10/20 limit? Sklansky's books are best for limit games. This is assuming general play is fairly TAG.
If the game runs closer to a 5/10 limit game I'd still suggest reading Sklansky's books, but also read some on playing low stakes as you'll want to take a different approach to the limp fest games.
If instead you're asking for advice or tips to go play $2knl, you can set your money on fire instead of sitting down and wasting your time along with your money.
