Any one know if it is any pokerseries in Vegas march 10 to march 17??
Like Venetians Extra Vaganza?
Nothing has been announced this far out. This year, Venetian ran a March Weekend Extravaganza March 14 -19, which I believe did cover the first weekend of March Madness, sounds like the time you're asking about. So they might do it again in 2018.
Most rooms would though would rather not have a series then because there are so many cash games running, and the folks in town for the basketball don't want to be tied down to a poker tournament while they are watching/betting the hoops tournament.
