First chess book I ever owned, something by Euwe. Don't remember the exact name, but it was a rather general beginners book. Probably the only chess book I ever really studied thoroughly from beginning to end. Took me in a few months from losing to just about anyone, to beating all comers, including some ranked players, in my favorite pub.

Kama Sutra - showed me how to dominate my opponent.

Bobby Fischer Teaches Chess.  It's not a high level book, but it teaches a player to think about driving for mate and how to force mate...first, second, and always ;).  Openings, middle game positioning, and endgames are secondary.  Nobody else seems to come at things from this point of view.  The "solve puzzles" format also has a big appeal to a chessplayer's mind.

I read it when I was 7, and it far and away had a bigger impact on my chess play than any other book since ;).

At the moment, I'd say Seirawan's Winning Chess Tactics.  I'm currently reading some strategy books and I hope those make a big impact.

Sorry, but I don't mate and tell

I'd say Dvoretsky's Endgame Manual.  I certainly didn't retain even half that material, but it took my endgame skill from very poor to passable.  The great thing about endgame positions is the text variations are so much easier to visualize... so if only for visualization practice I got a lot of use out of it.

for me was only one book , was the openning book of Kings Gambit , is reason why i wanted to try play hss again, could i play a good kings gambit game and i hae enjoyed many an hour playing finding ou yes i can play a prety god kg game :) rofl.

Which King's Gambit book, who was the author?

This thread is old, but I am surprised nobody mentioned the Road to Chess Improvement.
