Joe I don't believe there is a complete or definitive answer to your question. To my mind certain players extract advantages from a sacrifice better than others mainly because they read the position better.Mobility of your pieces enables you to atack and threaten your opponents pieces and King safety. Of course this is no guarantee you will be successful especially if your opponent defends accurately. Time pressures too plays a huge role in determining many outcomes as well. .So in my humble opinion it's never easy deciding whether to sac a piece for mobility unless you are absolutely sure that somewhere down the line you gain an advantage.Then of course if this is the situation the sac move is not deemed a genuine sac.Sigh this is getting rather complicated isn't it? I wonder what other people think? Allan
