I am interested in playing correspondence chess online through the ICCF. It is my understanding that using computers is not only allowed, but almost mandatory. My question is: What all kinds of software are needed to be successful, and what are the best software packages to use in each category? I know you need an engine, a database, and some kind of analysis program, but which ones are best? I'd be interested in hearing about both freeware as well as commercial programs.
Thanks for any help! Chris =)
