I've heard of this feature on chess.com, and I'm interested in using it, but I don't know how.

It's the Explorer. https://www.chess.com/explorer?gameSource=own&gameType=all&color=white

Do you need a paid membership?

Perhaps.

Pretty sure all members have access to all of their own games in Explorer.

It's naturally limited when there are a limited number of games 

But chessbase also provides those cheap win/ loss/draw statistics by ECO line.

What magic info do you get with your magic database?

So you haven't actually used anything else, but felt compelled to denigrate what is here.

I find it useful. I think it's one of the best features here.

I used to play correspondence/ daily chess and found databases like chessbase very useful in trying to make a good position. They obviously have bigger/ more up to date databases of games to study than are available here.

However, the ability to look at your own games is something else. Finding lines you consistently win or lose is very useful.

Denigrate. Since you can't spell it, I presume you don't know what it means.

verb (used with object), den·i·grat·ed,den·i·grat·ing.

ORIGIN OF DENIGRATE

SYNONYM STUDY

I told my friend that I posted on my favorite chess website's forum for the first time, and I told him about all the comments that my post was getting. I told him that someone copied and pasted a dictionary entry, and he said, "I hate that kind of person. I want to go on record saying that."

Well thank your friend for going on record through you. He didn't say if I was correct or not but just denigrated my attempt to decry what I perceived to be a thoughtless attack by someone who hadn't even bothered to try out the Explorer function.  

Just because someone made an error in the spelling does not mean he does not know the meaning of that word. Please don't act like you are someone superior. 

I didn't. It was only after he explained that he hadn't tried it or competing products that I characterized his original response as denigrating. Since I explained all that, and he misspelled the word, and asked for an explanation, I thought he might not know what it meant.

I didn't say the stats were cheap. Those are your words and they are denigrating. 

I said that for the purpose of looking at your own games, the Explorer can be very valuable. I hope you will give it a try after you have played more than 20 games.

I was just quoting you. Sorry, I should have used quote marks. I don't think that the stats provided here are cheap. They make logical sense to me. They are the same stats one sees elsewhere.

I thought I did explain that by focusing on an ECO line and looking at the won/loss/draw stats, one can see where there are likely problems in an opening repertoire. The people who play the Queens Gambit Accepted, the example I showed, who try to keep the pawn, have horrible results.  If I played the Queen's Gambit Accepted, I would investigate.

They are a place to start. When you see a line that has abnormally good or bad results, it is a place to examine and determine why.  Comparing them to a larger sample database is a good place to look. In the case of the Queen's Gambit Accepted line where black tries to hold the pawn, it is a well known trap.

For my account it says "Upgrade to Premium to explore your own games" in Explorer when I want to check my own games. So its not really available for all members. Do I need to have Premium membership to access my own games in Explorer?

if you want to get past move 5 you need to have at least a gold membership

Our you can use Opening Tree

yeah I can"t I am not paying for a premium membership
