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, ...

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. ...

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.

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 ...

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 / ...

"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 ...

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 ...

Here are some of Annotated game archives I found: GameKnot Annotated Games ChessGames.com Annotated Archive PGN Mentor Use this method to search for annotated games: Search for annotated games Will add more when I find them.

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

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 ...

Stockfish works well for this purpose; and it's free software.

Wikibook Chess Opening Theory has similar aims but I don't think it quite meets all of your requirements. Still, it's the website closest to meeting them that I can think of, so I hope it helps. Being a wiki, it's still evolving and of course one can always wonder about the expertise of the authors.

Thanks for your answers. I have contacted chessbase and they told me that training annotation is not supported in pgn files but just in their original database format cbh. So, there is nothing to be done about this problem.

It's a bit of hyperbole to be sure. I can't think of many cases where such a phrase would be used. Normally, "...and wins" is good enough. But it means there's no conceivable way that White will lose the game and it takes no special skill to finish the game. The opposite phrase is Black's position is "dead lost." I have also seen in print "black should ...

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 "....

Here are a bunch, although they are supposed to be used with a defunct product called ChessVU: http://www.angelfire.com/games3/smartbridge/ Note the huge and deeply annotated middle-game database. Edit: I have since tried some of these games out with SCID vs. PC, and it works great. That middle-game tutorial seems to be a really great resource; and there ...

Chessbase is top of the line, but there are a lot of alternatives: Hiarcs Chess Explorer, the Shredder GUIs, Aquarium, Chess Assistant and Chesspartner. Arena is free, but has a few of the menu items in German, and is perhaps more for playing engines than analysis. Other free ones are Chesspad, Kvetka, Penguin and Tarrasch. SCID is pretty good for a free ...

The old Fritz 5.32 (last free version) does this. Of course it is not as powerful as the latest version (big understatement). It is available here http://freechess.50webs.com/fritz.html but note that it will need some work (described on the website) to get it to run on modern versions of Windows. I alternate between Fritz 8, which is not quite as old as the ...

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 ...

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.

As well as books, video presentations a lot of times presenters will say "d e" instead of saying "d takes e" I am trying to provide you with another example of its usage...it appears rather commonly in spoken word as well as text.

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....

It surely is a measure of the quality of play, the deviation of the game from a "perfect game", as understood by the engine used in the analysis. A perfect move will lose zero units of measure. I couldn't find a chessbase source, but here it is a similar question on lichess, in which the unit of measure is called a centipawn: https://lichess.org/qa/103/...

Descriptive Notation. It is an alternative notation for recording chess games. From Wikipedia: Descriptive notation is a notation for recording chess games, and at one time was the most popular notation in English- and Spanish-speaking countries (Brace 1977:79–80) (Sunnucks 1970:325). It was used in Europe until it was superseded by algebraic ...
