The Blue Jackets are 2-7 all-time at Nationwide Arena in the Stanley Cup Playoffs and played poorly in losing 4-1 in Game 4.
"We think we can put together a much better effort on home ice, especially with how great our fans are and have been," defenseman Ian Cole said. "We take a lot of pride in this being a tough place to play."
The Capitals don't want the first period to be a repeat of the third period of Game 5, when they were outshot 16-1.
"We better be looking at that first shift in this rink," Capitals coach Barry Trotz said. "It's going to be loud. They're going to be very determined."
