Jul-28-08 | | shr0pshire: Good fight, but this probably was drawn after move 25, but I don't have a board to find out the fatal mistake by Pelletier. |

 | | kamalakanta: Starting with 28. Rb7 Leinier outplayed his opponent. As a matter of fact, all the simplifications leading to the 25th move were brilliant. Material is even, but White has a centralized Queen, and a rook already in an open file. Capablanca would be proud of him. Also Chigorin, who was, like Leinier, very good maneuvering with the knights! |

 | | kamalakanta: 27...h6 was necessary, giving some breathing room to the King. |
|
Jul-28-08 | | Bobsterman3000: Doesn't this look somewhat salvageable for black until 41...Re6, an obvious blunder that loses a pawn immediately. |

Jul-28-08 | | 4tmac: White's position is hanging? You forgot who is working the R+N. click for larger view. R-c7+! and black resigns 5 moves later. |

Jul-28-08 | | messachess: Yeh, 51.Rc7+ was a real pretty move to find. If...KxN, 52.f5+ Rxf5 53.Pxf5, and the <a> pawn falls to the white R. Nice. |

Jul-29-08 | | euripides: Why not 47...Nxa5 ? During the game we looked at 48.g4+ Ke6 49.Ra4 winning the a pawn. If 49...Nb3 then 50.Rxa6+ Ke7 51.Ra7+ Kd6 52.Rxg7 Rxf4 53.Nf7+ winning the h pawn, when Black's activity doesn't seem sufficient compensation for the two pawns. But if 49...Nb7 50.Rxa6 Ke7 51.Ra7 (perhaps Ra4) Rb6 Black might hold. |

Jul-29-08 | | madlydeeply: This IS a Capablancesque game. Mark my words, Dominguez-Perez is ambitious. We will see more of him in the future. I'm starting to be smitten...sigh. |

Jul-29-08 | | percyblakeney: The Rf8-a8-c8-e8 thing just before the first time control looks strange and loses lots of time. 38. ... Rb8 looks like a safe way to quickly exchange down to a drawn endgame (if 39. Nd4 it's just to play Rb1+ followed by Ra1 and picking up the a-pawn). |

does Dominguez (White) retreat the threatened White g6-knight? White to play: 51 ?
 click for larger viewNo, Dominguez plays the excellent tactical shot 51 ♖c6-c7+!. Position after 51 ♖c6-c7+!

<51.Rc7+! Nice trick: Black cannot play 51...Kxg6 because of 52.f5+ Rxf5 53.gxf5+ Kxf5 54.Rc6+–. Now the king should go to g8, but a discouraged Pelletier takes the wrong path and runs into a dashing attack by his Cuban opponent:> So the tactical point of 51 ♖c6-c7+! is that it makes the White g6-knight <TABOO>. Dominguez is using the tactical idea that I call <YOU CANNOT GO FORWARD IF YOU CANNOT GO BACK>, or
<IF YOU ARE ATTACKED, YOU MUST GO BACK>. This idea is very clearly explained by this variation. If Black captures the White g6-knight with 51 ... ♔f7x♘g6??, then the Black king
has gone _FORWARD_ to the g6-square but His Majesty cannot go _BACK_ the way he went
forward (he cannot _BACKTRACK_) because the White c7-rook denies Him access to the f7-square. Not only is the
f7-square cut off by the White c7-rook but also so are the g7- and h7-squares. In fact
not only does the Black g6-king have <NO RETREAT> after 51 ♖c6-c7+! ♔f7x♘g6?? but he is also
<STALEMATED>.
The simple winning variation after 51 ... ♔f7x♘g6?? given on the chessbase site is shown below. (VAR) Position after 51 ... ♔f7x♘g6?? 52 f4-f5+ ♖f6xf5 53 g4x♖f5+ ♔g6xf5 54 ♖c7-c6

Aug-11-08 | | notyetagm: <The important question regarding <PIECE SAFETY> that you have to keep in mind at _ALL_ times is as follows: <<<if a piece moves forward from a square it cannot go back to and it gets attacked, then where can it safely go?>>>. Often the answer is nowhere! <<<WETESCHNIK> says very clearly that before you put a piece on a square or _COMMIT_ a piece to a square, you must have a plan to retreat that piece to safety if it gets attacked, else your piece can be <TRAPPED> and the game is almost certainly lost.>>> This neat tactical device (attacking a piece (51 ♖c6-c7+!) so that it cannot go forward (51 ... ♔f7x♘g6??) because it has no retreat (flight) squares) makes
it impossible to sometimes defend a square or piece indirectly by making it taboo, as Dominguez does here
with the excellent 51 ♖c6-c7+!, gaining the <7TH RANK> with a <GAIN OF TEMPO> and indirectly
<DEFENDING> his White g6-knight to boot. |
