Free Game Analysis!

Just a comment about the game I posted about a week ago.
I have two main concerns:
- How to find the crucial points in a position.
- How to keep an advantage like this.
I know about the blunder in move 26, and also some other mistakes (computer analysis), but what I'm particularly interested in is how to identify beforehand the crucial points in basically won position like this. I might have been a bit sloppy when playing this, and this being a 3 day, I should really have looked at the position more closely, and not just played the "obvious" moves.

A number of requests have been made for an explanation of how to post games and this video I made will tell you how

Btw this is animegrime201501 couldnt get into that account so using this one... I am black in this game. Also I have been told at move 30 white had a completely winning position.. can you possibly show how white wins and why... and explain where white went wrong.

Hi everyone, I thought it time to revive this thread since I'm making videos again. Also I plan to start streaming from now on as well
I hope you will actually look at my games and actually help me out.. instead of the abuse i have had to put up with lately every time i post games on these forums...
I'm sorry to hear that, can't everyone just try to get along? We all have the same goal right? Improve our chess... Don't worry I will take a look at one of your games, as you probably read I just got back and will try to get to it soon.
