so true, so true... but until one develops the adequate postflop skills and the knowledge of diferrent poker concepts, the skill to read the table and to asign accurate ranges and all other skills needed to play 56s in UTG and/ or call gapped SC in MP vs EP opening, the math for preflop strategy is easy ( as i can see it ):

the more people are behind you that will act ,the greater chances they have a better hand then you and the greater chances you will get a 3bet and the greater chances are you will see a flop OOP that many times you will mis. so w/o the skills rpm said and w/o experience and a good postflop skill the more chances you have to spew.thats why preflop strategy for begginers says play 77+, AQ+ in EP ,add some more in MP and play a lot more in LP.
