A simple but elegant chess variant

It is a variant of chess that can be played on a normal chessboard and with normal and ordinary pieces ... except with the exception that two new pieces are added per player.

Joker:

You may know this piece, yet I will explain it. The joker, jester or fool is a piece that mimics the movements of the piece previously moved by the opponent.

For example, if the opponent moves a queen, you will be able to move the joker like a queen. If the opponent moves a horse, you will be able to move the joker as a horse. If the opponent moves his joker, you can move your joker as the piece that the opponent's joker imitated. ETC.

However the joker can not copy attributes such as castling, royalty (receive check) or promotion, although it can exert movements as the double step of pawn start and capture in passant, under special conditions.

Wrestler:

The wrestler, masked wrestler or great leaper is a piece of my invention.

Basically it is a piece that can do two things:

1. Capture an opponent adjacent piece (if there is an opponent adjacent piece).

2. Or move to the adjacent square of an opponent piece, leaping directly (to any square arround any opponent piece).

If the wrestler capture a piece, this can next do another extra movement and move to the adjacent square of another opponent piece (in the way I explained before, in 2.).  It can't capture two times in the same turn.

When are these pieces added to the board?

Each player has one joker and one wrestler. However, these two pieces are saved out of the board until a player decides put one of these in the board.

You can put then the joker or/and the wrestler in the first row (respectivelly to you), ie, the row of not-pawn pieces.

Put the wrestler or the joker in the board will consume the turn.
