A28 English Opening: Four Knights Variation (1.c4 e5 2.Nc3 Nf6 3.e4 Bc5 4.Nf3 Nc6 5.Be2)

The game below was a rated game but because of the result, neither player lost or gained any rating points because of this game. This game started to go downhill for my opponent when he played 8.d4? which loses both of the important center pawns and after that there is no hope left in White's position. This game was played in rather fast pace for a correspondence game, at least in my standards because this game started April 27th 2015 and it ended May 30th 2015 and these days my average correspondence chess game lasts several months. I have added one mate in one, two mate in two, one mate in three and one mate in four puzzle today.
