I'm not sure how much potential for difficulty this has, but I thought I'd throw it out and see if people can make interesting ones.
The puzzle involves a chessboard that contains:
-One white piece
-One black king
-Some other black pieces
The white piece moves around the board capturing things, and acquiring the properties of whatever it has just captured. It wants to capture the black king.
One puzzle might look like this:
Here the solution would be to capture the bishop, then the rook and finally the king.
Here's a (hopefully) harder one:
Why did the vector cross the road?
It wanted to be normal.
Bd1 takes Rh5,
Rh5 takes Nd5,
Nd5 takes Ne3,
Ne3 takes Rc4,
Rc4 takes Ra4,
Ra4 takes Ba2,
Ba2 takes Kf7!
I like your idea mathsy!
Seems like one piece Hits another piece and Pushes it!
If two or more thoughts intersect with each other, then there has to be a point.
