 | | kevin86: I was looking for a bishop or knight sac. Instead the winning hand was a rook sacrifice. the following family check will win it. |
|
| Mar-22-16 | | YetAnotherAmateur: Rxf7+ obviously does the job, but it's important to notice that whether or not black takes the rook the correct response is Nxe6 to win the queen. |
|
| Mar-22-16 | | zanzibar: Came back to play over the game to see how Black got in hot water... Have to wonder why he played 15...c7-c5, it just looks bad, as even 16.dxc5 shows:

 | | patzer2: <JohnBoy> Thought you might enjoy the recent http://www.foxnews.com/entertainmen... report of 67-year-old Steven Tyler, who co-wrote the Aerosmith version of "Back in the Saddle Again," moving in with his 28-year-old girlfriend. I've enjoyed Steven Tyler as an entertainer and especially as an American Idol Judge. He seems to be a fun-loving and genuinely nice person. As a fellow 67-year-old grand parent (see the recent article at http://www.usatoday.com/story/life/...) I wish Steven all the best in his future endeavors. |

| Mar-22-16 | | Cheapo by the Dozen: I just calculated that White wins at least 2 pawns while smashing Black's position (because the rook is poisoned), and stopped there. |

| Mar-22-16 | | loveswesterns: I agree with MostlyWatch. As a novice, it would be instructive to me if there was an indication of a player resigning, and then the puzzle continued to its most logical mate conclusion so I can see what the GM saw when he resigned. As it is, I learned nothing from this "easy" puzzle. As a novice, I don't have the ability to visualize steps in my head, so continuing the puzzle would provide a visual aid for me to follow the game to its conclusion (had the player not resigned). This would be especially helpful for the Monday and Tuesday puzzles. |
|
| Mar-22-16 | | FlashinthePan: There is no way this is an easy puzzle if one is supposed to have seen all the variations leading to mate to have solved it. |
|
| Mar-22-16 | | Grnhorn: Being a novice also.. I found it hard to go over all the possible scenarios to this game! but I did found the exercise helpful.. we can't be spoon fed everything and learn at the same time. So yeah!, the puzzle was harder than a normal Tuesday! |

| Mar-23-16 | | zanzibar: <loveswesterns> yes, that's one problem with the <CG> puzzles; they're nice positions but you don't get to play them out. Admittedly, nobody really does this well, in the sense of playing out all the variations. But I think the best place for improving tactical play is over at <ChessTempo>, at least at my level. http://chesstempo.com/chess-tactics...
If you register you can get a rating, and you'll be fed problems according to your level. <CT> forces you to play out the line, to truly test understanding. And all the positions come from real games.
Some people lack the patience for it (when you fail a problem, you really fail), but it's well worthwhile. Be sure to read the problem comments left by other users to make sure you saw all the lines involved, including those unplayed. Try it, and see what you think.

 | | HeMateMe: <Pawn Power> sits within my meager chess library. |
|
| Jun-18-21 | | catlover: The author of "Pawn Power in Chess" gives up his queen for three pieces, and then uses his pieces to defeat his opponent. Nice game title. |
|
| Jun-18-21 | | Andrew Chapman: Black spent 2 tempi opening White's f file for him, to gain only a bishop for a knight. |
|
| Jun-18-21 | | Nov8: Why chess engine is still not working? |
|
| Jun-18-21 | | Brenin: Despite this collapse, Prins was quite a good player, with an interesting win against Euwe <Prins vs Euwe, 1946>. |

 | | scutigera: People keep calling this game a queen sac, but it isn't, of course; White gets three pieces and the Two Bishops in exchange for the queen and the isolation of his QP. And look at the position after 11 Bxc4: White has three well-developed pieces while Black has nothing off the back rank except his King. Then Black moves his knight four times only to trade it off; white loses the bishop pair in exchange for castling, centralizing his QR, de-isolating his QP, and opening a file for his KR, ending up a pawn down in exchange for at least five tempi and the initiative. File this one under "positional," I say. |
|
| Jun-19-21 | | WorstPlayerEver: <scutigera>
You fail to mention that White get 3 pieces MINUS A PAWN for the Queen.
Black gets Q+P vs BBN
In simple words: a sacrifice. |

 | | Phony Benoni: Psychologically, any time you dump your queen for something that's not a queen, it counts as a "queen sacrifice". It doesn't matter how much material, or how many positional advantages you gain in return. It's still a "queen sacrifice", and you will always refer to it as such with pride. |
|
| Jun-19-21 | | Z legend 000000001: Queen for two rooks, a sacrifice? Hmmm... |
|
Jun-20-21
| | Phony Benoni: Well, why not sacrifice the queen for two rooks? An even material swap doesn't mean that everything is even. A sacrifice is nothing but a trade that appears bad on the surface for one side -- until you read the fine print. Consider this position, from J F Smyth vs H Helms, 1915 
click for larger viewThe game proceeded 22...Qg2+ 23.Kxg2 Rxg3#. Beautiful. But is it an example of a queen sacrifice? By <scutigera >'s definition, I think not. Yes, Black gives away his queen, but he immediately receives compensation in the form of a checkmate -- not to mention an extra pawn. No muss, no fuss, no risk. Well, outside of a possible heart attack. Helms was an old man of 45 at the time. By constrast, Kmoch's idea has more potential to be a sacrifice because there is more risk involved. Yes, White may receive sufficient compensation, perhaps even a winning game --- but the position still has to be played and the game won. The foregoing is, of course, mostly a joke. (Had too much time on my hands yesterday when <CG> went down.) We all know Helms' 22...Qg2+ was a queen sacrifice. It's imprinted in our DNA. We know one when we see it. |

 | | fredthebear: <An even material swap doesn't mean that everything is even.> So true <Phony Benoni>. One color or the other misses/needed the removed material more so than the opponent. |
