Opening----I7-G9 (English version)
situation：black win
j10 i7 g9
This move was proposed by Professor Wu, since he wanted to know whether there are OK moves outside 5x5.
Chen Cheng-Kuo (CCK) solved this one. And this has been verified by NCTU6.
Wrong Move：j10 i7 g9 j11 k10
This is the first feeling off head. But, unfortunately, both W pieces in the next move are at the perfect position.
Defense by W：j10 i7 g9 j11 k10 j12 L10
Both W pieces are at the perfect positions. W has four Live2.
The subsequent moves are still very complicated. In any case, we have not found winning moves for B or W.
Variation 1：
Actually,B5 has several variations. This could be the one that most like to choose.
The subsequent moves are still quite complicated. A careless move in each side will soon result in losing. B11 is the only defense.
Variation 2：
This B5 is not better than the previous one.
At this point, W coulde have a little more advantage over B. However, it seems still hard to verify whether W is winning.
Correct Move：j10 i7 g9 j12 l10
This is the correct move. W makes no more Live2.
The subsequent variations in Variation 3 and Variation 4 are verified as B winning. If W attacks with Live4, these moves are all verified.
Variation 3：black win
Variation 4：black win
