Onderwerp: Re: rating systems and the BKR
Actually, I'd be in favour of introducing a "falling rating" system, not necessarily instead of the existing system but maybe as an addition to it. It would work like this. Existing BKR would calculated just like now from the outcome of games. However, additionally an amount would be DEDUCTED regularly from ALL BKRs. This could be a percentage like 0.3% per week.

This would mean that you have to keep playing and keep winning in order to keep a high rating. If you don't keep playing then people pass you and your 2700 rating will fall to 2300 over the course of year and down to 2000 over two years.

This is like negative interest in a bank account! The interest rate could be adjusted of course - 0.3%/week is only a suggestion - and the time it's applied could be daily instead (by a smaller amount). But the principle is still there that you couldn't rest on your laurels once you got to the top.

What does everyone think?

Stormerne 
Onderwerp: Re: rating systems and the BKR
jfa: The reason I prefer the falling rating system over the removal system is that there are many players who, like me, like to concentrate on just one or two games at a time. So I might spend a year on chess and tablut and then another on another combination of games like tablut and backgammon (or more likely Go or Xiangqi if they ever appear). That's the way I play because that's how my mind works. I prefer obsession to diversity! :) I wouldn't want my ratings removed just because I'm having a sabbatical on one game to concentrate on another, but I'd be willing to take the hit from a falling rating.

Onderwerp: Re: rating systems and the BKR
My preference is for the falling system, rather than removal. Although more complicated, it could be expedential ... 0% for the first month, 1/2% for next month, then 1% for third, and so on. The other question is what you would need to do to start on the slippery slid ... just make a move? start a game? finish a game? hmmm

jfa: With regard to not knowing potentially how good someone is, well there is the graph which gives you an idea of how high a person may have risen at one stage, so long as you are a paying member. Even pawns have graphs, just they can't see them.

Onderwerp: Re: rating systems and the BKR
WhisperzQ: What I was proposing is already an exponential system since the amount varies according to your level. Actually increasing the slope over time I hadn't planned for and I'm not convinced it would work, But there's an alternative: have a fixed drop per month. That means that the percentage increases over time. Perhaps 2 BKR per day?

It would start only when you have a rating, i.e. have completed at least one game in game type. You could also bottom it out at 1300 and not subtract points below that since that is the hidden starting BKR.

There is one problem with the "falling" system, and that is regarding multiple win matches. A 10 wins match counts as 1 game, and it could take a very, very long time to complete. If this is the only thing you have going, you could still be active and lose points.

In my own case, a good % of my tournament games end up in 3-wins matches. So many games are not even applied to my rating. I have 15 won tournaments, and most were 3-0 situations, so I have up to 30 games unaccounted for that look like inactivity. That is about 11% of all of my games dropping through the cracks.

What should happen is, after X days of no results for a particular game type, you just don't show on the "active" list. You are still there, no diminished rating, just not visible until you play again.

That way:

1. "Rating mongers" who just win a few games to get an inflated rating fall off the list.

2. Those who disappear due to a temporary leave of absence can re-appear when they start playing.

3. Those coddled into playing who are truly over-rated will rebalance the system by losing points once they become active again.

ChessCarpenter has drawn Game 1 in the World Open this evening in Philadelphia. He was up a pawn as Black in the Sicilian, but his opponent forced a repetition draw in less than 20 moves, a true rarity for that opening.

Onderwerp: Re: a good refutation . . .
ColonelCrockett: If you play Classical and/or Dragon variations then 2...Nc6 is good when white may avoid 3.g3, 3.f4, etc. and play an open Sicilian with 3.Nf3 followed by 4.d4 etc. Najdorf players often play 2...d6 for this reason. I consider 2...Nc6 as maybe best, but not a "refutation".

ColonelCrockett: In my opinion, it depends on who you're playing. I'm a firm believer in playing the man not the board and over the board in matches (rather than here) that can be very effective.

I like to play 2...a6. That's partly because I used to play the 2...a6 O'Kelly variation in reply to 2.Nf3 throughout the 70s and 80s, even against people like James Plaskett, transposing into a Kan if white played c4. An early a6 is often effect as it often gets White out of his normal thinking. That can be good against bookish players or players stronger than you. Against a weaker player you might keep to more classical lines. Whatever you do, don't end up playing against yourself - always a danger with very tactical lines against a weak player when a simpler alternative would have done.

I'm pleased to see that 2...a6 still gets good stats here:
>http://www.chessgames.com/perl/explorer?node=33281&move=2.5&moves=e4.c5.Nc3&nodes=21720.32033.33281

though the sample is rather small. In any case it is NOT a refutation of 2.Nc3. I doubt there is one.

Stormerne: The reason I asked was to see how many players would try the move e6. This is inferior in my view because I want to play Bc4 and d3 anyway. I too believe in the "play the man" philosophy. I have won many games by not necessarily playing my best chess but by using psychological factors.

ColonelCrockett: I have a serious question now, why do you play the Sicilian with Bc4 and d3. I never understood this much. I see it often online and have never lost to it. I supposed most players who choose 1.e4 are attacking style and should be looking forward to Sicilians in which they can maintain more of an advantage and have a more direct plan attack.

11. juli 2005, 18:31:56
ColonelCrockett 
Onderwerp: Re: a good refutation . . .
jfa: do you think 2.Nf3 is any more "attacking" than Nc3? There is no direct threat early in the game with either move. I just don't like playing Nf3 because it gives Bg4 strength. Whereas Nc3 allows for a possible queenside castle with a pawnstorm if black castle kingside. isn't that a plan of attack?

Onderwerp: Re: a good refutation . . .
ColonelCrockett: sorry for not making myself more clear. I see absolutely nothing wrong with 2.Nc3, or Bc4 followed by d3 for that matter. I was just wondering what the attraction to this set-up might be as I have never played the White side. As Black it seems to allow me a rather free development. Thanks for explaining some of the thinking behind it.

11. juli 2005, 18:51:49
ColonelCrockett 
Onderwerp: Re: a good refutation . . .
jfa: you have a point here, it does allow for "free" development. but the freedom I think is mutual. The main point of the variation is that standard maneuvers for advantage by black just don't work. (i.e. e6-d5 is prevented, at least early, and the a6-b5 plan doesn't yield much, even against a queenside castle). It is also good since most Sicilian-ers are looking for the early d4 for white to avoid this line completely, I have never had any luck with d4 anyway. I'm certainly not saying that Nc3 is superior to Nf3 or that the d4 plan is bad, I'm just looking for the weak spots in Nc3 (as it is hard to find written materials on it, not like the ultra-popular Nf3).

Onderwerp: Re: a good refutation . . .
ColonelCrockett: I think I can say with confidence that there is absolutely nothing wrong with 2.Nc3 and if you ever want to try it with 3.g3 you should be able to find some good books. Spassky was a specialist in the Closed Sicilian and collected many scalps! The Grand-Prix Attack following 3.f4 is also well covered. As for the system with Bc4 and d3, you're right, I haven't seen much on it. Probably because, while somewhat popular at the club level, it is practically never seen in grandmaster games.

1. e4 c5 2. Nc3 gives Black several ways to get a comfortable game. As white in the Sicilian, you want to drive the play as often as you can, not limit yourself by giving the opponent a "trampoline bounce" in the early middlegame.

After 1. e4 c5 as white, I would smile and let the game proceed 2. Nf3 d6 (the most usual reply) at which time 3. d4 is expected. I just reply 3. d3 and watch my opponents' expressions change from happiness over heading into a well-known Sicilian system to one of mild concern, as white now has even more options at his disposal.

You can get into a very nice King's Indian Attack formation using 3. d3, and that opening is one that is "fluent" and very easy to understand, even better, it almost plays by itself, and white's attacks unfold almost without effort.

And the draw was against a program that finished last and scored only 1.5 points......

Also to correct ChessCarpenter that said "This site is very informative about ZAPPA and included on the site is a FREE download of the program which I think everyone here might be interested in!!",
i have to say that the version of Zappa that is available for free download is 1.1 while the one that played at WCCC-2005 was the 2.0 and it will become commercial.......Acccording to its author Zappa 1.1 is much weaker than top commercials while 2.0 is almost like them.....

Also in such a short tournament the result of Zappa maybe lucky and if instead 110 games were played, it may had much worse results.....We will see sometime at September when it will become available to buy.......

4. Lasker vs. Kasparov = 0-1
5. Karpov vs. Alekhine = 1-0

But the best matches would be the amazing Capablanca versus Kasparov of Fischer. My belief is that Capablanca was the best Chess-brain ever and he could not lose if he wanted.......Kasparov is incredible of cource but this is caused on a big degree due to his amazing preparation......
Fischer is just the top of brilliance but he was not so "normal" to become the best of the best, as he didn't last long enough......
