Prior to all the good bonus sites closing their doors to US players I was a shameless bonus whore.. LHE is spectacular for clearing bonuses and racking up player points with minimal exposure.... Provided you're just not blatanly donking off money.
Keep in mind I'm a BR nit but as a general guideline 300-500 BB's is considered a standard roll for a full ring player. 6 max is a bit more aggressive and swingy, personally I feel 500 BB's is about the minimum you should have.
The 2 best sites (besides here obv.) I found that have a lot good shorthanded LHE info are these:
1.
http://www.flopturnriver.com/6-Max-Limit-Guide.html This is Hypers 6 max guide, very good oveall 6 max strategy there... Bear in mind though this was written a few years back and mostly for the games at Party Poker which were super soft.
2.
http://www.beat6max.com/ A collection of articles, concepts, and threads from places like 2p2 and a few from our very own MK when he used to put together coherent well thought out posts together.
That should give you a good jump on things, that and post any problem hands, there aren't many LHE players on this site but the ones that are here can still give pretty damn good thoughts and analysis.
