Today’s Texas Hold’em poker is definitely looser than it was a decade ago and professional players like that style. Loose play will always favor the pro because the more hands that are played by the amateurs, the more mistakes they will make.
While loose play ultimately will favor the poker pro, it is not always easy to play against a maniac. Playing against a maniac player who plays every hand can be difficult. That is why the successful poker pro can succeed in a loose game while the amateur can not. Discipline is a huge key in poker and professional poker players have more of it than losing players.
When the professional player encounters a loose table he understands that the maniac players will eventually give their money away. It might not happen right away but very few players in the world can play every hand and make money consistently. Maniac poker players will eventually lose all of their chips. The poker pro is there to take them when he does. Many poker players don’t have the discipline to play against the maniac and become frustrated. Sometimes that maniac is going to win a big pot but eventually he will give it all back. The poker pro knows this and takes advantage.
Loose poker players are almost always losing poker players and that is why professional players love playing against them.
