PART 1 • Basic game searches Searches for games of a specific opening are also regularly performed by most chess players (mainly because players tend to spend far too much time studying the opening, but that was mentioned earlier). Most chess playing programs allow you to search for openings by ECO code (described in Chapter Nine, along with tips for finding codes you don't already know). You'll just type the ECO code in a box, click “Search”, and the program will pull up all of the database games which are identified as falling under that ECO classification. Some programs will offer two boxes for opening searches, which allows for a search which covers a range of consecutive codes. For example, the Petroff Defense (1.e4 e5 2.Nf3 Nf6) falls under two separate ECO codes, C42 and C43. You would type “C42” in the first box and “C43” into the second, then do the search and see a list of all of the Petroff Defense games from the database. As noted, different chess playing programs offer different database search tools, some more elaborate than others. In addition to player and opening searches, most also allow searches by year, result, and player rating. Others add factors such as length of game, tournament name or geographic location of the event, and sometimes even specific board positions. The more comprehensive (and much more expensive) database programs provide an even bigger variety of search terms, including maneuvers (specific piece moves) and material balances (two Rooks and three pawns vs. a Queen and one pawn, for example). COMBINING SEARCH TERMS You can combine search terms when looking for games in a database. For example, you can type on player's name into the “White” box, another player's name into the “Black” field, and the program will show all of the games in which those two players faced each other. You can specify the colors they played, as well, so you can get all of the games in which Player A had the White pieces while Player B played Black. Another commonly searched combination is “player and opening”. For example, Garry Kasparov was well known for playing the King's Indian Defense at one time, so you could search for his name under “Black” and the ECO code range from “E60” to “E99” to see all of his games in which he played the Black side of the K.I.D. The more search terms a program offers, the more specific your searches can be. But there are a couple of pitfalls you should be aware (or just beware) of... 122 chessking.com
