Luck is very important in poker, especially when playing with few entries, whether it's tournaments or playing for
real money. It's perfect to play poker, knowing when and what to do, but if the card doesn't work, everything gets very sad and there is almost no way to change anything. In this case, all that remains is to endure and wait for luck to smile at you, that's why you need a lot of money to enter the game a large number of entries. In tournaments, you need to have money for 100+ entries, and in real money games, at least 30+. This is my personal opinion, maybe someone thinks differently.
