When i start the game, i forgot the money, i`ve bet. If i win - it will be nice bonus for fun, if i loose - it will not become a problem. And when someone decides to use poker for moneymaking - he must remember that he can be the best player in the world, but without good cards even he can loose. This is not chess game, there is some moments, when you need just luck.
In poker, there are many crucial moments... so I agree that some hands are all about luck, especially when you go all-in before flop! Even two aces can fall easily, and that happens often, I can't count how many all-ins I have lost with two aces in my hand against lower pair, even vs low cards!
What makes a good poker player is the ability to play with good and bad cards! To be patient, and to wait for better cards... to make a bold move in some moments and bluff, the only way to keep your bankroll from melting down!
