Not that I expect you to believe me, but there are plenty of excellent endgame books out there without any engine analysis whatsoever. Even if I'm wrong the price for Polgar's book at amazon is outrageous, and if you do find it for free online it's an illegal download, so make sure your anti-virus program is up-to-date and all the important data on your PC is backed up before you begin the download.
