Again, another standard situation, but it's something I feel like I need help with.

Blinds 50/100, effective stacks 1200. My opponent is a standard fish. He's not putting a lot of pressure on me, limping his button, checking down lots of hands, etc. His calling range if I push is something like A8+, KJ+, and any pair. It may be a bit looser/tighter, but I can't do much more than guesstimate here.

So what's my pushing range?

What's my range against a lagtard with the same calling range, but is putting alot of pressure on me?
