Have to quote this from Rounders:
“There's no other game in which fortunes can change so much from hand to hand.
A brilliant player can get a strong hand cracked, go on tilt... and lose his mind along with every single chip in front of him.
This is why the World Series of Poker
is decided over a No-Limit Hold 'Em table.
Some people, pros even, won't play No-Limit.
They can't handle the swings.
But there are others, like Doyle Brunson, who consider No-Limit the only pure game left.”
Great quote IMO.
