input: [Required IQ] 0 [Group(s)] - [Name] Course Checker [Affects] Partner Pokémon [Other notes] In the case of linked moves, Course Checker will only check the first one. So if the combination is Growl+Razor Leaf, the Razor Leaf could still be wasted as it has more terrain limitations than Growl. [Game description] 
output: If this Pokémon targets an enemy with a move or a thrown item, it will first check and other Pokémon that may get in the way, then stop the action if such an obstacle exists.
