I rarely see players follow the first-in hand range guide you provide in 1/2 cash or in tournaments. This makes my guessing at their hand ranges pre-flop almost impossible. Instead they will play any two cards that seem promising to them in any position. Since the first-in hand range guide is one of the main tenets of your overall strategy, most players' lack of applying it, most of the time, makes it difficult for me to know what to do in live play.
