Poker is all about picking on the weak. It may be weak hands, weak players, or just weak play (Barry Shulman).
You may dislike Barry Shulman’s position because picking on the weak seems immoral, and it’s certainly not chivalrous. If it bothers you, poker may be the wrong game for you, but Barry accurately described its essential nature. It’s predatory, but so is life in general. The strong eat the weak everywhere, not just at the poker table. Winners recognize that reality, while losers deny, minimize, or ignore it.
Because they are so competitive and realistic, winners focus on power, not luck, justice, morality, personal relationships, or fairness. Poker and life are “unfair.” The best poker player doesn’t always win, nor does the one who “deserves” it for other reasons. Cancer, traffic accidents, and other tragedies happen to wonderful people, while drunken wife beaters win the lottery. That’s the way poker and life are, and you should accept and cope with that painful reality.
Winners constantly strive to increase their power, aka their edge. They want the best seat in the best game, and they wait until they have the right cards and situation. Your edge shifts constantly. You may have had an edge moments ago, but it can disappear immediately. Winners always want to know how strong their position is now.
