Decisions decisions. Don't mind leading here. Seems like leading < 1/2 pot is decent, dependant on stack %'s, ICM considerations, blah blah blah. Bet/calling for stacks is bad, with stack sizes as they are you have bad equity vs villains value-shove range and this is never really going to be a air-ball bluff-shove spot for anyone playing the 300. Best case you are against AcXc, worst case AJ, KJ, sets and AA-QQ.
So for me it's:
A) bet small enough to allow for folds to re-raises/ships
or
B) check-call to re-evaluate turn.
[ or C) get it in, find out you're miles behind and do some wiiii binking and get there ]
If stacks have limped into the pot small enough that leading here gives you no fold-equity to a shove, option B. If people are deep enough I would be going with A as I would want to be keeping a slightly balanced range between leading draws and made hands here (although balancing ranges is barely worthwhile in the deepstack). If you spot Alex or Mitch in a hole in a 1/2 game, option C is clearly +EV, regardless of getting there or not.
