The fundamentals still apply pretty much. The most important street in LO8 is preflop. What happens on the flop and beyond is often predetermined by your preflop decisions so this is the street you should be focusing on for both 6 max and full ring.
play around 25% of all the hands you are deal, raise from late position and call from early position (in 6 max raise from every position) the following hands.
A-A-2-x
A-A-3-x
A-A-4-x
A-A-5-x
A-2-3-x
A-2-K-K
A-2-Q-Q
A-2-J-J
A-A-x-x
A-2-K-Q
A-2-K-J
A-2-x-x (suited ace)
A-3-K-K
A-3-4-x
T-J-Q-K
K-K-Q-J
2-3-4-x (fold if there is no ace on the flop)
Any 4 cards between a ten and an ace.
The number one thing to focus on is "betability". Play hands that you can bet post flop, so nut low draws nut flush draws big wraps etc. You win money by betting and hitting your hand so no chasing gutshots headsup and non nut draws multiway.
