The limit of the new version of SCID will be 4 billion games, 256 million unique names, and 64TB.
However even opening one of the monthly lichess database uses more than 16GB of RAM, so the power of the computer will be the real limit.

Re: Survey: tools for database analysis

Just saw a video where Martin If it's interesting please post the link :) says database is an implementation detail. That's actually the meaning of my question. The example of data analysis I made, count the number of players based on their average ELO, was intentionally trivial. However, many peop...

Thanks, but I think that CQL is not able to produce statistics.

Survey: tools for database analysis

I would like to know about the available tools to extract custom statistics from a chess database. Let me make an example with the latest lichess database (12 million games, 26GB unzipped): https://database.lichess.org/ and let's say that I want to make a D3.js graph: https://github.com/d3/d3/wiki/G...

Re: Most common destination squares from 1M chess games

So I wrote a little script to count the most common destination squares from every moves and here's the result: There is a tool in SCID that does that and it's called "piece tracker" (but there was a bug in 4.6.4 when selecting multiple pieces, so it would be better to compile the git version).

Re: Elements of the ULTIMATE Chess GUI?

The sequence > xboard > protover 2 < unknown command: xboard ? => UCI < feature ... ? => WB v2 < Error (unknown command); protover ? => WB v1 wait 1 sec > uci < uciok ? => UCI wait 1 sec WB v1 seems a reasonably reliable protocol determination, and could be made default. Please don't. We are at the...

Re: Elements of the ULTIMATE Chess GUI?

Not wanting to learn all that should not really conflict with the presence of an extra facility for people that do want to learn. Good (well, you wrote a lot of posts repeating the same things without even bothering to try to understand). Now that you are almost there, one last effort: try to focus...
