Push pairs as if they were the nuts. If you get a pair pre flop it is so likely to be the best hand that you want to get as much money in as possible. Do the same with aces to a lesser degree unless the kicker is above average, in which case play it as if it were the nuts pre-flop.
You always have the odds to call from the small blind whatever two cards you are holding. Only fold the worst 20% when they auto raise a flat call. If they do this you can try limping with top 20% hands sometimes and try and catch them out.
I find deep stack HU to be pretty tricky myself and much prefer higher blinds. You have to find a good balance between patience and aggression, something only practise will teach you.
