Hello again, I wish to extract the 6 first positions of every game of a pgn file.
I want to create a personal opening book. I played around pgn-extract with no success, Can someone help me?

What exactly do you mean by "position?"

For example, is the first position the way the board looks after White's first move? Or is the first position the way the board looks after both White and Black makes a move?

Also, are you looking for the positions to be represented graphically and if so, what format? (png, gif, jpeg, etc.) Or would you like to see a FEN of the position?

Maybe you mean you want to extra the first six MOVES of a pgn file? (I think that makes more sense.) And if so, you're looking for an extract of the notation, correct?

Yes I want to mean the first six moves of every game of a pgn file and create a new one pgn file with only the first 6 moves of the games... sorry I'm not english native and also newbie at chess...
How can I do this?

Well, I know of no existing software program that will do this, but this is an easy program to write, in any language, if you're a programmer.

Basically, you just open the original PGN file for input, read and print to a new file the PGN tags, read and print the first six moves, and then go on to the next file. Continue until end of file. Done.

If you're not a programmer, just about everybody knows someone who they go to when they have a computer problem. Your own "computer guru" will almost surely be able to handle this simple programming task. Ask him (or her) to write it for you.

(I'd do it, but I'm currently in the middle of writing three other programs.)

If your PGN file isn't too large, I suppose you could always do it by hand, within TextPad, or your favorite text editor.
