I'm strictly a SNG player but would like to try get into limit cash games. If you look at all the pros, they seem to be consistently making their living from cash games, not tournaments. The highest I've ever played was 3/6 at the local cardroom when waiting for a tournament to start. I have about a $4k bankroll and would like to start 4-tabling the 5/10. However, I'm pretty sure my limit skills are mediocre. Can you guys recommend some good books to start me off? Thanks!
