move queen to the right put king in check.
black king has to move right.
then move rook down to put king in checkmate.

No, it's

(click to show/hide)

bishop to f8. If then Black's bishop takes b2, move white bishop from f8 to h6. Checkmate. If he moves his black king from c1 to b2 instead to kill the then exposed white tower, move white queen from a3 to a2. Checkmate. Instead Black could try moving his knight from e1 to c2 to threaten a1 and keep it queen-free, but then white queen could wipe the knight from c2 and checkmate too. Any other Black move and White can go for standard queen&tower KO.

Move the rook on the left down and the bishop on the left diagonally up and right.

black king has to move right.
then move rook down to put king in checkmate.

problem is it's mate in more move than 2, black put piece to death destroying your dream of mate in two

Quote from: SixThumbs on December 25, 2011, 07:57:24 pm

Move the rook on the left down and the bishop on the left diagonally up and right.

black put his bishop in between your and his king (Bg7-c3) and you mate in three with Qd1#

also, please put your response into spoiler so we can keep drama about it.

ps: if you could use algebraic notation so I can understand a bit.

pps what is algebraic notation:

K-king
Q-queen
R-rook
B-bishop
N-knight
 - pawn
you put the sign of piece + case of start and final case. if capture put an x if check put an + if checkmate put an # other sign such as ! or ? can be use to express the quality of move.

ex:  a game
the famous Legal's mate
starting:

1. e2-e4(pawn from e2 to e4)  1... e7-e5
2. Bc4 (Bishop to c4, not obligated to put Bf1-Bc4)   2... d4
3. Ng1-f3      3... Bc8-g4 ?!(express somewhat imprecise move)
4.Nb1-c3       4... g6 ? (really black should start developing)
5. Nxe5!!(beautiful! queen sacrifice or a pawn up + good position if black take knigth)   5... BxQe1 ?? (oups queen seem too good now, but after...)
6.Bxf7+  6... Ke7
7. Nd5# (checkmate and one of the most know finish of chess)

how many moves does it take

Title: Re: The chess topic! (with problem to resolve! and game to play!)
Post by: isatis on December 26, 2011, 08:21:53 pm

you will queen, against the best play, in 9 move (10 white and 9 black)
objectively you could queen in 10, but that's not best play in human point of view.

move count doesn't really manner as there is only one possible way to win if black play well.
i'll show the winning sequence tomorrow. 

Title: Re: The chess topic! (with problem to resolve! and game to play!)
Post by: Paul on December 26, 2011, 09:02:47 pm

Without going further into detail I'd say I would put the white bishop on A7, offering the piece to the black bishop. It seems to be a sacrifice without gain at first but it also kinda forces the black pawn to stay put, blocking black bishops field of action and so Black can't threaten white pawn's conversion field H8 easily.

what if black play correctly and just don,t take your bishop playing Ba1 instead?

(go Paul go! you got first move!)

Title: Re: The chess topic! (with problem to resolve! and game to play!)
Post by: Paul on December 27, 2011, 12:02:40 am

Well, white bishop is still suicidal, so Bd4. Then Black would either take the white bishop with his pawn or his own bishop, with the first option being more clever. Anyway I don't think he can prevent the white pawn from converting after that because the white king can block the way of Black's pawn conversion while black king can't catch up with the white pawn.

no one got that pretty problem... isatis will reduce difficulty so!

here's an ending problem from one of my game against a WIM, this game was played long time ago so I messed up the thing and got it wrong ( a bit of time pressure also and some dump psychology thing): after that, rook ending become one of my force.

so black to play and win

the thing is already well started, black a pawns up and got two past pawn, but beware it's a tad more difficult than it look

also, to understand why I messed it up, here the game, it's rollercoster all the way!

Post by: SixThumbs on December 28, 2011, 09:11:07 pm

To be honest, unless the problem is done in less then two moves I don't understand how this is supposed to work since we're not playing a real chess game and I don't understand the motives and intentions of a player just by looking at the pieces on the board.

Title: Re: The chess topic! (with problem to resolve! and game to play!)
Post by: isatis on December 28, 2011, 09:27:10 pm

the last problem is a peculiar one because it's one of my game ending problem: it's only to get a better understanding on rook ending, the yesterday one is a forced win for black, the other one is also a forced win for white, but with some blocade understanding attach on it.

it is true that a chess problem is never like a chess game, put it will increase your theorical advantage against someone because you'll finally see those tactic you missed.
the motive in the game against WIM was to draw for me and her needed to win badly, i got a bad early position and should have lost, but she made a mistake and I gain upper hand, unfortunately I didn't saw good at the end and it finished in a draw.

 
here's another of my game, against one of the finnest blind chessplayer of canada ( he was plaing without his special board)
i'm white, he's black.
for the record I played this game rather well and then busted one of my past pawn for invisible counter-play in queen side, luckily for me, my opponoment, play imprecise move making my awful a pawn better, now he is in the struggle, he need to win in order to prove himself he can still teach me something (both of those player where my chess ''coache'')
 
black to move
now I ask you a question:
do Qc7-b6 is a good move?

if yes, put on why, if no put on why and better move.

Post by: Paul on December 28, 2011, 10:25:55 pm

Don't think it is clever because then the white pawn on a6 can just keep advancing and threaten the tower while ignoring Black's queen exchange offering. White loses then of course his old queen, but gets a new one shortly after and kills Black's tower. The tower advantage is pretty deadly then in the endgame. The advanced pawn on e5 is good for White too.

boom got it, that was one of the funniest finish I made : a pawn going all the way from a2 to a7 without interruption and winning!

starting position:

visitors can't see pics , please register or login




bah... yes in a theorical way, but as this is a game with time and because we are human he could have resisted and even possibely draw with move like Ra8 followed by Ra7 and here here's white going to go with loooooong boring way of the kingside majority with f4 and such while watching for those two connected past pawn.

 As we know that rook endgame are drawish when all pawn on one side, as black i would try to exchange my two connected past pawn for white one (the a one) and exchange queen leading to this peculiar extremely drawish rook endgame.

the winning is more diffficult than it seem, I must create another past pawn in order to win, this can be done by f4-f5-e6 BUT black can play play h5 and i'm in trouble because the way is longer now, and I can't play g4 rigth away (after black plays 32... Ra7) because of a beautiful pattern of perpetual check... hum, let see if you'll found that one Paul:

position after 31... Ra8 32.Ra1 Ra7 33. g4=
black to play and draw
visitors can't see pics , please register or login



Like said before,my pawn majority was on kingside and it was a 4vs3 one... so two plan: a) block king side and try to exchange all piece and win a pawn, not realizable
B)  try to bring king to queen side so if he manage exchanging queen my king will be ready to jump into queenside to blockade those pawn and force the win, unfortunately black can prevent this with check so I must be very careful on how I do this.
C) try to move all those pawn on my king side with move such as h3-g4-f4-f5-e6
take a long time but black has nothing to do so go on! it will take looong (aka more chance for black to organize defense and get a draw but i had nothing better to do, and the least I can get is a draw so.)



this could have been a very good endgame, but it finished in a more dramatic way.

Black to move and WIN!!

3                 3
4                 4 (here play and stop)

don't forgot those nasty past pawn you both got!

(click to show/hide)

first one: as Paul said Bf8 and mate follow no matter what black do
second one: as paul said but with two little move he forgot: Ba7 trying to attract the evil bishop, than after Ba1, Kb1(move paul forgot to mention) Bc3, Kc2 Ba1, Bd4! BxB Kd3 win because black pawn gonna be blocade and white h pawn gonna queen
third one: RxR RxR than you simply play Rd8 and if evil white bishop move than play Nf3+ and boom you got a free rook for you pesty knight!
Fourth one: many possible answer, best is : Rd8+! Ke2 Re5+ Kf2 Rd2+ Kg3 Ree2! (look at those nasty rooks on seventh rank!) Rxb4(pff rook badger don't care) e5!! (take that) Rb7+(rook badger don't give a shit) Kd8! h5 (oh deer try better plz...) Rg2+ Kh4 f6! black win (rook badgers won!)
in game I played with  stress and i miscalculated a draw after Rd5+ Ke2 Rc4! (it was a difficult win for black in fact) and as I overestimated my opposant I forced draw with Rd5 Ke2 Re5+ Kd2 Rd5+ etc...
 fifth one: simply play a7 as Paul pointed out and you win
sixth one: If black play Qc8! he force a draw after Qxa7 (we don,t want our pretty pawn in a6 to disappear) Qxg4+ Kf1 Qc4+ and if Ke1 Qc3 win rook (still draw) and if Kg1 g2 we repeat position with Qg4+

hope my little problem bring you fun (or headache or if you're like me : both!)

apart from this miracle of dexterity ( may seem special, but I can't play 1min chess blitz IRL because I always splat the piece all apart... by luck i got internet!)
it take a lot of patience to enjoy chess (aka get a good lvl) I always laugh and feel a tad bad when I beat an ''average all-round player who played a lot when he was in high school'' giving them a queen advantage... having an expert as teacher may help, international master is even better though!

usually it's me that get the rage ( me:checkmate in 4. other: FUUUUUUUUUUUUU *destroying the position* me: replacing the position and re said checkmate in 4. other: GTXting or trying a revenge that usually go to situation 2)
2: the worst thing I made was to beat up someone with equal piece, than a knight down, then a rook down then a queen down, he laughed when I took of the queen, he didn't say a word when he got checkmated after a sacrifice.

yes, i'm a check jerk
