anyone else NOT read poker books?

i just read a post that said, "where can i find written theory on when it's correct to bluff-raise the river?"

am i a big minority in thinking this question is a little nuts?

jesus, i always thought the game was basically obvious. i've never read a poker book. i mean the answer to when should I bluff?" is : you do what you gotta do! do you think the guy will fold? yes or no.

is there a whole other world of rote instructions the majority of poker players follow?
