The team who find cold comfort at home against the side who grow nauseous as soon as they leave familiar territory.
Few would have gambled on anything other than a draw for Birmingham's trip to Blackpool, and only Scott Dann's late intervention prevented two punch-drunk sides conforming to stereotype.
This was one of those occasions where something had to give; Blackpool have struggled at home and Birmingham have been abject away. Indeed, Alex McLeish's side travelled to Bloomfield Road without a win on the road all season but looked confident, purposeful, menacing, and spurned two opportunities to take the lead before Alexander Hleb struck after a mistake in the Blackpool defence.
Birmingham hit the post twice in as many minutes -- first through Cameron Jerome, then Sebastian Larsson's low free-kick -- before DJ Campbell skewed an equaliser into the corner which seemed to sum up Birmingham's luck on the road.
But after Charlie Adam struck the post for Blackpool, Dann held his nerve well to coolly slot home Roger Johnson's knock-down.
Birmingham's hex is broken. Blackpool are just starting to feel cursed.
