Gerard, please explain your shorthand (once more)! There can sometimes be shorthands, e.g., if the maximum value of an endgame region is too small so playing in another region must be more valuable. - Have you read my proofs now and formed an opinion?

Robert, the problem is that I do not know what do you suggest in order to find what white has to play in the example above.
It suspect I misunderstood completly your process to find here the white move and I do not want to disagree on something I am not sure.
Please explain your process on this example.
Be sure I will forget my proposal if your process is efficient in real play. So let's begin by understanding your approach.
Concerning double sente and your proof I have no more problem:
With you defintion "double sente" do not exist. With my defintion double sente exist but they are only a particular case of gote without any interest for theory. At least it is clear.
BTW I tried to undestand your proof but, because I basically agree with you if you take your defintion, and because your notation is quite hard to masterise, I gave up. Anyway I am pretty sure it is correct in your context.
