Substitute Keith Treacy haunted former boss Eddie Howe after grabbing a point for the Clarets at the Goldsands Stadium.
Treacy, a forgotten man during Howe’s tenure at Turf Moor, was introduced alongside Ross Wallace just after the hour, and the pair combined moments later as the Irish winger fired Wallace’s deflected shot in to the roof of the net.
Tokelo Rantie, who opened the scoring spectacularly in the 1-1 draw at Turf Moor, broke the deadlock again in the return fixture when heading home veteran defender Ian Harte’s corner just after half-time.
On a testing surface, which the AFC Bournemouth ground staff did admirably well to clear surface water to pass a 7-30 am pitch inspection, the Clarets struggled to find their flow against the home side’s direct approach, with the heavy carpet not conducive to Burnley’s intricate, pressing style.
Though Rantie, strike partner Lewis Grabban, and Mark Pugh worked the triangular well in the early stages, the productivity of the latter was questionable despite the space the former Claret had manufactured in behind Kieran Trippier.
But the Cherries predominantly looked to utilise the pace of the forward pairing, aiming to drop the ball beyond Michael Duff and Jason Shackell, though the defensive duo marshalled their task expertly again.
The visitors almost found a route past their hosts when breaking from a Bournemouth attack; Michael Kightly found the space behind Steve Cook and Tommy Elphick with a bending cross, but Simon Francis did enough when getting a leg to the ball to prevent Sam Vokes from breaking in to the box.
Full-back Francis was then involved at the other end almost instantaneously, when Scott Arfield’s wayward headed clearance was touched in to his path, but Tom Heaton was equal to the effort.
Francis was proving an economical outlet for the home side, with his clipped pass being touched in to the path of Rantie by Grabban, but Shackell raced across to execute a superb block on the edge of the penalty area.
However, after soaking up those brief pockets of pressure, Burnley had a great opportunity to penetrate the Cherries backline. With Bournemouth committing men high upfield, Kightly broke courtesy of Harry Arter’s slip on the centre circle, but in a two-on-one attack with Arfield, the Stoke City loanee was frustratingly wasteful as he showed Eunan O’Kane too much of the ball.
Then, once Grabban sliced a volley wide, and Howe introduced Shaun MacDonald at the expense of O’Kane, referee Graham Scott drew a close to the first half.
After the restart, the Clarets fell behind, disappointingly to another set-piece.
Like goals conceded against Sheffield Wednesday and QPR, the Clarets were undone by Harte’s sweeping corner, and somehow the slight frame of Rantie rose to head across Heaton and in to the corner. It was only his fourth goal of the campaign - one coming for Malmo in the 7-0 Europa League thrashing of Hibernian, with two of his three for Bournemouth coming against the Clarets.
Still, the Clarets failed to find the energy and guile of previous performances, though they pierced the Cherries defence soon after when Marney dropped off the shoulder of Cook to latch on to Trippier’s cutting pass, but Danny Ings, on his return home, uncharacteristically fluffed his lines from Marney’s squared pass.
Once Ben Mee pulled a desperate effort wide from distance, with the Clarets restricted and lacking invention, Dyche made a double change bringing Treacy and Wallace on for Arfield and Kightly respectively.
Bournemouth’s central defensive pairing had kept the Championship’s hottest strike partnership quiet throughout the afternoon, but they couldn’t stop the two substitutes from merging. Wallace pulled the trigger with his left after cutting past Harte, and as the deflected attempt was diverted to the back post, Treacy stabbed a composed effort past Lee Camp and in to the roof of the net.
Unfortunately, the Clarets failed to craft another attempt of note from that point while the hosts could’ve snatched maximum points.
Grabban raced clear when the ball fell fortuitously for him, and after Shackell forced him wide, the striker forced Heaton to save with his feet at the near post from an acute angle. From the resulting corner, Yann Kermorgant, who had replaced Rantie, found the wrong side of the post when his downward header troubled Heaton.
Scott’s next decision was a dubious one, but it provided a clear opening for Bournemouth. Trippier’s collision with Grabban looked innocuous, but the match official awarded a free-kick, though the incident seemingly took place inside the box. Kermorgant bent the set-piece around the wall but the effort also whistled by the upright.
Sandwiched in-between a change from both Howe and Dyche - with Ashley Barnes replacing Vokes and Brett Pitman introduced at the expense of Grabban - Francis clipped the bar with a thumping effort from Pugh’s assist.
It’s another point for the Clarets in their promotion push, and they’ll take heart from that going in to the crunch Championship fixture with rivals Nottingham Forest on Saturday.
