It's so horrible and such a torture . Firstly he chooses mostly safer lines , for example between an option of a pawn push on the queenside or Kingside he will chose queenside ,so basically if your below 2300 Fide and trying to get a repertoire on KID this is a complete waste of time yoy will know lines that you won't require cuz neither will your opponent and the game still might most probably end in a draw or white outplayed you even if he's tiny bit higher rated ,50 percent of the positions will reach a 2 result nature , either draw or white wins , with more possibility of black holding , but then I ask ,WHY AM I PLAYING THE KINGS INDIAN and not some QGD Lasker variation.
But that's the least of the readers' worry, I have a game open in my database currently , between Tudor Ristea(2416) - Jose Maria Lanz Calavia (2385) . It seems poor Jose bought the whole series and spent a lot of time getting the tonnes of lines down in his head , and when he finally got to play the line given in Mar del plata1, on page 40 ,under the chapter 10.Nd3 11.f3 , he followed the line just as given in the book for 21 moves!
On move 22 however , it seems White has also got the lines from the Kotronias books and actually checked them with the engine,
He did not play the move 22. Bc4 which is the only line given in the book , but he rather played 22.Bd2 which is engines top choice and the eval after that move is +1.7 ! And guess what 22.Bc4 ISN'T EVEN IN TOP 5 of engines choice.
That's horrible work from GM Kotronias it's his fault that poor 2385 having worked so hard as it's a mammoth collection of lines in 5 books still was playing a +1.7 position on move 22 and didn't even know anything about the objective eval of that position cuz he wasn't even warned .
The reason I am so angry is because I have invested 10 hours each day for the past 20 days on the series and it seems now this is one of the worst project ever by otherwise a really great publishing company by one of my favorite chess book man Mr.Aagaard.
