The 2007 World Series of Poker (WSOP) began on June 1, 2007. The $10,000 (US) no-limit Texas hold 'em Main Event began on July 6 and was completed on the morning of July 18. All events were held at the Rio All Suite Hotel and Casino in Las Vegas, Nevada by Harrah's Entertainment, which has run the annual event since its purchase from the Binion family in 2004.
For the first time players began each event with double the amount of chips as the buy-in. This means that players in the Main Event started with 20,000 chips. The blind structure has also been increased and some blind levels removed but slowed to allow for more play.
In addition to the $50,000 H.O.R.S.E. event, which was first played at the 2006 World Series of Poker, this year there were two additional H.O.R.S.E. events with lower buyins ($2,500 and $5,000).
Tom Schneider, who won two events and made one other final table, won the Player of the Year Award. Michael Binger and Chad Brown led all other players with eight money finishes.
The annual celebrity event was changed this year, as it became a pro and celeb event called "Ante Up for Africa", hosted by actor Don Cheadle and poker pro Annie Duke. The final two players, Dan Shak and Brandon Moran, agreed to share first place and donate all prize money to charities in Darfur.
The last woman standing of the 2007 Main Event was Maria Ho who finished in 38th place.
Also this year, KEM Plastic Playing Cards were once again used for the events, rather than Copag brand plastic playing cards, which were used during the 2005 and 2006 WSOP.
