Ignatius is a new chess client for the Mac.
It has nearly every feature BlitzIn, the Chessclub's native windows client, has! And more: premove, a rating tracker, different board styles, completely customizable console, multiple piece sets, a seek table AND graph, and a "buddy list" style notification list!
Ignatius is released under the MIT license. Ignatius is named for Ignatius O'Reily from "Confederacy of Dunces," since I feel like a giant dunce when I play chess.
