If a player knows he has a freeroll
If a player knows he has a freeroll he can raise the pot with impunity, and often a less-skilled opponent with a good hand who does not realize that he is on the wrong end of the freeroll will continue to put in raises with no possible hope of gain. Freeroll tournamentThe term freeroll is also used to describe a tournament with no entry fee but the use of the terms 'free' and 'no entry fee' can be misleading because some freerolls require a payment at some point to gain entry to the tournament.
In a typical pay-to-play tournament
In a typical pay-to-play tournament the prize pool consists of an accumulation of the entry fees minus a "fee" which is retained by the house. In a freeroll (at least from the players' perspective) the prize pool is essentially a "donation" provided by the house. Of course, in most freerolls the house is able defray a significant portion of the prize pool (or even turn a profit) by charging for food and beverages, sponsorship fees, admission to spectators, broadcast rights fees, or any combination of these. Sometimes a particular cardroom or casino (either traditional or online) will offer a freeroll tournament to frequent players. Invitation-only tournaments are frequently freerolls. Freerolls at Internet online hold'em poker sites should not be confused with their close counterpart --
