 | | notyetagm: With 45 ...  f7!, Black uses the looseness of the f7-pinning square to create a winning skewer. So 45 ... f7! is classified tactically as a <DECOY> into a <SKEWER>.White resigns because he loses queen for rook after 46  xf7 f1+ and 47 ... x. |

| | ahmadov: Until the end I thought that Pono has the upper hand in this game. Moreover, it was Mamed who was under time pressure. How could Pono blunder his queen? |

| | notyetagm: <ahmadov> Another example of this exact same tactical theme occurred at the Turin Olympiad in R Prasca vs Baburin, 2006. In that game White lines up his king and queen with 53  f3??, just like Ponomariov did in this game with 45 f4??. Baburin's 53 ...  c6! is the exact same tactic as Mamedyarov's 45 ... f7!, a <DECOY> which creates a <SKEWER> along the line of the king and queen, dragging the queen from a square where she is defended to one where she is not. |

click for larger viewA third example of this tactical theme can be found in the position above, from the 1999 World Junior Championship. There the <DECOY> into a <SKEWER> occurs after Black has foolishly lined up his king and queen along the open b-file with 32 ... b5??. Once again the Lady vanishes after 33 b3! x 34 b8+ and 35 x.

| | notyetagm: One more example of the theme, from the 2004 Calvia Olympiad in Short vs S Azarov, 2004. Here Nigel was forced to resign after 58 ... a1! since, once again, the Lady vanishes after 59 x h1+ and 60 ... x. |

| | ahmadov: <notyetagm> So, we can consider you a specialist of this theme ;). |

| | notyetagm: <ahmadov> More of a specialist than poor Ponomariov! :-) |

| | ahmadov: <notyetagm> From your nick I can guess that you are working hard to become a GM. Exploring this theme is just one step forward in achieving this. Please, change your nick as soon as you become a GM and challenge me at gameknot so that I can learn some chess from you. Good luck! |

| Jan-22-08 | | PAWNTOEFOUR: <notyetagm>.........nice tactic!...i couldn't see it at first,but crafty found it less than a nano second......as you can see,i'm still an international grandpatzer |
|
| Jul-19-08 | | The Ninth Pawn: From Game Collection: The Ninth Pawn's Chess Course : In Ponomariov vs Mamedyarov, 2006 , the White queen and king are dangerously lined up for pins/skewers, as Black demonstrates with 45. ... g7-f7! because after 46. f5xf7, d3-f1+ picks off Her Majesty. |
