A NOTE ABOUT FEN:

 

FEN Specification and Implementation Guide - Revised: 1994.03.12

Authors: Interested readers of the Internet newsgroup rec.games.chess

Coordinator: Steven J. Edwards (send comments to sje@world.std.com)

16.1: FEN

FEN is "Forsyth-Edwards Notation"; it is a standard for describing chess positions using the ASCII character set. 

A single FEN record uses one text line of variable length composed of six data fields.  The first four fields of the FEN specification are the same as the first four fields of the EPD specification.  

A text file composed exclusively of FEN data records should have a file name with the suffix ".fen".

16.1.1: History

FEN is based on a 19th century standard for position recording designed by the Scotsman David Forsyth, a newspaper journalist.  The original Forsyth standard has been slightly extended for use with chess software by Steven Edwards with

assistance from commentators on the Internet.  This new standard, FEN, was first implemented in Edwards' SAN Kit.

16.1.2: Uses for a position notation

Having a standard position notation is particularly important for chess programmers as it allows them to share position databases.  For example, there exist standard position notation databases with many of the classical benchmark tests for chessplaying programs, and by using a common position notation format many hours of tedious data entry can be saved.  Additionally, a position notation can be useful for page layout programs and for confirming position status for e-mail competition.

Many interesting chess problem sets represented using FEN can be found at the chess.uoknor.edu ftp site in the directory pub/chess/SAN_testsuites.  

16.1.3: Data fields

FEN specifies the piece placement, the active color, the castling availability, the en passant target square, the halfmove clock, and the fullmove number. These can all fit on a single text line in an easily read format.  The length of a FEN position description varies somewhat according to the position. In some cases, the description could be eighty or more characters in length and so may not fit conveniently on some displays.  However, these positions aren't too common 

A FEN description has six fields.  Each field is composed only of non-blank printing ASCII characters.  Adjacent fields are separated by a single ASCII space character.

16.1.3.1: Piece placement data 

The first field represents the placement of the pieces on the board.  The board contents are specified starting with the eighth rank and ending with the first rank.  For each rank, the squares are specified from file a to file h.  White pieces are identified by uppercase SAN piece letters ("PNBRQK") and black pieces are identified by lowercase SAN piece letters ("pnbrqk").  Empty squares are represented by the digits one through eight; the digit used represents the count of contiguous empty squares along a rank.  A solidus character "/" is used to separate data of adjacent ranks.

16.1.3.2: Active color

The second field represents the active color.  A lower case "w" is used if White is to move; a lower case "b" is used if Black is the active player.

16.1.3.3: Castling availability

The third field represents castling availability.  This indicates potential future castling that may of may not be possible at the moment due to blocking pieces or enemy attacks.  If there is no castling availability for either side, the single character symbol "-" is used.  Otherwise, a combination of from one to four characters are present.  If White has kingside castling availability, the uppercase letter "K" appears.  If White has queenside castling availability, the uppercase letter "Q" appears.  If Black has kingside castling availability, the lowercase letter "k" appears.  If Black has queenside castling availability, then the lowercase letter "q" appears.  Those letters which appear will be ordered first uppercase before lowercase and second kingside before queenside.  There is no white space between the letters.  

16.1.3.4: En passant target square

The fourth field is the en passant target square.  If there is no en passant target square then the single character symbol "-" appears.  If there is an en passant target square then is represented by a lowercase file character immediately followed by a rank digit.  Obviously, the rank digit will be "3" following a white pawn double advance (Black is the active color) or else be the digit "6" after a black pawn double advance (White being the active color). An en passant target square is given if and only if the last move was a pawn advance of two squares.  Therefore, an en passant target square field may have a square name even if there is no pawn of the opposing side that may immediately execute the en passant capture.

16.1.3.5: Halfmove clock

 The fifth field is a nonnegative integer representing the halfmove clock.  This number is the count of halfmoves (or ply) since the last pawn advance or capturing move.  This value is used for the fifty move draw rule.  

16.1.3.6: Fullmove number

The sixth and last field is a positive integer that gives the fullmove number. This will have the value "1" for the first move of a game for both White and Black.  It is incremented by one immediately after each move by Black.

16.1.4: Examples

Here's the FEN for the starting position: rnbqkbnr/pppppppp/8/8/8/8/PPPPPPPP/RNBQKBNR w KQkq - 0 1 

And after the move 1. e4: rnbqkbnr/pppppppp/8/8/4P3/8/PPPP1PPP/RNBQKBNR b KQkq e3 0 1  

And then after 1. ... c5: rnbqkbnr/pp1ppppp/8/2p5/4P3/8/PPPP1PPP/RNBQKBNR w KQkq c6 0 2

 And then after 2. Nf3: rnbqkbnr/pp1ppppp/8/2p5/4P3/5N2/PPPP1PPP/RNBQKB1R b KQkq - 1 2

For two kings on their home squares and a white pawn on e2 (White to move) with thirty eight full moves played with five halfmoves since the last pawn move or capture4k3/8/8/8/8/8/4P3/4K3 w - - 5 39

A Note for Chess Programmers:

Several chess programs have an incovenient window to setup the board position. Please CLICK HERE to see a relevant page about this problem.



How to play - Evaluation of position

How to play with evaluation of your position

A player asks himself: What is my best move now? The answer is making an Evaluation of your position and then decide what to do!

An experience player makes the evaluation of the position subconsciously (this in any game, as well as in chess). After several years of chess playing the evaluation comes automatically. However, if you do not have such an experience the main steps to follow are:

What are your advantages/disadvantages in a given moment of the game? Here is a checklist:

 

CHECK LIST

 

1

Check Material (yours and opponent's)

 

2

Check your King Safety (Discovered attack, Forks and distant enemy Knights threats). If you castled, what pawns are protecting your King and would you need at this stage an a3 or h3 (a6, h6 for black) for escape, to avoid checkmating of your King at the 1st or 8th rank.

 

3

Look the pawn structure and weak points (islands). Is any pawn of yours candidate for a promotion? Does it have any support?

 

4

Who controls spaces and the centre? Can you do something to block opponent there?

 

5

Can you check ranks, files and diagonals? What are the opportunities for you and your opponent?

 

6

Do you see an active placement of the pieces (yours and opponent's)? Active means to create threats immediately or set them and wait.

 

7

Do you need to attack or better wait for opponent to make a rather forced (undesired for him) move?

 

8

Check if there was a strange move from your opponent. There is always something behind them. Is he going to fork you?

 

9

Check colour of a threatening Bishop. Prefer to move in a different colour if possible.

 

10

Finally check who has advantage in tempo (normally the one who is not moving his pieces back and forward)

 

 There is an 11th rule under discussion: Can you ruin your opponent's capability for castling?

------------------------

A GENERAL RULE: You must attack to win. When you see that you are better positioned you must attack. Otherwise you will soon lose the advantage. Needless to say that you have to find opponent's weakest spot and attack, even if the spot is not this moment the King' s surrounding area of the opponent.

Setting the KNIGHTS in a real game: A good advice (David. S.) is to set the Knights to always face towards their monarchs at the beginning of the game, and then stay that way for the remainder of the game.  How else can we tell which is the King's Knight and which the Queen's Knight?

------------------------

EXERCISE

In your PGN viewer or Chess playing software open a game e.g. Kasparov vs. Someone, etc. and go to a move at the start of the middlegame (around let's say after move 12). Stay there at a given position and pretend to play with white. Take a deep look and count the time you need to do all the checks for the evaluation of the current position as we mentioned above.

How long did it take? Did you now decided for a move? Did you forget something, e.g. did you check the diagonals?  OK! How compliant is your decision for the next move with that of the Grandmaster. Check it also with an Engine analysis. Try again a second example. Make a hobby out of it when you have time. Soon the process will run automatically in your brain each time you have to play after a move of your opponent.

Now, tell me how did you find this exercise. Is it effective? Would you suggest something additional or different? Write to me at eurocon2000@hotmail.com

The game of Chess: A nice Introduction is presented by Mr Mark A. Lowery and you can see his web page at:  http://chess.markalowery.net/index.html .

PS: Using Chess Engines?   There are up to now approx. 155 well known chess engines to load in various chess playing software (GUIs). Of these Engines, 99 were produced in the European Union and 21 in the United States.

possible.

 



Blindfold Chess

 
WHAT IS BLINDFOLD?
 
Blindfold is a way to play without seeing a chessboard or without any chessboard at all! The ability to develop is that you have to memorise all of your moves and those of your opponent. It requires some skills of pattern imagination. Not all are capable to do that. Maybe it is possible for players above 2,200 elo. However, you have to test yourself if you have this natural gift to easily memorise moves.

What is the idea of blindfold chess? Well, if you learn to climb a mountain with a rucksack on your back of about 15 Kg, then without this burden you will climb the mountain easier. This is the reply. Besides, it sounds like a joke, if you are in a crowded Bus with a chessfriend commuting home you can play a game with him, simply talking one to the other. Further, your chessfriend may ask you: tell me about your recent game at the Club? You need to answer something.

Some blindfold chess players can play at the same time with more against 10 different players or even more.

How to exercise to play blindfold?

There are apparently two means:

1)      Reading chess papers: Find those miniature real games from books or in the web (Google search: chess miniature games) that are finished in 7 to 20 moves. Try to imagine how the pieces are moving. However, there is a more concrete method.

      Click HERE to see a nice list of short games. Follow the suggestion to print parts of the page for your exercise. It is simple and very effective. 

2)    Using Chess Software: First of all you must know a priori the co-ordinates if of white or black squares. For example, e5 is white or black? Download Winboard chess. In the Options, General select Blindfold. The Board becomes blank. Load an engine and start playing against it. You will see the notation of the opponent’ s moves on top at the messages. At a certain point the software will tell you that you made an illegal move!

Return to Options, General and unselect Blindfold. The game you played appears with the pieces on the board. Play back the game and see what you did. Check the number of moves you reached e.g. 8 and write it down. Restart again changing opening (ECO) and see at what move you get now the illegal move. When you have reached freely up to 30 moves come back here and teach us what to do! (provided the engine has not checkmated you, so better get a weak engine or get Delfi and set in its ini file the lowest strength and set 1 sec response time at Options-Time Control of Winboard that is 60 moves in 1 minute).

      If you feel comfortable to try other options, try this. Play a game till the end of 

      the middlegame and then turn the board to blindfold to play the endgame.

     

      You can also play Blindfold with ARENA free Chess Software (see the How-To pages)

      Details with Arena: 1) First save your curent appearence before any change. go to

      Options >Appearence and select tab Istallation. There click Save Appearence (e.g. as   

       Standard) , press APPLY and OK. The setting is saved as a file with the extension cfg.

      2) Then go to: Options>Appearence>Pieces  and select Diagram fonts: Diagram TTBlindALL 

      or DiagramTTBlindBlack or DiagramTTBlindwhite then press APPLY and OK.

      Stay in Options>Appearence and select tab Istallation. There click Save Appearence (e.g. as

      BlindfoldALL) , press APPLY and OK.  3) Return and load from Options>Appearence your

      standard settings. When you want to play BLINDFOLD got to Menu>Options>Load

      Appearence... press and select BLINDFOLD. When you have finished your blindfold game, go

      back to Menu>Options>Load Appearence... press and select your Standard settings.

     

      TRAINING: You can "hear" a blindfold game in ARENA if you load an engine and you press

      the 'IC engine button' to make a moves from both sides. The moves are announced but you 

      cannot see them (hide the engine moves list). With some engines you can use the

      spacebar to start-stop the engine and hear the moves.    

      


 

      Another free software you can download and try for blindfold is Jester

      (java). In this you can hide either white or black pieces or both (on and off).

 

You can try to play Blindfold with JESTER right here:

Win Time

Some people are mislead into thinking that playing chess is a 'waste of time'. Our view is that:

Playing chess teaches you logic, visualization skills, strategy and implementation, improves your memory, priorities, essential planning skills, patience, determination, anticipation, sport behaviour and much more. It is also teaching you to set ..... traps!

Therefore, playing Chess is not a loss but a Win of Time, if we can call it so!
