Can't find a mate in 5. But think I have found a mate in 8 1 Nxf8 d4+
2 Nd6 Bxd6+
3 Ka1 c4
4 Qc7 Bd6
5 Qxd6 Bc8
6 Qc7 Bh3
7. Qd8+ Bc8
8. Qxc8++ |
|
| Nov-29-11 | | sevenseaman: <BOSTER> You have a fine point there. <42...Bh4> is rather inane When <42...Rg8> looked easy and obvious. Obviously Black had no foreboding of the impending N sac. <PawnOfTheDead> No, it does not start with that. |
|
| Nov-29-11 | | hedgeh0g: <sevenseaman>
Nc7+ Kb8 Nxd5+ Ka8 Nxb6#
A nice mate, but not exactly problem-like. :) |
|
| Nov-29-11 | | hedgeh0g: As for today's puzzle, 43.Nxf5+ looks obvious, but one has to foresee that after 43...exf5 44.Re6+ Bf6 45.Qg5+ wins. A good standard of puzzles so far this week. Looking forward to the rest! :) |
|
| Nov-29-11 | | PawnOfTheDead: @hedgeh0g Not so quick. Nxb6 is an illegal move. I am thinking Ka1 is the move |
|
| Nov-29-11 | | sevenseaman: <Hedgeh0g> A charming effort but Nxb6# is illegal. The B at f7 does not allow the N to leave d5. |
|
| Nov-29-11 | | PawnOfTheDead: <sevenseaman>
1. Nc7+ Kb8
2. Nxd5+ Ka8
3. Ka1 Ba5
4. Nc7+ Kb8
5. Nxa6+ Ka8
6. Qb8+ Rxb8
7. Nc7++
Still too many moves |
|
| Nov-29-11 | | hedgeh0g: Haha, of course you're right. I'll give it another shot and then go to bed :) |
|
| Nov-29-11 | | hedgeh0g: I can only find mate in 9 beginning with Ka1.
e.g. Ka1 Rc8 Nc7+ Rxc7 Qxc7 Be6 Qd8+ Bc8 Qxc8#
Or Ka1 Re8 (to delay mate by a move by interposing the rook) Nc7+ Kb8 Nxd5+ Re5 Qxe5+ Ka8 Nxb6# |
|
| Nov-29-11 | | hedgeh0g: How can you possibly mate in 5? :/ |
|
| Nov-29-11 | | Nullifidian: Saw this one at once:
43. ♘xf5+ ♙exf5 44. ♖e6+ ♗f6 45. ♕g5+ ♔h7 46. ♖xf6 and now Black must either give up the queen or be checkmated. |
|
| Nov-29-11 | | karik: 1. Nc7+ Kb8 2. Nd9+ Ka8 3. Qb8+ Rxb8 4. Nc7# |
|
| Nov-29-11 | | Shams: <karik> 2.Nd9+ Kc9! |
|
| Nov-29-11 | | karik: Damn, I knew there was something wrong in my solution! |

|
| Nov-29-11 | | Alphonse1973: <sevenseaman> Solution: (1) Ka1!! Rc8 (2)Nc7 Rxc7 (3)Qxc7 Be6 (4) Qd8+ Bc8 (5) Qc8# (1) Ka1!! c4 (2)Nc7+ Kb8 (3) Nxd5+ Bd6 (4)Qxd6+ if (4)... Ka8 (5) Nxb6
if (4)... Kc8 (5) Qc7
(1) Ka1!! c2 (2)Nc7+ and mate in two moves. |
|
| Nov-29-11 | | PawnOfTheDead: <Alphonse1973> What happen in your first variation if black moves Kb8 rather than Rxc7. Remember that after Nxa6, the knight is pinned against the king. |
|
| Nov-29-11 | | PawnOfTheDead: <Alphonse1973> I see now. You are right. He goes for the b6 mate. |
|
| Nov-29-11 | | BOSTER: <Robespierre>
<I have absolutely no idea why this puzzle took me (an advanced novice chess player) 15-20 sec. to solve>.
According to your profile <my chess career was playing S.Reshevsky in 1965>. My question is : How long are you going to be <an advanced novice > chess player? |
|
| Nov-29-11 | | morfishine: <sevenseaman> The solution starts with 1.Nxf8 |
|
| Nov-29-11 | | bischopper: <ULhumbrus> I think its,the lucena position in rook and pawn endings you know how is it? and where can I have examples ? thank You |

IF A: ....Kh7, 44.Qg7#
IF B: ....Kh5, 44.Qg5#
IF C:.....PxN, 44.Re6+ Kh7, 45.Qg6# |
|
| Nov-29-11 | | sevenseaman: <hedgeh0g> was the first to get it right. a) < Ka1 Rc8 Nc7+ Rxc7 Qxc7 Be6 Qd8+ Bc8 Qxc8#> b) <Or Ka1 Re8 (to delay mate by a move by interposing the rook) Nc7+ Kb8 Nxd5+ Re5 Qxe5+ Ka8 Nxb6#> are both 5-move solutions. Confusion is only about no. of moves. In each case White mates on his 5th move. Then <Alphonse1973>
<(1) Ka1!! Rc8 (2)Nc7 Rxc7 (3)Qxc7 Be6 (4) Qd8+ Bc8 (5) Qc8# (1) Ka1!! c4 (2)Nc7+ Kb8 (3) Nxd5+ Bd6 (4)Qxd6+ if (4)... Ka8 (5) Nxb6 if (4)... Kc8 (5) Qc7> or 5. Nxb6# <(1) Ka1!! c2 (2)Nc7+ and mate in two moves.> too got it right.
There can be many combos when White mates in less than 5 moves. <PawnOfTheDead> hovered very close but was caught in the cobwebs. <morfshine> and <PawnOfTheDead> wanted to know if the solution started with <1. Nxf8>. I am afraid no solution can bypass the key opening move <1. Ka8>; a strange looking first move that remains unavoidable in any shorter solutions too. I feel very good about the sporting efforts of <Philipot> and <karik> who attempted it. <Shams> joined <karik> for a contribution of sorts; aah, the 9th rank!! There are some smothered mate scenarios too; < 1. Ka1 Rb8 2. Nc7#> being the briefest, there being more. So now I can safely transmit the solution to that kid in <San Jose, Ca.> from whom the query first came! He unwittingly started an earthquake! |
|
| Nov-29-11 | | TheBish: Hoang Thi Bao Tram vs Xu Tong, 2011 White to play (43.?) "Easy"
Black has skewered White's queen and rook, but White has a way out. 43. Nxf5+! exf5 44. Re6+ Bf6 (otherwise 45. Qg6# is coming) 45. Qg5+ Kh7 46. Rxf6, and there is no good way to stop 47. Rh6#. |
