    For the PGN?:> hehe sorry don't follow you.

    The PGN text goes into the post buy it looks very complicated and eventually a blank screen comes out. It's the same when I try to load my Rybka file in a chessviewer like Winboard- I think the Rybka variation-giving messes it around.

    For example:

    game with this move. Qg4 with tempo means a game-long kingside attack, and the
    white game plays itself with Nf3, Be3, Qh3 & g4. Rybka is misleading and will
    give the position = (with perfect play) but for a human all the tactics will
    be with white and the advantage is clear. Black's best 6th move is a waiting
    move, for example Nc6. White can respond with Nf3, blocking Qg4 with tempo and
    the bishop can safely take on c5 and black has equalised, or white can respond
    with Be3, after which black plays another waiting move, Qa5 (threatening d4) &
    again waiting for the knight to block Qg4 before he brings the bishop into the
    game.} 7. Qg4 O-O 8. Nf3 Nc6 9. Bd3 f5 10. Qh3 h6 $2 $146 {An understandable
    move, however Nd4 (achieving the same protecting of e6) is very strong for
    black. After any knight trade black has a very annoying Bishop!} 11. g4 {Most
    sequences that follow rely on exchanging B & N which serves 2 purposes: 1) The
    white N gets to d4 with tempo, 2) the f5 square is cleared for an eventual
    f4-f5 push and Bishop h6-sac. (Or, if exf the the plan will be to simply
    exploit the protected passed pawn and the black isolated pawn.) The moves a3/
    b4 are probably superfluous as I could have just played Nc3-e2-d4 and won
    control of g1 for the rook anyhow. An alternate plan for white could involve
    a6, Bd2, 0-0-0. With g4 later after attempting to swap off the dark squared
    B's. Might be too slow though. Rybka gives g4.} Nd4 $6 {An error in strategy?
    Black must try to exploit his mobility advantage on the Queen side. The best
    plan to achieve this is Nb4! When white has no choice but to weaken his Q-side
    pawn structure after black swaps the knight for the bishop. Here's a good
    example of the weakenning then exploiting a Q-side structure/mobility
    advantage from another Corr. game i'm playing: http://www.*******.com.au/
    showthread.php?p=24269&posted=1#post24269 Moves 10-15 show pretty clearly the
    black idea with the sicilian. With the exposed king/all my pieces on the
    Q-side I will now get walloped. After NxB Black will have many options- Qb6
    for example exploiting the a7-g1 diagonal.} (11... Nb4 12. gxf5 Nxd3+ 13. cxd3

    c-pawns. But after bxc3, exf5, white's passed pawn is strong enough for +1

    Summary: A difficult game to get a lot out of. The deciding factor was tempo,
    with h6 & Kh8 costing key moves due to the attack readied by Bxc5, Qg4! (and
    to a lesser extent Rxf5) I wasn't really sure how to conduct the attack
    after g4, and Rybka doesn't help make that strategy any clearer. I think I had
    to utilise the tempo/pawn structure advantage on f5 more quickly. If you look
    at it, white got the rook on to the g-file, and the knight to d4 for free.} 1-0

    So.. many... dollar signs!

    Yes, it converts !, !?, = etc into dollar signs.

    In Fritz there is a way around this, which I have just found again.

    Tools: Options: Clipboard and choose "Old format" instead of "PGN" under Text.

    Then !, !? etc should show as they are instead of as $X etc. But there can still be issues with things like +/=

    mm thanks for trying, I'm still getting the same thing with Rybka 3. Maybe you have to have those settings on before writing the analysis- will give it a shot next week
    Cheers
