My magic-user was a friggin' terror in the dungeon; thankfully my DM was gracious enough to allow us to use the "open the door a crack...fireball in, slam the door and jump back" strategy.:
I used to let PCs do that back when I was 13 and didn't know any better. Which leads to My Best Fireball Story:
PCs are slogging through G-1-2-3
Against the Giants. (It's been so long, I don't remember exactly which giant stronghold they were in.) They come to a closed door, the thief listens at the door, and the party decides the bad guys on the other side are tough enough that they need to soften them up with the "fireball and shut the door trick." Unfortunately for them, the door is locked and the thief fails this lockpicking roll.
The players' brilliant plan? The magic-user will
start casting Fireball,
then the ranger will force the door open, and
then the magic-user will send the fireball through the door, and
then the ranger will shut the door.
Yeah, what you're imagining right now is
exactly what happened.
The ranger, despite wearing a
girdle of giant strength (and thus having something like a 95% of forcing open doors)
fails. The magic-user blasts the ranger
in the back with a fireball. The party takes massive damage -- one PC dies on the spot. The ranger (still alive, because he was 100-hp tank) is knocked through the flaming remains of the door into the room, and combat begins.
On a more positive note, I did rule that the NPCs inside the room were suprised by the exploding door and flaming ranger, because I know I sure as hell would be.
Nobody ever tried "fireball and shut the door" after that.
