You mentioned that maybe you'd just call the flop and could muck on the turn if a scare card (presumably a spade/low spade), came. I don't see this as an option. You might creep into the money with your crippled stack, maybe not, but remember you have ten outs to beat a flush on the turn and your pot odds would be such that it'd be crazy to muck just for the sake of finishing barely in the money when you could win a big pot and be in the running for a real payday.

This "highish" flop seems like a place to make a stand with bottom set to me. I would expect in desperate times to see the early position players (the blinds here) to make moves with any high type hand or draw, hoping that others yet to act would be going low and might muck. I don't think I am being results oriented with this, that is, I see they both were drawing, but I don't think this is as much the exception as it might seem.
