ever heard of harrington on holdem 2...

also, try playing a few headsup tournaments.

some basic information
Pretty much everyhand is worth a call from the small blind.
When your raising, you dont need to raise as much as you would at a full table.
Raising from the SB is good, folding from the SB is bad.
There is lots of flop play. And turn play. And river play. (If the stacks are deep but not that deep, then problaby just flop play and turn play)
headsup is fun.
