Definition of freezeout
When we talk about "freezeout", we are talking about a freezeout tournament. Tournament freezeout is a tournament in which you cannot buy back or add chips. In an rebuy tournament, it will be possible to buy back chips during the first hour or two, depending on the structure, but in a freezeout tournament, you pay your entry fee and when you run out of chips, you are eliminated.
freezeout vs. rebuy tournaments
Tournament freezeout is played with a different mentality than tournament rebuy. Firstly, in freezeout tournaments, the cost of our buy-ins's may be higher than when we play an rebuy tournament. If we play an rebuy tournament and we usually make 1 or 2 buy-ins, it leads us to a higher total than if the tournament was freezeout. So, a player playing an rebuy tournament at freezeout euros for example will be able to play freezeout tournaments at 20 or 30 euros. Then some players will have a very aggressive approach in buyback tournaments. Some will take much more risks with a logic of chip accumulation. In freezeout, it will be necessary to be more conservative since it will be impossible to redeem. As a general rule, it is also easier to bluff in freezeout tournaments, players are more conservative.
