Chess Game Database Download

Next you'll need an analysis engine. Houdini 1.5a has long been the strongest free chess engine available, but I've recently read that the newest version of Stockfish is stronger (though the CCRL still puts Houdini 1.5a ahead). Since SCID supports several analysis engines you can install both if you like.

The ICOPY database includes a whopping 4.6 million games, with a 2/16/2013 update available. There's obviously going to be a lot of overlap between these, but I don't know yet if ICOPY includes all the games in Millionbase.

For those who have been primarily using lichess/chess.com, and want to dig into chess a bit further, having a database can be extremely useful. It is to me, at least. And in 2018, your path to a high quality set up is actually pretty easy and relatively inexpensive (and potentially free).

SCID or SCIDvPC. This is an open source chess database, available for free. From what I understand, SCIDvPC and SCIDvMac are both later versions of SCID with more features. SCIDvMac is the one I've tried.

EDIT: u/PossibleOatmeal correctly pointed out that SCIDvPC/Mac is a fork of SCID, but that they serve different purposes. SCID is more focused on chess database features, and SCIDvPC/Mac is focused more on UI and engine v. engine matches. Both free, so no reason not to try out both and see if they work for you.

Note: This will work on the mac under an emulator, and there are lots of ways to emulate a PC on a Mac. VMWare, Parallels, VirtualBox, etc. I like VMWare myself, but personally, didn't want to have to load it up every time I wanted to use my chess database.

3) Hiarcs Chess Explorer - this is a pretty under-rated chess database imho. I chose this one because I'm on a Mac and it's the only commercial database available for Mac that runs natively. But that said, it is quite good, has a lot of great features, and I like it a lot. Base version is $50. The "Deep" version with endgame tables and multi-processor support is $100, and you can also subscribe to their professional tournament opening book (which I have tried, and I do like).

If you download the 3 collections I mentioned, you now have millions of games at your disposal. Chessbase has their Megabase product which only works with Chessbase and has a lot more games, but I honestly haven't yet felt like I'm missing anything critical from the free set that I have. For what I'm using it for, the free ones have been more than enough so far. If anyone has used both Megabase and the free databases, feel free to comment on the differences in the comments.

But you will get a complete analysis out of the engines using any of these systems. Also, adding comments, multiple lines, exploring openings, etc is standard functionality for all of these as well. I think anyone who is striving to be a serious chess student should have at least one of these set ups.

The biggest online chess database with over 9 million games is now available on Chessify for free. We've collected professional chess games from the late 1500s to the most recent tournaments of 2022 to present you with the biggest chess database online.

To use a similar database on your chess GUI program, you would've needed to spend around $200, while at Chessify, you only need to create a free account. We are going to update our database weekly, so you will always have access to the latest games.

The database feature is still in the Beta development phase and will be improved throughout the month. We appreciate your patience and support. If you detect any kind of problems, please report them to info@chessify.me and help us improve the database faster.

I am using SCID as an alternative to Chessbase and have been using it for analysis and doing some prep. I have Cassiabase's masters database, which is good for knowing theory and seeing what high level players do, but I'm about 1000 elo points (USCF) below these masters, and I want to get a sense of common choices made by players in my rating range for certain openings. Is there a database online that has games from amateur/club level players I could load in SCID? Thanks!

With our Opening Explorer you can browse our entire chess database move by move obtaining statistics about the results of each possible continuation.

The Opening Explorer is a great tool if you want to study chess openings.

Hi, I've downloaded a PGN chess database of around 1.2 million games from CCRL (chess engine games), with an uncompressed size of 1.4 GB. For some reason I can't seem to able to import the whole database to SCID. It reads the PGN file just fine but only imports around 262k games with a message saying the maximum number of games for that type of database had been reached.

Anyone has any idea what it means by 'this type of database' and how to resolve this? As far as I can tell it's just a regular PGN database, I was able to open it without any issue in Shredder 13. thanks

A series of recent works studying a database of chronologically sorted chess games-containing 1.4 million games played by humans between 1998 and 2007- have shown that the popularity distribution of chess game-lines follows a Zipf's law, and that time series inferred from the sequences of those game-lines exhibit long-range memory effects. The presence of Zipf's law together with long-range memory effects was observed in several systems, however, the simultaneous emergence of these two phenomena were always studied separately up to now. In this work, by making use of a variant of the Yule-Simon preferential growth model, introduced by Cattuto et al., we provide an explanation for the simultaneous emergence of Zipf's law and long-range correlations memory effects in a chess database. We find that Cattuto's Model (CM) is able to reproduce both, Zipf's law and the long-range correlations, including size-dependent scaling of the Hurst exponent for the corresponding time series. CM allows an explanation for the simultaneous emergence of these two phenomena via a preferential growth dynamics, including a memory kernel, in the popularity distribution of chess game-lines. This mechanism results in an aging process in the chess game-line choice as the database grows. Moreover, we find burstiness in the activity of subsets of the most active players, although the aggregated activity of the pool of players displays inter-event times without burstiness. We show that CM is not able to produce time series with bursty behavior providing evidence that burstiness is not required for the explanation of the long-range correlation effects in the chess database. Our results provide further evidence favoring the hypothesis that long-range correlations effects are a consequence of the aging of game-lines and not burstiness, and shed light on the mechanism that operates in the simultaneous emergence of Zipf's law and long-range correlations in a community of chess players.

I frequently see advice about how to learn chess that include links to databases, or how to set them up, or a question here about Analysis where the accepted answer says to just add some stuff to your database.

A chess database is basically a collection of chess games, i.e. a collection of moves with metadata such as player names, date, Elo rating of players, place, opening name ... It can also include comments/annotations for some or all games.

There are various websites such as lichess, chesstempo, 365chess where you can access chess databases for free. Alternatively you can download database files from the internet or buy them from somewhere like ChessBase and access them on your computer. For this you need a program/application such as Scid (free) or ChessBase (not free) which can read the database files and allows you to play through the games and do all kinds of searches/manipulations to the database files.

A chess database is a file or set of files along with a computer program which allows you to store chess games in a way that allows you to easily search through them. The associated computer program should also allow you to easily hook up a chess engine to help you analyse the games.

Every time you play a game where you recorded the moves when you get back home open the database and enter your game in the database. Then you can go through it, first using your own brain trying to work out which were the good moves and bad moves and why and second with a chess engine hooked up to see where the engine thinks good moves and bad moves were played.

Then a few weeks or months or years later when you are drawn to play somebody you played before you can go back to your database, look up the game, work through it again and see what you have to do to get a better result this time.

Note that you don't need to pay money to get your hands on a chess database. There are lots of free programs out there which will do the job for you and free sources of games if you want to download other people's games. 2351a5e196
