## A Few Chess Problems

A friend recently gave me this problem: Place all eight of white's (or black's) pieces on a chessboard so that none could capture another. (The two bishops must control different colored squares.) Click here for a solution: Here

That task seemed too easy. Let's throw in all eight pawns as well. Now create a position using all sixteen of white's forces so that nothing could capture anything else. Click here for a solution: Here

Of course, it would not be a chess game without at least the black king on the board with all of white's pieces and pawns. I haven't solved that problem yet. To do so with a legal position seems a good challenge. A "legal position" is one which could have been arrived at in a real chess game, albeit with a lot of cooperation by the losing side!

Returning to the first problem above, now try adding two more bishops. With four bishops, two must control black squares and the other two must control white squares. Click here for a solution: Here

Let's toss in another two bishops and a knight. Click here for a solution: Here

A more famous challenge is to place eight queens on the board so that none can capture another. Click here for a solution: Here

Could this problem be solved mathematically? A tantalizing thought.

Here is a problem of a different sort which I created for the Florida State University Chess Club in 1978. It was turned into a design and printed onto T-shirts for the club. The chess position was printed on the front. On the back were the words, "Mate on the Move." It is white's move and he can deliver checkmate immediately. What I am proud of is that the position is not only legal and the material nearly even, it is also not implausible; i.e., it looks like a real game position. If you are unable to solve it, then you are not familiar with all the rules governing the movement of chess pieces!
