Places to Play Chess online, part 7 - Chesscube update

ChessCube Update: A message from the CEO | ChessCube Blog On June 21st, 2011 Chesscube changed their free to play model and now they charge you 15 cubits to play even unrated games. You have to "bet" an amount of cubits to be able to play. I can see this being a negative for people looking for free places to play chess. You can get 5000 cubits for $5 - which do expire slowly if you don't use them or you could use the small amount of free cubits they give you for logging in. Personally I dislike the change - they could have found another way to monetize. Related Posts

Studying Chess on Ubuntu Linux - Part 1 Setup

The first thing that you need to do is to setup your programs that are needed for studying. Generally players use a chess engine and a chess database program. Luckily for us someone created SCID an open source database program that works fairly well and is available on all platforms. I use Ubuntu Linux so my guide will be specific for Ubuntu but it should be easy to set this up on any system, including OS X, Windows and Linux.

Another benefit that Chess Players have received from open source is the chess engine Stockfish.
Stockfish is an open-source UCI chess engine based on Glaurung. Stockfish is an alpha-beta searcher and uses a bitboard representation.
Install SCID
  1. sudo apt-get install build-essential - This installs a Linux C++ compiler so that SCID can be built.
  2. sudo apt-get install tcl8.5-dev tk8.5-dev - This installs a runtime in Linux which enables the UI for SCID.
  3. Download SCID and extract to a temp directory.
  4. ./configure
  5. ./make
  6. ./make install

Install Stockfish
  1. Download Stockfish
  2. Download Stockfish Opening Book
  3. Extract Stockfish and run make profile-build ARCH=x86-32 for 32 bit Linux systems. 64 bit Linux systems can use make profile-build ARCH=x86-64
  4. Installation of this is a bit different than SCID.  I copied my executable (the file named stockfish) to ~/bin so I can have a place to save my opening book.
  5. Extract opening book to ~/bin.
Setup Stockfish in SCID
  1. Click on Tools and then Analysis Engine...in the menu
  2. Create a new chess engine by clicking on the New... button.
  3. Type in Stockfish in the name
  4. The command field should contain the executable for Stockfish.  Mine was ~/bin/stockfish
  5. Directory should be set to . to indicate that the directory to use should be the same as the directory that the executable is located in.
  6. Click on Configure UCI Engine.
  7. There are lots of options here - I mainly only change the book file to book.bin and set the Multiple variations to 4.
I will discuss how to use these programs next time I post about studying chess on Linux.

Attacking Chess Puzzle of the Week - 2011-03-17

It has been a while since I posted a puzzle of the week.  I will provide the diagram and a FEN string this week and then provide the answer next week.  Feel free to discuss the problem and talk through it with everyone.  The next week I will provide the answer to the puzzle and then another puzzle to solve.


Studying chess tactics and puzzles is a very important step in learning chess and it will help all levels of players increase their skills and abilities.

Chess News of the Week - French Cheating in Chess

Cheating in chess has become a very real problem. Online it has been around for years. People start up their chess computer and make the moves it says just to "win" and get rating points online. What these people don't understand is that it is not really their rating if they are cheating this way. What fun is it to just use a computer to try and win? I do not know what kind of satisfaction someone cheating like this gets from a game of chess. The following article talks about the specific case.

Text Messaging not admitted as evidence in cheating case

The judge ruled:

- Firstly, that “although he is not himself the subscriber to the telephone line [in question], Mr Marzolo enjoys the right to the confidentiality of the correspondence exchanged via this line, since its permanent use had been granted to him by the owner of the line, Ms. Pomian.”
- Secondly, that “no legal provision gave him the authority to waive this confidentiality”, unless the infringement involved “criminal or security matters.”
- Finally, the magistrate judged that “it would be unfair for Mr. Marzolo, Feller and Hauchard (…) to bear the full cost of the proceedings,” and he ruled that the FFE should reimburse part of the fees.

As it announced in a press release on January 27th, the FFE reserves the right to turn to the criminal courts, which could lift the confidentiality of correspondence.

It is a lot easier to cheat in chess tournaments now. Everyone has access to computers, many of the computers are so small they are sitting in our pockets. That is why being on a phone while you have a game going on is against tournament rules. It is easy to call someone else and ask them what move to make. Also, they could enter the moves themselves into a phone and see what move to make next. It is very sad that problems like these have to be brought to light. Hopefully if those players were cheating they are found guilty and the cheating is stopped.

Chess News of the Week - Programmers write open letter about Rybka-Fruit issue

Programmers write open letter about Rybka-Fruit issue

This is very interesting to me as a chess player who has used Fruit and as a Software Developer interested in open source.  This is very poor judgement by these guys if they did just steal the code.
 
 

Recently the author of Fruit, Fabien Letouzey, wrote an open letter to the computer chess community where he raised the concern that Rybka 1.0 beta may be a derivative of Fruit 2.1 in this public post.
Since then it has emerged from highly respected sources like Zach Wegner, Bob Hyatt and others that there is a lot of evidence that has been accumulated over the last few years that Rybka 1.0 beta is a derivative of Fruit 2.1.
Zach Wegner has presented evidence of alleged significant copied/derived Fruit evaluations in Rybka 1.0 beta here.

The large problem with these guys who stole the code was that Fruit was released under the GPL - part of the license states that any and all code contributed to a project after it uses GPL code is also now considered GPL.  That is a part of the deal when you use the code that people are making open.  Also you are required to publish any added or changed code.  If Rybka is guilty they are stealing from the public and selling what they stole instead of building on a project that was established as an open project.  It will be interesting to see how this procedes and if they are required to open their code and pay a fine.

Places to Play Chess online, Part 6

Chesscube is another newer site to online chess. I have found it to be a very good place to play. The flash interface is great - makes it easy to be available across all platforms without any need to download an interface. You get cubits from logging in and winning games that will allow you to get chess videos. The tournaments are available all the time and you get a game fairly quickly. The only thing I would want is an Adobe Air application of the interface so I could avoid having to open my browser.
Here is a description from their website:
Play chess online for free on ChessCube, the global community of chess players. Get chess videos and chess lectures, chat with friends, play live chess and ...

If you want an easy place to get to play, don't mind using flash in a browser to connect to the server and want an interface that is standardized ChessCube is a very good option for playing chess. I have found it very good - especially when I only have access to a browser on a computer it becomes very nice.

Upcoming Chess Tournament in Salt Lake City

Farewell Bobby Fischer Tournament
Tournament Flyer

There are 2 schedules - a 2 day and a 3 day schedule. There are 2 byes available as well. The time controls are fairly short - G/31 for the 2 day schedule and G/72 or G/64 for the 3 day schedule. Round 5 and 6 merge together and have longer time controls.

I have not been to one of these tournaments yet but this one sounds like fun. I might stop by and see how it is.

How to prepare for a Chess Tournament

What do you do to prepare for a tournament?  I am getting ready to get back into tournament play and I am looking for ideas on how to best prepare for it.  I have not played in a tournament for a good number of years - only played online recently.

I feel that I need more tactics study - but my gut is saying some endgame and opening would be useful too?

I did some Google searching and found an interesting link.

Roman Chess - How to prepare for a chess Tournament

This gives me some more ideas on how to prepare for a chess tournament.

1.  Play some slower games - if you only practice with speed chess it will be harder to player slower when you are in the tournament.

2.  Practice Tactics - this is very important and will help sharpen your game and help avoid simple blunders.

3. Decide on openings to play - don't go in and guess on which openings to play - you will not be able to prepare a lot of different openings and be strong in all of them.

4.  Study basic endgame ideas so you will be able to win or draw games in close situations.

5. Have fun and relax - it is all about enjoying the game anyways.

Favorite Chess Sites

What are everyone's favorite chess sites? Where do you like to play? Where do you like to study? Where do you like to find games?

It has been a while since I have posted - work and summer caught up to me and I had too many things going on. I am hoping to start posting regularly again. I have played a game now and then and watched my coworkers fight out some games while I worked and had lunch.

As for my favorite sites, I really like to play on freechess.org. I like Chesslab for finding games. I still have not found a prefered website for studying on, but I do like Chess Tactics Server and Chess Tempo.

Places to Play Chess online, part 5

Chessboss is a newcomer to the online chess arena. It is an all web interface - but it seems to be missing a lot of features. The biggest problem with Chessboss is the lack of players. Anyone can create and run a tournament which is nice. With the many other options it feels like Chessboss does not have a large enough following for one to have a good number of people to play with. But if you are looking for a quick casual game it might fit you.

Chess News of the Week - Anatoly Karpov out for a fight

Anatoly Karpov out for a fight - Telegraph
Karpov's lawyers, White & Case, are a global firm based in Manhattan. They seek nothing less than the disqualification of the incumbent FIDE President Kirsan Ilyumzhinov who is standing for a fifth term.

The rules demand that at least one member of a Presidential ticket be female and Ilyumzhinov's choice is American WIM Beatriz Marinello. Supporting documents indicate Ms Marinello was not nominated by the US Chess Federation but by her native Chile and Brazil. Karpov contends she is not even a member of either federation.

Karpov's lawyers also seek a ruling confirming he was nominated by the Russian Chess Federation. There is a supporting video of a meeting endorsing Karpov on May 14th. Subsequently the RCF was hijacked by Ilyumzhinov's supporters. Propaganda is very important at this stage as many smaller countries await events to be sure of being on the winning side. The election will be held this September during the Chess Olympiad in Khanty-Mansiysk.

Seems like an odd rule to me - but I have no problems with it.  I don't follow too much about the FIDE - but I do like Karpov.  I would love to see another Kasparov - Karpov match.  What I would like to happen is for the new FIDE president to push for chess in the Olympics.

Places to Play Chess online, part 4

Another good place to play chess online is Gameknot.com. There are some good things they provide. The teams are really cool, and the ladder is pretty nice as well. The problem with this site is that to get some of the nice features one must pay a pretty high membership fee. To be able to captain a team one must pay $60 a year. For that price it seems better to consider a Diamond chess.com account. You get a much better overall experience there. But if you are looking for another place to play some email games, Gameknot is fairly good.

Attacking Chess Opening Overview - Reti Gambit

Overview
This gambit against the French is not very well know and has not had a large amount of popularity.  It is slowly gaining players who like and - and there are some GMs are also playing it.  It is a fun chess opening that is played against the French defense.  The most recent book on it was written by Thomas Johansson and is called The Fascinating Reti Gambit.

History
The gambit was first played by Reti just before he switched from 1.e4 to playing 1.Nf3.  Sad to say that he did not continue playing the variation and it was fairly obscure for a long time.  In the 90s a number of GMs starting playing the variation.  Most players of the French Defense look down on it and most books only give a line on it and say Black as equality or an advantage.

Moves
The gambit starts out like this.  1.e4 e6 2. b3


This takes Black out of his standard French play and White ends up playing a gambit.  The main line plays as follows:

2... d5 3. Bb2 dxe4 4.Nc3 Nf6 5.Qe2 Bb4 6.O-O-O Qe7 7.Kb1 Ndb7 8.g4 O-O 9. g5 Nd5 10. Nxe4


Common Tactics
  1. Opposite side castling - this often leads to crazy attacks where White and Black try to mate each other first.
  2. g4-g5 - This attack often forces the Black knight to a less than ideal location.
  3. Bg2 will give White more influence in the center and often wins back the sacrificed pawn.
Summary
The main purpose behind the gambit is to throw Black into a tactical game instead of the many quiet games that they can have playing the French defense. The game is much more open than the standard French defense, and with opposite side castling it is sure to have both sides attacking. The Reti Gambit is very interesting and the games are full of interesting tactical ideas.

Chess News of the week - Nepal Chess Association granted membership to Nepal Olympic Committee

MYREPUBLICA.com - News in Nepal: Fast, Full & Factual
KATHMANDU, July 5: Nepal Olympic Committee (NOC) granted its associate membership to Cricket Association of Nepal (CAN) and Nepal Chess Association.

An NOC meeting has endorsed the requests by the respective associations for membership recently on the basis of participation of the games in regional and continental tournaments and their popularity in Nepal.


"We have consulted international authorities and decided to grant the membership," said NOC President Dhruba Bahadur Pradhan at a press conference on Monday.

This is the first time NOC has added members after its establishment.

"International Cricket Council is already in Olympic movement and we are also participating in tournaments like SAG and Asian Games. We are not separate from the Olympic movement," said CAN President Binaya Raj Pandey. Likewise, Nepal Chess Association President Rajesh Hari Joshi thanked NOC for the membership.
Would be fun to see chess in the World Olympics.    Maybe have speed chess or game/30 to keep the speed interesting for spectators.  I remember seeing some chess matches that were covered on PBS on year.

Places to Play Chess online, part 3

One of the more popular places to play online chess is the Internet Chess Club.
It has been around for a long time.  ICC and FICS split many years ago when the internet was in its infancy.  FICS wanted to provide a free place to play chess while the ICC wanted to provide some services which had a cost.  Both are good sites and provide a good service.  ICC has a lot more players on normally, and there are some other benefits to the service.  The problem is the cost.  It costs $70 a year for a membership.  The price seems very high and it has kept me from playing there since there are many other places to play.

If the $70 a year is not a problem, ICC provides good services and has a good number of players to play against.  You get access to chess.fm - videos teaching chess.  Personally - I play at FICS and chess.com for free.

See my previous posts for more places to play chess online.
