A six-shooter is loaded with three cartridges
in consecutive chambers, before two persons start to play "Russian Roulette" until one is dead.
If the cylinder isn't spun after each attempt, would you rather be the first shooter, or the second?
What would be your answer if there are only TWO cartridges, of course in consecutive chambers?
I read the official solution. Unfortunately, I still didn't get it.
Then I read the comments. np_rt's answer cleared it right up for me. I didn't take into account the significance of the order of the bullets in the chambers.
Boy am I glad I went second despite my faulty reasoning!
