Bad Heads up . . .need advice

This is my first time here. i play a lot of sit n go's online, and find that I almost always place, but rarely first. Usually I come in second. I am playing NLHE for $10. I know that I am weak heads up, so I am wondering if anyone knows of any books out there that could help me. I think my main problem seems to be playing hands like a K2 to a raise. I think I should be playing it (especially when they raise every hand) but I'm not sure. I do fine playing big hands and small cards like suited connectors, but anything else I don't know what I am doing. Any advice would be appreciated.

just a heads up, I know this forum isn't under the limit section, but that's basically all that is talked about in here. however I read this forum sometimes and they talk about stuff like this all the time, you'll have a lot better luck posting there

Thanks, I posted there as well. Didn't realize this was mostly limit.
