Don't play for traps!

Trappy play and hoping your opponent doesn't see it is a very self defeating method of conducting the game. Better instead, is to conduct your army in such a way that every part of it is important and you never let any of it go without a good reason. Hoping your opponent doesn't see a trap is not such a reason and players that rely on that will find soon that indeed opponents do see and guard against "traps". Be careful that you don't trap yourself!
