can you please help a newbie

how do i post games

it says my FEN string and PGN are invalid

Post your fen/pgn here and someone can probably take a look.

6k1/p6p/1p6/4P3/2P2Q2/8/PP4PP/6K1 b - -

That's the FEN String that's giving him trouble -- if he could explain, he wouldn't have asked for help.

so can anyone help on why it is invalid

No idea. It inputs perfectly well to any one of my chess engines. Here is the position, tell me if it is correct:

If this is the position, and chess.com is not accepting it, then it is probably a bug.

i was wanting the whole game

A FEN code is only a recording of a single position, not a whole game. You need to use the PGN for that. Alternatively, input the moves manually from the starting position.

oh ok thanks

For some reason the chess wizard will only accept fen strings which have 0 1 or 0 1 or something like that at the end, although I have no idea what that is supposed to mean. I inputted the FEN with 0 1 and with 1 0 and it made no difference.

Nytik's diagram is slightly off. The b at the end of your FEN means that it is black to move, not white. This is what it should look like:

I apologise Oinquarki (and CUrules12) when I created the diagram I paid no heed to the telling b. I beg for your forgiveness!

It is odd that it won't accept - - though. To satisfy your curiosity, Oinquarki, the second-to-last number at the end is the number of halfmoves since the last pawn move/capture, and the final number is the number of moves in the game (up to that position.)

From wikii:

"A FEN record contains six fields. The separator between fields is a space. The fields are:

1. Piece placement (from white's perspective). Each rank is described, starting with rank 8 and ending with rank 1; within each rank, the contents of each square are described from file a through file h. Following the Standard Algebraic Notation (SAN), each piece is identified by a single letter taken from the standard English names (pawn = "P", knight = "N", bishop = "B", rook = "R", queen = "Q" and king = "K")^[1]. White pieces are designated using upper-case letters ("PNBRQK") while Black take lowercase ("pnbrqk"). Blank squares are noted using digits 1 through 8 (the number of blank squares), and "/" separate ranks.
2. Active color. "w" means white moves next, "b" means black.
3. Castling availability. If neither side can castle, this is "–". Otherwise, this has one or more letters: "K" (White can castle kingside), "Q" (White can castle queenside), "k" (Black can castle kingside), and/or "q" (Black can castle queenside). If both can castle both sides, it is "KQkq"
4. En passant target square in algebraic notation. If there's no en passant target square, this is "–". If a pawn has just made a 2-square move, this is the position "behind" the pawn.
5. Halfmove clock: This is the number of halfmoves since the last pawn advance or capture. This is used to determine if a draw can be claimed under the fifty-move rule. Usually 0
6. Fullmove number: The number of the full move. It starts at 1, and is incremented after Black's move."

There should be a space after dot in whites' move "1.  d4" not "1.d4", but no space for black's starting move "3...d4".

when inputting FEN record in PGN, the format is

[FEN "FEN string"] note: no = sign: [FEN ="FEN string"] is wrong.

In the example you have provided, the last ingredient (starting move) is missing. Incomplete strings will not work in chess.com

So your string should have been 6k1/p6p/1p6/4P3/2P2Q2/8/PP4PP/6K1 b - - 1

and use in PGN file should be

[FEN "6k1/p6p/1p6/4P3/2P2Q2/8/PP4PP/6K1 b - - 1"]

assuming you started with move 1. If your start move is 33, it should be

[FEN "6k1/p6p/1p6/4P3/2P2Q2/8/PP4PP/6K1 b - - 33"]

and your moves should begin with 33...
