Formal division, 19x19.

Version: Current CVS with some extra patches. Level 14 and --large-scale.

Round 1: Huge win against Indigo. GNU got off to a good start after Indigo misplayed the lower left corner. First big mistake of GNU Go was to let white walk through at D14. GNU Go played some more weak moves but eventually managed to get a moyo in the center after passive play by black. Later GNU Go made another bad mistake by letting white walk into the moyo at J10 and was in real trouble after K5 which left a connection intransitivity problem. Fortunately Indigo never realized that it could cut. In the endgame GNU Go generally played better and when Indigo didn't defend its eyes a huge dragon suddenly died, leaving GNU Go more than 200 points ahead.
