He misplaces pieces and I win!

My second English of the season and I managed a decisive win as Black ... I think that I managed to encourage my opponent to misplace his pieces which led to the victory.
As usual, any comments welcome ...

English Opening leads to a dubious draw ...

Here is this week's club game - an English. I don't know a lot about the strategy behind this opening other than the fact that Botvinnik has pioneered some sound theory on it ... I need to look this up! (I may even have gone wrong on move 2 ??) I thought I had the edge throughout the game, however a draw was agreed on move 38 after Kf8.
