While attempting to use my own strengths, I created a week group and as a result allowed my opponent to create a huge group at the bottom. Of course there may be other systematic error that I do not even realize.

I have gone through the game and made comments (in the attached version, not in the inline version) at various moves.

Thank you in advance.

Hi Degan,

please review for black

You were ; did you want to review for your opp ?

Grabbed the comment-free version off KGS.
General comments up to LL corner fight:
sense of what's big and small, off ;
slow, gote sequences ; making weak groups for yourself:

I'm going to assume that the OP means literally what he said.
The following is a review for black.

Hello EdLee,

Thank you very much for the review. I was white and I appreciate you seeing through my erroneous subject.

You have given me some great things to work on in my next games. I expect I will go through your review more in the future to work on my shape.

I approached what I can see as the small area on the lower right, as I was concerned about not having the chance to invade later. I now see that I must continue to look for and playing into the largest remaining areas. When my opponent made several two space extensions on the fourth line, I thought of that as an overplay, that I would find a weakness to exploit, but my local play was wrong.

First, I will research what is Leela and how to "ask" it.

Thank you,

Degan

Hello Joaz Banbeck,

I appreciate you making a review as well, and following my stated request. I also appreciate that you showed variations for white as well as black.

I will have plenty to try to apply in my next games.

Thank you,

I did not have much trouble. I went to https://senseis.xmp.net and searched for Leela. This game me the link to: https://www.sjeng.org/leela.html where I was able to download a Windows installer, that went smoothly. I loaded this game and went through the moves. It is interesting.

Thanks,

Note that when Ed says "Leela" he means "Leela Zero" (I think). But Leela is good to analyze with too, just not as strong (which is not always a bad thing).
