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?

That's it, I'm memorizing the entire Gokyo Shumyo! :rambo:

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.
