The big drawback in a public poker whether in a casinos or in a club is the machination of cheating practiced by many professionals players. Victims of the cheated, most of the time, weren't even aware that they were cheated at. They weren't even suspicious.
In this scenario, professionals have nicely executed their cheating because they employed a method of cheating that is not visually detectable. They have done this many times that they do it casually and naturally even the club management and other dealers weren't aware of it. Professionals have no qualms to cheat sometimes and their reason is to offset what the house collects daily.
There are many kinds of cheating methods that we can recognize in various casinos or spot at different online gambling sites. The first set are still employed by many professional cheaters today through card manipulation such as blind shuffling, stacking (overhand stacking, rifle culling, undercut stacking, Las Vegas riffle, etc), peeking, pulling through, culling the deal, false cutting and riffling, and crimping.
Another way to cheat is by daubling. By daubling, cheaters stain the cards either by nicotine or by other secretive means. Other means of cheating is by colluding with partners by card flashing, spreading, signals and cross-firing.
Some people are obsessed with winning the money or winning the game. Cheaters like to win the money; good players like to win the game. To be a consistent winner some good players become cheaters and they join professional cheating establishments to become part of their colluding efforts.
Other players, the really good poker player, comes up with strategies himself to deal the cheating from others. If you can read a tell good enough, you can also spot cheating by an individual. What's hard to spot is two or more players cheating against you. Partnership cheating are always employed in high-stakes lowball. In this game, cheating can significantly lower the player's investment odds that there's no way for him to win even with the best strategy, skill and alertness.
Contrary to what you hear or watch on the movies or in plain gossip, any player can cheat. Like poker strategy, cheating has its methodologies. Even amateurs with little practice can master invisible cheating. A pro player tries to learn cheating method himself, not to cheat, but to incorporate their methods in their skill in reading tells. That way he can spot cheating and colluding players. Signals between partners and card flashing can be detected with a kind of alertness specifically practiced by a pro to catch a cheating hand.
However, the pro should be aware that not all high-stake poker games have cheaters. He should realize instead that every game is open for cheaters to exploit. So with all due fairness, a pro doesn't accuse anyone of cheating. Instead, he's good enough to prove that you are.
