Sorry, it always takes a long time for me.

So lets look at the following example. First we have to decide,
which rules we should play. Since we need superko i propose
Tromp-Taylor.


(;GM[1]FF[3]
SZ[9]RU[Japanese]HA[0];B[ee];W[fb];B[dh];W[ga];B[ci];W[hb];B[bh];W[dg]
;B[fc];W[bg];B[hc];W[cf];B[gd];W[db];B[fh];W[ca];B[gi];W[bb];B[hh];
W[fg];B[dc];W[gf];B[cd];W[hg];B[bc];W[ch];B[gb];W[gh];B[cb];W[gc];
B[cg];W[cc];B[gg];W[ch];B[gb];W[gh]
)

After the last white move, black's mane go move taking the ko is
forbidden by superko.
we didnt say what black should do in such a case. But assume that
black is playing a program which knows nothing but mane go, then
all he can do is
pass

and then
white pass    white wins.

only if black has some intelligence then he will probably
connect the ko. Then i think black has a very promising game.

conclusion
After all with a komi of -.5 black has given himself quite an
advantage. so for the first nman moves he can play mane go.
These are maybe not the best moves, but they are good enough.
At some point he will have to stop mane go, but still he has to
play only moves which are "good enough". That way white has no
chance.
One can ask the question: does this mane go business simplify
the game for black ?
It seems to me yes. Of course it is white's duty to show that it
does not. I think this is where i have failed in my examples.
