The Seasiders opened the scoring after only five minutes. Jordan Brown played a ball through to Hansson in the box, with the winger finding the back of the net from a tight angle.
Ahead of the break, Forest found their equaliser. A major bit of miscommunication between Franco Ravizzoli and Fraser Horsfall saw the pair collide while trying to clear the ball on the edge of the box, allowing Kalum Thompson to tap the ball into an empty net.
Following the restart, the Forest attacker almost had a second, with a save needed to stop a shot from point blank range after another defensive mix-up.
In a rare second half attack, Blackpool were able to edge their way back in front. Josh Bowler produced some quick feet to go past a number of players, before slotting past a motionless Bott.
Here’s how the Seasiders performed:

2. Franco Ravizzoli - 5
Franco Ravizzoli, along with Fraser Horsfall, were at fault for Forest's equaliser at the end of the first half, with the pair simply not communicating while attempting to clear the ball. Beyond that, he was on hand with a couple of good saves to deny the young visitors. Photo: Gareth Evans
