PGN

I don't know how PGN notation works. Can you help me?

what's your question?

I want to know how PGN notation works.

the first bit for each move pair is the move number followed by a "."

pawn moves are letters and numbers specifying the ending square (1.e4

Rook moves start with "R", Bishop moves start with "B", Knight moves start with "N", Queen moves with "Q" and King moves with "K". A capture is denoted with an "x"

So "1.e4 e5 2.Nf3 Nc6" is where white moves his kings pawn out to the fourth rank, and then moves his king side knight in front of his bishop and black brings his queen side knight in front of his bishop.

if there is any ambiguity as to which piece is moving, it is specified  more exactly (like Rbd7 or R6d7) if there are two pieces which can end up on the same square.

there's a decent explanantion on wikipedia

PGN is a file that contains the moves of a game, along with some other information. The file can be read by  "viewers" and the game  can then be replayed, or even edited.

In order to use a pgn, you will need to downoad and install a viewer such as Winboard or possibly even use a chess program.
