Cutting a one-point jump  

The diagram shows what happens if White cuts the one-point jump in absence of supporting stones. (Black can of course play B4 at W5). B6 threatens a ladder at a, but Black may well play B6 differently depending on the board. In general, White will struggle to keep both W1+W3 and W5 alive.

This is why, in general[1], don't try to cut the one-point jump.

Safe one-point jump  

Here, the one-point jump is reinforced by B1, and can no longer be cut. (after the sequence a - d White cannot cut)

BQM52 has some more information about cutting the one-point jump in connection with walls.

[1] here it looks like a good idea to cut the one-point jump [ext] move 90, also [ext] move 68
