You shouldn't have played 50...g6+, it took your game away completely 50...Ke7 would have perhaps drawn the game.

There are a lot of blunders in that game- just like my games. 

You hung your bishop... : (

Is it just me, or did you hang your bishop on move 30???? I do apologise if I have missed something obvious!

Yeah, it is a shame you lost. It appears you must have been better at some moments during the game.
