| Sep-25-13 | | morfishine: It looks like Black is generating some threats and has cemented his defense; but then his position is hit with <29.Nxd6+> After 29...Qxd6 30.Bxe5 Qe6 31.Rxf6+ Qxf6 32.Bxf6 Kxf6 33. Qd6+ and Black's position collapses; or (1a) 31...Qd7 31.Rxf6+ Ke7 32.Rbf1 Rh7 33.Bd6+ Kd8 34.Rf8+ Rxf8 35.Rxf8+ Qe8 36.Rxe8+ Kxe8 37.Bxc5 *****

 | | Domdaniel: Aha, the old Hyperaccelerated Pterodactyl, Exchange, aka the Speeded-up Wing-finger Swap. Think of an extinct flying lizard with a heat-exchange engine mounted on its tail. |
|
| Sep-25-13 | | Abdel Irada: <Think of an extinct flying lizard with a heat-exchange engine mounted on its tail.> The prehistoric equivalent of Wile E. Coyote. No wonder it became extinct. ∞ |

| | Domdaniel: Or Evel Knievel in a leather bat costume? |
|
| Sep-25-13 | | Abdel Irada: <Domdaniel: Or Evel Knievel in a leather bat costume?> Well, he's extinct, too....

|
| Sep-25-13 | | framsey: Lots of people saying this was easy for a Wednesday. I'm not so sure. I saw the idea straight away, and calculated the game continuation, but it's not immediately clear that the ensuing position is winning. I thought that 32...Nxd3 gave black the best chance. |
|
| Sep-25-13 | | Abdel Irada: <Well, he's extinct, too....> Now, this is strictly between us, <Domdaniel>, but apparently Wile E. and Evel both got their equipment from the same company. (Of course, part of the settlement in the lawsuit I'm not allowed to mention requires a permanent gag order, so I can't name the company; I can only hint that its name resembles "acne.") ∞ |

| Sep-25-13 | | kevin86: The focus of this one is f6 and the target is black's queen. |
|
| Sep-25-13 | | GrandMaesterPycelle: how I wish I could one day claim to be an expert in the hyperaccelerated Pterodactyl... |
|
| Sep-25-13 | | patzer2: Despite its unconventional appearance, Black actually comes out of the opening in this game with a strong advantage after the first 20 moves. In fact one could argue it was the conventional looking move 25...Rag8?! that cost Black the game, or at least caused him to lose most or all of his advantage. Instead of 25...Rag8?!, the backward developing 25...Nc8! (position below) would have been much stronger, and more in character with the game Black had played so far. 
click for larger view(Position after 25...Nc8!)
Here (after 25...Nc8!), Black has a solid extra pawn and the Knight will soon go to e7 to give Black a rock solid and safe King position, with no pawn weaknesses. White, with three isolated pawns and almost no compensation, is lost after it gets to an endgame. Fritz 12 gives Black just over a 1.5 pawn advantage after 25...Nc8!  to  . One possibility, played out move-by-move on Fritz 12, is 25... Nc8! 26. Qg3 Ne7 27. Rbe1 Rh5 28. h3 Qa7+ 29. Kh2 Rah8 30. Nf3 Nc5 31. Nd2 Qd7 32. Re2 Ne6 33. Kg1 Rg5 34. Qe3 d5 35. Nf3 d4 36. Qd2 Rgh5 37. Bc4 Nf4 38. Nxd4 Nxe2+ 39. Bxe2 exd4 40. Bxh5 Rxh5 41. Bxd4 Ng8 42. Rf4 Qe6 43. c3 bxc3 44. Qxc3 Rb5 45. Qc1 g5 46. Rg4 Kf7 (-4.42 @ 20 depth, Fritz 12). |
|
| Sep-25-13 | | patzer2: Of course Black's biggest mistake was 28...Nc5?, overlooking 29. Nxd6!  .Instead, 28...d5!  to still leaves Black in the game. |
|
| Sep-25-13 | | BOSTER: No any agressive player will simply exchange his bishop even for an opponent's rook, and he will not even consider exchanging one for enemy
knight.
To give up the Indian's bishop at g7 when the black pawn's structure looks like in "Robatsch", and playing against Robatsch this is the
double chance to loose the game. |
|
| Sep-25-13 | | LIzzard: Could black have played Qe7 instead of Qe6? Lives to fight on in some capacity.. |
|
| Sep-25-13 | | ZZpatzer: I found this one difficult to win against crafty...http://www.chessvideos.tv/endgame-t... |
|
| Sep-25-13 | | bachbeet: I saw the weakness at f6 and figured out the moves which win the Q. |
|
| Sep-25-13 | | SamAtoms1980: <LIzzard: Could black have played Qe7 instead of Qe6? Lives to fight on in some capacity..> 30....Qe7 31.Bxf6, and it doesn't look pretty... |

| | Domdaniel: <BOSTER> A good player, whether aggressive or not, should consider *all* exchanges, even if they seem to give up a good piece for a lesser one. It's the resulting positions that matter. <patzer2> I agree, ...Nc8 is a strong move. I only saw the idea a couple of moves later, when it was too late to hold the game. But your idea works, I reckon. |

| | Domdaniel: BTW, is the Hyperaccelerated Pterodactyl an ancestor of the Dragon, or vice versa? |
|
| Sep-25-13 | | LIzzard: Samatoms1980,
Thanks - for some reason I was stuck on Rxf6+ and couldn't consider the obvious alternative. That sequence ends up with white up material, but not a good decisive kind of point that I bxf6 produces. Appreciate the help!
Cheers

| Sep-25-13 | | dark.horse: I saw the line played. After 32...Kxf6 the black pieces on the Q-side are sitting ducks. |
|
Sep-25-13
 | | Penguincw: Total shocker from what I was thinking (something to do with a queen sac). |
|
| Sep-25-13 | | nariga: 29. Nxd6 Qxd6 30.Bxe5 Qd7 31. Bxf6 Nxd3
32. cxd3? Rh6 and now the black rooks are safe |
|
| Sep-25-13 | | actinia: the only line that hasn't been addressed is 29. ... Kg7, which should be met by Bxe5 |
|
| Sep-25-13 | | thegoodanarchist: <Domdaniel: Or Evel Knievel in a leather bat costume?> That is safer than a silk bat costume any day.... |
|
| Sep-25-13 | | thegoodanarchist: Of course ...Kf6 is followed by Qd6+ and a rape of Black's queen side pieces. |
