Here's a interesting video lecture where cutting the one point jump was good:

Invade everywhere, then live in the center

Here's Lee Changho wedging a one-point jump, I won't say when so as to not spoil the surprise if you want to find it yourself (with the considerable hint of being on the look out for one point jumps to wedge!).



P.S. Also keep going to the end. Lee doesn't always win with boring endgame, he finds a really sharp sequence with a lovely nose tesuji to bring about the resignation.

If you want a shape that cannot be cut this one works better.

I think people do tend to take the one point as connected for granted, but I also tend to over cut that shape. Some people also like to peep too much.

I think you are missing the general idea here is splitting white and attacking is god of black, small details like A and B ignored because blacks general position is better and so he should come out ahead regardless
