Yeah, good one. Allow me to say, though, that mine is not THAT complicated

 

[BasketCase]

My solution is more readable.

I gave mine first

First is the worst.

Actually Basketcase's is right, as a promoted piece is still the same piece, just a promoted version of it.

You go, basket case!

 

[BasketCase]

Scuse the delay. Real world getting in the way of that which is truly important.

A bit of a different chess puzzle: cut the chessboard below into four pieces of the same size and shape. All cuts must be on the grid lines, and each piece must have one ruby on it (but the ruby can be anywhere on that piece)

I know the answer (I've seen the problem before), but I'm too tired right now to remember it. I may post an answer in the morning, if I remember to.

Done it. Can't be bothered drawing it though.

Spoiler :

draw 4 points spiralling out from the 4 centre squares

And I don't have any more questions either.

64 .

For those that needs clarification, here's a picture.

by cover I mean control (able to move there in one move or are there)

Less than 8 but greater than the amount that I'm willing to find out.

[Syterion]

The answer is 7.

Start at a corner and move as a knight toward the other side the same way each time, and when you can't go more towards the edge, go one row downwards and fill in the columns continuing in the pattern before.

 

[Perfection]

The answer is not 7

 

[Pirate]

I found an answer with 5. (a4, b7, c3, e2, g5)
