C46 3.Nc3: Unusual Black 3rd moves (1.e4 e5 2.Nf3 Nc6 3.Nc3 Bb4 4.Nd5)

The game below was played in the first round of the 2014 October Long Haul Split I tournament that is held at Red Hot Pawn. I am currently on sixth place in group 2 after I have finished half of my games in this round. So far things have gone as well as they can go, because I have won all my 11 games. Because there are 11 more games still to finish, this tournament can still become a disaster for me. Beatlemania leads the group, who has gathered 48 points so far. Blackpoolmad is on second place and has gathered 43 points. Third place holder is blither, who has gathered 40 points. I have really good chances to win the group and advance to the next round because I have six points higher maximum possible score than beatlemania, who currently has the second highest maximum possible score. I have added two mate in ones, one mate in two, one mate in three and one mate in six puzzle today.
