Charlie Adam's second-half penalty handed Blackpool a 2-1 victory in the first leg of their Coca-Cola Championship play-off semi-final against Nottingham Forest.
Ian Holloway's Seasiders, promoted from Coca-Cola League One via the play-offs in 2007, hit back from a goal down at Bloomfield Road to edge their noses in front after Chris Cohen's wonderful strike had given Forest a 13th-minute lead.
Cohen found the top corner with the outside of his left boot, but Blackpool levelled 13 minutes later when Seamus Coleman weaved his way across the area and found Ian Evatt, who played the ball back across the six-yard line for Keith Southern to convert.
Adam, the £500,000 summer signing from Rangers currently interesting several Barclays Premier League clubs, then grabbed the winner from the spot in the 57th minute after DJ Campbell had been tripped by James Perch.
Forest have an impressive home record this season and will still fancy their chances of turning the tie around. But Billy Davies' side have not won on their travels now since a 3-1 win at West Brom back in January lifted them into an automatic promotion spot.
Home goalkeeper Matt Gilks denied them a late equaliser when he turned away Forest substitute Robert Earnshaw's low drive in the dying moments.
