Yes, when I tried the analyse mode (192 Mb hash), GT also prefered 13.-Bf5 after the same amount of time that was used in the actual game (between 3-4 minutes I think). Just like in your analysis below. Then I put up the position after black's 11th move and played 12.c4 (192 Mb hash - opponent human. Tiger responded with 12.-d6 and after 13.Qe2 again played 13.-Be6, just like in the game. Hash was cleared between the operations.
