This is the main reason you need to know the *ideas* behind the openings--to know what to do when a player varies from book. If you know *why* the best moves are best, then you can usually figure out over-the-board how to refute anything that isn't a top book move. Sometimes the problem is an upcoming lost tempo, sometimes an upcoming doubled pawn, sometimes an upcoming inability to castle, sometimes a lost pawn, sometimes a unit placed where it has little scope, sometimes a poisoned pawn, sometimes a piece placement that allows that piece to be pinned against the king and lost, etc.

(p. 1)
An apt illustration occurs in
deviations from "book". A game
begins with 1 e4 f6. The reply is
bad, so bad in fact that it will
not be found in any collection of
standard opening moves. What to
do about it? The man who has
memorized oodles and oodles of
moves without understanding
them is at a loss; he will not even
be able to give a good reason why
the move is bad. But the man who
knows that Black has neglected
the centre, deprived his KN of its
best square, and weakened his
King position will find it a simple
matter to refute his opponent's
faulty play.

As a player who likes to play slower games (multiple hours) or 20-30 minute rapid games. I analysed the last 100 games with 5 minutes time control. Of the hundred games about 75-80% of all the openings i played against players with 1800-1950 rating are eather junk or sidelines avoiding theory in the first 6 moves. Some of the sidelines are sound and sometimes quite dangerous but most opponents i played just avoided theory whatever the cost.
I`m not very good at very fast chess games. 5 minutes really is a bit against my nature but i do like to get better at it.
What are the best ways to combat these kind of players? Without having to study more openings. I currently play main line openings and rather not spend more time studying new openings at the moment. In a lot of games i get behind in time when we reach the middle game and get frustrated when i lose a better position. Fighting against the clock
