Re: Luck is for amateurs.
In sports betting, I agree.
In poker, the professional game has become pure aggression played by 25 year old kamikazes.
If you don’t have good luck in contemporary poker, your finances won’t make it to age 26.
Luck disappears as the number of hands dealt rises. With enough hands every player will find themselves on the "lucky" side of the deck just as often as they are on the "unlucky" side. Mathematicians call it
regression to the mean. Poker players call it life and laugh at newbies on a roll that think that their particular spell of run-good is going to last. It can be a bit frustrating sitting through one of your own spells of run-bad but professionals know that over time making good decisions in tough situations, and not luck, is what matters. One of the signs of a pro at your table (and that you might want to ask for a table change) is his shrug and a grin when a two outer on the river snatches that big pot away from him and sends it to the other end of the table. A bad card on the river might look like bad luck to an amateur, but to a pro it's just a cost of doing business.
Young pros do tend to eat amateurs alive with their aggressive style of play, but that tactic becomes a money loser when they find themselves at the table with someone who knows how to counter it. Hint: it's not done with a higher level of aggression.
