Hi everybody, here is a special chess problem. It is a helpmate in 2 and also a special condition: Andernach chess.
Helpmate means that black plays first, and black and white cooperate to mate black.
Andernach chess means that if you capture a piece, the piece you captured with, will turn the other color. Like this: White plays 1.Rxc5=bR. So the rook on c5 turns black. But if he captures with a check, the color still remains the same.
Here is the puzzle: Helpmate in 2
White to move or black to move?
It's not helpmate in one?
It's black to move. It's in the description, but I forgot to set the diagram on black to move... Now it's fixed
Does checkmate count as check?
There is nothing in Andernach Chess that says the piece doesn't change color in the event of a check. Moves like Rc6xa6(=wR)?? are illegal self-checks.
Sol: 1.Rxc5(=wR) Rc4 2.Ka4 Ra3#
are we watching the game from black's side or white's?
1.Rxc5=wR Rc4 2.Ka4 Ra3# is the correct answer!!
are we viewing the board from black's side or white's? can u answer this plz?
White's side, look at the coordinates .
Cheers. I didnt know co-ordinates are always fixed.
