Did I win?

Today may (or may not) have been a big milestone in my Go play. I think I won a game against Go169 on my Palm, but I'm a little unsure. This would be the first time I've beaten... anything. Yes, I am aware of the lamentable state of Go AI. I am just that bad.


No handicap, 13 x 13.
I made a lot of mistakes, passed and then had White move, and even used the undo button twice.
*guilty*

The reason I'm unsure if I won or not is down to scoring. With the dead groups killed, I have a territory of 48, less 16 stones captured by team White for 32. White has 30, less 5 stones I captured for 25. The difference is 7 moku minus 6.5 komi. I win by half a point.

Go169 thinks I win by 18.5 points, for reasons known only to it and the eldritch horrors of the night.

Sente Goban seems to think 12.5, when I backfill the captures onto the board, mark dead groups and then order a count.

What's going on!!

edit: Thanks to WzDD and Hiroki Mori who pointed out I was forgetting to fill territory with the stones from the killed groups. After doing that and resquaring the board, I get Black 48 - 16 - 3 = 29 against White 30 - 5 - 14 + 6.5 = 17.5 for an 11.5 moku win.
