The PokerStars World Championship of Online Poker (WCOOP) will run from September 2 to 17 and has $70 million up for grabs. It has become a hugely popular series of tournaments with virtually every level of buy-in imaginable. It will offer two main events this year, including a $55 buy-in tournament with a $1-million prize pool, and a second, $5,200 buy-in event with a $10-million guarantee. Rival online poker site partypoker doesn’t want PokerStars to have all the fun, and has announced its own monster series of tournaments, offering a guaranteed $60 million.

The partypoker Powerfest Online Poker Series is scheduled for September 2 to 23. There will be a total of 670 events and will have a combined prize pool of at least $60 million. As with the SCOOP, there will also be something for everyone, with buy-ins ranging from $1.10 up to $25,500.

This is the ninth year for the Powerfest series and could be the largest in the history of the poker portal. Starting this Thursday, partypoker will offer players a chance to win part of a $50,000 pool of tournament entries. Players who log a significant amount of time playing on the site between then and September 1 will have the opportunity to win free tournament tickets.

There will be a total of 20 championship events during the series, of which 15 offer a prize pool of at least $1 million. The largest is a $25,500 Super High Roller tournament on September 20 that offers a $3-million guarantee. A few of the tournaments include:
