Analysis Tool

I just created an alpha version of an analysis tool I was thinking about.

https://chess-analyzer.azurewebsites.net/index.html

It is still in early stage and only checks the archives for standard games, but I find it already more usable than the chess.com archive search...

For now,  you get an overview of your games played during the selected month, which you can quickly filter and chart.

Feel free to comment/remark/suggest

Nice work. 

When I click on the game link it opens the game in a new tab as expected but when I go back to the game list I get an error...

This happens in Firefox and not in chrome.

Very nice!

-----------------------------

• Maybe have the default chart view be By Opening as it is the more interesting one.
• It would be cool if the ECO opening tables were live links to Chess.com's opening explorer.
  
• Adjusting the column widths to permit more characters for the opening would be nice.
  
  Don't know if the info is easily available but:
  
  
• Adding a column for # moves would be nice.
• Adding CAPS Accuracy numbers would also be nice.

--------------------
The Year increment/decrement works on an empty field permitting negative numbers. Maybe default to the current year. If easy don't increment past the current year.

Pre-fill the User Name, Month and Year with the current values to make adjusting the query easier.

@Hyper-Dragon: Fixed the FF window.open

@jas0501:  great suggestions to improve ux, should be easily implemented.

I'm currently working on the analysis of the moves, but that will need some more work...

You have indeed, that was quick!

Just one other thing...It is saying that (as white) my most played opening is the 'Amazon Attack' but I had to look it up as I have never played it. (BTW the ECO code is correct)

yeah, chess.com only provides the eco code and a link to their website, no api involved there. I found a list of eco codes online and used that to map the names to the code.

When you go to your game in the archive, does it also mention 'Amazon Attack' or just 'Queen's Pawn'?

It doesn't mention the Amazon Attack (which is 1.d4 d5 2.Qd3 not 1.d4 d5 2.Bf4)

If you want to make life easier  you could always extract the names from the [ECOUrl] in the Pgn.  Just drop the "https://www.chess.com/openings/" part and replace the "-".

One more UI suggestion:
On the chart have a tool tip on hover over the ECO. Or maybe better since not all Bars are labeled, have the current tool tip include the Opening Name. So instead of:
this:

Though something like

gets a bit looooong.

This is great! I've been meaning to ask about a tool that will let me categorize my games by opening and even at this early stage this tool does the job.

I'd really like to view all of my games together, or a years worth of data, instead of looking at just a month's worth of games at a time.

It would also be fantastic if I could filter the data by opponent rating. I usually play players at my skill level but occasionally I play much stronger players. When I play the much stronger players I am not playing to win as much as trying to learn new ideas from better players, so I wouldn't want those games to skew the figures.

I found a couple of bugs.

I played two games recently featuring the Latvian Gambit. They are mis-categorized as the Elephant Gambit.

I played a game starting 1. d4 e5 and this is mis-categorized as the Australian defence.

@KevinOSh Thanks for the feedback. I'll add the rating and the time range. 

The ECO names are indeed an issue,  I'm looking into it. Seems that the list I'm using is either outdated or just wrong.
