|Oct-07-09|| ||chrisowen: As a weds puzzle debatable it is, definately seen this one before. Qe5 strikes it down so black's queen cant move without giving up the a4 pawn or mating on b8 next|
|Oct-07-09|| ||Samagonka: Very good puzzle. Couldn't get it though I looked long enough.|
|Oct-07-09|| ||YouRang: Once you realize that black's queen is the only thing preventing Rxa4#, the solution is obvious. |
30.Qe5 threatens the queen and Qxb8#, and it also prevents the black queen from giving check at e3. In short, black is burnt toast.
|Oct-07-09|| ||MiCrooks: Agree with Rang...just took a few seconds to find the right square to distract the Queen from...e5 is perfect in that it covers all of Black's checks AND hits the Rook on b8 a second time so the Queen can't just slide over.|
a4 looks like a major blunder. I wouldn't want to be Black but b6 looks like it might hold out for a while. For now White can't crack it open with b4 though there still might be some tactical trick available.
|Oct-07-09|| ||doubledrooks: I went with 40. Qe5, with the idea of distracting the black queen from protecting the a4 square (if 40...Qxe5), while also threatening the black rook. Black cannot meet both threats without losing serious material (40...Rxf8 41. Qxe4).|
|Oct-07-09|| ||Sneaky: Today's was easy considering yesterday's puzzle Zsofia Polgar vs A Rabczewsky, 1989 (30. ?) which pretty much set us up for this. A Queen forking two pieces happens a lot with bishops and knights, but to fork rooks and queens is much for rare. For that reason even good players can overlook the resource.|
|Oct-07-09|| ||wals: What Black could have done
Analysis by Rybka 3 1-cpu:
1. (1.06): 39...Qb4 40.Rxb8+ Kxb8 41.Qe5+ Kc8 42.Rf1 Kd7 43.Rf7+ Ne7 44.Rf6 Qd2 45.Kh2 Qb4 46.Qe6+ Kc7 47.Kh3 Kb6 48.Rf7 Nd5 49.Qc8
2. (1.34): 39...Qe3+ 40.Kh1 Rxf8 41.Rxa5+ Kb8 42.Qxf8+ Kc7 43.Qg7+ Kb6 44.Ra4 Qe6 45.Qd4+ c5 46.Qd2 Qe5 47.Rh4 Kc6 48.Rh6+ Kb5 49.Qd3+ c4 50.Qd1 Qe4 51.Rh5
|Oct-07-09|| ||antharis: I think I got it. 40. Qe5. Its a classical distraction. The a4-pawn is protected by the black Qe4 and Rxa4 would be instant mate. Possible continuations for black:
Qxe5 41. Rxa4#.
Qb4 for example 41. Qxb8#.
Qe3+ 41. Qxe3 Nxe3 42. Rxa4#
Qe3+ 41. Qxe3 Nb6 42. Qxb6
Rxf8 41. Qxe4
So black loses at least the Queen. LOL
Time to check.
|Oct-07-09|| ||antharis: Nice one by the way. Simple and instructive.|
|Oct-07-09|| ||David2009: Wednesday's problem A Giri vs F A Cuijpers, 2009 White to play 40? Medium/Easy|
40 Qe5 forks Q and R: the Q cannot be taken because of Rxa4# and Black has no useful check. Is it my imagination or are the problems getting easier? Time to
|Oct-07-09|| ||SamAtoms1980: 40 Qe5!!!
Jaw, meet tabletop.
|Oct-07-09|| ||muralman: QE5. My chess playing son saw it first. It is a sweet move. I will go back through the game,|
|Oct-07-09|| ||akapovsky: A bit soft for a wendsday if you ask me.Please excuse my bad english.|
|Oct-07-09|| ||whiteshark: <40.Qe5> for evident reasons: Threat is 41.Qxb8# or if 40...Qxe5 41.Rxa4#|
|Oct-07-09|| ||WhiteRook48: I tried the moderate 40 Qg6|
|Oct-07-09|| ||openingspecialist: I am surprised. This took me the time it takes to do Monday puzzles. The concept is nice.|
|Oct-07-09|| ||patzer2: The turning point for Giri in this game appears to be his true pawn sacrifice 22. d5!? |
It won not because it was a completely sound gambit, but rather because Giri was better prepared to handle the complications than his opponent.
In a difficult position, Black missed finding a few defensive resources that might have held the game. Specifically:
(1) 23...Rf5! seems to refute the pawn sacrifice as 24. Rxf5 Nxe3 25. Rb5+ Nxg4 26. Rxb3 e3! gives Black good winning chances.
(2) 29...Rhd6! would have held the position with a slight advantage after 30. g3 Nxc3 31. bxc3 Rg8 32. Qf5 Bxg3 33. Qf7 Qxf7 34. Rxf7 . Here, with an extra pawn Black can push for the win and is in no danger of losing.
|Oct-08-09|| ||patzer2: After playing back over the suggested improvements 23...Rf5! and 29...Rhd6!, I still think they're sound. However, I also think it would be difficult for Black to force a win in these positions and that White retains excellent drawing chances. |
For example 23...Rf5! leaves White an exchange up, though a lot of pawns down. Also the extra pawn in the 29...Rhd6! line is not a great advantage and is likely not worth much more than a draw.
So my conclusion is that the 22. d5!? gambit may be sound in the sense that it gives White winning chances with lots of opportunity for Black to go wrong. It may also be sound in the sense that even if Black finds the best moves, White with strong play can probably still hold the draw.
|Oct-08-09|| ||patzer2: Another interesting true sacrifice in this game is Giri's demolition 18. Rxf7!? If Black accepts it, I'm not sure White has much more than equality after 19. Bxg6+ Kxg6
20. Qg4+ Kf7 21. Qxd7 Rd8 22. Qf5+ Ke8 23. Qg6+ Kd7 24. Bf4 =.|
However, I'm beginning to think Giri's play with all these exciting sacrifices is more like Tal's than Fischer's. Certainly he's an opponent to be feared, since he is not afraid to take risks to try and force the win in difficult positions.
|Oct-08-09|| ||kevin86: 40 ♕e5!!. Black's queen is overworked. White threatens mate at b8 and the queen.|
She cannot take and must be lost.
|Apr-23-10|| ||Richard Taylor: Nice finish!|
|May-19-10|| ||thickhead: Black Q was overworked (overburdened)a la Nimzowitch|
|Aug-16-10|| ||Whitehat1963: Beautiful last move.|
|Jan-19-11|| ||sevenseaman: Incandescent! Almost every game he creates a tactical shot.|
|Dec-28-12|| ||piltdown man: What a beautiful final combination.|
