Either you're lucky or your not. Now it helps to know how to play the game, with correct basic strategy, and know which games have a lower house edge, and perhaps a higher frequency of winning. An Advantage Player looks at the long term probabilities of perfect play, (or as close as is humanly possible) accounting for the variance (peaks and valleys). But a short term player might be more cavalier with their bank roll, make larger and riskier bets, press it up, and even play hunches and win a bundle. Skill is important, but Lady Luck also has a hand in this deal. My point? Well, if you're having a bad day at the tables, don't worry, your luck will change. And if you're on a hot streak....Quit while you're ahead! .
