I always use the term “discovered” as opposed to “revealed”, but I kind of like revealed better.
I highly recommend using reveals, and also pins. They are almost the same thing. Basically, imagine that you have a bishop placed to attack the King, except there is a pawn in its normal starting position that is blocking the bishop’s attack, so that the opponent is not currently in check. When in this position, you are free to move any other piece into a square that would normally be protected by that pawn, because it is pinned by your bishop. It cannot take your piece, because that would open the King up to being in check from the bishop.
Even better than reveals and pins are forks. This is when one of your pieces is either a) not in danger, or b) protected by a weaker piece, and also has a direct attack against two different pieces. When you land this, your opponent must choose which piece to save, leaving the other to be your bitch. For examples of classic pins, set up the normal starting positions, and just put a rook in the opponents pawn row, directly in front of the queen-side bishop. Notice that this knight has a fork on the king and rook, and since you have to get out of check, it is a free shot at the (5 point) rook with your (3 point) knight. If the queen happens to be two spaces in front of the king, then you have a triple fork against the king, queen, and rook, which is affectionately known to me as a royal fork. Anyway, identify good fork attack positions against the normal starting positions, and try to get your pieces to them for quick forks.
The center squares, obviously, are very important. More important than the center squares are all lines that go through the center squares. If you find yourself without any good moves, instead of just advancing a pawn for the sake of it, try moving a bishop so that it cuts across the center squares.
My basic strategy advice to you would be as follows:
-
Develop (or learn) your opening book that will allow you to castle in as few moves as possible, while still getting some kind of presence (usually pawns) attacking the center squares. In other words, always castle as soon as reasonably possible.
-
Once castled, attack with waves of pieces. Queens coming out early is a fine tactic, but she must have a bishop or a knight to help her out. Two bishops is an excellent group to attack with as well, and two knights can be effective. Three pieces can be devastating, but you run the risk of making things so complicated you lose track of what you’re trying to do, and end up accidently losing pieces because of it. So stick to two piece attacks, using pawn backups as necessary, and attempt to set up pins, reveals, and forks.
Pins are the easiest, forks the next, and reveals are the hardest. One tip: when you set a pin, you can safely ignore whatever piece is pinned, but every single move you need to verify that that piece is still, in fact, pinned. Don’t accidently get screwed because you forgot that they castled, removing the pin that was safeguarding your knight.
- Once you’ve sent a couple waves, now start playing for endgame. Since you kept your rooks stationary, (except for when you castled), and because you have “opened” all the bishops, knights, and the queen in various attacks, your rooks are protecting each other. Use this fact to work your pawns with rook support, but don’t lose sight of impending doom for your king.
By “opening” a piece, I mean you moved it off the back row. This advice won’t win you games against good players, but it will get you jump started toward getting a better feel for the game.
As a beginner, I encourage you to memorize the point values for the pieces and make as many fair exchanges as humanly possible as quickly as you can. The moment you can swap a bishop for a knight, or vice versa, or a bishop or knight for the same piece, do it. The logic being that since you aren’t a master yet, you will have a better chance when the board is less crowded.
Good luck. If you wanna play an email game, my addy is in my profile.
