Goalkeeper Mark Travers saved all three penalties in the shootout to help Bournemouth edge past League Two side Forest Green and reach the Carabao Cup third round.
After the game finished goalless, Travers’ saves allowed Philip Billing to score the winning spot-kick.
Travers denied Josh Mills, Kevin Dawson and James Morton in the shootout while Jordon Ibe’s penalty was also saved for the Cherries.
The Premier League side had created numerous chances in normal time but Forest Green goalkeeper Joe Wollacott produced a series of fine saves.
He saved from Harry Wilson and Ibe early in the first half, keeping Forest Green level in their first game against a top-flight side.
Wollacott then twice saved from Joshua King in the second half, the first a fine save with his boot when one-on-one, while Jack Stacey also hit the post on his Cherries’ debut.
Forest Green’s best chance fell to Junior Mondal but he fired over the bar from 12 yards in the second half.
Matt Stevens also went close for the League Two side but his effort was cleared off the line by Andrew Surman following a corner.
King and Dominic Solanke calmly slotted home their penalties in the shootout and, after Travers saved Forest Green’s three efforts, Biling smashed into the top corner to seal the win.
