Need some tips on a NL heads up game tonight.

[Eihli]

I don't play NL often and even less commonly play heads up, but I'm going to be playing a game tonight and could use some tips so I'm not spewing chips. It's a 5/10 $1k game against someone who calls, in what is my opinion way too loose, from the BB with things like T6o, and that's about all I know about his play. How should my normal full ring limit game adjust to play well at heads up no limit?

Thanks.
