Hi Chess Friends , I have a question I haven't been able to find an answer to. What are some ways you can improve your chess without a board. Specifically, while im in class just daydreaming XD. I would like to instead maybe do some mental excersises or something. Or how about do something on my Notebook. I don't know, I just really want some ideas so I can further improve my Chess Play and better utilize my time. Thanks for those who reply 

Try to play out the basic mates in your head -- like two rooks vs king.

You can also do knight circuits -- start with the knight on a1 and find the fastest route to b1, then to c1, etc...until you've covered the entire board.

YOUNG MAN. Stay in school! Learn about microbes and kilowats and Ophelia. They will help you get married one day.

I didn't become interested until my last year of high school (luckily?) but I used to draw little chess boards (draw a box and divide in half over and over until you have an 8x8 board) and work knight problems (capture the pawns in fewest number of moves) or compose simple tactics.

Even today, when I'm having a little trouble going to sleep, I do little knight exercises. Think of a starting square--c2 will do. From c2 my knight can go to a3, b4, d4, e3. From a3 I can go c4->e3->d5. From b4 I can go to d5 or d3->e5. From d4 I can go to  . . . Zzzzzzz

This is a great idea, I will definitely try these. But hey are there anyways I  can improve my Chess performance overall. Okay I have the ability to play a full chess game in my head. But, I dont like studying the opening without Houdini teaching me. Is there anything else I can do, because Im really trying to get all the Chess Practice I possibly can in my day.

I heard there was some chess excercise in Czech, where they test for chess ability in youngsters by making them move the knight around the board, without being attacked by pawns on c3, c6, f3 and f6. The knight starts on a1, and must go to every square at least once, except for the pawn squares.

Two minutes and under when doing this is a sign of grandmaster talent apparantly. 

EDIT: I was just posting an exercise to do, you can try and do it without a board, but it is generally done best with the board. The Czech exercise was done with the board when testing. 

The only way to improve your overall performance is to eliminate your weaknesses. The only way to do that is to figure out what weaknesses you have!

Visualization exercises like the ones I mentioned help your calculation ability, but if you can play entire games in your head already it seems you don't need to spend any more time improving that!

It always amazes me how people can visualise a whole chessboard in their heads, I have trouble with 4 squares let alone 64!

Seriously people, how do you do it? Share your wizardry.

Yeah, if you want to play blitz you should really be able to do the basic mates very quickly, otherwise you'll suffer the pain of losing on time in a won position.  I will admit though, that if I had to give mate with a bishop and knight without much time on the clock I'd be in trouble, and probably even with two bishops for that matter.  I once saw a guy pull off the bishop and knight mate in a blitz game with only about 30secs on the clock, that was fairly impressive I thought.

Okay lol , well I was like you. How can it be humanly possible for Paul Morphy to have played 30 Simul blindfold Games! I thought he was a Genius beyond Comprehension, but then it clicked. You have to play Blindfold by Positions, not by Game. Allow me to elaborate.. Have you ever tried looking at a position for 10-15 seconds. Then remove the pieces and put them all back where they were originally. In like manner, you can do this in blindfold. Imagine the move, then memorize the position, you do this for every move. That way just in case your forget what moves were done in the past, you won't forget the initial memorized position in your head. If you practice this over and over . It'll be easy for you to memorize positions. So basically, after you've mastered it, you WILL remember every move thats been done in the Game because youll have memorized every Position. Then, you'll be able to play a full game in your head. Another way is to look at a tactical puzzle such as forced Mate in 2, Mate in 3, memorize it, and then play and figure them out in your head. Now the question how do you visualize a whole chessboard in your head? Im pretty sure every chess player can imagine the initial position of a chess board. The more Chess you play, the more patterns you recognize, Patterns=Placement. Since Ive developed my memorization skills, I know where every piece is. And after seeing the Chess.com 2D Board for so long. I can just imagine the board because I have a picture of it in my head, all I do is add the memorized positions of the pieces. I know it might sound confusing, but with practice you'll understand what I mean. I dont even memorize the colors nor numbers of the Squares. I focus on Piece Placement.  I hope this answers your question.
