In the history of chess good books were written and strong analysis was usually provided by very strong players. In fact for many older GMs that was their main source of income. With the appearence of chess engines all of this has changed. Even lower rated players can come to correct conclusions by simply clicking through variations with their engines. I can name two examples: Kris Littlejohn and Nikolaos Ntirlis. The first guy is Nakamuras assistant, the other guy (no joke) worked as opening coach for the danish national team and has written a few books. Why does this work apparently well enough? The answer is simple: The guy is just the messenger, while the message itsself comes from some silicone-monster rated 3600+. Obviously I am trying to make a case for the “Expert Patzer”, because I am one of these myself, but there is something to it. With the help of strong engines even amateurs can come to totally valid conclusions, and if the engine-line ends in a forced repetition the game is finished after all. There is nothing more left to prove, not even good endgame technique. If the line does not end in a repetition though some care is neccessary, because new generations of engines produce better lines. Most of the analysis on this page is already more than five years old, before neuronal nets were available. Double-check everything!
