It is very important also to say if you are better and can not calculate the sharp variants till the clear valuation, you should give up them at some point (it depends particularly on the time control) and chose the simple continuation that preserves the advantage (probably a bit reduced one), of course if you see it. Otherwise you take the risk to overspend the time enormously and what is the most important to lose the concentration completely that can even cost you the game.}) 16... Bd5 17.
