Say the game is tied in the bottom of the 9th, you have a runner on third and one out, is there a way to guarantee getting that runner to home plate, even if it requires the batter to sacrifice himself?

Say the game is tied in the bottom of the 9th, you have a runner on third and one out, what is the best strategy for scoring a run and winning the game? Is it a play that requires the current batter to sacrifice himself, or is that risky since you're then down to only having one batter left? Should the batter bunt it, or only bunt it when the strike count is at 2?
