HU 2-7 adjustments

[rchandra]

When I'm playing 2-7 headsup I have trouble figuring out what I should do, and I think I play too tightly. If it's at a full table I'm used to being cautious from the SB unless BB folds a lot, and calling/raising liberally from the BB when SB opens. But with the blind sizes reversed HU I feel lost!
in the sb + button I know I want to play a lot since I have position but can I really raise stuff like 35 that I would call with in (normal) BB with position? If my opponent lets me I'll limp that sort of hand.

In the BB I don't like playing marginal/weak hands OOP but I am still getting excellent pot odds, and probably open-folding too much.

Fortunately (?) I'm not left in this sort of situation often, in a tournament blinds are big and we end up all-in soon, and in a cashgame somebody else will sit down. But I still feel lost!

Any general adjustments / guidelines when compared to normal play?
