Adding to this, each obstacle, from Fluffy through to the potions is 
involved in one of the areas of expertise for HRH. (although perhaps 
Dumbledore was expecting Neville to be with them, to tackle the 
dangerous plant under the trapdoor). The key and the broomstick were 
for Harry, the game of chess for Ron and the logic puzzle for 
Hermione. (the troll is a tricky one however).
