Rn misses intentional Ko(覇) weakness

[crayzok]

After K6 move of black, White should put the M6 move to avoid Ko(覇).
But Rn didn't.

Now it is unavoidable that White meet Ko(覇). White has to put blue dot.

White cannot connect 8stones in the center by a L7 move.

If white put a L7, group of white are all dead.

Not only RN, Zen and Leela cannot catch it too.

I think that is common problem of MonteCarlo because I have seen too much of those bugs since Zen4.
