Post subject:  Go opening databases for 19x19 and 9x9
Hello.

I'm looking for some Go opening databases showing in every position the percentage of times each move is played and the percentage of times each move leads to a win for Black.

I would like a database for 19x19, and also even more importantly a database for 9x9. If you know more than one database, please show me all of them.

I would prefer that they only include games played by professionals.

Thanks in advance for your answers.

GoGoD is a downloadable collection of mostly 19x19 pro games. I use the kombilo program to pattern search it.
Online pattern search at http://ps.waltheri.net/ (I don't know what game database this uses).
gobase.org also has some pattern search and database but I've not used it for years.

There's not so many pro 9x9 games. RBerenguel here has collected of the order of hundreds I believe, far too few for any meaningful statistics.

Don't use opening something, use a full game database and database search. Database and database search / client isn't necessarily the same. GoGoD is by far the best database. You don't have to search it with kombilo, kombilo is just a convenient (free and open source) program, that does the job. Or to put it otherwise, even if you have another database search tool (w/ its own database), GoGoD might still be worth it for the improved database and other perks coming with it.

Another obvious option is smartgo (http://smartgo.com/).

Thanks for http://ps.waltheri.net/ it's exactly what I was looking for.

But I'm still looking for a 9x9 opening database. Even if it contained only a few hundred games it would still be very helpful.

There are a few dozen Ricoh Pair Go games, a handful of Cho Chikun games, a few Iyama Yuta games, a Go Seigen game, a handful of TV games, altogether I know of sixty or seventy professional 9x9 games.

I have around 400, but since I wasn't the collector I can't really pass it (I keep occasionally nagging my collector friend to let me share it, though :).) In any case, 400 is not enough for an opening database either.
