The source code for the Stockfish app is freely available, and it was quite useful as a pedagogical tool for me when I designed CBase, but there are still some issues with trying to integrate the engine into my code, with the main sticking point being that I designed my code to allow for variations and thus am using completely different classes than Tord does.  I would have to write a lot of wrapper classes to use his code. 

There is a Stocfish app, perhaps Tord will give you the sourcecode for the app as well as the engine itself?

I've thought about it (I think finding a way to incorporate Stockfish would be amazing) but I'm not sure if I have the programming ability to do it at this point.

Thanks for a great app.
Is it possible to add a open source chess engine so that you can analyze positions?

Great app, thank you! 

Would love to see a next game in pgn button ->> rather than returning to menu and selecting it.

Tactics pgn shows board set up in start position not set up in the problem position.

@johnny-c Another great site to snag pgn files is http://www.chessgames.com/

Awesome work!! Mr. Green...my pocket now is full of pgn's that i can easily view in a second or 2...I have been waiting its approval since you announced it several days ago...Whhhhoooa! thank you very much Mr. Green!...Godspeed!

The program ships with a very small annotated database. I got most of my pgn databases for testing the app from http://www.pgnmentor.com/files.html . Unfortunately the files are zipped, so you'll have to unzip them on a computer first and either transfer them via iTunes or through mail or dropbox. I would like to add support for TWIC and quite possibly zipped PGN files in general. At the moment I don't have plans to make an iPad specific version. I'm about to start grad school and will find my time stretched pretty thin. That being said, it is possible that I will try to write some specifically for the iPad later in the semester, but definitely not until it gets ios 4.

@ JohnnyC - there is a very small database of annotated games included in the app, but there are collections of pgn games everywhere on the internet.

The latest top level games are always available from The Week In Chess.

So does this have a database of games included in the app? Or do you need to download one seperately? (And if so, could somebody please reccomend a good free site?)

Thanks guys! Congrats on the app.

Congrats! Any plan to make it an iPad app? I'll put my money where my mouth is on that idea.

nice job buddy !   congrats on the acceptance and best of wishes for the future too.  Now get back to school young man ! lol

@jhbchess,

It was designed for IOS4 only so you can't even download it for the iPad. I suppose f you jail broke your iPad it would work.

Thanks Austen, I hadn't spotted that.

Thanks for all your efforts on this great app!

@ SonOfPearl: On the page where it says "Unable to View File," there's an icon on the toolbar which looks like the mail forwarding icon.  Touch the icon and it will bring up the option to open it in CBase Chess.

@ Manack: I'm already working on FEN support and I am working on finding the best way to implement a broader range of tag searches.

Wow it got approved fast! I shall try this app out

Very nice, already one of the better pgn viewers available. 

I really like the variation support, comments and being able to import a pgn from the web so easily.  The interface is great.  The two additions I'd like to see is:

1. FEN support
2. Games searchable/filterable by many more tags.  I often want to see a list of games with players above a particular rating of a certain ECO code where a particular side wins.
3. Ability to move the pieces and try out some variations and then reset it back to the position where I was before I started moving.

@NM ajgreen - I opened a pgn database from a web link with no problem, but when I saved the same database, put it in my dropbox, and clicked on the file from there it wouldn't open.  I get the message "Unable to view file. This type of file can't be viewed."

I'm using the latest pgn file from the NH tournament on the TWIC website if that helps.

@SonOfPearl: Having to scroll for the "Open in CBase Chess" in Safari is something weird that Safari does - unfortunately I don't have any control over how it places the button!  What kind of problem did you have with the file from Dropbox?  If you're trying to open a file that was input by hand (as opposed to produced by another chess software program), it probably doesn't conform to the PGN protocol, and CBase won't be able to read it properly.

Nice job!

I clicked a pgn link on a website and at first I didn't think it had done anything - then I noticed that I could scroll to the right and there was a button to "Open in "CBase Chess".  If you could avoid users needing to scroll that would be good because it's easy to miss otherwise.

I also tried opening a pgn file that I had put into my Dropbox app, but that didn't work for some reason.
