The input to P is supposed to contain the physical randomness in the problem, so P(S("you're wrong")) doesn't make sense to me. The idea is that both P("green") and P("red") get run, and we can think of them as different universes in a multiverse. Actually in this case I should have wrote "def P():" since there is no random correct color.

Ok, now I understood why you wrote your program the way you did.

It's just that even in the optimal solution you still die.

By solve, I meant find a way to win. I think that after getting past different word use, we agree on the nature of the problem.
