题目: Re: Why the difference?

Undertaker.: I think that this has been asked before, yet i am at a loss to think of the answer. I am sure it was something along the lines in that the player might wish to use that set-up again....... which don't make sense as that could apply to any of the games in the Game Editor (Screen Chess, Crazy Screen Chess, Battleboats, Battleboats Plus, Dark Battleboats, Espionage, Small Espionage, Fast Espionage, Open Fast Espionage, Small Fast Espionage or Logik)

题目: Why the difference?

When someone finish to play a espionage game or a logik game, all the pieces of both players are showed. However, in battleboats games, the loser cannot see all opponent boats.

Why this different criterion?

In some forums you have a timed edit feature. You get a limited about of time to edit a post and after that the edit feature is gone.

Is it possible to implement that feature in the fellowships? It would be nice to have it so that for the poster, the edit feature is timed but for moderators and BB there is no time restrictions. :)

题目: Grunwald Chess

from Wikipedia:

The Battle of Grunwald (or 1st Battle of Tannenberg) took place on July 15, 1410 with king Jogaila (Władysław II Jagiełło) leading the Kingdom of Poland and the Grand Duchy of Lithuania in alliance against the knights of the Teutonic Order who were led by the Grand Master Ulrich von Jungingen. The engagement in the Polish-Lithuanian-Teutonic War (1409-1411) was one of the most important battles in Medieval Europe, and the largest battle to involve

KNIGHTS

The forces of the Monastic State of the Teutonic Knights were decisively defeated in the battle, but were able to defend their castles and retain most of their territories despite the long-term consequences they suffered as a result of losing the battle. The order never recovered its former power, and the financial burden of the ensuing reparations eventually caused a rebellion of cities and landed gentry.

I decided to commemorate this big event (600 years anniversary) by creating a new chess variant called Grunwald Chess ...
The rules are exactly the same as in traditional chess, with the exceptions given below:

1. Knight can move also as pawn (including double move from starting position)
2. Knight can promote as in traditional chess only when they reach 8th or 1st row as a pawn ...
3. En passant is possible as long as knight moves two fields from its starting position as a pawn ...
4. Knight is entitled to move two fields as pawn as many times as it wishes after reaching the 2nd and 7th row on its sites ...
Below is the link to my new blog about chess variants. Please visit me and "tell me what is wrong with me, lol"

题目: another frog game...

I really want a new frog legs game...I'm very frustrated in playing the current one. I will NEVER lose unless people play risky. you can use risky logic and win in this game.. very weak! I would like to see higher risk for a guess that is not proven with logic...( if they guessed). also more frogs (20) on a board at one time will eliminate risky guessing. an example if i see threee 1s in a row i know logically that the frog is inbetween them. but this is not true in all siutations so if they guess and are correct they would only get 1/2 points and if they miss they would loss 10 pts. b/c it was an unfounded guess! Do not reward GUESSES.. and punish them severly.

题目: Re: Restrict the number of tournaments created, by each player, per month

pedestrian: Yes, i think your suggestion is a good help for this problem. In this moment, there're not much search options and if we're trying to select a specific game type to play a tournament, we find many tournaments, because most of them include all games.

Why not someting like that: select a specific game type and then appear the information (about this specific game type only) with the number minimum of players request to start that tournament.

Example: I select "anti chess" game and we have:
Tournament A - 2/5 (there're 2 players and we need 5 to start)
Tournament B - 4/8 (there're 4 players and we need 8 to start)
Tournament C - 14/16 (there're 14 players and we need 16 to start)

题目: Re: Restrict the number of tournaments created, by each player, per month

Undertaker.: I think the best solution is to implement better search options, rather than restricting the tournament creators. For example, a search for a specific game type should give you a list of only the relevant sections of each tournament (rather than the current list of tournaments, where you have to click each one and look for your preferred game). That way, you could compare your options more easily. Add to this an option to search for those tournament sections that only need a few players, and I think the problem is more or less solved.

The real problem is not all the empty tournament sections, the real problem is that we can't get rid of them in the search.

被Undertaker.修改(20. 二月 2010, 15:53:49)

Hi everybody!

There're some people creating many tournaments with same characteristics (all games and same time control) and it's confused for people choose a tournament to play a specific type of game, because some players want play the same type of game, but tournaments don't start, because players are dispersed for some tournaments.

I understand people have a good intention when are creating tournaments, but the result isn't the best and unfortunatelly these persons don't still understand it.

So, would be possible restrict the number of tournaments created, by each player, per month?

题目: Re: Top players' games

Beren the 32nd:

Well, here is one way. (Maybe someone has a quicker/easier way

)

There is a URL you can use to see the game history between any 2 people.

http://brainking.com/en/Profile?u=XXXX&op=XXXX&p=1 (change the X's to their user numbers)

You can find someone's user number by going to their profile. (ID #)

One way to find the top chess players, would be to choose "Ratings" in the left hand menu, and then click on "Chess"

Choose the people you are interested in, get their ID#'s and insert them in the URL above.

Of course, you may have to click on the different years to find some games. On that screen you will see a list of all game types they have played together. When you click on the game type. You will see the games they played this year. If they haven't, you will have to click on the other years. Unfortunately, the "Last 10 Finished Games" isn't working still.

题目: Re: Doubling cube in chess

AbigailII:
you cannot see it's beneficial for the trailing player that draws won't count?

I think that's a valid point - that's actually how it works without the doubling cube, too. In my defence, I'll say that I covered this possibility when I said that I didn't see any serious drawbacks. Let's take your argument a step further:

If I'm trailing in a match, and the current game is likely to be a draw, there shouldn't be any hesitation to double if that means the game effectively won't count, should there?

Why is that a problem? Most likely, the game is going to end in a draw. In that case, both you and your opponent gets the double of 0, which is 0. So you can double, but it will only have consequences if there are indeed other possible outcomes than a draw. Which I guess was sort of the intention of introducing the doubling cube in the first place. Or, in other words: If there is even the slightest possibilty that you might lose, there should also be a slight hesitation to double. And if there's really no such possibility, then as you say, there shouldn't be any hesitation. I think that is how it should be. I don't see a problem.

12. 二月 2010, 20:02:12

题目: Re: Doubling cube in chess

Herlock Sholmes: because I discovered a brilliant idea I WILL DOUBLE

Right. So, if that's the only reason you double, it means "if you double, you think you've discovered a brilliant idea". Or are there other reasons that you will double? Reasons that occur often enough for your opponent not to consider "double by Herlock Sholmes means he thinks he has discovered a brilliant idea".

题目: Re: Doubling cube in chess

pedestrian: The leading player can double the effect of a draw, thereby bringing himself closer to winning the match. This can be remedied by not scoring draws at all, and I really can't see any serious drawbacks of this solution.

Wait, you do see that the leading player can double the effect of a draw bringing himself closer to winning the match if there's a double, but you cannot see it's beneficial for the trailing player that draws won't count? If I'm trailing in a match, and the current game is likely to be a draw, there shouldn't be any hesitation to double if that means the game effectively won't count, should there?

Of course, you could do something wild like "In the case of a draw, the person holding the cube scores half the count on the cube, the other player gets 0. If no player holds the cube (no doubling has happened) the score is 0.5-0.5". Which means that a score of "1-0" could mean either win by white, or a draw with white having doubled. Non-sensical if you ask me.

题目: Re: Doubling cube in chess

AbigailII:
Draws are a fundamental part of the game of chess, and very common. Scoring a draw as a loss is a big change of the game. You might as well replace the rooks with diamond aces. It just doesn't make sense.

Giving both players 0 points in case of a draw doesn't equal "scoring a draw as a loss", and if the game is played as part as a match, it doesn't change the game at all. It simply means that draws aren't counted, and the match continues as if this game wasn't played. World championship matches have been played this way (but not with the doubling cube, obviously!).

As you pointed out yourself, when draws are scored as 0.5 there's an undesired side effect of the doubling cube: The leading player can double the effect of a draw, thereby bringing himself closer to winning the match. This can be remedied by not scoring draws at all, and I really can't see any serious drawbacks of this solution.

Btw., how do diamond aces move on a chessboard?

题目: Re: Doubling cube in chess

AbigailII: few positions ? many, many position in chess have undiscovered yet better plays ... not just few ... my strategy is opposite to what you think: because I discovered a brilliant idea I WILL DOUBLE, not the other way around. You may created an open tournament for every skill level but you may also restrict weak players, right ? So where is the problem ... Bill Robertie one said (two times backgammon world champion) that an average, very good player would have zero chance with the elite players in the match to 21 points ... these players also can double after the first roll knowing that they will win in the long run ...

Would they do it ?

12. 二月 2010, 18:47:51

题目: Re: Doubling cube in chess

Herlock Sholmes: Just because you can think of a few positions where you would like to use a doubling cube doesn't imply it makes sense to have a doubling cube. Having a doubling cube means the cube can be used at any time, not just in the positions of Alekhine games.

If it would be my doubling game scenerio I would offer doubling cube to my opponent after discovering a brilliant combination and he would most likely accept it ... is it so hard to imagine that I would double my score ?

Ah, so, your strategy is "if I double, I've discovered a brilliant move". That would only make your opponent look harder. He's then more likely to find the combination as well, and either refuses the double if he believes the combination to be winning, or taking it if he thinks he can refute the combination.

And those who played with him were top players, not brainking masters ... and he wouldn't offer doubling cube after the first move since he also was beaten by others. So, your argument about automaticaly doubling after the first move has no place here ...

Ah, and since BK is populated by Alekhines and players who have beaten him, your arguments do hold?

You may call me an engineer, but I try to see what the effect is of introducing a new rule. And the situation is that BK isn't a closed tournament whose organizing committee invited a group of closed matched players. Player strength varies on BK. There are many games between players of different strength. In tournaments, you don't get to pick your opponent.

I was studying Alekhine games and believe me, had no idea what this genius was doing until the last two or three killing moves ...

题目: Re: Doubling cube in chess

Herlock Sholmes: there are two guys who want to play chess for some stake, and agree that they can raise the stake during the game and if the opponent refuses to accept, game ends and the money belongs to the one who offered the doubling ... could you tell me what is wrong with this scenario

For one, this has no analogy with BK. In BK, you win, draw or lose. There are no other outcomes. There's no "winning by a larger amount". If you play a 10 point match, you get the same reward regardless whether you win 10-9 or 10-0.

Second, that would mean the stronger player would offer to double the stakes at the first move, while the position is still equal, instead of waiting till he has an advantage, in order to maximize his chance of playing for doubled stakes.

Off the top of my head, I'd say the draw problem could perhaps be solved by counting draws as 0 points instead of 0.5. Wouldn't that cancel all speculations about doubling in a drawn position?

Draws are a fundamental part of the game of chess, and very common. Scoring a draw as a loss is a big change of the game. You might as well replace the rooks with diamond aces. It just doesn't make sense.

题目: Re: Doubling cube in chess

Herlock Sholmes: Unfortunately, I can't think of a chess equivalent for the kind of cube handling decision one often must make in backgammon: is my position too good to double? (i.e., should I simply play on without doubling, because I have sufficient gammon chances?)

This is not to say that I don't like the idea of using the doubling cube in other contests...I DO like it, even if I can't always clearly state optimal rules or scoring implications.

Once, while at the curling club, I was a spectator watching games through the glass as a friend began playing. His team suddenly found itself in a difficult, dangerous position. I knocked on the glass, smiled, and held up a doubling cube with the "2" facing him. (I ordinarily keep my backgammon set at the club; my friend and I both play backgammon as well as curl.)

He completely understood my mocking cube gesture. He smiled back, and "gave me the finger"...in a friendly sort of way.

题目: Re: Doubling cube in chess

AbigailII: Interesting discussion. In your situation, I would actually do the opposite. Consider the two extremes:

If both you and your opponent keep redoubling, the entire match will be decided in just one game. That means that you're just one mistake away from losing the match. More specifically, you would lose 26% of the time in this case (not considering draws).

In the other extreme case, if nobody doubles and each game is only for one point, your chances of winning a long match are significantly higher. I'm not going to do the math, but the more games you play, the smaller the chance is that your opponent will win more games than you. Your risk of losing the match will be significantly lower than those 26%.

In general, I would say that the stronger player should be conservative in using the cube, while the weaker player should be eager to use it. I even have a feeling that this is true in backgammon as well, but I wonder what stronger bg players would think about this?

11. 二月 2010, 20:56:08

题目: Re: Doubling cube in chess

joshi tm: I think when you are the doubling player the opponent could always redouble when he thinks he is winning, so if you double there allways will be 4 point at stake when you double on turn 1.

I doubled because my rating is 1746 while Herlock Sholmes rating is 1560. If those ratings are our true strengths, the expected score is 0.74 - 0.26. Who wouldn't double in backgammon if the their equity was 0.74?

Of course, ratings only approximate true strength, but given enough games, it's a fair estimate.

And if my opponent waits to redouble when the position gives him a winning advantage - I would resign, losing 2 points, not 4.

But I could tell you what my opening move would be: "Double". So, basically, all scores are doubled. Instead of "1-0", "0.5-0.5", or "0-1", the scores will be "2-0", "1-1", "0-2". Frankly, that doesn't do a whole lot for me.

题目: Re: Doubling cube in chess

Herlock Sholmes: as far as I understand, two kings and two bishops is automatic draw, and ofering doubling cube is a nonsens.

First of all, there's no such thing as an "automatic draw" in Chess. There are some blitz rules that state that if your opponent runs out of time, you cannot claim a win if you don't have the material to mate, regardless how bad your opponent plays; there are also some rules stating in which situations one of the players may claim a draw - but those are not enforced in BrainKing. Second, I'm not a fool. I picked a situation that's theoretically a draw, but does allow a mate: White: Kc1, Bc3; Black: Ka1, Ba2. Black is in check, a2 is occupied by his own Bishop, b1 and b2 are covered by the white King. Third, how is the "nonsense" part to be coded? A game starts with a doubling cube. At what moment in the game does offering a double lead to BrainKing replying "heh, dude, we're playing with a doubling cube, but obviously, doubling is nonsense, so I'm not going to let you"?
