Diagram Testing, Testing, 1-2-3

Continuing with How I Spent My Summer Vacation, any aspiring chess player and/or chess writer needs chess software. I rely on two programs: (1) to manage chess games and (2) to manage chess engines. Until my old laptop started coughing and wheezing, I was happy with (1) the first version of Chessbase Light (CB4?, 1998) and (2) Arena (see Adventures with Arena & Rybka for more about the engines). On my new laptop I quickly discovered that the old version of CBLight no longer worked under Windows 7, while Arena worked without problems. What to do about CBLight?

The most important functions I need to manage chess games are entering moves & variations, entering comments, and creating diagrams. I also have some need to manage databases of games, but as I become increasingly enchanted by chess960, this requirement is becoming less important. After trying a handful of packages, I settled on Scid. It handles chess moves, variations, and comments well enough (although with several annoying quirks), but what about diagrams?

I worked out an appropriate board size, piece style, and color, but what does it looks like in practice? Here is the first diagram I used on this blog, from a post titled C.J.S. Purdy's Correspondence Skullduggery:


Old Version

And here is the same position created using Scid:


New Version

It looks good on my draft HTML page, but how will it look on Blogspot.com?

Later: The new image size is smaller by 10 pixels on each side, but the border for the notation coordinates is a bit too wide. The most important factor is whether the diagram interferes with grasping the position. In this respect, I think it's satisfactory. • One important difference: the old version is a GIF, while the new version is a JPG. GIFs usually look better with line art, but I couldn't get the image software to work correctly. More work needed...

Even later: Here are JPG and GIF versions...

...The JPG version shows distortions around the pieces, the Black Bishop in particular, and the file size is about 60% larger than the GIF. In the future I'll use the GIF version.

Hi

Nice advice! You might also want to try out to use the PNG format and save the image as a 8bit PNG. I tried with your last GIF and was able to reduce the size from 5598 bytes to 2445 bytes. I used Photoshop CS3 "Save for Web and Devices" feature!
