Effective Visualization Training

The Chess Eye software I found surprisingly helpful as a first start.  It's free for the first seven or so exercises, and then if you like it you can pay for full access.

At first I thought it was useless, but the more I used it, the better I could picture a board with my eyes closed, and soon I was able to put pieces on the board and remember where they were.  I can now play through short, simple games in my head, though blindfold remains out of reach.  My goal is to eventually be able to read chess books without needing a board.  Someday.

Anyway, google 'Chess Eye software' and it should be one of the first links.

 White to move and win

Yes there are. Its the blindfold pieces. There's a mate in one.

1.Nf7+ Kg8 2.Nh6+ Kh8 3.Qg8+ Rxg8 4.Nf7# It's easy!

If I told you, the magic would be gone...

     Endgames is the best visualisation exercise according to both Dvoretsky and Aaagard.Start from the simple ones and go all the way up to the more complicated. 

     You take a good book and a physical board.You put the position on the board , you read what the author sasy and you are sure that you understand it.Then try to see the lines in your mind.Right them in a paper(usually that helps)if necessary.To be sure that you saw the line correct continue your calculation 2-3 moves after the line ends(write down the moves).Then play the line on the board.Did you calculate everything correct?If yes , move on.If not, you can move on but you have to return in this position.

     Examine moves that the author doesn't mention and be sure that you can see the winning line .Even in the most simple positions authors don't mention every move because they assume you understand the technique and you can find the rest on your own.

     Overall , good book , physical board , pen and paper, a lot of personal work and most important of all , no distractions(uninterrupted concentration).Your ability to stay focused during your study will determine whether you are capable of improving or not. 

It is because you're on mobile?

Man, I can see this is really getting to you. :)

It's pretty simple. Just view the page source (html). Search for the word "fen", and you'll see the FEN string.

For me I did it differently.

Look at the diagram in post 5 again. At the bottom left there is a mini chess board. Click on it and one line of Stockfish analysis (the best available move for the player having the move, and the line following that move for a few moves) will be available just above the original diagram. Along that analysis line, there is another mini chessboard on the right-side. Click on it, and the full Stockfish analysis will be available, and the diagram on that Stockfish page will show the 'mystery' pieces (together with the top three preferred moves and their subsequent lines).
