I have added two restrictions to this pattern by the following patch.

Pattern D124

Thus there must be an own stone left or right to * and there must be no own 
stone above *. Now there are less regression breakage. For move 104 of Dan's 
game, it played P9.

owl:80 pass
lazarus:16 pass
nngs3:1000 pass
handtalk:10 fail  Correct 'E9|F8', got 'C11'
arend2:50 fail Correct 'S14', got 'T13'

The failed cases seem to not only related to owl analysis and I have 
difficult to understand the gnugo's decisions.
