Practice your Visualization Skills ... It is the ability to see "in your head" what your future chess position might look like.
Chess board visualization training is necessary in order to not miss tactics, see more combinations and to become a better overall chess player. Chess board visualization does not come naturally to all chess players. Chess visualization is something that must be trained, and should be part of a regular chess training regimen.
Chess board visualization training will improve your ability to calculate long variations. Visualization training should take place 3-4 times per week in 5-10 minute sessions.
Are you able to see blindfold the path of a Knight located in b2 to check opponent's King in d4 without passing through the squares where it could be captured by the King?
Are you able to replay the game you just played without looking at your score sheet?
A Candidate Master does that immediately, an expert can do it slowly, most intermediate players have great difficulties, a novice does not see anything.
Knowledge and skill are not synonymous, even if the first is usually an assumption to the second, but is not enough: if you still leave (or even put) a piece en prise, a 101st book beside the 100 you already have will not be very useful.
If the answer to the above question is positive, this training manual is too easy for you, read my book about Visualization, harder to follow.
Otherwise it could improve the way you manage your Knight, a piece which should be moved with utmost care and speed.
At the end of the reading, you will know where to put your King when being checked by a Knight, not to be harassed for four moves.
While the other books I published are trying to share knowledge, this one is aimed at improving your skill.
My students, expecially my senior ones, initially had problems identifying precicely and fast the path of a Knight to reach a chosen position.
De La Maza in his book for adult beginners, and the official manual of Italian Chess Federation strongly suggest the following exercise:
On an empty chessboard (it could be the above diagram on your Kindle), put a Knight on a1. Move the Knight to go to b1.
Now, bringing back the Knight to a1 each time, go to all the squares, counterclockwise and spiral wise. That is a1 c1, a1 c2, and so on till you covered all the squares, up to the central squares.
Do not try to find all the possible ways to reach a square, one is enough.
Note your TIME, using the features of your Kindle to create a note, for comparison next time. You should aim to do the complete tour in less than five minutes.
For a beginner at his first try, twenty minutes to complete the tour would be a success, getting better after some training. The target should be to do it in less than five minutes. Training as directed will allow to reach this.
It is suggested to do it before a tournament.
You can see here a sequence for all the squares beginning from a1, a move per page, and come back with a link at the end of each rank. A total of about 200 moves. No chessboard is needed, nor an internet connection.
The price is kept to a low 0.99, and at the end you will find some way to use your Knight.
Which is not so immediate, as modern directions are to keep the Bishops pair, while in ninetieth century the players were very skilled to use a pair of Knights, they can do suddendly thinks you failed to foresee, to let you wonder how this happened. Remember Legal's mate.
To do the following exercises before a tournament, means to train like a pianist doing...
