Since many years, there has been a long debate on the question that whether online poker tournaments are fixed or not. Both parties claim that they are absolutely correct but neither side has been able to put a solid proof that their theories are correct.
That answer lies in the visible patterns used by poker sites of which are called poker algorithms sa gaming. Many poker scandals have occurred in last years where cheating and collusion was found out by players that forced poker rooms to add in special poker algorithms to stop cheating and collusion by players.
Some of these algorithms will considerably change the percentages, the winners, and the result of play in on-line poker. The reason is clear; on-line poker is a computer-generated series of codes that is not exactly random in literal sense. Meaning that by adding in code to the software, the poker rooms are usually changing the possible results and make the game less random and more natural to a player that is responsive of the patterns occurring in the program.
For example, have you ever paid attention to the last stages of a tournament, a shortstack has not played a hand for maybe 25 or 30 hands, then suddenly he goes all in and gets called by one or more opponents. The shortstack will showdown a small hand while the callers will have a dominating hand and unsurprisingly the shortstack doubles or triples up by winning with his small hand.
This is a noticeable pattern often known as a fair percentage algorithm used by the poker rooms. The objective of this algorithm is just to make sure that a single player does not hold a wrong advantage over other players by winning the pots continuously. Moreover, it also stops a player from dictating a table or tournament by restricting the number of wins a player may have.
