We should also mention Waltheri, which can be browsed using pattern matching, or conventionally by date or players. There are about 70.000 games in that database, mostly from the last couple of decades.
Maybe Iâm using it wrong but I find Waltheri severely lacking in what you can search for before it starts giving you 'no results. Like variations starting from corners or something. Either way, I jsut find that using my personal colelction and Drago gets me more results most of the time.
To answer your question, no - I donât think thereâs any way to download a bunch of games as an archive from gokifu.
I guess my next question is - WHY do you need to download a bunch of SGF files as an archive? If itâs for training a neural network, then sure - I understand, youâd want thousands on hand.
But, if youâre just reviewing pro games for your own learning - why not just view them for free online? Search the player you want to study, then look up interesting games and go move-by-move. I guess thatâs how I got used to doing it.
Aside from that, is there a particular reason youâd need to download lots of SGFs to your own hard drive?
Side note - if youâre in it for the expert commentary and tsumego, then I totally understand plonking down money. But if youâre just looking to review pro games, theyâre out there for the takingâŚ
All of the games have simple, fixed links, so you could pretty easily write a script to crawl through all of their games pages and download everything. Itâll just be the âhrefâ attribute on the second link element in all of the .game_type divs. Thereâs about 40k pro games and 65k kgs games (which all seem to have at least one dan-ranked player), so thatâll net you over 100k games for $0 + maybe an hour to figure out how to code things + however long it takes to download everythingâŚ
the reason is sometimes its more comfortable if I can access it offline using SGF editor.
especially when traveling, some places in my country have poor internet connection.
anyway, I subscribed [redacted] and got 30,000 tsumego problems including Cho Chikun Encyclopedia, Guanzi Pu and other collection. cool!
