The Cherries were left to count the cost of conceding two first half goals as they were beaten 2-0 by Birmingham City at the Goldsands Stadium.
Andrew Shinnie opened the scoring inside three minutes and Nikola Zigic then doubled the Blues’ lead 11 minutes before half-time.
The hosts enjoyed their best spell ahead of the break and goalkeeper Darren Randolph had to make saves to deny Marc Pugh and Lewis Grabban.
Grabban and substitute Ryan Fraser went close in the second half, but they were unable to find a way past a stubborn defence as Lee Clark’s team recorded their sixth game without defeat.
Eddie Howe named an unchanged starting line-up for only the second time this season, which meant starts for Eunan O’Kane, Harry Arter and Andrew Surman in a three-man midfield with Grabban as the lone striker.
The Cherries were aiming for back-to-back wins for the first time this campaign, but if they were to achieve the feat it appeared they would have to do it the hard way after Shinnie gave the visitors the lead inside three minutes.
Shinnie met Chris Burke’s cross at the near post and Lee Camp could do little to stop him scoring from close range.
The hosts looked for a swift reply, with both Arter and Pugh going close in the early stages. Grabban was then denied by Randolph, who managed to tip the top scorer’s header round the post at full stretch.
However, the Blues found themselves two up in the 34th minute when Jesse Lingard played in Zigic and he produced a clinical finish in front of the Steve Fletcher stand.
The Cherries almost pulled one back a minute before half-time when Arter’s through ball released Grabban and his shot went just wide.
Howe sent on Fraser at the interval, but his side really got going on the hour mark with Randolph making saves from Pugh and Matt Ritchie.
Tokelo Rantie was introduced for the final 25 minutes and he helped the side win a corner, which was guided over by Simon Francis.
Rantie went the closest to pulling one back with a header in injury time, but once again Randolph was equal to the effort.
