Preflop Strategy - heads up w/ chip lead

[AceofSpades]

You have 6,000
Opponent has 2,000
Blinds are 100/200

In this type of situation what should my general objective be? To maintain the chiplead? To try and cripple my opponent? Should I take a possible 40/60 all-in and hope to use my chips to get lucky?

What hands should I fold in the SB if any?
What range should I raise with?

Are you raising purely for value in these kinds of situations or trying to steal the blinds?

Should I raise any two if my opponent is pretty tight?

Autobet any flop if first to act?

I know those questions are kind of vague but I'd like to improve my heads up preflop play and it's hard to have hand histories for that kind of thing.

If your opponent is on the tighter side I would definitely expose that and start jamming a lot of hands preflop and if completed to. You have to do so selectively, though, because you don't want him to get the idea you're pushing for the sake of bullying him around.

If your opponent is looser/passive though, take some cheap flops and stab at pots that he doesn't want. 2/3 pot bets in or out of position generally do the trick. Push some pots preflop, but more selectively.
