When playing poker at the highest levels it is important to bring all of your weapons to bear, but when you start running out of chips you get knocked down to eventually one weapon - the all in move.
There are those people who are (supposedly) blessed with the ability to see into the future. That Nostradamus fellow is the most famous of these prophets or psychics or whatever, but history is filled with those who would claim they had the ability to see through the veil of time. When you play poker, you often find yourself wishing you had such a power. The ability to see into the future would practically guarantee your success in any game at any table.
