Note that if White takes on d6 (exd6), the pawn d4 remains isolated. However, if Black takes on e5 (dxe5), White gets rid of the need to protect the pawn d4. The d-file will be opened early, while White has some space advantage and better development. Note also that Black's bishop f8 must go to e7 anyway to guard the threat Ng5.} ({Better is} 8...
