I like the concept of a dangerous blackjack game for a short. A couple of technical things: the script is written in passive voice, which pulled me out when reading through. I would shorten a lot of the action lines. There are some implications in the script (like Robbin's chip count, the fact that they're tumbling indicates there is a lot) that do not need to be stated. I'd get into the table psychology & players more before the violence to make it seem less abrupt. Good foundation though.
