| Nov-01-06 | | YouRang: Nice. Happily, I've ended my losing streak with the last couple Wednesday puzzles. As <Marmot PFL> pointed out, the f2/f7 squares are very frequently the focal points of such puzzles, and with a bishop, knight and rook all hitting f2, it wasn't hard to see where to hit. |
|
| Nov-01-06 | | YouRang: <InspiredByMorphy><Just remember, there are no stupid questions only stupid answers.> Uh, are there any stupid questions? ;-) |
|
| Nov-01-06 | | kellmano: <YouRang> No, but this is a stupid answer. |
|
| Nov-01-06 | | Rubenus: A bishop on g4 or g5 and a knight on f3 or f6; the knight goes to e5 or e4 by sacrificing the queen. Quite a well-known trap. |
|
| Nov-01-06 | | brainzugzwang: <Deefstes> I was trying to make 12...Bxf2 work, too, and got it to 13.Kxf2 Nxe4+ 14.Ke3 Qxg5+ 15.Kxe4, and I couldn't find anything to force mate directly out of ...Qf4+, so I settled for ...Qxh4+, winning a clear piece and a pawn. Should be enough to win, but certainnly not as interesting as the game solution. |

 | | kevin86: I guessed this one in a shot-because I had already seen it. It is another fine version of Legal's mate. It almost qualifies as a Monday puzzle. |
|
| Nov-01-06 | | WarmasterKron: 12...Nxe4 jumped out at me as the move to make, but I cleverly managed to talk myself out of it. I went for 12...Bxf2+ but it now strikes me that 13.Nxf2! (13.Kxf2? Nxe4+ and Qxg5; 13.Kf1? Bxh4 14.Bxh4 Nxe4+ )leaves black with no advantage at all. |
|
| Nov-01-06 | | Olympos: Very easy and beautiful. |
|
| Nov-01-06 | | greensfield: <Fisheremon:> <Bxf2+ was possible on 11 th move (Black could win the game, same if on 13. Qa4 of White, but Horowitz decided to cooperate in making a naive mate).>
Yeh, incredibly from move 11. Horowitz seems to have cooperated by finding 3 inferior moves in a row! |
|
| Nov-01-06 | | DoctorChess: Lovely trap! I'm 3 for 3. That's right Doctor's back but just for 2 more weeks :-) |
|
| Nov-01-06 | | zb2cr: Darn--went for 12. ... Bxf2+. Obviously if 13. Kxf2, Nxe4 (double check); 14. Ke3, Nxg5 leaves Black a piece up. However, I jumped to a conclusion by neglecting the White Knight on e4 being able to capture 13. Nxf2. |

 | | playground player: Yay! Got it! But I wonder if I would've found the right move if it had been one of my games, not someone else's. There's something about actually playing a real, live opponent who wants to beat you... |
|
| Nov-01-06 | | aazqua: Nice mate, but this is way too easy for Wednesday. |
|
| Nov-01-06 | | VanPoolPlayer: I had it up to the last move, but I was trying to move the bishop to reveal a check by the rook. I could see a perpetual check by black with this tactic, and a queen-rook fork, but neither of these seemed worth giving up the queen. I missed the charging knight. Any advice on how to improve my visualization depth? I am only good to 2 or 3 moves, and my main opponent is only good to 1 or 2 moves, so I am not getting any better! |

 | | thegoodanarchist: these types of games always make me think "why didn't he castle???" |
|
Nov-01-06
| | thegoodanarchist: for example, 11. O-O and there is no debacle on f2 (at least, for the time being...) |
|
| Nov-01-06 | | LivBlockade: <VanPoolPlayer> The discovered checks (Black's Bishop moves giving check with the Rook) would normally make sense to look at, but here White will have a Bishop on e7 which can capture the Black Rook, putting a quick end to Black's attack. After seeing that, one might notice ...Ng3 mate. |
|
| Nov-02-06 | | vibes43: Got it. Great puzzle. Easier than yesterday because less going on. |
|
| Mar-30-12 | | Naniwazu: Found this game in an old book called 'Chess Sparks' (Ellis, 1895). Nice little Queen sac to deliver mate in two. |
|
| May-10-12 | | Abdel Irada: Should such a sacrifice be Legal? ;-) |
|
| Oct-17-16 | | Aunt Jemima: 11. Na4 looks like a real howler. I have to admit, I didn't see blacks queen sac. White deserved to lose after playing his Knight to h4. |

 | | tpstar: "Center Holding Variation" would nowadays be called a Strong Point line where Black supports and maintains the Pe5 with ... Qe7 & ... d6 instead of trading ... exd4. After 11. Nh4? Black had 11 ... Bxf2+! swiping a Pawn while preventing White from castling; 12. Kxf2 Nxe4+ 13. Nxe4 fxe4+ 14. Kg1 Qxg5 and Black is better. |
|
| Dec-27-18 | | HarryP: Nice! |
|
| Jan-13-23 | | generror: As others have pointed it, it is a well-known trap, and I was surprised that Horwitz -- who wasn't a bad player -- fell for it, but then this was very early in his career. Pinning the king's knight to the queen while the king's bishop is staring at your f-pawn is -- at best -- a lost pawn, as was already demonstrated in Ruy Lopez vs G da Cutri, 1560. This variation, with the castled rook coming into play with an open f-file, is especially effective, leading to a very sudden death. Probably the best example for the backfiring weak pin. |
|
| Jan-13-23 | | generror: Oh, and <11...Bxf2+!> is already winning. After <12.Kxf2 Nxe4+ 13.Kg1 Qxg5 14.Nhf3 Qe3+ 15.Kh2 Qf4+ 16.Kg1 Ng3 17.Nf1 (17.Rh2?? Qe3#) Nxh1 18.Kxh1> (D), Black will be up an exchange and two pawns. 
click for larger viewAfter <12.Kf1 fxe4 13.Kxf2 Nd7+ 14.Nhf3 Qxg5 15.Nxe4 Qh4+ 16.g3 Qxe4 17.Bd3 Qxf3+ 18.Qxf3 Rxf3+ 19.Kxf3> (D), he has two knights and a (passed) pawn for the rook, with the black king in the middle of the board.
