Doesn't always replicate moves referenced games.. For example: "Joseph Blackburne vs Hodson 1889, Manchester, mate in 4": the actual correct moves are white pawn to f4, then black bishop xf4, white rook xf4... (afterwhich, black RESIGNS!) however, the app does not follow those moves- which renders the puzzle unsolvable, even if black had not resigned... Look it up, I finally did, after 2 weeks of daily trying to solve it!

@Sir Andinas Blackburne vs Hodgson Mate in 4, is actually Mate in 6. No way that you can mate it in 4. And accdng to some post here, in the actual game after 1 f4 Bxf4 2 Rxf4 Blck resigned, haven't checked the actual game yet though. But it is a Mate in 6.

What's new

v3.0 : small changes to let other apps access to the puzzle database. It will allow plugins like the chessdiags livewallpaper which should be released soon.
