Poker In your opinion is this ( link) pre flop hands to play in specific positions, right...?

Btw so far my pre flip play is , UTG ( based on 9 players including me...) I raise with aq+ and limp all 22-77 pair and limp with suited connecters from 4-6 being my bottom suited connecters hands range... ( I don't limp with a2suited or a3 unless I have at least 200 big blinds since these hands r very often dominated and really only profitable when you hit a flush and since there r minimum straight possibilities I font treat this had as a normal, suited connecters .. UTG +1 I raise small pocket pairs 22-77 UNLESS UTG guy limps ( again if I am big stacked I mix it up and might raise when he limps..) and same goes with suited connecters and I also raise aq+. Mid position I raise 10joff plus with no limpers and same story with the small pocket pairs and suited connecters ( when I say 10j + I mean 10 j, 10q, jq, jk, qk ( but not a2-a7 as these hands r often dominated in this position ). Late I raise k8 + and same story with small pocket pair n suited connecters. Out of position I raise q8 + ( obv my raise size will have to do with my position..) and if I'm out of position against more players than I'm in position against I wud limp small pairs n suited connecters and vise versa ( vies versa - don't know how to spell that..) so what do you guys think... Btw I'm ALWAYS raising 88+
