dominoes. Eg, the computer's selection for the current game includes two 4-4s and four 6-3s, while my set has two 6-3s of its own.
With the 36 domino set per player, one round of dominos would be sufficient for quite a few matches and I imagine that games between good and experienced players would become quite predictable. The program's small random set of dominos makes for more variety of games.
Nightstorm: And then the prediction loses pace again... I downloaded that program and played a match. I didn't even have to look at the computer's dominos in order to thrash it. Nor did I particularly plan my own domino usage much. Someone using it to make their moves may go to the top of the rankings, like so many players do with their first few matches, but they'll have a hard job staying there.
grenv: But dominos only come with one 1-2. With dice you can roll it two different ways. If this variant has both 1-2 combinations calling it Domino Backgammon is not a good name for it. It should just have the dominos possible or give it a different name. Have you played this version before?
playBunny: I count 21 combinations of dominos, not 36 if you're just going to use 1-1 through 6-6 and not the blanks or higher dominos. 1-1 1-2 1-3 1-4 1-5 1-6 2-2 2-3 2-4 2-5 2-6 3-3 3-4 3-5 3-6 4-4 4-5 4-6 5-5 5-6 6-6. Or does your version have two of each domino that isn't a double? That'd add 15 more to it to make 36. With the blanks there's 28, still not 36. And how would you move a blank? Perhaps 1-1 to 8-8? That makes 36.
About the set of dominos that the players draw from. Is there one set that the players draw from, or does each player get his own set to draw from?
Nightstorm: LOL. Well I never! So the prediction gets more likely. Now we just need someone who would buy and use the program in order it to become "champion". Perhaps R**too would be interested.
alanback: I predict that someone here would have a computer program that would play perfectly every time, would shoot to the top of the ratings and stay there.
I'd think there are a few wee problems with that prediction. The first is that there probably is no such program. Domino-backgammon is rather an obscure variant and so someone would have to be a real enthusiast to write such a program. The individual moves could be done using the GnuBg engine, of course, but there would still a fair bit of programming to handle the mechanics of the game and the interface, etc. That's within the capabilities of a decent programmer. However, playing perfectly would mean choosing the correct sequence of dominos for both the player and the opponent. Given that the branching factor is so high, finding the solution would be best served by having dedicated neural net, which is highly specialised programming. Then that program would have to be in the possesion of someone playing here. And finally that person would have to be comfortable with using a computer to make their moves.
Hrqls, not always in crazy narde, a blot cannot be hit so the more ground space they cover the better. I could have all 15 bits in a line and you wouldnt be able to use some of your doubles. The doubles you cant use i would get! Plus when the pieces get to the bear off section in this varients they are stuck and you have to get the exact number to bear them off.
Grasshoper is very interesting game too and there is no luck at all inside it! It's a little complicated at the beginning but as you play it you will appreciate it more.... I used to play this game in the past but now i have almost forget it....:-(
It would be nice to add 4-5 more Backgammon variants. Actually i hope for 8-9 but from 0 i can choose 4-5
