 | | Honza Cervenka: If 17.Qxb4, then 17...Nxd3+ 
10.h4 seems to be dubious. 10.0-0 would have been certainly better. |
|
| May-26-03 | | Cerebrate2006: Why not 17. Rc3? I know i am missing something, but what? |
|
May-26-03
| | Honza Cervenka: If 17.Rc3, then 17...Nxd3+ (The rook is pinned.) |
|
| May-29-03 | | Cerebrate2006: Wow, see what i get for thinking early in the morning, thanks |
|
| May-29-03 | | drukenknight: 8 Qb3 e6 9 Bb5+ may be sharper. |
|
| May-30-03 | | Cyphelium: Why answer 8.Qb3 with 8.-e6, What's wrong with castling? |

 | | Phony Benoni: Hmm. 16...Nxd3+ clears the way for a queen check on g3, but that mean anything. Just for the fun of it, what happens if we check with the queen first instead? Well, <16...Qb4+ 17.Qxb4 Nxd3+ wins a piece, but White doesn't have to take the queen. But in that cae, we destroy the protector with 17...Qxb3 and the bishop falls anyways, since White can't get out of check and protect it at the same time. |

 | | Penguincw: Yay, I got this puzzle! I also thought of 16...Nxd3+ and 16...Qg3+??, but ended up finding 16...Qb4+ 17.Qxb4 Nxd3, queen lost. If white declines the queen, then the bishop falls (taking on b3, then d3). 17.Rc3 puts the rook into a pin, and 17...Nxd3+ is coming with check (and then the rook falls). Same thing if 17.Qc3 (17...Nxd3+, then queen falls, bishop on g7). 2/2 this week? |

| Sep-06-16 | | stacase: Somebody put up a little rhyme the other day about seeing a fork and you'll be happy the rest of the day or something like that. Well anyway, once you see the nasty little game that the Knight in the middle of the board is always up to, all you have to do is get White's Queen to comply. Ha, 16...Qb4+ and you're up a Bishop |
|
| Sep-06-16 | | dfcx: white's bishop is only protected by the queen.
16...Qb4+
A. 17.Qxb4 Nxd3 forks the queen and gains a piece B, 17.Rc3 Nxd3 18.Qxb4 Nxb4
C. 17. other moves Qxb3 18.axb3 Nxd3 still wins the bishop. |
|
| Sep-06-16 | | Cheapo by the Dozen: Sad to say, but at this stage of my life I might have missed that shot over the board. Since it was a puzzle, however, I kept looking until I found the answer, perhaps spending a full minute to find it. |

 | | gawain: 16...Nb4+ wins a piece! White is forked. |
|

 | | Infohunter: <dfcx> After 17.Rc3 it's 17...Nxd3+, so 18.Qxb4 is not an option. |

 | | agb2002: The material is identical.
White has the threat 17.Bc5 Nxd3+ 18.Qxd3 Qe5 19.f4 and 20.Bxe7. The black knight is close to White's royal family and to the rook on c1. This leads to 16... Qb4+: A) 17.Qxb4 Nxd3+ 18.Kd2 Nxb4 - + [B] and White doesn't have enough compensation for the piece. For example, 19.Bc5 Na6 20.Bxe7 Rdc8, etc. B) 17.Bd2 (or 17.Nc3) 17... Qxb3 18.axb3 Nxd3+ and 19... Nxc8 - + [R+B vs N]. C) 17.Kd(f)1 Qxb3 18.axb3 Nxd3 - + [B]. |
|

| | agb2002: I forgot
D) 17.Rc3 Nxd3+ followed by 18... Bxc3 winning a whole rook. |

 | | mig55: You can start the puzzle already with 15.../ Black to play, after ...b5, Rb8, and after a4, a6... |
|
| Sep-06-16 | | ozu: Took a few minutes..lot of moves looked like they should be the right one...These puzzles have really helped me strengthen my chops over the last couple years..even if I'm looking at them only sporadically..Many Many Thanks CHESSGAMES.COM. I'm really proud to be associated with this website! |

| Sep-06-16 | | saturn2: Got Qb4+. Was not there a similar trick in a Keres game on one of the recent thuesdays? |
|
| Sep-06-16 | | aidanmurph64: Took me a few minutes but Qb4+ wins a piece. |

 | | Once: Ah, it's a PPP - piece protects piece. We should always get interested when we attack a piece and it is only defended by another piece. Can that second piece be deflected or destroyed, leaving the PPP piece dangling? I sometimes get the image that there is a rope between the pieces who are protecting each other. All I need to do is to cut that rope ... |
|
| Sep-06-16 | | AlicesKnight: Hmmm - it looks as if ....Qb4+ wins a piece. If white takes, ...Nxd3 forks the Q, and if white moves the K, Black exchanges Qs and then takes the d3 bishop. Let's see - yup. |
|
| Sep-06-16 | | gofer: <16 ... Qb4+> wins a piece at least. The most <alluring> defensive moves; <17 Rc3> and <17 Bd2> lose a piece and an exchange! So white has to choose between <17 Qxb4 , 17 Kd1 and 17 Kf1> which loses less... ...but still loses... |
|
| Sep-06-16 | | kulitbulilit: Nice to see a gem of a game by a Filipino player of long ago, against the great Hungarian master Portisch. |
|
| Sep-06-16 | | patzer2: It's Tuesday and 16...Qb4+ solves our puzzle by overworking the Black Queen as 17. Qxb4 Nxd3+ 18. Kd2 Nxb4 (-3.54 @ 27 depth, Stockfish 7) wins decisive material with a knight fork. If 17. Kf1, then 17...Qxb3 18. axb3 Nxd3 19. Rd1 Ne5 (-3.67 @ 20 Depth, Deep Fritz 15) removes the Queen's guard and wins the Bishop using the deflection tactic. If 17. Qc3, then 17...Nxd3+ 18. Kd2 Bxc3+ (-14.65 @ 18 depth, Deep Fritz 15) wins the White Queen utilizing the pin and discovered attack with check tactics. White's decisive mistake was 15. f3? allowing the winning deflection 15...b5! (-3.11 @ 28 depth, Komodo 9.42). If 16. Bxb5, then 16. Bxb5 Bxb5 17. Qxb5 Rab8 18. Qa4 Nd3+ 19. Kd2 Nxc1 wins the exchange with decisive advantage. Instead of 15. f3?, White should play 15. Bb5 = to  (-0.22 @ 28 depth, Komodo 9.42) to keep it about level. Earlier, instead of the weakening 13. d5?! Ne5 (-0.36 @ 21 depth, Deep Fritz 15), White should maintain the tension with 13. Qb3 e6 14. e5 = to  (+0.27 @ 21 depth, Deep Fritz 15). |
|
| Sep-06-16 | | patzer2: <Once> My grandson's refer to PPP as putting pressure on the pinned piece. I think they got it from a chesskid.com online video. |
