Many players, especially at lower limits, often don't have the balls to pull off big bluffs, which in turn makes them very exploitable and predictable in the eyes of thinking opponents, who simply stop paying them.It is important to remember that poker is a game of ups and downs. And to survive the downs, you need to play rationally and with a cool head during the ups.You should always create conditions for yourself with maximum edge. That is why it is best to leave your ego at the door when playing poker.You need to understand that to get "into the money" in a tournament you need to earn at least triple your starting stack (and often even more). So instead of being cautious and playing a closed style, you need to show solid and aggressive poker early in the tournament to build a deep stack.
