user1855: In a book from J.Silman, I found this position:
 [FEN "r1qr2k1/p2bppbp/3p2p1/1p1P4/3B1P2/1B3Q1P/PPP3P1/3RR1K1 b - - 0 17"]

 1... Re8 2. c3 h5 *

It deals with the rooks, white managed to semi-open the e column and will deploy a massive attack on it. My question is : why black does not play e7-e5? After dxe6 the white pawn is sufficiently attacked by black's forces, and if there is a global exchange on e6, the weakening of the black's castle does not seem to be dangerous.

user4362: It seems to me that after e5 and exchanges on e6 and g7 the d6-pawn is hanging ...
