2) black pawn at f3 moves to e2 - queen to b7
3) black knight moves to d2 - king takes black knight
4) black knight moves to a3 - king castles with rook

Re: Chess puzzle
I think you are misunderstanding.
The first white move is queen to B2. The second white move is dependent on which piece the black player moved. One pawn can't move at all, one can only move to one position, the knight can only move to two and the rook can do what it wants.
Basically, once the queen moves to B2 it matters not what the black player does - all four options result in mate in the following turn.

Re: Chess puzzle
If I move the black rook to C2 how do you get checkmate on your next move?

Re: Chess puzzle
Isn't the above just what I said further up? KendalDave pointed out that the knight can move to B3 and then back again if the King moves up.
Re: Chess puzzle
not 2 moves though is it?
also after king e1 to f1
I move my black king to H2, don't see how you can then checkmate me on your next move by moving to H5 with your rook, I have space to make another move with my black king

Re: Chess puzzle
If the king moves e1 to f1, then the black knight moves b1 to d2 and puts the white king in check. So white has to do something about that and can't move the rook.

Re: Chess puzzle
i can do G5 - H5
Black king can only move 2 places, G1/2
White Bishop to H2
I was thinking next white move regardless of black, C1 to G5, however black could move B1 to D2 before me and more steps required
as I said my brain hurts

Re: Chess puzzle
Then rook moves to d3 or c2 and puts king in check.
Re: Chess puzzle
yes ok, so instead of moving rook I move black pawn to F3 to E2 how does white make checkmate on the next move since the queen is blocked from black rook in moving directly to H8 now.
Re: Chess puzzle
happy to be corrected, but dont think you can castle with knight attacking b1 from a3duncandisorderly wrote: ↑Fri Jun 12, 2020 4:44 pmThere's more than one way I think depending on what the black player does, but the first move is queen to B2.

Re: Chess puzzle
The rules for castling require no pieces betwixt the rook and king and that both pieces are in their original position - if the knight is in a3 then it's no longer between the two - unless I misunderstand you?

EDIT - but there's no info about whether either the king or rook have moved previously so the solution assumes they haven't

Re: Chess puzzle
Black knight moves to A3 - the black knight can then immediately move back to where he was originally, blocking the line of king and rook.

Re: Chess puzzle
By castling the king ends up in c1 and the rook in d1 - by moving the knight back to b1 you are just adjacent to the king - unless I'm misunderstanding what you mean?
Re: Chess puzzle
Now I FINALLY see it lol, queen can go H8 if rook moves, or B7 if pawn moves
but if I move black knight to D2 what can the next move be for checkmate? E1 to D2.
Easy wasn't it
thank you

Re: Chess puzzle
The rules of Chess state that castling is illegal when:
1. The King has moved earlier
2. The Rook has moved earlier
3. The King is in check
4. The King is under an opponent's attack
5. The King's squares of journey and destiny are under hostile attack by an opponent's
piece.
6. If there are Chess pieces between the King or the Rook
If you have been checked during a game and you have met the above rules (i.e. the check was blocked by interposing another piece or by taking the enemy piece with an own piece other than the King or Rook involved in the castling) then nothing will prevent you from castling later.
This applies no matter how many times your King has been put in check during the game.

Re: Chess puzzle
Queen moves to B2.
If we then see B1 to A3, then the king can move to D2.
Check.
The knight in A3 can move back to where it was originally - B1. This then makes the King no longer in check as the knight is blocking the rook.
Both players have played 2 moves.

Re: Chess puzzle
forget the castling, as pointed out, move queen to B2, regardless of what black does next move is checkmate ether by queen, 2 options if black moves rook or pawn. If black moves knight then king takes knight and checkmate from rook A1.

Black knight then uses his second move to go back to the space it was originally in. Doesn't this block the check?
Not played chess in years, but thought rook - knight - king, means the rook is no longer putting the king into check.

Kate - if the black knight moves to A3 then the only way to win on whites second turn is by castling.

yes sorry, seeing that now, was missing the A3 move doh! So there are 4 options for the check mate for the 4 potential moves black can make, that penny is dropping slowly but hoepfully that is the end of it
