Dunno how many chess players there are here, but attached is a pretty tough puzzle. It's white's turn, and he can mate in two moves.

View Full Version : Chess Puzzle: White Mates in Two Deslock 12-15-2005, 12:32 PM Dunno how many chess players there are here, but attached is a pretty tough puzzle. It's white's turn, and he can mate in two moves. Feras 12-15-2005, 12:38 PM rook in a8 to b8 king in c5 to b5 maybe? spr grn8 12-15-2005, 12:38 PM white: pawn c-6 to b-6 Black: pawn a-7 to b-6 takes pawn, check white: King to b-6 Mate! lurch519 12-15-2005, 12:41 PM kinda hard to solve as we dont know which end of the board is whites and which is blacks Feras 12-15-2005, 12:45 PM how bout this move the classic knight jumps queen, bishop jumps queen, pawns jump queen, gangbang! dtorre 12-15-2005, 12:47 PM White: King C3 Black: King B6 White: Rook B8 easy Photic 12-15-2005, 12:50 PM My bad, that is a king isn't it. Feras 12-15-2005, 12:50 PM i think white is moving up black is moving down. dtorre how is the white king moving from c5 to c3? Luftwaffle 12-15-2005, 12:56 PM We're playing flying kings? Deslock 12-15-2005, 12:58 PM In puzzles like this, white's pawns are advancing upwards. Don't worry about "official" chess notation, as long as you write something descriptive. For instance, this works: white moves pawn c6 to c7 black moves pawn b5 to b4 (but it's not the correct solution) Asmoran 12-15-2005, 01:04 PM White: Rook to B8 Black: Pawn to B4 White: Rook to B6 Celronx 12-15-2005, 01:06 PM I can only get it in 3 moves. What's the answer? Feras 12-15-2005, 01:06 PM White: Rook to B8 Black: Pawn to B4 White: Rook to B6 if i was black the better move is king to a5 king takes pawn. Feras 12-15-2005, 01:11 PM hows about this white: king to b4 black: (black has no move at this point) pawns can't move and if king moves into either open square he gets taken by a pawn. (does this count?) is this one move or two? i never play eletronic chess with numbers and letters Asmoran 12-15-2005, 01:12 PM ah, yeah. Missed that about the pawn. Your solution results in a stalemate, so considering deslock's twisted logic, you've got the answer ;). stalemate he never specified the type of mate. Steakboy42 12-15-2005, 01:19 PM Answer: white pawn in C6 to C7 black pawn in B5 to B4 White Pawn in C7 to C8, changes to queen or bishop checkmate -Steakboy Feras 12-15-2005, 01:20 PM wooo go me! but im still looking for a checkmate answer. Asmoran 12-15-2005, 01:20 PM Answer: white pawn in C6 to C7 black pawn in B5 to B4 White Pawn in C7 to C8, changes to queen or bishop checkmate -Steakboy not checkmate - black king takes white pawn @ a5 Deslock 12-15-2005, 01:24 PM Your solution results in a stalemate, so considering deslock's twisted logic, you've got the answer ;). stalemate he never specified the type of mate.LOL. White can produce a stalemate in one move, I believe: King to B4 The question is how does white get a checkmate in 2 moves! (3 moves is easy) This is a very tricky puzzle... it's not nearly as straight forward as the previous ones I posted. No one has come up with the correct answer yet, so here's a hint: Advancing the pawn from c6 to c7 does not lead to a solution because Black can move b5 to b4. If White's next move is to a8 x a7, the Black king can then capture the White rook (a6 x a7). If White moves to c8, the Black king captures the White pawn (a6 x a5). I already have my next puzzle ready to go for after this one is solved :mdrmed: Celronx 12-15-2005, 01:27 PM Ok, I've got 2 (2) move mates. One would require you to be playing against a moron, the other depends on the rules you play. 1st White : Pawn to c7, or Pawn to d6 Black : King to a5 White : Rook to a7 This one requires the moron because anyone who could thing about the next move wouldn't take the pawn at a5 on that move. 2nd White : Rook to b8 Black : King to a5 White : King to b5 This one you move yourself into check, but it's covered by the rook....not really correct by the rules I always play by. Asmoran 12-15-2005, 01:27 PM No fair changing the question! :pfanndina :pfanndina :pfanndina And I know white could stalemate in 1, but the question specified 2 :P Asmoran 12-15-2005, 01:29 PM 2nd White : Rook to b8 Black : King to a5 White : King to b5 This one you move yourself into check, but it's covered by the rook....not really correct by the rules I always play by. Yeah, that one isn't legal Celronx 12-15-2005, 01:31 PM ^ I agree, but you never know.......... Feras 12-15-2005, 01:39 PM white: a8 to b8 black: if a6-a5 then white b8-b5 if b5-b4 then white b8-b6 i figured its the same move for white #2 just different length of movement based on black. Asmoran 12-15-2005, 01:41 PM if a6-a5 then white b8-b5 That doesn't initiate checkmate. Black king can go to either a6 or a4 to get out of check. Feras 12-15-2005, 01:44 PM That doesn't initiate checkmate. Black king can go to either a6 or a4 to get out of check. damn you're right sigh blue flash 12-15-2005, 01:50 PM check mate in 2 moves can't be done sorry try arain. Asmoran 12-15-2005, 01:56 PM I have to agree. I think feras and I hit on the correct answer in posts 14 and 15 Deslock 12-15-2005, 01:57 PM check mate in 2 moves can't be done sorry try arain.Yes it can. But it's very tricky... only an observant player with a thorough understanding of the game has a chance at figuring this one out. blue flash 12-15-2005, 02:04 PM i play chess alll the time and you can't get checkmate in 2 moves .if u are thinking of using the rook you can't because the white king would be in check . Asmoran 12-15-2005, 02:05 PM White: C6 to C7 Let's say the black player is aggressive, and he goes A6 to B7 to threaten the rook. White: C7 to C8, swap with Queen - checkmate But again, that would be a pretty stupid move on black's part. Asmoran 12-15-2005, 02:09 PM Actually, I think that's it: White: C6 to C7 Black has 3 moves: 1) A6 to B7 2) A6 to B5 3) B5 to B4 Case 1) C7 to C8, swap with queen, checkmate Case 2) A8 to A7, checkmate Case 3) Ignore the pawn, C7 to C8, swap with queen, checkmate Asmoran 12-15-2005, 02:10 PM Doh, nvm - case 3 is flawed Asmoran 12-15-2005, 02:11 PM Okay, I really give up this time. (I've told myself that like 7 times now, lol) Let's hear it. Deslock 12-15-2005, 02:17 PM Sorry Asmoran, that's not it (nice try though). blue flash, there is a solution, but again it's very tricky and only an observant player with a thorough understanding of the game has a chance at figuring it out. Once the solution is posted, I anticipate I'll be getting those death threats I mentioned (http://www.rx8club.com/showthread.php?t=78675). :Kill1: blue flash 12-15-2005, 02:18 PM 3 moves it the closest you can do it.no stalemate, checkmate in 3.i know how to play and play very well .i beat 50%of my opponents in 4 moves . :fingersx: xr2 12-15-2005, 02:25 PM White: C6 to C7 if Black:b5- b4 white: c7-c8 Queen black:a6-b7 white: c7-c8 Queen black a6-a5 white: a8-a7 staticlag 12-15-2005, 02:28 PM Got it. En passant. a5-b6 white pawn takes black pawn. a6-a5 black king forced move a8-a7 white rook takes black pawn, Mate! Steakboy42 12-15-2005, 02:32 PM Got it. En passant. a5-b6 white pawn takes black pawn. a6-a5 black king forced move a8-a7 white rook takes black pawn, Mate! black pawn is in b5, not b6, sorry -steakboy blue flash 12-15-2005, 02:32 PM this is your answer but it is wrong!!rook to b8 then king to b5 checkmate .but the king cannot move into to check so the game continues. trickshot 12-15-2005, 02:34 PM Got it. En passant. a5-b6 white pawn takes black pawn. a6-a5 black king forced move a8-a7 white rook takes black pawn, Mate! Well done!! :bowdown: Asmoran 12-15-2005, 02:35 PM Ah dang. I thought that pawn was too far down for that..... Deslock 12-15-2005, 02:37 PM ding ding ding! staticlag got it. Here's the explanation: There is no solution unless you think about the most recent move by Black that led to the current positions. The only move Black could have made to result in the current board is Black's pawn from B7 to B5. Thus White's first move is pawn from A5 to B6 (legal because of en passant). Black must move A6 to A5. White moves A8 to A7, capturing the pawn and mate. Steakboy42 12-15-2005, 02:40 PM I did not know that rule... -Steakboy xr2 12-15-2005, 02:40 PM Sorry I'm not very good a chess, but can someone please tell me where my solution falls apart? White: C6 to C7 if Black:b5- b4 white: c7-c8 Queen black:a6-b7 white: c7-c8 Queen black a6-a5 white: a8-a7 Asmoran 12-15-2005, 02:41 PM ^ The black king can take the white pawn and move out of checkmate xr2 12-15-2005, 02:43 PM ^ The black king can take the white pawn and move out of checkmate Of course I account for it in once case, but not another. This is why I'm not very good at chess. Thanks. blue flash 12-15-2005, 02:47 PM you have the pawn moving in the wrong direction look @howthe board is set up white is in the right corner and white starts at the bottom of the board. Steakboy42 12-15-2005, 02:49 PM I dont someone can explain the rules of en passant for me? -Steakboy staticlag 12-15-2005, 02:57 PM I dont someone can explain the rules of en passant for me? -Steakboy Look under the piece pawn, they have a good visual explanation. http://www.chessvariants.com/d.chess/chess.html Steakboy42 12-15-2005, 02:59 PM Makes total sense. Thank you, you just furthered my knowledge of the game of chess. -Steakboy xr2 12-15-2005, 03:00 PM I dont someone can explain the rules of en passant for me? -Steakboy Sorry if this doesn't make sense, I'll try. First, En Passant means "In Passing". You know how a pawn on it's first move can move 2 squares forward instead of one. What a pawn does move two squares, if on the very next move, and only on the next move, if the opponent has a pawn that could have taken the pawn that just double moved if it only moved one square, it may do so. This may do better: http://en.wikipedia.org/wiki/En_passant lshu 12-15-2005, 03:11 PM Damn! I already was thinking about en passant in my solution but I got it all wrong. I thought the black piece b5 takes white a5. Got it backwards!! :crazy: Deslock 12-15-2005, 03:11 PM Here's another explanation of en passant (similar to the wikipedia one): http://www.chessclub.com/resources/rules/Prise-En-Passant.html Also, the next rx8club lounge puzzle is up: http://www.rx8club.com/showthread.php?p=1161429 Altair4 12-15-2005, 05:07 PM White Pawn c6 to c7 if Black King takes pawn a5 Rook takes pawn a7 checkmate if Black Pawn to b4 Pawn to c8 (Queen or Bishop) checkmate blue flash 12-15-2005, 05:08 PM sorry but you still don't have check mate .please try again.nice ruling on the en-passant never knew that 1. |
