This is entirely brilliant and badass as all hell. You took bomb defusing and raised it to an art form. I'm even more convinced this should be a tournament now, with this Yes/No round being one of the challenges.
Seems like you give lots of info with tone and cadence. How about a Hector Salamanca challenge where the defuser can only communicate by ringing a bell?
I had a clutch KTaNE game where I had a maze left, had no idea, randomly guessed, and got it right and defused the bomb with .02 seconds left on the clock. Never again.
I had a similar clutch KTaNE game (One with everything, 1 expert) where I had keypad + maze left with 15 seconds. I vaguely guessed keypad which was correct, turned around the bomb when the timer was at 5 seconds, selected the maze module (1,4 to 4,2) and completely guessed Up, Up, Right, Right, Right and won with 0.30s.
