Re: computer-go: Recorded games with dead stones marked

[Erik van der Werf <E.vanderWerf@xxxxxxxxxxxxx>]

Hi Peter,

IGS games that are finished and scored contain territory information. In 
the sgf's it is encoded as TB[xy][xy]... for the black points and 
TW[xy][xy]... for the white points. Unfortunately it seems quite 
difficult to acquire (large amounts of) IGS games without getting into 
trouble with the IGS admin(s).

My best solution so far was to use NNGS game records, which are 
available on-line, and score them by a program like gnugo. If you want 
very good data you will need to do some manual inspection also, but in 
general gnugo should provide quite reasonable data. The command I used 
for getting the scoring data was something like:

gnugo --score aftermath --capture-all-dead --chinese --infile $SGFFILE 
-o $SCOREDSGFFILE

However, recently Inge Wallin suggested that it might be better to get 
the information using the go text protocol. (The above occasionally 
seems to trigger some rare bugs in gnugo 3.2.)

A while ago William Shubert offered to share the KGS game records (in an 
email to rgg.). Since I was again looking for more game records I 
recently send him an email. Unfortunately I've not yet received an 
answer (maybe he's on holiday?), but when I know more I can let you know 
if you want.

These were my clues ;-)
Erik


PS Let me know if you manage to get large amounts of IGS games.
