In the opening chapter of the book, Winning chess tactics by Yasser Seirawan, he mentions Silman's rules to ascertain weather there is a tactic on the board and some other fella, I've forgotten who. I've also managed to forget the rules!
If I recall correctly, "Silman's rules of recognition" are intended only for tactics involving sacrifices, and therefore they won't point out every kind of tactical opportunity (for example, trapping the opponent's queen).
Short answer: No.
Thanks everybody for posting : )
