Main line

The 2-2 point is again the solution. As in problem 4, a and b, and c and d, are miai for life.

Wrong

It is very tempting to block at W1 here, because that seems to make more points while living.



However, Black plays at the vital point B2; and after White's strongest resistance with W3, B4 makes miai of a and b to kill White.


The first problems in these series mainly serve to explore the properties of 1-2 and 2-2 points.

What about the 1-2?

Is there something wrong with W1? kerrytyk



ChrisSchack: I think B2 then either connects out or transposes into the previous failure.
