What strange chess rules can you think up?

Can not spit on the board

if anyone ever plaks this, i think you might want to know that the K is worth about 4. so this is a skewer, not an absolute pin:

Very strange... excellent suggestion!

How about Strip Chess, when you get checked you have to remove a piece of clothing. The strategy for male on male and male on female would be worlds apart.

A perv answer for sure.

All right! It's Wiener Head himself.

Call me sir!

Okay sorry, Sir Wiener Head.

No, sir stands for

Superior Indubitable Runt!

Alright Weiner Head I'll stand back while you insult yourself.

It's not an insult at all, I am comfortable in my own skin (and height)!

You are just against little people, thus you possess a small brain.

I came up with a version of chess a while ago, and this has made me remember it.

One side can choose to have their pawns behave as queens, thus having 9 queens to start with.

However, the other side gets the ability to resurrect any of their taken pieces. The resurrected piece can be placed anywhere on the board, but cannot cause check or checkmate, and placing the piece counts as a turn.

I have actually played this, and it is very interesting. The side with 9 queens gets the obvious opening advantage, but if they do not attack swiftly, the advantage turns towards black.

There should be 8 random poisoned squares on the board, which players know of. If they put a piece there by accident the piece is vanished into thin air.

Each piece, besides the pawns, in addition to its original move, may move as a king that's not subject to check! Now the knight is REALLY powerful...

The one that I've proposed before is that you can promote to King if you want.  If you do, you are allowed to leave one of your two kings in check, but never both.  To lose, BOTH of your King's must be checkmated at the same time.

Therefore, if I promote to King, and I have a King on a8 and another on g1, Black goes Qb8 (with his Knight on d7, protecting the Queen), then in essence, that King is checkmated, but my other one isn't, and if he moves the Queen off, the a8-king is back to life.  If I say, trade Queens on b8, I get him out of checkmate, so promoting to King is going to make winning for your opponent EXTREMELY difficult, but you may also have trouble mating your opponent with an extra King, whereas an Extra Queen will likely kill him.  If you are about to promote, but so is your opponent, and you promote to Queen, he may decide to promote to King.  You have an extra Queen, he has an extra King you have to mate!.

Adds a twist to decision making, and definitely adds to the value of promoting a pawn!

Imagine this stalemate after 2 promotions to King by White:  BKa5, WKb7, WKc4, WKa3

You first start with normal pieces.

Then, pawns can only promote to knights.

Then, here's the variation: If a queen, rook, or bishop gets to the 7th or 8th rank for white, 1st or 2nd for black, they have to change the piece to anything but a queen. Then, if the newly promoted piece gets back to the 7th or 8th rank for black, 1st or 2nd for white, then it has to change pieces AGAIN.

The second idea I once had was called "Wraparound Chess".  Your pieces can wrap around the sides of the board, but not the front and back as the King's would be in check at the start of the game.

Therefore, note the following items:

After 1.c3 or 1.c4, Black can't move his f-pawn as he'd be in Check (Qd1-c2-b3-a4-h5-g6-f7-e8)

After 1.g3 or 1.g4, Black can't move his d-pawn as he'd be in Check (Bf1-g2-h3-a4-b5-c6-d7-e8)

If White opens with his d- or f-pawn, Black can put White in Check on move 1.

The Rooks start off the game connected!

Wrapping around applies to all pieces.  Kh1-a1, Ng1-a2, Bf1-c6, Rh1-a1, and Qd1-a6, are all legal moves!  Even h3xa4 is legal!
