I used to push Ace rag as a semi-shortstack in early position ...

With 6-8BB and Ace rag I used to push an unraised pot regardless of position. Now even with that short stack I'm looking for A8s or better to push UTG or UTG+1 and instead look for blind v. blind or late position opportunities. I don't have the calculations but experience has shown that picking up chips in late position is preferable to pushing a possibly dominated hand.
