Formal division

Size: 13x13.

Time: 18 min

Name: GNU

Version: Current CVS with some extra patches. Level 15.

Round 1: Some strange moves but in the end a huge win against firstgo.

Round 2: GNU failed to defend a big dragon on the left side but got enough compensation elsewhere when viking5 spent too many moves killing it. Win by resignation.

Round 3: First GNU barely found its way to invade a high right side but when things settled the game was close. CrazyStone managed to capture a three stone tail of a dragon but GNU instead destroyed territory on the top and came out far ahead. Then disaster struck and the upper left corner was cut off and killed, losing the lead. In the endgame CrazyStone made some small mistakes and GNU managed to win by 0.5.

Round 4: A reasonably good game but viking5 blundered away some stones on the right and missed a chance to live in the lower left corner when GNU misplayed. Win by resignation.

Round 5: CrazyStone again opened high, this time on the left side. GNU invaded the upper left corner right away but failed to reinforce it in time when it became threatened. On the top a terribly complicated, if not confused, fight broke out and eventually settled with a clear partitioning of the board. Then GNU was allowed to walk along the bottom and even take over the lower left corner while white spent moves to bring the dead stones in the upper right back to life. Eventually that succeeded when GNU misread the ensuing semeai but in the end black ended up with all the board except for the stones lost in the semeai, winning by 33.5.

Round 6: Weird opening where neither player had any interest in the corners after the first one. White managed early to split itself into four weak groups. While GNU didn't play convincingly all the time it had no problems to sweep the board and win over firstgo by 161.5.

GNU won with a perfect score
