Shaw will supplant Richard Panik on the top line. Panik, who played well in Game 5, will move to left wing on the fourth line with Andrew Desjardins and Dale Weise. Chicago's second and third lines will remain the same.
Under Quenneville, the Blackhawks have faced elimination in Game 6 five times and pushed the series to a seventh game in four. The only defeat was April 23, 2012 against the Arizona Coyotes.
The Coyotes won three games at United Center in that series, which is what St. Louis is trying to do after winning Games 3 and 4 in Chicago.
"I don't really care when we win," Blues coach Ken Hitchcock said. "I just want to win. I don't care when it is. This is a [heck] of a series, two teams just going at it. We feel that we've got enough information and knowledge, knowing how deep you have to go [to win]. The last game showed that, but we just want to win the series, and it doesn't matter when, if, where, whatever. We'll play 'em on the street if they want. We just want to win the series."
The Blues are expected to use the same lineup as Game 5. They held an optional morning skate after not practicing Friday, giving those who didn't skate an extra day of rest after logging high minutes Thursday.
"We know what we've been through and we just felt like today was better to go at it this way, knowing where we're at," Hitchcock said. "So, we made that decision to keep some people off [the ice], so we could pour it into tonight and not waste any energy or physical exertion this morning with some guys."
