Miscellaneous Engine Stuff

Kvetka is a convenient little program for viewing chess games from web pages like Chessgames, Chessville, Chessbase, etc. Works with all UCI engines for analyzing the game. It is intended for analyzing games only; you can’t play against it.  The program supports different fonts and encodings that are used by chess sites. It is free!


Chess War offers a small Polyglot book that was just updated earlier this month.  Also available is the author’s pgn collection containing games from 2001 to 2012 (49284 games).  The nice things about this are the standards he used to make the collection:
Minimum Elo = 2530
Only long time control games
No annotations
No computer games
No games under 20 moves

Computerschach 0ffers an opening book based on Super GM games (average 2650 Elo) formatted for Fritz/Shedder/Arena/Aquarium GUIs.  Features:
* Hand tuned and carefully optimized the strongest lines (improved for the playing styles of TOP 20 chess engines.

* The winning percentage of all inferior openings are disabled (below 50 % for White and below 40% for Black)
Unfortunately the depth is mostly only up to 8 moves with the exception of a few lines which run to 10-12 moves.  Formats for  Winboasrd, ChessPartner, ChessGUI and ChessMaster GUIs are not currently available.


  1. I downloaded Kvetka and my anti-virus program Comodo reported that there was a trojan in the exe file. This was not confirmed by Malwarebytes, Advanced System Care, and Spybot. Has anyone else found this problem?


  2. Softpedia stated they tested this product and found it free from any form of malware…BUT their test was conducted back in 2009 and they advise “this product will be retested periodically and the award may be withdrawn, so you should check back occasionally and pay attention to the date of testing shown above.”

    I downloaded it a couple of days ago but did not get around to installing it. Some quick research seems to indicate there were some “false positives” with this program but none of the posts were recent. Thanks to your warning I ran and Norton and got a suspect message, so I have removed this item just to be safe. Thanks for the heads up!!

  3. According to virustotal.com, Comodo is the only antivirus which suspects Kvetka to be malware. I sent the message to them about this issue and I guess that in the next couple of days they will rank Kvetka as clear.
