I don't actually know. I had a few strong setups that I rotated through, but even after I started explaining my strategy after every game, and even giving hints during the game, my best childhood friend would still lose so much it wasn't fun for either of us so we stopped playing. He's smart, and was fine at most games, but no match in Stratego. I guess I'm just good enough at the various aspects of the game, memory, bluffing, planning, that it added up to being a pretty strong player even without much in the way of study or practice. I'm sure I'd crumble against an actual serious player, and would have back then, too, it was just that I wasn't around anyone else who liked the game enough to become good at it.
