I think position and learning it and realizing how to actually play make a bluff a move etc.. is the most non used thing in poker.
Earlier tonight someone in first position in front of blinds no name all in with pocket sevens meaning 8 to act later. To me I would NEVER DO THAT.
In that position with aa i minor raise kk same sometimes queens and jacks but otherwise im limping and waiting to see a flop. I am always amazed all ins with low pockets to me is just stupid you want to catch sets and have someone catch their ace and get paid not lose entire stack or a tournament just saying.
You need table image in order to use position so sharing a hott streak or some quality hands and moves is smart to me at times.
So learn position change betting patterns use the tools you have. Got to mix it up though or otherwise is not a tool.
