A lot of people don't understand bishop sacs and bishop + knight attacks on f7 and f2. I still have issues with it myself but I've gotten much better. If my opponent pins my knight and then just throws away the bishop pair for no apparent reason and/or sacs on f2 or f7 in the situation you've described, it's a pretty good indication of where the game is going after that provided I don't make any mistakes or allow myself to go in the tank for too long and look up to find myself in time trouble.
