rock

hi i play 1$ sng and using the preflop chart to select my hands to play .. i have added some other hands to try limp with .. but theres 2 problems 1 i usualy end up in the push/fold phase when there is about 5-7 back at the table becuse i dont get the right hands to play according to the preflop chart or i miss the flop when i do get the right hands .. and 2 i have downloadet the hm2 30 days trial to see what it can do for me .. and the hud identify me with a rock .. what can i do about this .. without too big risks ..
