In reality the BBEG will never scry the players at first. He will send minions to find the PCs. One of these minions will have a way to send a message (via spell, device or even a flamed arrow in the sky would do with other minions watching for it.)
When the minions have warned their boss, he will then scry the minions and their fight against the PCs as to learn their tactics and their relative strength. After a few times, said boss will prepare ambushes along the PCs' most probable travel path.
Through a few encounters, the BBEG will learn PCs' tactics and will adjust his spells/forces accordingly. The will be to use minions and everything in his power to neutralize at keast one if not two PCs. Divide and conquer is still a viable strategy.
And good players will do the same! Very often, players will have the basic layout of the BBEG's lair/base/keep before entering it. They will even have a basic idea of the forces in presences! Knowledge is half the battle. It was true during Sun Tzu, it still is.
