To be fair, I've seen that one before.
I love chess, by the way. If anyone ever wants to play a friendly correspondence game you can find me on
QueenAlice.com (I'm Narz on there too).
That's it! Narz is a genius!
I always liked that one. I love chess too but I only play at around a 1500 level and I can't seem to push it much beyond that. I might be interested in playing a correspondence game with you.
If anyone's interested, you can download Winboard free here:

It's what I used to set up the chess puzzle above. (I used SnagIt! to create the .jpg). I like it better than some of the other computer chess boards out there because you can easily set up puzzles, positions, etc. and have chess engines play them from there. The other boards don't seem to allow you to set up positions and have the chess programs play them - they always force the engines to begin each game new.
If you download Winboard, get this little handy program too:
http://home.pacific.net.au/~tommyinoz/tomsengman.html
It's called EngMan.exe for Engine Manager. It just makes adding chess engines to WinBoard really easy so you don't have to bother with setting up the .ini file in Winboard yourself.
Then, you can get all sorts of chess engines from here:

Look around for one you like in the playing strength category you want. If you want a really good engine for analysis, I like Ruffian. Man, that program plays really intelligently. It probably plays at 2600 or above depending on the system it's on and how much time you give it to ponder.
Chess engines are useful for many reasons. Suppose you are playing someone who always opens the same damn way every time. Well, you can set up the typical opening moves that you are encountering with this player and have the engine play through them so you can see what a grandmaster would do and why. Some human players use gambits in the opening for example - a chess engine with Ruffian's playing strength will maul a gambit player badly.
When I'm analyzing a position, I'll try playing Ruffian against Abrok which also plays a really strong game, or I'll use Sharper which plays at around 2000 playing strength. This is often more useful because the really strong programs are considering patterns of play that are beyond most people's ability to see - so extremely strong chess play is often nearly impossible to understand!
The Crafty chess engine is the perennial favorite of people interested in chess programs because it has been the labor of love of computer science professor, Bob Hyatt, for years now and he makes the source code available for free. It plays a really strong game but Ruffian will usually kick it's ass. It was adapted from the original Cray Blitz which played on the Cray supercomputer in the early 80's.
Once you get Winboard installed and a few engines working in it, you can download Fred Reinfeld's "1001 Chess Tactics" from here:
http://www.chessville.com/downloads/dow ... rcises.htm
(get the big file at the bottom)
There are four things to focus on in chess:
1. Tactics
2. Tactics
3. Tactics
4. Openings
"1001 Chess Tactics" will help you with the first three!
What you can do for fun is get a position from "1001 Chess Tactics" and play it against a chess engine all the way trough to checkmate. But beware! Really strong engines like Ruffian will often beat the pants off you even when you successfully figure out the chess puzzle and continue playing at a strong advantage!
But it's a good way to practice skills and it's pretty fun.
Totally mentally absorbing, I think.
Here's a typical puzzle I picked at random from "1001 Chess Tactics":

There's an imporant tactical move that would be obvious to a chess master but might not be to we ordinary mortals. You could play this position against a chess computer and fudge and fumble around til you get it. But even if you as a novice player find the right move, there's a good chance that Ruffian or one of the other really strong programs would just walk all over you anyway!
