In the USA we have a singer name Kenny Rogers and years ago he sang the song "The Gambler" . The song was about playing poker during the old west times, but he sings a key line. "Because every hands a loser and every hands a winner." It's talking about how not to just play your cards, but play your opponents at the table. You can win a hand with three A's one hand, then lose with that same hand the next one when someone MAY have a straight or doesn't have one.
Another thing I want everyone to consider; I once read a book about chess written in the 1950s by Grandmaster Fred Riefield and he said "No matter how good of a plan you may have to win a game, you must remember your opponent has a plan too!" Just because you feel you have a huge attack that might win against many players in Stratego, remember your opponent might have the ultimate plan to stop you or has a counter attack you can't defend against!
So showing what you feel is a great setup won't mean you can still win with it. It's all about how you move your units, bluffing, and creating the right plan of attack at the right time. I have a handful I setups I use as a model but, I change my units around. I've had setups that beaten a few top silver players, but then I lost to a Bronze Colonel rated player the next game with it. You just never know what to expect with this game, and that is the beauty of it all.
