Shane's Chess Information Database (Scid) is a popular free UNIX, Windows, Linux, and Mac application for viewing and maintaining huge databases of chess games. It is written in TCL/TK and C++. Scid has undergone several stages of development. Firstly by Shane Hudson, and then Pascal Georges. Scid supports portable game notation and its own database format. It can interface with Winboard engines (such as Crafty and GNU Chess), and UCI engines (such as Fruit, Rybka, Stockfish and Shredder) to perform position analysis or play computer-human games. Scid can be used as a graphical interface to connect to and play games on the Free Internet Chess Server, FICS. It can use up to five piece endgame tablebases, includes a move tree with statistics, and display photographs and information of players in the database. Scid can classify games using the standard ECO code, as well as its own extensions to the ECO system. One can search for specific endings, such as pawn vs. rook or rook vs. queen. Scid's search allows filtering by player, color, year, result, and ECO code. Shane's Chess Information Database (Scid) is a popular free UNIX, Windows, Linux, and Mac application for viewing and maintaining huge databases of chess games. It is written in TCL/TK and C++. Scid has undergone several stages of development. Firstly by Shane Hudson, and then Pascal Georges. Active development is mostly with the fork - Scid vs. PC. Shane Hudson is the original author of Scid. He worked on it from 1999 to 2003 and the program is named after him (Shane's Chess Information Database). A lot of code he wrote are still in use (especially c code) and if you are curious or nostalgic have a look at his last readme. The people who helped him are thanked here. Shane's code focused on speed and most notably implemented two very clever ideas: •store chess moves using only one byte. Representing 64 squares requires 6-bits(2^6 = 64), so in order to store a move (from square to square) you need 6+6=12-bits. Add a least 1-bit for promotions and you are at 13-bits. Chess players usually like puzzles: i let you the fun of discovering how to store chess moves using only 8-bits. •when searching games for a specific position, search instead for the games that did not reached that position. This apparently strange idea is the reason why Scid's tree search is so fast. Modern computers have now a lot of memory and speed, so saving bits is a little out of fashion (and there are obviously some drawbacks: the 1-byte format makes chess960 and illegal moves difficult to store, and the tree search do not go into variations), but many other projects was created from his codebase and nowadays, PGN format apart, scid is the most known free (GPL) chess database format. Pascal Georges Pascal Georges worked on Scid from December 2006 to January 2010. He added many features: •Interface for UCI chess engines •Docking mode •FICS •Training features •support for Novag Citrine He also ported Scid to Pocket PC. The Scid Project TODO: Franz Nagl added new spelling and rating files on April 2007 Alexander Wagner June 2008 (scid-3.6.24)

Here is a resurrected game, that I played in May 2010 Hamilton Quads. From time to time, I do look at chess and only play online with the Internet Chess Club. I only play standard long games on the ICC online chess club under my user name " diamondback". Its been two long years since I have played over the board chess and I am contemplating stopping by Ewing Chess Club, New Jersey to play in their quads very soon. Here is the crosstable of April 2013 Quads at Ewing Chess Club and one can see many names on the Ewing crosstable that also frequent the Hamilton Chess Club Quads. One name that appears on serveral occassions at Ewing CC Quads is Atomic Patzer. Maybe Atomic Patzer will post some games or pictures of Ewing Quads on his chess blog soon. Hopefully, some of the regular heavy hitter New Jersey masters who show up religiously at Hamilton Chess Club Quads will play in the Ewing CC Quads sometime. Directions to Ewing Chess Club Quads in New Jersey.
