Chase will actually block the first punch, realize that, 'Shit that's training, I'm screwed' and proceed to let her hit him the second time she throws the punch, which she undoubtabley will. Garth...that's a tricky one...for one thing both like grass type pokemon, and knowing Chase he will be interested in anything to do with berries as a means of keeping his grass pokemon healthy and safe. Alvar...Chase wants to battle him just to prove that he's still good at it.
