The Robins are just a point off the League Two automatic places after a run which has seen them lose just one of their last nine matches.
With games against two of the teams above them over the Easter weekend, Yates is hoping his players can step up to the challenge.
He told the club's official website: "We've all got to hold our nerve now with our final six games to go and see where it takes us.
"We just need to make sure we're as good as we have been. We've only lost nine games all season, the second best record in the league.
"We've got two really tough games. If we win both it will really propel us. We're trying to take all six points."
