O-O 9.Be2 Nc6 10.d5 Ne5 11.Nxe5 Bxe5 12.Rb3 {This line (discussed in 
CBM72) is gradually gaining popularity. The crucial thing is whether this 
rook will be able to take active part in the game. In my opinion, White 
can't do now without c3-c4.} 12...Qc7 {With the text move Black takes the 
f4 square under control, prevents White's castling and prepares ...c5-c4 
at the same time.}

for Black's important dark-squared bishop but complete his development and
then attack the weakened black king. However, Black finds a nice 
refutation.} 18...Rad8! {Again preventing White's castling, this time by
