Poker legend Phil Ivey sent a mysterious Tweet last night that got poker fans everywhere scratching their heads....and sent the forums into meltdown.

The 35-year-old, currently 3rd on the all time poker money list, was relaxing in Las Vegas after playing in the NBC Heads Up Championship, which was won by Erik Seidel.

But the secretive eight-time WSOP bracelet winner - who only started Tweeting again earlier this month after a long break - then caused a right old stir.

"After NBC Heads Up, I've been working hard on my latest endeavor with many of my top poker friends," he posted.

Within minutes that simple message had the social networking site buzzing and a thread called 'Ivey's Tweet' popped up on Two Plus Two.

Among the more sarcastic suggestions, including "Breaking 80 from the back tees imo" from JackRandall and "He's going to conquer the Starcraft 2 world" from bbfg, there were some serious theories.

One poster suggested it was related to Match the Pro, the much-hyped new project from Full Tilt Poker also involving Tom durrrr Dwan.

Others thought a new TV show was in the offing.

Mr Ivey, over to you...
