Fox and the Farmer - Chuck Thompson
hmmm 3.5 BB minimum. When you hit 3.5BB, you MUST make a play.
Fox and the Farmer - Chuck Thompson: "Second, look at your own chips. For you to be a fox, you should not let your chips fall below three and a half big bets, the amount of chips necessary to raise before the flop and still have full compliment of bets for the remaining streets. It's not that you intend to use all these chips. Your hope is that nobody calls. But you need to have the chips so that your would-be opponent knows he can't run you down cheaply. In other words, if you have just three and one half bets, you should be willing to make your steal-raise with a weaker hand, simply because you must take the initiative in order to keep your chips up and survive another round of blinds."
