Compare that to my second game, where I made three wrong moves:
A. Walking my Dread off my home objective
B. Not falling back to grab the four VP center objective
C. Not advancing my Speeders up to contest the two VP objective that I didn't hold.
How to avoid making a "wrong move"? Stay focused on your game plan. Don't get caught up in the glee of killing while forgetting objectives. Be able to ask yourself as your opponent moves: "How do I counter that?" Once you have that LR full of nastiness stunned, you don't have to keep pouring on the fire in an attempt to immobilize it, move on to other targets. Be ready to throw away any unit if it buys you the time or provides enough attrition losses to make it worth retaining that objective, getting a turn of firing or covering for that assault. Or even just makes your enemy step to the side for that one little turn.
