Jeopardy Contestant Holzhauer Keeps Rolling Along

Jeopardy, one of the oldest game shows running is seeing something it has never seen before.  In 15 games James Holzhauer has accumulated over 1,100,000 dollars becoming the game's second million dollar winner in it's history.
Ken Jennings, the game's previous million dollar winner, took over 70 games to amass his fortune.
Holzhauer's system is to begin by picking the bottom boxes (harder questions worth more money) of the Jeopardy board, amassing more money and beginning getting a huge lead early, seemingly to unnerve his opponents.
It would come as no surprise that Holzhauer's profession is listed as a sports gambler.    He lives in Las Vegas.
Making a living as a sports gambler seems unlikely to most people.  It you ever watched the movie "Rain Man", Nevada does not seem to take kindly to people it thinks have learned to beat the system.
