 | | Honza Cervenka: <Is there any defence against Rf6> I think that there is no satisfactory defense for black. After that move white threatens with mate in two on f7/d7 and 24...Qe7 doesn't help for 25.Qxh8+ with mate. |
|
| Jul-11-06 | | dakgootje: Second many others before me: Lot moves to look at, so lot of candidate moves, so lot of things to consider and i didnt notice Rf8 until all others turned out to be wrong as they didnt work ^^ |
|
| Jul-11-06 | | Richerby: <cyclemath: <soltari:I came up with Rf6> Is there any defence...?> In a word, no. 24.♖f6 ♕g1+ 25.♖xg1 ♘c5 26.♕xh8+ ♔e7 27.♕g7+ ♔e8 28.♖f8# is the longest Black can drag the game out according to Fritz. |
|
| Jul-11-06 | | Dres1: Oops.. i thought it was Rf6... anyone else see this move? its not as forcing but might also work. |
|
| Jul-11-06 | | NeddieO: I did not find 24.Rf8+...I used 24.Qxh8+ Bxh8 25.Raf1. I don't see Black having any helpful defense after this. Maybe Q down to either e7 or f8. But none the less, Rf8+ is by far the nail in the coffin. |
|
| Jul-11-06 | | pogo5: 24.Rf8+ , a line-clearance sacrifice that also leads to a self-block by the Black Q or R on f8 so as to allow the mate 25.Qd7#
Very easy when you are used to solving mate in two problems!!
I recommend http://dhost.info/matein2/index.php
for mate in two practising :-) Hard positions, watch out! :-)) |
|
| Jul-11-06 | | Soltari: <Richerby:> Thanks for the analysis, I guess 24.Rf6 wasn't that bad after all. But 24.Rf8+ is sooo much nicer, I still can't believe I missed it :). |
|
| Jul-11-06 | | Fezzik: Boy, I thought this was the hardest Tuesday puzzle I'd ever seen. I missed the easy mate in two and focused on a long forcing line: 24.Re7?!! (the question mark for missing the easy win, the two exclamation marks for working out the hard win. I may have missed something, but I do think this works.) 24...Qxe7 25.Qxe5 Rg8 (or 25...Rf8) 26.Nd6+ Kd8 27.Bxa6 (this may not be the best move here. I couldn't work out what happens after 27.Rd1) Bxa6 28.Qa5+ Qc7 29.e7! Kd7 (forced) 30.Qf5! and White wins. The two main lines are: 30.Qf5+ Kxd6 31.Rd1+ Ke7 32.Qh7+ winning the Queen.
30.Qf5+ Kxe7 31.Re1+ Kxd6 32.Qe5+ Kd7 33.Qe6+ Kd8 Qxg8+ and White will mate. As I said, I thought this was the hardest Tuesday I'd ever seen. I worked it all out, but missed the easy mate in two! |
|
| Jul-11-06 | | zb2cr: Deceptively simple...White forces Black to block the key f8 square and then mates with 25. Qd7#. I'm with <Fezzik> on this one--I found it hard for a Tuesday puzzle. It took several minutes of concentrated thought to work it out. |
|
| Jul-11-06 | | think: This was a toughie...
I calculated Nd6+? Qxd6
25. Re7+? Kd8??
26. Rd7
of course I missed 25. ... Qxe7!

 | | thegoodanarchist: A cute little clearance sac that took me half a minute to find. I thought it was my hangover, but other people had a tough time too. The reason is our natural psychological block against leaving the queen en pris... |

 | | al wazir: <monad: What was the point of 1...d6?> Are you picking on the Pirc? It's one of my favorite openings. |
|
| Jul-11-06 | | YouRang: I agree with <zb2cr> "deceptively simple". I spent a lot of time trying to employ the white knight, bishop, the other rook...but nothing. Finally (I told myself), this is TUESDAY, it shouldn't be that hard! So I started looking at dumb checks, and it wasn't long before I found it. I guess I would have missed this in a real game. :-( |
|
| Jul-11-06 | | YouRang: I guess 24. Rf8+ would be a combination clearance-sac and decoy. Clearance sac = clear path for queen to get to d7
Decoy = force the black rook or queen to f8 where blocks the black king's only escape square. |
|
| Jul-11-06 | | Castle In The Sky: Got it, but it was a synapse burner for me. |
|
| Jul-11-06 | | greensfield: cuendillar: granted 24.Nc7+ is just an intermezzo. But with this move you can also find 25.Qxh8+ to mate in the following:- 24. Nc7+ Bxc7
25. Qxh8+ Qf8
26. Qxf8# |
|

 | | kevin86: <greensfield> after 24 ♘c7+ ♘xc7-the bishop doesn't have to leave his post. As stated above-the rook sac does two things:It forces black to block his king's only would-be escape square and it clears the runway for the queen to land on d7. |
|
| Jul-11-06 | | GoldenKnight: <greensfield> Why not 24... Nxc7? |
|
| Jul-11-06 | | dabearsrock1010: The biggest blunder by black, regardless of anything tactical, is not castling at some point. Probably 14...O-O? |
|
Jul-11-06
| | Honza Cervenka: <GoldenKnight: <greensfield> Why not 24...Nxc7?> 24.Nc7+ Nxc7 25.Rf8+ leads to mate. In fact, as <greensfield> has written, 24.Nc7+ is only an useless but also harmless intermezzo which allows different mate in case of eventual 24...Bxc7. |
|
| Jul-11-06 | | dabearsrock1010: or 14...O-O-O. Kingside might be weaker. |
|
| Jul-11-06 | | Whitehat1963: Yay! I got it. I didn't get yesterday's though. |
|
| Jul-11-06 | | pggarner: White has a pretty mate (or wins the black queen) if black had taken the kingpawn with 18...Kxe6, namely 19.Bc4+ Kd6 20.Ne4# |
|
| Jul-12-06 | | EmperorAtahualpa: Yup, got this one! Took me 10-15 seconds. |
|
| Apr-06-09 | | WhiteRook48: where did Black err? |
