 | | FSR: <david p> As I'm sure you know, CG.com grades its puzzles, with Monday being the easiest. That makes a lot of sense to me, since its readers include players running the gamut from beginner to grandmaster, and any problem is going to be too hard or too easy for some players (probably both). If the Monday puzzle is too easy for you, try something else like chesstempo.com or Shredder's 48 problems a week. http://www.shredderchess.com/online... It's not as though CG.com is the only chess site in the world. |

| Aug-06-12 | | bachbeet: Got it very quickly. Only thing was that i couldn't believe it was that easy so I kept looking for something I might have missed. Didn't see it so stuck with the Q sac. |
|
| Aug-06-12 | | whiteshark: 18.Qxf8+, and that's it! |
|
| Aug-06-12 | | mike1: yes, got the puzzle but the main question is how to do better with black. 16... Bxc4 is a big mistake.
Is black really lost after 16... c5?
I dont think so and it is white who has to think about 17... Bxc4" |
|
| Aug-06-12 | | Once: <mike1> Fritzie says that 16...c5 would have been worth around -3. In other words, black is winning to the value of roughly three pawns. By contrast, after 16...Bxc4 white is winning by +4.5. To avoid the rook sac along the e file black has to give up queen for rook. There is almost a queen's difference between 16...c5 and 16...Bxc4. Black's 16...Bxc4 was a clear mistake. In essence, white's plan in this game was to play for one trick - the back rank mate. Against best play it should not have worked. But OTB it was scary enough to frighten black into going wrong. |

 | | HeMateMe: I believe the tactics books refer to this as "distraction", as black's king has been distracted to f8, then mated. |

<18.?>
Material: in some positions, material just does not make a difference. It is in Black's advantage here objectively, ♘+3♙ vs ♖, but it tells not even 10% of the position. Candidates: <[Qxf8†]> The combination itself is straightforward, a little boring even for Monday standards: <18.Qxf8† Kxf8 19.Rd8‡ 1-0>. Definitely more interesting should be how in the world this position arose. White's queen is clearly still on h8 after a Qxh8, but he did lose three pawns and a Knight in process, and the queenside of White is not really that stable either. In fact, some of the earlier kibitz analysis shows that Black was winning after a strong exchange sac, Rh8 for Ng5, but couldn't finish up. Complex positions, come with great resp.... wrong quote... in complex positions, the better player wins. |

| Aug-06-12 | | Chesschatology: Poor old Aaron. He was coaching my school around the time this game was played. For some reason he never showed it to us... |
|
| Aug-06-12 | | lost in space: I love Mondays!
18. Qxf8+ Kxf8 (only move) 19. Rd8# |
|
| Aug-06-12 | | zb2cr: Lure Black into position to have a back-rank mate sprung on him with 18. Qxf8+, Kxf8; 19. Rd8#. |
|
| Aug-06-12 | | stacase: I looked at the rook sac first, then I looked at the Queen sac. So it took five seconds instead of two to figure it out. |
|
| Aug-06-12 | | dufferps: Very strange game - Black seemed prone to move his pawns to gain position, but then on the 10th move when pawn to g7 seemed the obvious move, he gave up position for a bad exchange. |
|
| Aug-06-12 | | Marmot PFL: Looks like a bar room blitz game, considering both players are over 2500. |
|
| Aug-06-12 | | dufferps: Shows how much I know. I see black's 10th move as a strange blunder, and the other kibitzers, backed by Fritz, rate it as a "strong exchange sac," and attribute black's demise to his subsequent play. |
|
| Aug-06-12 | | gars: God save the Mondays! |
|
| Aug-06-12 | | YetAnotherAmateur: <dufferps> I'd rate black's mistake as primarily shuffling that 1 knight around while never touching many of his other pieces. Something quieter like Nd7 seems like it would have given black more to work with. |
|
| Aug-06-12 | | TheTamale: I actually stared at this for a few minutes thinking, "If only White had a rook on the h file!" Then I realized it was the exact same thing only on the d file. So apparently now a single cup of coffee does not suffice for Mondays. |
|
| Aug-06-12 | | dragon player: This one is really easy:
18.Qxf8+ Kxf8
19.Rd8#
Time to check.

Right

| Aug-06-12 | | kevin86: Here is an unusual case where a king is chased into a bank rank mate. |
|
| Aug-06-12 | | BishopofBlunder: Where black went wrong was by playing 1...d5. I believe Deep Blue or Hydra would back me up on this. Certainly Tal or Morphy would. |

 | | chrisowen: Does it each in 18.qxf8+ in claws it ground in kxf8 in liberty it rough in 19.rd8+ it seem like for in open free the kraken, feel the wrath, overload whale you back! |

 | | perfidious: < BishopofBlunder: Where black went wrong was by playing 1...d5. I believe Deep Blue or Hydra would back me up on this. Certainly Tal or Morphy would.> There's one small problem with your hypothesis: here's one game (not the only one, either) where Tal answered 1.d4 with 1....d5 (Timman vs Tal, 1988). If you do a little digging, you'll discover that there were numerous others in which he used the move order 1.d4 Nf6 2.c4 e6 3.Nf3 d5 to play either the Semi-Slav or Semi-Tarrasch QGD lines. |

 | | gawain: I've never before seen a back-rank mate like this one! 18 Qxf8+ Kxf8 19 Re8# as Black's poor king is trapped behind his e,f and g, pawns with no help needed from the edge of the chessboard. |

| Aug-06-12 | | nirvanapirate: QxB and the King is toast! |
