he's not really a counter to marth...
Spacing ftw...
And isn't this question EXACTLY why we have 2394101 Ike guides. I mean you couldn't have asked a more general and aimless question. What are strategies with Ike? For God's sake it's as if you were trying to define what a guide is only in question form.
If guides don't do anything for you then play people with Ike and watch videos with him. Basic strategies with Ike are to space and use his aerials and other moves effectively. This is a valid statement for any character, I know, but it's particularly important to be careful with Ike, but simultaneously aggressive. Watch your opponent. Know when to double jump fair, ff nair, tilt (Ike's tilts are powerful and just generally awesome), AAA (really, really effective), Aether (**learn the spike with it**), and QD (i.e. don't use it unless your pursuing someone you just beat the sh*t out of, or getting away).
Ike is a character of few combos though, and the fact that you asked for examples makes me think that you are either very hopeful, or haven't played much with Ike. This is why he's a very prediction oriented character. He's a strong, single strike fighter.
Anyway, understand all of the above to some agree (someone correct me if I have no idea what I'm talking about) and then read a guide, maybe watch some matches from some reputable Ike users, but above all go play with him.
