Kellie Pickler, Thomas Rhett and several other country artists will be playing a life-size game of checkers for a good cause at the 2015 ACM Awards Party for a Cause -- and Pickler's ready to win.

Pickler and Rhett will each captain a team in the Cracker Barrel Old Country Store Country Checkers Challenge, which will also feature Lauren AlainaKristian BushChase Bryant, Love & Theft and Jamie Lynn Spears on Pickler's team and Scotty McCreeryCassadee Pope,  Dan + Shay, Danielle Bradbery and Rhett's own father, Rhett Akins, on Rhett's team. Six lucky fans will join the two teams as well.

"The checker pieces are human, and then we kind of move them around," Pickler explains to The Boot. "And I’ve been talking a big game, so I've got to be honest, I’m a little nervous because I've been talking all this smack, and I’m horrible.”

Still, Pickler won't go down without a fight.

"I don’t know what everyone’s checkers skills entail, so we’re definitely going to have to have a team meeting and discuss some strategies," she says. "We’re going to win. I’m just going to keep talking a big game, keep spreading good vibes and be positive, that’s my strategy. I’m going to stay positive, I’m going to pray for a miracle, and we’re going to win.”

Pickler's team is playing for the USO (United Service Organizations), while Rhett's team will be playing for the DAV (Disabled American Veterans). The winning team's organization will receive a $25,000 donation, and the losing team's will get $10,000, both from Cracker Barrel and ACM Lifting Lives.

“I’ve worked with [the USO] for years now ..." Pickler says. "Just the effect that the USO’s had on so many people’s lives, it’s amazing to be a witness to that and to be able to be a part of it. I’m excited about working with the USO for this and just being a part of something that matters.

"And we’re all going to have a fun time," she adds. "We’re all going to have fun, and it’s all for a good cause, so we’re looking forward to it.”

The Cracker Barrel Old Country Store Country Checkers Challenge is set to take place during Saturday (April 18)'s Party for a Cause festivities at Globe Life Park in Arlington, Texas. The 2015 ACM Awards will air live from AT&T Stadium in Arlington, Texas, on April 19 at 8PM ET on CBS.
