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 youíre 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 doesnít really matter much whether itís 99 or TT-KK) But if they are the type thatíd call any bet preflop with any PP, then youíre better off seeing a cheap flop.
As is, with so little left, you donít have much wriggling room. Itís 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 heís just trying to buy the pot.
