Thrillerfan, as someone has already pointed out in this thread, there are several ways to decline the Benko. Yermolinsky recommended one simple method in Road to Chess Improvement, and top GMs have used several different Benko Declined lines.
I do think the best correspondence lines against the Benko are in the Accepted variation, but there are plenty of practical ways to play against it that give white every chance of scoring a full point.
No less an opening guru than Vladimir Kramnik as even tried 4.Nd2!?
I beg to differ. Declining the Benko is useless for White. The problem line for Black is the Fianchetto Variation. White should ALWAYS accept the pawn in the Benko.
Nonsense.
Uhm, I trust a Benko guru over some IM Patzer that can't say anything more than "nonsense".
Sergey Kasparov even says it himself in a book he wrote for Black, around the conclusion area of his book. Black has absolutely no problems what-so-ever in lines where White declines the pawn, and the line that gives Black problems these days (book was written late 2012) is the Fianchetto Variation, and if you go thru the book, it's one of the few chapters where White scores quite well.
I also seem to recall in another post that this IM Patzer didn't even know that 1.e4 e5 2.Nf3 Nf6 3.Nxe5 Nxe4 drops a pawn for Black. Therefore, his "nonsense" comment is NONSENSE!
