What does “+-” mean in algebraic notation? This symbol means "White has decisive advantage", which means that White's advantage is big enough to secure him victory. As for symbol -+ it means "Black has decisive advantage". What does this notation mean? This notation is introduced to bypass the language barrier so any reader ( Japanese, English, Arabian, ...

Wikipedia says the following: Exclamation points ("!") indicate good moves—especially ones which are surprising or involve particular skill. Hence annotators are usually somewhat conservative with the use of this symbol. (emphasis mine). 2. c4 is the most played move after 1. d4 d5, therefore it doesn't receive an exclamation mark.

There are blogs and news sites that regularly publish analysis of recent games. Chess24 also provides a lot of videos with analysis of games, competing in that regard with various youtube channels. You can also find annotated games on Chessgames.com, most easily in the form of game collections via google "site:chessgames.com annotated".

After reading a bunch of open source code, I just found out that most of them are relying on Chesspresso which is a solid Java Chess library that can handle move validation, PGN parser (what I was looking for), chessboard renderering, etc. The code is well-documented and easy to understand. It took me around 30 minutes to read the code and start testing. ...

To try to give a concrete example consider Sax-Seirawan, Brussels 1988 [Event "World Cup"] [Site "Brussels"] [Date "1988.??.??"] [Round "?"] [White "Sax, Gyula"] [Black "Seirawan, Yasser"] [Result "1/2-1/2"] [WhiteElo "2610"] [BlackElo "2595"] [ECO "B09"] [FEN ...

The first time you see a player doing this you should warn him and make him catch up on his time. If you are watching the game closely it is likely that there will only be 2 or 3 moves to make up. Note that he need not write after every move but must not make a move if he has not written his previous move. In that case, particularly with a blitz finish you ...

I think you did a great job there of annotating your game. If you have a coach (or an analysis buddy) and you were to show them that then they would get a big head start in identifying problems in your game and helping you to improve. Chess is a game of challenge. You make your moves on the board but then so does your opponent and his moves challenge yours. ...

A blunder is a game-changing move. Nb8 does not change the result of the game which is utterly and completely lost regardless of black's move. Earlier in the game black did blunder when it gave away its queen. The reason for the "!" part of the "?!" (dubious move) notation in this case is because moving the knight opens up the line of ...

As a native Russian player I may assure you that we always used the suggested notation, e.g. Фd4 or Лd1 (Ф - ферзь - for Queen, Л - ладья - for Rook, etc); even the 6 years old beginners did so. Nobody ever was insane enough to suggest Russian alphabet for encoding files.

"Wins by force" means that the move leads to a series of moves that makes it impossible for the losing side to defend the position. Here, the definition of "winning" can vary between annotators. Checkmate is the extreme case of winning. Having an advantage of two pawns without any compensation for the opponent is somewhere at the low end of a winning ...

de and fe are normal pawn captures. There is no contradiction in writing de and NxB and Nxe5. The "x" is optional. It would be unusual and inconsistent to write 4. BxNc6 and 4. ... Nc6 in the following - 1. e4 e5 2. Nf3 Nc6 3. Bb5 Nge7 4. BxNc6 Nc6 but if we put it in fen then it works - [FEN ""] 1. e4 e5 2. Nf3 Nc6 3. Bb5 Nge7 4. BxNc6 Nc6 Note what ...

Tal vs Botvinnik 1960 is very good as Tal is quite verbose in commentary and what he was thinking about during the game. In addition to the benefits you mentioned, the annotations help you understand what strong players think about in different positions and how they approach the game. Particularly useful is the strong player's positional understanding and ...

I occasionally see annotations/commentary where a move / line is said to make (for example) white win "by force". I am unsure if it has the general sense of "this move initiates a forcing sequence where white will come out on top" or something more specific, say, "with this move, white exerts indefensible pressure ('force') on a particular square / ...

YouTube is a good resource to consider. There is one user in particular that annotates miniatures rather well for beginners, and as a bonus, he sounds like Dracula. https://www.youtube.com/user/MatoJelic

Visualization usually improves as you get stronger, and there are exercises that can be done to improve it. When following lines in a book, most players use a board, and sometimes two. The second one is used to explore those side variations, without having to constantly reset the board and play from the first move. This can be done with either physical ...

Should it be a verbal warning and loss of the game on a subsequent attempt or something else? It depends entirely on the circumstances, although a player would never be defaulted for the specific reason of writing the move before playing it. (I will return to this point at the end) A big part of the problem is that years ago young players were taught to ...

Chessbase meets all your criteria and more. For example, it also allows you to look up any position in a reference database, see the main moves other people have analyzed, etc. The downside is the price, so if want a cheaper option you could look into Fritz - it should also meet your criteria, although the price is still relatively high. Even if you don't ...

You made a mistake when transcribing move 7. It is 7. Qh5+, not 7. Qf3+. Move 10 is then Qh5f7, which is not blocked by the Nf6. [FEN ""] 1. e4 Nf6 2. e5 Nd5 3. d4 d6 4. Nf3 dxe5 5. Nxe5 Nd7 6. Nxf7 Kxf7 7. Qh5+ Ke6 8. c4 N5f6 9. d5+ Kd6 10. Qf7 Ne5

The best annotated PGN game collections I found were added to my website after searching for days, see Annotated PGN file download page I added 950+ annotated games and every world championship match game ever played. You can get a good free PGN reader app from there too, which comes with Stockfish built in. If any one knows about any other annotated "....

I'm glad some have found the downloadable annotated PGN game archives at Path to Chess Mastery - https://pathtochessmastery.blogspot.com/ - useful. Although the individual game analyses (my own tournament games and commentary on Master games) have been posted on the blog for training purposes, I think a number of the positional and tactical insights gained ...

"D" means see diagram. "+/-" means white is better, but not much better.

You could use chesslib. In the README file there is an example of how to load and walk through all the moves from all the games in the PGN file: PgnHolder pgn = new PgnHolder("/opt/games/linares_2002.pgn"); pgn.loadPgn(); for (Game game: pgn.getGame()) { game.loadMoveText(); MoveList moves = game.getHalfMoves(); Board ...

In Chessbase, copy the games to a temp database, right click the file, go to tools and select Unannotate db, then copy to the games to a pgn file. Edited to note Unannotate doesn't work on pgn files directly.

You can't do this in PGN, not the way you want it. There are some tricks that publishers (especially Everyman) use to create their "PGN ebooks": They split the book over many different PGN games. You'd say "Here I remembered an earlier game that had a similar position; see X vs Y after this game." A variation that starts at move 1 has to start at move 1: 1....

An artificial move is one that does not fit in with what would be typical of the plan. It means "unnatural" given the position. In the game above, Bg4 is unusual, and only played 5.5% of the time in that position. Typically, 10...cxd4 is played there in an overwhelming majority of games, and the Bc8 often ends up on the d7 square as more suitable.

I agree with @InertialIgnorance Chessbase is very useful and good. I have also used chess database software which have the advantage of being free: Scid ("Shane's Chess Information Database") is a free and open source UNIX, Windows, Linux, and Mac application for viewing and maintaining huge databases of chess games Scidb, is a free chess database ...

Exclamation (!) is a highlight in analysis. Either it indicates strong move, or it is also possible to indicate unexpected move. Something to which opponent is totally unprepared. Something which will be followed by inaccuracy (?). This could be different depending on what exact game it is. What will follow after provoking move? Exclamated move could be not ...

I got in touch with Bill Forster, the developer who created the software, and this is what he replied. It worked for me so I hope it will be useful for somebody else: I did some experiments with your use case and I admit it is hardly obvious how Tarrasch is handling your quite reasonable attempts - in fact what you are doing should really work, so ...
