tasched

Hello, sorry if this is the wrong spot for a post like this, but I'm confused on how the whole 'selected adjacent pokemon' function for some attacks work - does that not mean I can select one of the pokemon next to the pokemon I select initially? I saw there are also moves that say 'selected pokemon' that seems to function the same - I tried asking in global chat, but I was told that it only hit's one pokemon. Any help would be appreciated.
