We always try and wait until a few hours before an event to publish UFC odds to provide you with the most accurate lines.

A lot can happen in a day or two, which can drastically affect your bets. Case in point, the photos of UFC Light Heavyweight Champion Chuck Liddell partying in a Vegas nightclub just two days ago.

Maybe it means something, maybe it doesn't.

Taking all the factors inside -- and outside -- the Octagon into consideration, however, before wagering any sum of cash is always a wise choice.

In addition, prior to placing any bets we recommend that you check BetUs.com for the latest odds because the ones below could change.

Here are the most recent odds for UFC 66:

Favorite: Chuck Liddell -200
Underdog: Tito Ortiz +160

Favorite: Chris Leben -180
Underdog: Jason McDonald +150

Favorite: Forrest Griffin -306
Underdog: Keith Jardine +276

Favorite: Andrei Arlovski -500
Underdog: Marcio "Pe de Pano" Cruz +350

Favorite: Michael Bisping -380
Underdog: Eric Schafer +300

Favorite: Thiago Alves -110
Underdog: Tony DeSouza +110

Favorite: Gabriel Gonzaga -300
Underdog: Carmelo Marrero +220

Favorite: Yushin Okami -450
Underdog: Rory Singer +325

Favorite: Christian Wellisch -145
Underdog: Anthony Perosh +115

Just a quick note on how this works: The Liddell-Ortiz fight has Liddell favored by -200. Therefore, you would have to wager $200 to win $100 plus your initial $200 bet. Ortiz would pay out $160 on a $100 bet as the underdog.

Here's a tip from a handicapper at BetUs.com:

Liddell is the favorite and rightfully so. He is a standup fighter that is going to be on his feet for the majority of the match. I foresee Chuck setting a furious pace and dominating by the end. The opening minute may be fairly even, but there is no way Tito Ortiz is going to pull out a win in this massive contest.

Hopefully, that helps.
