2) On move 11 when he played Bg4 you could play Bxf6 and win a piece by either ....Qxf6 Qxg4 or Qxd1 Bxd8 Rxd8 Rxd1 which would have left you an exchange and two pawns up.Ah! I must have panicked with the attack on my queen and failed completely to notice this. I would in any case exclude the first pawn from the "swap", as I wouldn't have swapped if black hadn't attacked my knight. At least I hadn't considered it until then. Thanks for the comment.
