Always seek a forcing moves!
Principles of chess: These don't have to be in any order. Just principles to remember.
maximal activity (pieces in opponents side without being captured)
material (to take is mistake, an even exchange) Try to win points (but be watching for traps)
Always seek to attack/most forcing moves (checks, captures, other attacks)
No Attacks? Then increase activity of your worse piece and/or decrease activity of opponents best piece
