In freeroll tournaments apply the normal dynamics of poker is literally impossible, particularly in early stage.
Here it is necessary to adapt their game and their strategies to a field of players who usually are beginners. A freeroll tournament is the pinnacle of the worst: novice players, donks, and so retards infest the tournament every where.
As a result, immersed in this broth where the all-in in the first few levels rained like snow in Cortina d’Ampezzo restrict your calling range and play tight. Also, do not want me there the poker purists, go ahead all you want and go limp as often as possible in the family pot.
In the middle stages however there is some hope to be able to start playing poker. Be careful with the latest loose cannon with which you have to apply the same strategies of early. In this you will begin to find players a little ‘more sensible (although poor average) and you can start using in normal canonical strategies: a study of the attitudes of opposition and steal raise.
Generally the player sensible little fear aggression and oppose your bids only with real hands. Enjoy.
The late stage and the final table are the stages in which a freeroll is closer to a normal mtt. Especially when the freeroll offers a limited number of tickets this stage is almost always very conservative. Everyone will have to apply their “game” to get the better of others.
