A back game is a comeback strategy where you deliberately hold two anchor points deep in your opponent's home board, hoping to hit them late and turn the game around. You usually adopt it when you are far behind in the race and cannot win a straight run. By keeping anchors, you stay safe and wait for the opponent to leave a blot as they try to bear off. If you hit that late shot, you can trap their checker and swing the game. Back games are hard to time and risky, so they are an advanced tool rather than a beginner's first plan.
