I am really interested in drilling on tactics, but I haven't yet found a way that fits me best.
I have not tried any of the commercial software packages, like CTArt, which may be just what I am looking for, but would like to hear some feedback before purchasing.
Things I have tried thus far have been web sites, mostly:
1) www.improveyourchess.com, which seemed like it was going to be a great site, but the GMs running it just don't seem very interested in the customers.
2) chess.emrald.net, which I actually like a lot, but would like something where I can adjust the complexity and time controls.
What packages have you used, and what did you like/not like about them?
