I've seen all three of these multiple times but could never solve the third one. I believe that after many attempts, it's okay to look at the answers to tsumego to reveal to yourself what you are missing, and so I just did so. Cool problems :).

I am like DE. I can never solve the third problem. The interesting question here (though obviously irrelevant for me :) ) is whether presenting the progression of problems the way Araban did makes it harder or easier to visualize the solution to the third problem?

I presume this is the answer to the third problem?

After this, the techniques from the previous two problems apply.
This is the sort of problem I can solve if I know there is a solution, but would almost certainly miss in a real game.
