Advanced Middle Game Attacking Tactics Before I get into the details of my questions, I already know the f, g and h pawn attack tactics, bishops sacrifices such as the greek gift and Lasker's double bishop sacrifice among a few others and of course things such as the isolated queen pawn positions(which is usually something that ends up in the end game part).

So what I am looking for are some advanced middle game tactics, be it from books, online teachers or anything of the sort. I do not have the money to buy the rest of Daniel King's power play series and I already exhausted the few books I have. Any help would be appreciated.
The attacking manual by Jacob Aagaard might be just what you are looking for. I enjoyed it a lot. It contains instructive games and exercises.

Other good books on attacking: Spielmann, The Art of Sacrifice, Vukovic, The Art of Attack,  Christiansen, Storming the barricades.
