Black chooses to move the Kt twice to free up the c-pawn rather than Bd6 to reinforce the potential pawn break e5. In view of the Fritz8 analysis given after 10..Bd6, it might be the "lesser of two evils". [10...Bd6

Not a necessary precautionary move since White can proceed directly with his attack down the half-open g-file. His two bishops are compensation for his doubled f-pawns along with the half-open file for which to place his rook. [13.Kh1
