Black to connect

ChrisSchack I believe Black can connect by playing at a or c in this situation, as follows (this is the difficult situation):



[Diagram]
Black connects

Note that playing 4 at f leads to the same situation


[Diagram]
Black to connect continued - 4, 6 at marked stones

Now if White a Black c, if White b Black d. Each White group is contained and will be captured, and Black connects.

unkx80: A hint: Must White 1 capture the marked Black stone? Can White 1 be played elsewhere?

ChrisSchack Oops, you're right, White 1 at 2, Black either connects the marked stone and loses the stone at a, or doesn't and loses the marked stone, and either one blocks connection. The whole a line fails, then, I think...

If White's stubborn

Confused: Not capturing may be better for White.


[Diagram]
Black to connect continued variation - 3 at marked stone

White's blocking group could try to run, but the Black position is really too close and strong, as is the edge...

Black to connect variations

c and f are miai, if d or e then b, and any other points should be simple.

Black to connect

Dieter: So far for a and c. With this in mind, e will prove not too difficult. And if b is simple to you, you are passing the stage of beginner.

ChrisSchack Same thing as in games, I'm missing the obvious. In this case, that I had NOT dealt with b as I meant to try...



[Diagram]
Trying the middle

Confused: That doesn't work too well for Black either. Playing 3 at a doesn't connect the groups either, although Black may have a better chance of living with both groups.

Not really better for Black
