What database and database tools can I use to answer questions like the following:
What is the win/loss/draw result of games using:
I use SCID for postmortem but it's unclear if it can do these types of searches. Yes, I probably have too much time on my hands to be asking such a question.
Scid can do all that.
First,do a position search, then set up the header searh like this:
(I only get 2 results)
rooperi, I've noticed your posts on SCID and was hoping you'd respond. How about downloading a database to search, any ideas?
You can do that query in SCID. First, do a search/header on your 4 bullets in some big database. Mine, of 5M games, returns 337,000 hits. Then, move the hits to a dummy database that you set up. To do that, create a new db in file/new, then open the database switcher window and drag your filtered hits to the dummy db. Then, use the dummy db as a tree (file/open recent base as tree). Then open the clipbase to make your opening moves. Doing all that, I get: 76% were draws, of the non-draws, white won 46% of the time.
Maybe I will beat rooperi this time: database to download:
There are some options:
Icofy base: http://sourceforge.net/projects/icofybase/
Pros: Large, around 4,5 million games
Cons: Very little information, often does not show much more than player names and dates. No rating, info, noevent info etc etc...
Pros: Much more information
Cons: Smaller, around 1,5 million games
Also, it's not 1 big download, I downloaded a few dozen files I had to join to make 1 large db. (although, this might also be a plus, because files are by opening, so it's possible to work with smaller files which makes it faster)
Overall, the pgnmentor is better quality, but more work to set up
It doesn't sound like icofy base has enough information to answer questions like the one I posed. Is that correct?
Does PGMENTOR have enough information? Is that what you used in your illustration above?
pgn mentor looks like this:
And yes, i think the information is more complete
Thanks rooperi. Thanks fredm73.
May I recommend a good free online database? http://www.365chess.com
I hadn't noticed the "advanced" search options before. It might require some hand culling. I can't tell how much until I join. Ten bucks seems more than reasonable. Thanks for the suggestion.
I posted the following in another thread. I just came across a relevant book that I am enjoying: Smith, Robin (2004), Modern Chess Analysis. It's scope includes the use of databases.
It's amusing to think one of the uses of computer technology in chess is to research the use of computer technology in chess."
If anyone else is interested in such things, here's a link to a review:
