O-O-O is correct. in vote chess games, it says,

You voted for O-O-O, or O-O

using the O's, and not the zeros.

To make pgn compatible at times, you can use windows Notepad to edit the file (you may have to first rename it as a .txt file, then rename it back to a .pgn file after editting).

So, let me get this straight. You are saying that chess.com has more authority on the rules of chess than FIDE? -__- I cannot believe this...

The first is zeroes, the second is capital "o"s. Just wondering...

Gotta love the OP, not even refering to any specific chess notation. The way it used to be done was with castle and castle long. This stands for castling kingside and castling queenside respectively. I have never had to forefit a game because of using this notation. Let us assume you mean algebraic. If you want to know whether it is used with an O or a 0 (zero), read your FIDE handbook, appendix C, I think it is. They use zeros. However, if you were refering to ICCF notation 5171 is castling kingside, and 5131 is castling queenside.

You use 0 as in zero. Go look at the FIDE handbook. I mean it. Go now! No time to waste. It clearly doesn't have any O nonsense in there. I quote my friend TheMagicianKing, because he has the right idea. I don't think I've heard an argument for why the letter O should be used other than something along the lines of "my engine says so" or "the pgn to my game says so". Seriously? You patzers probably use your engines as if it gives you sight. If you are seriously intent on it being the letter O, than I ask you to give me a reputable chess organization that endorses O-O, as opposed to the more correct 0-0. I know FIDE and USCF are backing me up. While your reputable source is your computer playing program? Anyways, it would not make since to use a letter to represent castling.

I've always used O's.

calm down, guys. i have figured this out!

as our dear friends dzikus and themagicianking pointed out (respectively):

the pgn specification specifically says that it's the letter O.
the fide handbook uses a number 0.

so - when you are playing on the internet, you use the letter O, and when you are playing OTB, you use the number 0. case solved!

Gee, settle down, guy! Too much caffeine tonight?

You're right about the FIDE rules...Bully for you!

However, you're wrong about the USCF rules. If you have a USCF rule book handy, just take a glance at rule 38.A.8 (page 217 of the 5th edition).

And you obviously haven't read Section 8.2.3.3 of the "Portable Game Notation Specification and Implementation Guide".

But that's OK, I know what it feels like when you've had a whole pot of coffee.

In case anyone is interested, here's the full text of Section 8.2.3.3 of the PGN spec:

```"8.2.3.3: Basic SAN move construction

A basic SAN move is given by listing the moving piece letter (omitted for
pawns) followed by the destination square.  Capture moves are denoted by the
lower case letter "x" immediately prior to the destination square; pawn
captures include the file letter of the originating square of the capturing
pawn immediately prior to the "x" character.

SAN kingside castling is indicated by the sequence "O-O"; queenside castling is
indicated by the sequence "O-O-O".  Note that the upper case letter "O" is
used, not the digit zero.  The use of a zero character is not only incompatible
with traditional text practices, but it can also confuse parsing algorithms
which also have to understand about move numbers and game termination markers.
Also note that the use of the letter "O" is consistent with the practice of
having all chess move symbols start with a letter; also, it follows the
convention that all non-pwn move symbols start with an upper case letter.

En passant captures do not have any special notation; they are formed as if the
captured pawn were on the capturing pawn's destination square.  Pawn promotions
are denoted by the equal sign "=" immediately following the destination square
with a promoted piece letter (indicating one of knight, bishop, rook, or queen)
immediately following the equal sign.  As above, the piece letter is in upper
case."My opinion is that if you're just putting it down on a scoresheet, who's gonna care? But if it's information that's going to end up in a PGN file, it really needs to be the capital letter O.```

PGN uses the uppercase letter O but, FIDE uses the digit zero. Why? I don't know. But, there it is.

Double zero is a typical WC sign. So, if castling is a good move - it should be O-O. Otherwise - apparently 00.

The same for long castling.

Maybe we should just use a plain king move...Kg1 when white's king is sitting on e1 is obvious enough ;).

I'd also like to mention that in the FIDE handbook, although it first shows the notation for kingside castling as being "0 - 0", their usage is inconsistent and thus cannot be considered decisive. If you scroll down the page to the section regarding Chess960, we see:

"Thus, after c-side castling (notated as O-O-O and known as queen-side castling in orthodox chess), the King is on the c-square (c1 for White and c8 for Black) and the Rook is on the d-square (d1 for White and d8 for Black). After g-side castling (notated as O-O and known as king-side castling in orthodox chess), the King is on the g-square (g1 for White and g8 for Black) and the Rook is on the f-square (f1 for White and f8 for Black)."

In this case, the FIDE handbook stated that the 'O' was used, not the '0'.

Okay...So many conflicting views. :(

Use the letter O, as in the first reply. You're not going to get penalized by FIDE because your ovals are too fat, but your PC may not read it if you use zeros.

The way I opened it was to right-click the .pgn file and click Open With.  Then select notepad.
