Dan Shak is playing cards at Table 3, but he's equally involved in another risky financial endeavor on the rail. He recently came over near our table to retrieve his now-charged laptop, and he set it up on a food service table near his seat. Between hands, Shak hops up from his chair, runs over to his computer, and dabbles in a little stock trading. With one eye on the poker table, he jumps back into his seat just as the dealer is passing out the cards for the next hand. Now that's multi-tasking.
