Down to a bit over 10BBs, I would have seriously considered shoving preflop here if I had a tight image up till then. If the limpers are tight as you say, good chance they all fold and you’re not dominated by anything that calls unless maybe 99 and A9, AT, possibly AJ. (Assuming better hands than that would have raised pre, and it doesn’t really matter much whether it’s 99 or TT-KK) But if they are the type that’d call any bet preflop with any PP, then you’re better off seeing a cheap flop.
As is, with so little left, you don’t have much wriggling room. It’s either all in or fold beyond that. If the chip leader is late to act and puts in a raise then I would just shove here and HOPE that he’s just trying to buy the pot.
