"...You have no move, Mr. Thompson. You do nothing.".
Reflecting on Nucky Thompson's compromised position in the most recent episode of Boardwalk Empire, Arnold Rothstein (played by Michael Stuhlbarg) tells the embattled Atlantic City treasurer/gangster to simply wait and plan for a time when there is a move to be made.
"I've made my living, Mr. Thompson, in large part as a gambler. Some days I make 20 bets. Some days I make none.
...There are weeks, sometimes months in fact, when I make no bets at all because there simply is no play. So I wait, plan, marshal my resources and when I finally see an opportunity and there is a bet to make, I bet it all.".
Then, having protected your capital and your wits, you may step in and seize the opportunity.
