English game

I've been playing the English for a few months now.  Not sure if I will continue, I like some things about it.  It can give some fun maneuvering type situations.  On the other hand the opening sometimes feels quite restrictive about what will follow.  e4 definitely seems to give move variety.  Regardless I have had some interesting games, and feel I am learning if nothing else.

The first analysis is by hand. I focused mostly on a position where he already had pressure against my king and I made a move with not much to say for it.  I thought another move in the same position might save me but it seems not. The blunder check analysis shows that I am already lost, though I could defend better than my weak move for sure.

What I did for the IDeA analysis was to put in my hand analysis file and then told the computer to analyze every position.  My thought was that this would be a good way to go through and see what the computer thinks of the analysis I did.  Two things here. First off I haven't had a lot of time to play with it. I think IDeA is best when you really have time to make it interactive and explore.  Also, I did a bad job by putting a pretty messy file into the analysis. Many of my variations are weak or bad even to my own eye reviewing them.  I will try again with my updated file when I have a chance.

Any comments are welcome.
