I will make a permanent link of this post in my sidebar.
Do you know more abbreviations we frequently use?


  1. I was what all of those things meant. Still wondering what "circles" are. The real abbreviation should read:

    GOD - Michael De la Maza


  2. Over the board. Maybe even 45/45 for the teamchess League.

  3. Wow, I've become an abbreviation! My family will be so proud.

  4. 45/45 is 45 moves in 45 minutes. g/30 is game in 30 minutes. g/5/5 is game in 5 minutes with a 5 second per move increment.

  5. OCL - Online Chess League (sponsored by Chessville)

    BDK- Blue Devil Knight

  6. I've seen this one occasionally:

    CTA - CT-Art Tactics Software

  7. ...and I think STC means "Slow Time Controls". They're active on FICS, ICC, and USCL.

  8. CD, if I record BDK then I must do so with all the Knights. Since the abbreviations of the knights give seldom a problem I don't want to mix the list with them.

  9. This is incorrect
    > 45/45 is 45 moves in 45 minutes.

    1. G45 - means 45 minutes for the whole game.

    2. X/Y means X-minutes + Y-increment per move. So 45/45 means 45 minutes plus 45 seconds increments per move. Roughly equivalent to G60 (in my experience)

  10. And how does one say 40 moves in 2 hours plus 1 hour for the rest of the game?

  11. Aye, like Neza said - usually refers to games played in "Team 45 45 League" on FICS/ICC at "". I don't know the FICS link as they seem to have become independent.

  12. Tempo - 40/2, SD/1 which translates 40 moves in 2 hours followed by a 1-hour sudden death period.

  13. 45/45 in a Chess Life tournament listing would mean 45 moves in 45 minutes. At least to the best of my recollection. It may have a different meaning online. And yes 45/45 would normal be followed by SD/30. Or 45 Moves in 45 Minutes, Sudden Death 30 minutes. Admittedly an odd time control but I always read 45/45 as 45 moves in 45 minutes.

  14. Thx guys, I believe the time controls have a consistent format now (pfeww)

  15. There are a lot of opening abbreviations, too.

    KIA - King's Indian Attack
    KID - King's Indian Defense
    QGD - Queen's Gambit Declined
    QGA - Queen's Gambit Accepted
    C-K - Caro-Kann

  16. SCID
    NIC: New In Chess
    NM: National Master
    SS: Swiss System pairings
    RR: Round Robin pairings
    QC: Quick Chess
    TD: tournament director

  17. Tempo,
    There is an even better link for you to use for the acronym, ECO.

    The link you are currently presenting for the acronym, ECO, is okay. But the annoying thing about that chessopolis web page is that the moves of each ECO code are not numbered. I should send an email to the webmaster of chessopolis; but I'm probably going to be too lazy by the time I finish making this post.

    Anyway, a better link for the acronym, ECO, is to link to the publisher of ECO. The publisher's web page is a link that people should make a point of sharing with others. What people fail to realize is that only by making reference to the publisher of ECO can we find the actual definitions of the ECO codes. Somebody has to set the standard or there is no uniformity. In a world where people do not appreciate the value of setting standards, we can better serve people by pointing them in the right direction when they come to us and ask for directions.
