That may be fake. The nickname "RAFA" is too simple
Not fake - see this - http://www.poker10.com/rafa-nadal-de...n-event-n10659
He's called Rafa as he's doing it as part of a deal with Pokerstars - doubt he'd be playing online poker if he wasn't getting paid $500,000 a month to do it. It was announced that he'd play this tournament - apparently a big deal in Spain.
And that Federer avatar was actually used by someone...
