i do, but am only really good against live players (as apposed to computer players like zappa). most advanced players have set openings, middle games, and end games in mind. i only focus on controlling the middle, castling, doubling my rooks on an open column, and attack attack attack. it drives my opponents nuts, and is a good way to mess up their set patterns. also, i can usually only see about five or six moves ahead for each combination, but i do play very fast.
