What is the best way to get games for the multiple editions of The Week In Chess? I am looking for getting all games played in 2013 as quickly and painlessly as possible. A batch file to download many ziped pgn files would be non-ideal, but ok. I prefer the Week in Chess as a source due to their high DB consistency quality, but the ultimate goal is to compile a single high quality DB of all games played in the year 2013.
Here is your requested zip:  2013_TWIC.zip

I created a command script for this. See attached. I assumed you are running
Windows, but the script is easily adapted to other OSes. 

For downloading, it uses curl. You can get that at http://curl.haxx.se/download.html, and
for Windows, I recommend the msi installer.

For unzipping, I used Java's Jar tool, which is free. But use whatever you
prefer. 

When running the script, run dos shell as Administrator in Win8 or Win7. 
At the end of the script it puts all PGNs into one large PGN file called 2013_TWIC.pgn
HTH.
